Storm reports.
Storm reports. The U.P did not see many severe thunderstorms even though there were warnings issued. Overall the Western U.P got the worst thunderstorms. This is strange because the SPC was forecasting the Southeastern and Central U.P to get sever thunderstorms. The southeastern U.P got only a couple thunderstorms. The Central U.P got a isolated thunderstorm while most areas had little or no rain. The Western U.P got scatterd thunderstorms. Houghton got pingpong ball sized hail. Im sure there was large hail near Watersmeet. The reason the Western U.P got the severe thunderstorms and not the Southcentral U.P was because the best instability passed just to the south. The Western U.P got severe thunderstorms because the low pressure system provided just enought lift for severe thunderstorms. This area of enhanced lift did not make it into the Central U.P thus the thunderstorms died shortly after they developed over the Central U.P. Good day and good night.
Here are some severe weather reports.
The map on top is Friday.
The map second map is Thursday.
The map on the bottom is Wednesday.

Severe thunderstorm update
The SPC put the Whole U.P in a slight risk of severe thunderstorms. New thunderstorms are already developing in Northcentral Wisconsin and will move into the Central U.P around 11:00PM. It looks like the Westcentral and Central U.P have the best chance of severe thunderstorms due to steep mid level lapse rates around 7.C/km, low freezing levels supportive of large hail, and a tongue of instability over wisconsin. The best chances of severe thunderstorms will be between 10:00PM and 1:00AM Saturday because the warm front is close to the U.P. Sever thunderstorms are also occuring in Northwestern Lower Michigan and Eastern Wisconsin. Here is what to expect on the map below. . Stay tuned for updates.
Yellow= Area where severe thunderstorms are possible.
Red= Area where severe thunderstorms are occuring.
Purple= Area where severe thunderstorm development is occuring.

Sever Weather
Severe thunderstorms. Thunderstorms are moving across wisconsin. There is a line of severe thunderstorms in Eastern Wisconsin producing tornados, gusty winds, and very large hail. Around Eagle River Wisconsin a Sever thunderstorms are moving into Gogebic and Iron Counties. These storms could produce golf ball sized hail. The Southeastern U.P has a few thunderstorms with small hail. The Central U.P may not see one drop of rain but the southern end of the line of thunderstorms effecting Eagle River may move into the Central U.P in an hour or so. This is something to watch. Stay tuned for updates.
Thunderstorms and Snow
Snow and Severe weather. Today an area of heavy rain and thunderstorms is moving across Wisconsin. This area of precipitation will move into the U.P tonight. Thunderstorms are developing in Southern Minnesota along a stationary front west of a small dry slot. Some of these storms could be severe. There is a moderate risk of severe thunderstorms in Central Kansas and Southern Nebraska. Right now there are a few severe thunderstorms but as a dry line moves into Kansas this evening thunderstorms will rapidly develop. Tornados are also possible but the best chance of tornados will be in Kansas later this evening. On Friday morning a new low pressure system will develop in Westcentral Kansas and move northeast to Eastern Minnesota or Northcentral Wisconsin Friday night. Severe thunderstorms look likely from Eastcentral Texas to the U.P of Michigan. This area is in a slight risk of severe thunderstorms. There could be tornados in Northern Illinois and Central Wisconsin Friday evening. As for the U.P the severe weather potential depends on the track of the low. The GFS indicates the low will move to around Duluth Minnesota late Friday evening. The NAM shows the low moving near Rhinelander Wisconsin. If the GFS is right the warm front would lift across the Central U.P and bring warmer temps and higher dew points. This would put the Central and Southern U.P in an environment favorable for strong to severe thunderstorms with maybe a supercell with the chance of a tornado. If the NAM is correct the Warm front would only make it into the Southern U.P and there would be a chance of strong thunderstorms. Right now the low looks to move somewhere between Duluth and Rhinelander with strong thunderstorms in the Central and Southern U.P with possibly a few severe thunderstorms. Temperature depends on where the warm front moves. If the warm front does not make it over the U.P expect temps in the lower 60s. If the warm front makes it across the U.P expect temps in the middle and upper 60S. Right now it looks like the U.P will have temps in the upper 50s to middle 60s on Friday. On the other side of the storm Northern Minnesota could get a spring snowstorm with 6 to 8 inches possible of snow. Attention turns toward Monday when a low pressure system moves into the Great Lakes. Earlier this week it seemed the U.P would see some pretty hefty snow accumulations of around a foot. Now their is a trend in computer models to keep the cold air over the U.P and he precipitation over Lower Michigan. The GFS is now trying to develop a snowstorm for Lower Michigan. This is something to watch. LONG TERM: Cold weather 30s and 40s looks to continue until next Thursday. Temps on Thurday will be 45F to 54F. Next Friday and Saturday temps in the lower to mid 60s look possible with showers and thunderstorms. Temps will cool into the 50s between May 4th and 5th. Between May 6th and 10th temps look to range from the lower 60s to lower 70s with the chance of showers and thunderstorms. The map down below shows the risk of severe thunderstorms Friday. The last map down below shows the probability of severe thunderstorms. Stay tuned for updates. Good day and good night.

