NATIONAL WEATHER SERVICE FORT WORTH TX
1035 AM CST THU MAR 4 2004

.UPDATE...
WE WILL UPDATE THE ZFPFTW TO INCLUDE A HEADLINE FOR TORNADO WATCH
#22...FOR THE PORTION OF NORTH TEXAS GENERALLY ALONG AND NW OF A
LINE FROM K7F9-KDTO. OTHERWISE...NO MAJOR CHANGES WILL BE MADE TO
REMAINDER OF THE FIRST PERIOD FORECAST. WE WILL MAINTAIN CATEGORICAL
POPS FOR ALL AREAS...WITH EXTENSIVE SQUALL LINE NOW DEVELOPING
ACROSS WEST TEXAS FORECASTED TO MOVE NE AND ACROSS MUCH OF THE CWFA.
WELL DEFINED MID-LEVEL DRY SLOT PUSHING INTO WESTERN ZONES MAY AID
IN THE DESTABILIZATION PROCESS ACROSS THIS REGION. IF THIS OCCURS...
LONG/CURVED HODOGRAPHS AND DEEP LAYER SHEAR OF 45-55 KTS...AS WELL
AS SFC BASED CAPE VALUES OF 1000-1400 J/KG STRONGLY FAVOR SUPERCELLS
AHEAD OF THE MAIN SQUALL LINE. THE GREATEST THREAT FOR TORNADOES
WILL COME WITH ANY STORMS DEVELOPING IN THE WARM SECTOR AHEAD OF THE
LINE...WITH DAMAGING STRAIGHT LINE WINDS A GREATER THREAT WITHIN THE
SQUALL LINE. SFC WINDS ARE SLIGHTLY STRONGER THAN INDICATED IN THE
CURRENT FORECAST...AND WILL INCREASE TO 25-35 AND GUSTY. ORIENTATION
OF ISALLOBARIC FORCING WILL ALLOW FOR MORE OF A SE COMPONENT TO WIND
THIS AFTERNOON...AND WILL CHANGE THE FORECAST TO REFLECT THIS AS
WELL.

Hopefully the rest of my teachers would let me keep my laptop out to get more info on this situation.

TexasStooge, where are you? in school? when do you get out? I'll keep ya updated....

Posted: **Thu Mar 04, 2004 1:35 pm**

Be safe guys. Any tornado history associated with this squall line yet?

Posted: **Thu Mar 04, 2004 1:38 pm**

Yes and no. There have been numerous TORNADO WARNINGS but there have been no ground confirmations....

I saw some of your other posts in other threads. I didn't read them until just now. Little early in the season for this kind of weather for North Texas. I always hated seeing those little convective rings near my house on the local TV radars.

Yes, I'm in school and since I have senior out, I get out at 2:45PM CST, so hopefully I'll be in the library by the time this whole thing starts.

Posted: **Thu Mar 04, 2004 1:47 pm**

So you get out in TWO hours? You may be in trouble... STAY SAFE!

Interesting how your teachers allow you to even use a laptop, with or without severe weather.
I would say you obviously can't spend that much time using it between 9:00 am and 3:00 pm.
