TROPICAL WAVES...
AN ATLANTIC OCEAN TROPICAL WAVE IS ALONG 17N39W 12N41W 5N42W

THE CAPE VERDE ISLANDS AND THE WIND SHIFT FROM 700 MB TO
600 MB FROM A FEW DAYS AGO SEEMS TO INDICATE THAT THE WAVE
PASSED THROUGH THERE. CYCLONIC TURNING IS APPARENT IN THE LOW CLOUD FIELD ON VISIBLE SATELLITE IMAGERY. SCATTERED MODERATE

Friday
Rain showers likely in the morning...then rain showers likely and chance of thunderstorms in the afternoon. Breezy. Some thunderstorms may produce gusty winds in the afternoon. Highs in the lower 60s. Southwest winds 15 to 25 mph. Gusts up to 40 mph in the afternoon. Chance of showers and thunderstorms 70 percent.
Compared to this I think your outlook is not all that bad.
Statement as of 12:35 PM CST on November 29, 2006
A Winter Storm Warning remains in effect from 6 PM this evening
to 3 am CST Friday for the following counties...
In Arkansas...
Benton.
In Oklahoma...
Craig... Ottawa... Tulsa... Rogers... Mayes... Delaware... creek...
Okfuskee... Okmulgee... Wagoner... Cherokee... Adair... Muskogee...
McIntosh... and Pittsburg.
A powerful cold front was spreading across the warning area
today with temperature falling rapidly as the wind shifts
to the north. Rain and thunderstorms were developing and
expanding along and behind the front. This evening temperatures
will begin to fall below freezing while the rain and
thunderstorms continue. This will result in periods of freezing
rain or sleet tonight. Thunderstorms may persist while the
surface temperature GOES below freezing and this could cause
damaging ice accumulations in parts of the area tonight.
Initially the ice glaze will affect only elevated objects... but
as the temperature falls below 29 degrees the ground and Road
surfaces will also see ice accumulations.
On Thursday... snow will develop and be heavy at times. Accumulations
of 4 to 6 inches are likely along and north of a line from
Henryetta Oklahoma to Springdale Arkansas with a zone of 6 to 8 inches
of snow possible along the I-44 corridor... including Tulsa... with
local amounts to 10 inches in extreme northeast Oklahoma.
Travel could become nearly impossible on Thursday in parts of
northeast Oklahoma as winds increase and casue some blowing and
drifting of the snow.
Preprarations for this now dangerous storm should be rushed
to completion. This includes ensuring an adequate supply of
vital items like medications and baby supplies and being ready
for possible power interuptions.