Snow totals
Snow totals. The storm Friday into Saturday dropped 12 to 14 inches of snow at my house. There was also a little thunder and lightning on Friday morning at my house. Negaunee got 18 inches of snow and so did Copper Harbor. The rest of the U.P got 6 to 12 inches. Temps will get around 65F to 70F Tuesday and Wednesday.

5:00PM snow storm update
5:00PM Snow storm update. Thundersnow coming! A line of thunderstorms will move into the Northcentral U.P this evening producing very heavy snowfall rates. Snow will continue into the night and it could be heavy at times. Marquette county should get around 18 inches total of very wet snow by Saturday morning. I still think there could be 20 inches of snow in the higher terrain of Marquette county. Due to lower snow to water ratios there could be tree and power line damage. The snow is reintensifying due to a redeveloping deformation zone in Northern Wisconsin. Down below is what to expect tonight. I will make a diagram later on how thundersnow forms. Stay tuned for updates. 
12:00PM Snow storm update
Snow storm update. Snow coming to an end in the U.P until this afternoon. Between 2:00AM and 7:00AM 6 to 7 inches of snow fell when a ribbon of elevated instibility, frontogenesis, and upper divergence, moved through. Radar indicated alot of convection this morning. Now the dry slot is moving in. This should lower snow accumulation, but due to the stronger than expected convection and more snow this morning the dry slot will not make a big difference in snow accumulation in areas that got convection. In the dry slot thunderstorms will develop and move into the U.P. Areas that have thundersnow in the dry slot will have higher snow accumulations. Overall snow accumulation will be lower over the whole U.P due mostly to higher snow to water ratios. In Marquette county the higher terrain areas will likely see 18 total inches of very wet heavy snow with possibly 24 if the snow is heavier than expected. heavy snow should redevelope in the afternoon and should continue to 12:00PM Saturday. Depending how the heavy snow band sets up the whole U.P has a chance of more snow than expected with 15 inches in some areas out of lake enhancement. Along Lake Michigan rain should fall most of today. One thing to note is the strong upslope flow in Marquette county. There is no snow band in the central U.P but it's snowing in Marquette county. The lake enhancement will give Marquette county the highest snow totals. Stay tuned for updates.
Yooperland Snowstorm update
Snow storm Update. Winter storm warnings have been issued for much of the U.P of Michigan. Snow will start tonight and continue heavy at times until Saturday evening, especially in the Northcentral U.P. Thundersnow is likely Through tonight and Friday night. Snowfall rates could reach 3 inches an hour tonight into Saturday. The Northcentral U.P could pick up 25 inches of snow with locally higher amounts possible. Blizzard warnings have been issued for Houghton and Keweenaw County. The snow will probably be wet. The NWS office in Greenbay says the U.P could see significant tree and power line damage. It looks like the temperatures will be cooler so the snow will be a little more fluffy and there will be more snow due to higher snow ratios. That would limit damage. The winter storm warning says wet snow though. We'll have to see what happens. Anyway winds will gust to 30 mph from the northeast with gusts up to 50 mph in the Keweenaw peninsula. The storm prediction center puts Menominee in a 5% risk of severe thunderstorms tomorrow, thats interesting. This is a very dangerous snowstorm, heavy snow and strong winds give potential for downed trees and power lines and thundersnow!!! Travel will likely be very dangerous or impossible Friday to Saturday. Down below is my snowfall map. Down below the snowfall map are simulated radar data from the 12:00PM ARW modle update. The radar data images show the best times for thundersnow between 12:00AM Friday and 12:00AM Saturday. Any Yellow or red colors indicate thunderstorms. All the way on the bottom is the GFS total precipitation forcast. Notice the central U.P has two inches of liquid precipitation. If rain fell instead of snow we would would have two inches of rain. Stay tuned for updates. Good day and good night. 
8:00PM Yooperland Storm Update
Snowstorm Update. Last night storm was a dud. I got around 6 or 7 inches at my house. The heaviest precipitation stayed south of the freezing line. The big storm will arrive Thursday night in the Northern Great Lakes. This will be a very big snowstorm for the Western and Northern Great Lakes. Some areas could see almost two feet of snow. Winter storm warnings have been issued in Minnesota and Northwestern Wisconsin. Winterstorm watches have been issued in Northern Wisconsin and the U.P of Michigan. There will also be Northeast winds gusting to 50 mph from Friday to Saturday. Blizzard warnings have been issued around Duluth. In the U.P, Marquette County and Keweenaw County have the best chance of a blizzard warning. Simulated radar data from the NAM and HRW models indicate thunderstorms will get pulled around the low pressure system and thundersnow looks to be a good possibility on Friday. A dry slot will stay just south of the U.P Friday evening. The western and northeast side of the dry slot will be favorable for the development of convection. Any convection in the dry slot will be pulled around the low and areas just north of the dry slot will get thundersnow and snow rates of almost 3 inches an hour. There is the potential still that just rain could fall in most of the U.P but right now it appears to be mostly snow west of a line from Marquette to Iron Mountain. The winter storm watch says around a foot of snow will fall but I think around 15 to 20 inches of snow will fall. A severe Thunderstorm outbreak is starting today and will continue into Saturday. Particularly dangerous situation tornado watches have been issued in Central and Northcentral Texas and Southern Oklahoma. Around Next Wednesday it is going to get warm. Some computer models show temps in the 70s and some show temps in the 40s. It's to hard to tell at this point. Stay tuned for updates. Good day and good night.

