MESOSCALE DISCUSSION 0183
NWS STORM PREDICTION CENTER NORMAN OK
0901 PM CST FRI FEB 23 2007

AREAS AFFECTED...ERN OK/TX PANHANDLES/WRN OK/TX SOUTH PLAINS

CONCERNING...TORNADO WATCH 27...

VALID 240301Z - 240430Z

SEVERE THREAT CONTINUES ACROSS MUCH OF TORNADO WATCH 27 -- WHICH
WILL LIKELY BE REPLACED SHORTLY WITH TORNADO WATCH 29.

LATEST RADAR/SURFACE OBS REVEAL THAT THE DRYLINE IS NOW RETREATING
WWD ACROSS THE CENTRAL TX PANHANDLE...AS SURFACE FLOW BACKS AHEAD OF
APPROACHING UPPER TROUGH. INITIAL SEVERE/SUPERCELL STORMS HAVE
MOVED NEWD INTO NWRN OK AND NNEWD INTO SWRN KS...BUT NEW STORMS HAVE
DEVELOPED ACROSS WHEELER/GRAY/DONLEY COUNTIES...NEAR RETREATING
DRYLINE. EXPECT CONVECTIVE COVERAGE TO INCREASE ACROSS THE TX
PANHANDLE AND INTO WRN OK -- AND ACROSS NEWLY-ISSUED TORNADO WATCH
28 ACROSS WRN KS -- OVER THE NEXT FEW HOURS AS STRONGEST UVV ALOFT
SHIFTS ACROSS THIS REGION. COMBINATION OF MARGINAL INSTABILITY AND
INCREASINGLY-STRONG DEEP-LAYER SHEAR SUGGESTS THAT SEVERE/SUPERCELL
THREAT WILL CONTINUE...WITH STORMS LIKELY TO ORGANIZE INTO A LINE
WITH TIME AS COLD FRONT MOVES EWD AND OVERTAKES THE RETREATING
DRYLINE LATER TONIGHT.

I've been reading AFDS and Special Weather Statements for Saturday's potential outbreak over LA, AR, and MS.. and maybe TN, AL, MO, and FL.

Shreveport's lastest AFD sounded like they were pretty concerned, especially for areas east of the Shreveport area.. and Memphis put out a SWS about 40 minutes ago saying that tornadoes were possible over NW Mississippi and east central Arkansas between 4 and midnight tomorrow.

NWS in Jackson, Mississippi is forecasting "widespread wind damage" and "very large hail" throughout saturday.

Reading the forecast is alarming. Man, I hope this forecast falls apart!

Sitting here waiting for sunrise sort of reminds me of the early morning hours before August 29 several years ago. Wondering if I should go gas up my work truck and load up the chainsaws.

The following post is NOT an official forecast and should not be used as such. It is just the opinion of the poster and may or may not be backed by sound meteorological data. It is NOT endorsed by any professional institution including storm2k.org. For Official Information please refer to the SPC and NWS products.

THIS IS AN EXTREMELY DANGEROUS SITUATION!!!

The first major outbreak of 2007 is developing even before noon, and it is a long steep climb from here. With plenty of daytime heating ahead and a screaming jet stream, I smell something really bad. Violent tornadoes and hurricane-force straight line winds are definitely possible, particularly in the High and Extreme risk areas. Hail isn't a great threat. This evening, I think it will squall back into a derecho.

Farther north over Kansas, low-topped supercells should allow scattered tornadoes to develop there as well. They won't be as strong, but the numbers warrant a Moderate risk there.

If you live in the areas of great risk, you should be caught up on your tornado safety precautions now. Such can save lives and help reduce property loss.

(No hail risk map, in agreement with SPC)

At the present moment I think the immediate coastal areas of MS and AL will have to deal primarily with wind damage and hail, as well as the downpours of heavy rain. An isolated tornado (or 2 or 3) cannot be ruled out, but we're in far better shape in that regard than areas just to the north and west.

IOW, as far as a tornadic outbreak near the coast is concerned...I don't think the dynamics will be in place over the immediate area by the time the primary squall line reaches my stretch of the coast tonight. It's a whole different story just a bit to the north. :eek:

I've been watching this system develop and will update my plans acordingly...but anyone in the temporary FEMA trailers or mobile homes might consider finding safer ground this afternoon and overnight.

I usually dont follow severe weather outbreaks, because I'm not as versed in them as I am in the dynamics of hurricanes. Hoewever, this one directly effects me. I live in Ruston, Louisiana, about 60 miles east of Shreveport as the bird flies. There any chance that I could see some severe weather today? I must say, the winds are really picking up here. It reminds me of a hurricane squall... light rain, real heavy gusts of wind. We've hit 40 mph so far, I think.
