Dr. Jeff Masters' WunderBlog

A Tale of Two Invests
Posted by: Dr. Jeff Masters, 12:17 GMT le 04 juillet 2010 +2
Good morning, everybody, Dr. Rob Carver filling in for Jeff on Independence Day.

Currently, NHC is monitoring two different areas for possible tropical cyclone development. Invest 95L is about 125 miles west-southwest of the mouth of the Mississippi and it doesn't have much thunderstorm activity associated with it. Dry air from the north and strong wind shear have weakened it considerably from yesterday, and NHC believes it has a 10% chance of becoming a tropical cyclone before the feature makes landfall.

Invest 96L is in the western Caribbean sea and bears watching closely. Earlier in the morning, the convection was all on the east side of the circulation center, but thunderstorms have developed on the southwest side. According to the CIMMS wind shear analysis, 96L is on the outskirts of a low wind shear region just east of the Yucatan peninsula. It's also over warm SST's (>29 deg C), so it could intensify. NHC gives it a 20% chance of becoming a tropical cyclone in the next 48 hours. Computer models have 96L going through the Yucatan Channel then turning left and making landfall somewhere near the Rio Grande.

Next Update
My next post will be sometime Monday afternoon/evening. If the situation changes significantly before then, I'll make a new post. In any event, enjoy the holidays...

The most I could see 96L at the point in time is a 40mph TS and I'm being aggressive.

HWRF takes 96L through the northernmost tip of the Yucatan as a strong tropical storm/weak hurricane and then to Texas. On its way to Texas it remains as a weak system in the GOM because of low TCHP.


do we most go overe the TCHP thing how many times have i been trying too say it

The SHIP was the most aggressive with Alex, as it is again with 96. BUT, it was the only one that was right with the strength.

Eh, I think it could get somewhat stronger than that. Its all going to depend on how fast it organizes. If it becomes a tropical depression tomorrow, I easily see it being a moderate tropical storm.

I'm thinking of a more northerly track, instead of a Mexico landfall this one might threat Texas. Also, 96L will be weaker than Alex because Alex drained the Gulf of heat content.

I think the CMC is moving 96L too fast. The ECMWF on the 00z run didn't have it making landfall till around 144 hours.

Oh Houston doesn't need anymore right now. Katy still may be under water.

Further down the coast, putting the heaviest rain to your west, that would be ideal, giving S Central TX into N & NE TX a good dose of rain.

From the "Ghost of Alex" & the weak surface boundary the Arlington Municipal AP has 4.70" of rain, from 6-28 through 7-3-10. We need another 2-4" to catch up to "normal" for the year.

That's true, but it doesn't have a surface low level circulation, so unless it organizes quite rapidly and develops a closed surface low by tomorrow it is unlikely it will be a TD tomorrow. Either way, I do think that 96L will eventually become Bonnie, but not in the next 30 hours.

guys.... Alex absolutely drained the gulf of mexico of warm waters... 96L may develop into a tropical depression or even a tropical storm... but it will not measure up to Alex.... unless it stalls or something and lets the heat content build back up

Just before that it had winds of TS strength, they were probably far away from the inner nest so thats probably why it disipated it.

TROPICAL WEATHER OUTLOOK
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
200 PM EDT SUN JUL 4 2010

FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...

THERE HAS BEEN LITTLE CHANGE WITH A SMALL NON-TROPICAL AREA OF LOW
PRESSURE LOCATED ABOUT 115 MILES SOUTH-SOUTHWEST OF THE MOUTH OF
THE MISSISSIPPI RIVER. THIS LOW IS EXPECTED TO MOVE GENERALLY NORTH
OR NORTHWESTWARD AT 5 TO 10 MPH OVER THE NEXT COUPLE OF DAYS.
ENVIRONMENT CONDITIONS ARE NOT CONDUCIVE FOR DEVELOPMENT...AND
THERE IS A LOW CHANCE...10 PERCENT...OF THIS SYSTEM BECOMING A
TROPICAL CYCLONE BEFORE IT MOVES INLAND ON MONDAY.

SHOWERS AND THUNDERSTORMS ASSOCIATED WITH A TROPICAL WAVE OVER THE
NORTHWESTERN CARIBBEAN SEA HAVE BECOME A LITTLE BETTER ORGANIZED
AND SURFACE PRESSURES ARE BEGINNING TO FALL IN THE AREA.
CONDITIONS APPEAR FAVORABLE FOR SOME DEVELOPMENT OF THIS SYSTEM AS
IT MOVES GENERALLY WEST-NORTHWESTWARD AT ABOUT 15 MPH OVER THE NEXT
COUPLE OF DAYS. THERE IS A MEDIUM CHANCE...30 PERCENT...OF THIS
SYSTEM BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE
NEXT 48 HOURS.
