Area forecast discussion, Nov 12, 2:22 PM CST, 42 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FORT WORTH TX
222 PM CST FRI NOV 12 2010

.DISCUSSION...
STRONG COLD FRONT NOW ENTERING WRN NORTH TEXAS ATTM...WITH STRONG
COLD ADVECTION NOTED UPSTREAM. MEANWHILE...MAIN SHORTWAVE TROUGH IS
CURRENTLY LIFTING THROUGH NRN OK/KS WITH ENERGY TAILING ACROSS NORTH
TEXAS. WARM SECTOR LINEAR CONVECTION IS NOW MOVING INTO ERN COUNTIES
WITH A EMBEDDED STRONG STORMS EXPECTED...THOUGH CAN'T RULE OUT A
MARGINALLY SEVERE STORM WITH BREAKS IN CLOUDS ALLOWING FOR
INSTABILITY HOLES WITH CAPE VALUES BETWEEN 500-1000 J/KG. SECONDARY
LINEAR LINE BUILDING SOUTH ALONG MAIN FORCING/COLD FRONT IN SRN OK.
THIS WILL LIKELY PUSH ACROSS THE RED RIVER VALLEY THROUGH THE HWY 82
CORRIDOR AND DOWN TO THE HWY 380 CORRIDOR ACROSS NE PARTS OF NORTH
TEXAS LATE THIS AFTERNOON AND EARLY EVENING WITH MORE SHOWERS AND
STORMS. CAN'T RULE OUT SOME GUSTY WINDS AND BRIEF HEAVY RAINFALL
WITH SECONDARY LINE. BACK ACROSS NW COUNTIES...SOME WRAP-AROUND
PATCHY LIGHT RAIN IS POSSIBLE THROUGH THIS EVENING...AS THE SYSTEM
LIFTS AWAY.

COOL...BRISK...AND GUSTY WEST AND NORTHWEST WINDS WILL INFILTRATE
THROUGH NORTH TEXAS TONIGHT...BEFORE GRADUALLY WEAKENING WITH
DECOUPLING AND WEAKENING PRESSURE GRADIENT EARLY SATURDAY MORNING.
NEXT SHORTWAVE ARRIVES OVER TX SUN AFTERNOON/NIGHT...HOWEVER BEST
MOISTURE DEPTH WILL RESIDE OVER S/SE TX AND DESPITE INCREASING
ISENTROPIC UPGLIDE OVER TOP OF FRONTAL INVERSION...THE AIRMASS WILL
BE DRY OUTSIDE OF ABOUT THE SE THIRD OF NORTH TEXAS. WE WILL HAVE
CHANCES FOR SHOWERS ACROSS THOSE AREA INTO MONDAY MORNING. SOME
UNCERTAINTIES ON MOISTURE AVAILABILITY ALOFT FOR A THIRD SHORTWAVE
ARRIVING ON MONDAY NIGHT/TUES MORNING....BUT WOULD EXPECT MORE OF AN
ELEVATED/VIRGA SCENARIO AND WILL HAVE NO MEASURABLE RAINFALL IN THE
FORECAST. THE VIRGA AND CYCLONIC FLOW ALOFT OVERHEAD WILL FALL-LIKE
CONDITIONS MOST OF THE WEEK. TEMPERATURES WILL STRUGGLE ONLY INTO
THE 50S/60S OVER THE WEEKEND...TO POSSIBLY 60S OR AROUND 70 SOUTH OF
I-20 BY TUES/WED.

ANOTHER COLD FRONT ARRIVES WED NIGHT INTO THURSDAY...BUT WITH DRY
WNW/CYCLONIC FLOW ALOFT...SHOULD DO NOTHING MORE THAN REINFORCE THE
FALL-LIKE TEMPERATURES UNDER SUNNY-PARTLY SUNNY SKIES WITH HIGHS
BACK DOWN INTO THE 60S. MODIFIED GULF MOISTURE RETURNS NWD BY NEXT
NEXT WEEKEND...BUT FAST ZONAL FLOW ALOFT ALOFT OVERHEAD SHOULD
MAINTAIN DRY CONDITIONS FOR THAT PERIOD.
