AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
308 PM CST SAT NOV 12 2005

.DISCUSSION...
DRY LINE MAKING PROGRESS EASTWARD AND WAS LOCATED NEAR THE TULSA
METRO AT 3 PM. DEW POINTS IN THE LOW-MID 60S AHEAD OF IT WITH
TEMPS IN THE 70S YIELDING MUCAPES OF 1500-2000. UPPER LOW
CONTINUES TO LIFT NORTHEAST TOWARD THE UPPER MISSISSIPPI VALLEY
LEAVING POTENTIAL FOR THUNDERSTORM DEVELOPMENT UP TO CONVERGENCE
ALONG THE DRY LINE...WHICH HAS NOT BEEN THAT IMPRESSIVE THUS FAR.
ANOTHER LIMITING FACTOR WILL BE LOSS OF DAYTIME HEATING AS WE ARE
NOW AT ABOUT PEAK HEATING TIME. SHEAR PROFILES DO SUGGEST THAT ANY
DEVELOPING STORMS HAVE A GOOD CHANCE OF BEING SEVERE...ESP IF SFC-
BASED. WILL NEED TO MAKE SOME LAST MINUTE ADJUSTMENTS TO FIRST
PERIOD POPS BEFORE SENDING FORECAST PACKAGE.

DRIER AIR WILL SWEEP ACROSS THE AREA TONIGHT WITH STORMS ENDING BY
MIDNIGHT. WITH DIMINISHING WINDS AND DRY LOW LEVEL AIRMASS WILL
COOL OFF NICELY TONIGHT IN MOST OF THE AREA UNDER CLEAR SKIES AND
HAVE UNDERCUT MAV TEMPS SLIGHTLY. HOWEVER NORTH WINDS WILL
INCREASE LATER TONIGHT AND KEEP TEMPS FROM BOTTOMING OUT. NICE
AFTERNOON MONDAY ALBEIT A LITTLE BREEZY.

PRECIP CHANCES RETURN SUNDAY NIGHT AND EARLY MONDAY AS MOIST
SOUTHERLY LOW LEVEL FLOW OVERRUNS SHALLOW COOL AIR WITH DEVELOPING
WARM FRONT LIFTING ACROSS FORECAST AREA IN ADVANCE OF ANOTHER
UPPER SHORTWAVE. EXPECT TO SEE SOME ELEVATED STORMS OVER SOUTH
SECTIONS LATE SUNDAY NIGHT AND SPREAD NORTH DURING THE MORNING.

STRONG COLD FRONT STILL EXPECTED TO ARRIVE SOMETIME MONDAY NIGHT
BRINGING IN COLDEST AIR OF THE SEASON THUS FAR. TIMING OF PASSAGE
IS STILL QUESTIONABLE BUT SHOULD BE THROUGH ALL BUT THE EXTREME
SOUTH BY 12Z TUESDAY. THE REST OF EXTENDED RIDGE AMPLIFIES OVER
THE WESTERN CONUS WITH NORTHERLY FLOW OVER THE PLAINS. A
REINFORCING SHOT OF COOL AIR ON FRIDAY WHICH LOOKS MORE
SIGNIFICANT WITH LATEST GFS RUN. HAVE NOT MADE ANY SIG CHANCES TO
EXTENDED AT THIS TIME..BUT FRIDAY HIGHS MAY NEED TO BE LOWERED.