10:00PM Yooperland Snowstorm Update
Snow storm update. As of 10:00Pm It is snowing right now. Tonight the snow gets heavy. Look for accumulations of around 6 to 8 inches in the Central U.P and up to 12 to 15 inches in Eastern Baraga County and Marquette County by tomorow afternoon. There could be a few rumbles of thunder along lake Michigan. There will be a mix of rain and snow in the Eastern U.P. The snow will be wet due to temps near freezing so tree limbs could be damaged and there could be power outages. Heavy snow warnings have been issued. Long Term. A major snowstorm looks to be in store for the Western and Northern Great Lakes. It appears a low pressure system will move northeast into Northeastern Iowa Friday Morning and into Central Wisconsin. Even though it will be a little to warm for much lake enhancement there will be so much moisture and strong forcing and some areas in the Western and Northern Great Lakes could see over two feet of snow. Precipitation type will depend on the track of the storm. A farther west track would mean very little if any snow and lots of rain and thunderstorms. A track futher south and east would give the U.P more snow. At this point it appears the Northcentral and Western U.P have the best chance for significant snow accumulations. There is also the potential we could see significant freezing rain and one computer model indicates severe thunderstorms are possible in the U.P. At this point it looks to be mostly snow. This storm will be very significant. Further ahead into April it looks to get very warm with no snowstorms in sight, only thunderstorms. How warm it may get you might ask? It looks to get into the lower 70s for a week starting around April 16th. Stay tuned for updates.

Spring Snow Storms in Yooperland
Snow storms. Northern Minnesota got 30 inches of snow Saturday into today. That storm is not the one that is going to give us snow. In fact the U.P got rain and in the Westcentral and Central U.P there were isolated thunderstorms in the afternoon due to a cold pool aloft. Winter storm watches have been issued by the NWS for Tueday night into Wednesday afternoon. It looks like the Central U.P could see 5 to 9 inches of very wet heavy snow with around 10 inches in the higher terrain of Marquette county, this could cause tree and powerline damage. The NAM computer modle shows 10 to 13 inches of snow will fall. The NWS says this is possible. A major winter storm looks to develope Thursday and move into the Great Lakes Friday. This storm will be most intense over the Great Lakes Friday into Saturday as it stalls somewhere in the Central Great Lakes. If the low stalls, there will be a prolonged period of heavy snow Thursday night into Saturday afternoon especially in the northeast wind snow belts. Snow showers will linger into Sunday. There is the potential that this storm starts out all rain and changes to snow or the U.P gets and ice storm. its to hard to say for sure but it looks like some areas in the Great Lakes could see over 15 inches of snow. There will likely be a sever thunderstorm outbreak in the Central U.S, Southern Great Lakes, and into the Eastern U.S from Monday evening to Saturday. There looks to be a good chance tornados in Southcentral Oklahoma tonight. Stay tuned for updates. Good day and good night.
Yooper Blizzard Snowfall Totals
Snowfall totals. The snow storm was bigger than expected. The NAM was right indicating that 20 inches would fall in Marquette county but the NAM still under estimated the snowfall. About 8 inches of the snow was wet and heavy but the additional 12 inches was fluffy. I should have forecasted more snow in the Northcentral U.P on my snow map. No, it was not an April fools joke for me to forecast around 16 inches when Negaunee got 25 inches. I just did not want people to get to excited because two feet of snow would fall. Actually I was just to lazy to make an updated snowfall map. The snow was not as wet, and thats why we got more snow. The snow ratio went from 10/1 to 15/1. What surprised me was that only a foot of snow was on my deck at 6:00AM. By 12:10PM there was 20 inches of snow on my deck. This storm I believe was the biggest storm of the 2007-2008 Winter, actually now it is spring I just forgot.
