Area forecast discussion, Feb 7, 3:07 PM CST, 2 hours 19 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
307 PM CST THU FEB 7 2013

.DISCUSSION...
COLD FRONT IS MAKING SLOW PROGRESS ACROSS THE AREA THIS
AFTERNOON...STRETCHING FROM FAR NWRN AR INTO SCNTRL OK AS OF 21Z.
WIDELY SCATTERED SHOWERS/THUNDERSTORMS NOTED AHEAD OF BOUNDARY IN NW
AR...ALTHOUGH BULK OF PRECIP HAS REMAINED POST-FRONTAL. RAINFALL
AMOUNTS WILL BE A BIT MORE SPOTTY THAN PREVIOUSLY EXPECTED...WITH
GENERAL RAINFALL TOTALS AROUND A QUARTER INCH FOR MOST LOCATIONS AND
LOCALLY HIGHER AMOUNTS IN ISOLATED THUNDERSTORMS. HAVE SEEN A FEW
BREAKS IN THE CLOUDS ACROSS THE SE...AND WARMER/MORE UNSTABLE AIR
LURKING ACROSS SCNTRL OK...SO WILL NEED TO WATCH FOR A POSSIBLE
STRONG/SEVERE THUNDERSTORM THE REMAINDER OF THE AFTERNOON. THE COLD
FRONT AND ASSOCIATED PRECIP WILL SHIFT INTO SE OK/WCNTRL AR LATE
TONIGHT AND SHOULD BE OUT OF FORECAST AREA BY 06-09Z.

NOT MUCH IN THE WAY OF COLDER AIR BEHIND THIS FRONT...THUS FRIDAYS
TEMPS EXPECTED TO REMAIN ABOVE AVERAGE...WITH HIGHS MAINLY IN THE
50S TO LOWER 60S.

LARGE UPPER LOW CURRENTLY ENTERING THE PACIFIC NW WILL DIVE INTO THE
GREAT BASIN AND EVENTUALLY EJECT INTO THE ROCKIES/PLAINS OVER THE
WEEKEND. MAY SEE AREAS OF LIGHT RAIN/SHOWERS DEVELOP BY LATE
SATURDAY MORNING AND INTO THE AFTERNOON AS THE LEAD MID-LEVEL SPEED
MAX PUNCHES ACROSS TX. THIS WOULD PLAY HAVOC ON TEMPS GIVEN THE
INITIAL VERY DRY AIRMASS IN PLACE...WITH WET-BULBING EFFECTS
POTENTIALLY DROPPING AFTERNOON TEMPS SIGNIFICANTLY. REALLY DON'T
HAVE THE CONFIDENCE AT THIS TIME TO GO WITH A NON-DIURNAL TEMP
TREND...BUT WILL PASS THIS CONCERN ALONG.

BEST CHANCES OF SHOWERS/THUNDERSTORMS WILL HOLD OFF UNTIL SATURDAY
NIGHT...ESPECIALLY AFTER 06Z...AS THE MAIN UPPER LOW EJECTS INTO THE
CNTRL PLAINS. HIGH POPS WARRANTED AREAWIDE...WITH BEST RAINS LIKELY
ACROSS SE OK INTO WCNTRL AR LATE SATURDAY NIGHT INTO SUNDAY. SEVERE
THREAT CONTINUES TO LOOK MARGINAL...ALTHOUGH COULD SEE SPORADIC
SEVERE WIND/HAIL WITH THE STRONGER STORMS IN THE SERN PARTS OF THE
AREA. THE DRYLINE ASSOCIATED WITH THIS SYSTEM SHOULD PUNCH INTO WRN
AR TOWARD 18Z...WITH PRECIP ENDING DURING THE AFTERNOON.

FORECAST FOR TUESDAY INTO WEDNESDAY REMAINS PROBLEMATIC...WITH
EXPECTED STRENGTH/TIMING DIFFERENCES AMONGST THE VARIOUS MODEL
SOLUTIONS. ECMWF/UKMET IN AGREEMENT SWING A POSITIVE TILT TROF
THROUGH THE REGION LATE TUESDAY/TUESDAY NIGHT...WHILE THE GFS/GEM
OFFERS A MUCH MORE PROGRESSIVE SOLUTION. FORECAST THERMAL FIELDS ARE
A BIT WARMER THAN PREVIOUS RUNS...SO HAVE OPTED TO MENTION JUST A
RAIN/SNOW MIX TUESDAY NIGHT FOR NOW....MAINLY SOUTH OF I-40. WILL
CONTINUE TO CLOSELY MONITOR.

	AREA...FAR SOUTHEAST OKLAHOMA.
	ONSET...ONGOING.

SIGNIFICANT WINDS.
	RISK...LIMITED.
	AREA...NORTHEAST OKLAHOMA.
	ONSET...ONGOING.

DISCUSSION...
ISOLATED STRONG THUNDERSTORMS HAVE DEVELOPED ACROSS PORTIONS OF
FAR SOUTHEAST OKLAHOMA. THE ATMOSPHERE HAS BECOMING MODERATELY
UNSTABLE ACROSS THIS AREA WITH BREAKS IN THE CLOUD COVER.
A FEW OF THESE STORMS COULD BECOME SEVERE WITH THE THREAT FOR LARGE
HAIL. THE SHOWER AND THUNDERSTORM ACTIVITY WILL TAPPER OFF THIS
EVENING FROM WEST TO EAST AS MORE STABLE AIR FILTERS IN BEHIND THE
COLD FRONT.

GUSTY NORTH AND NORTHEASTERLY WINDS IN THE 20 TO NEAR 30 MPH RANGE
HAVE BEEN COMMON ACROSS WESTERN OKLAHOMA BEHIND THE FRONTAL
PASSAGE. WIND GUSTS UP AROUND 25 MPH WILL BE POSSIBLE ACROSS
NORTHEAST OKLAHOMA BEHIND THE FRONT. GUSTY WINDS SHOULD DECREASE
DURING THE EVENING HOURS AS THE FRONT EXITS OFF TO THE EAST.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
LOCAL SPOTTER ACTIVATION MAY BE NEEDED.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.
FRIDAY...NO HAZARDS.
SATURDAY...THUNDERSTORM POTENTIAL...HIGH WIND POTENTIAL.
SUNDAY...THUNDERSTORM POTENTIAL.
MONDAY...NO HAZARDS.
TUESDAY...WINTER WEATHER POTENTIAL.
WEDNESDAY...NO HAZARDS.

EXTENDED DISCUSSION...
THUNDERSTORM CHANCES INCREASE AGAIN SATURDAY AFTERNOON INTO SUNDAY
AS THE NEXT LOW PRESSURE SYSTEM MOVES THROUGH THE PLAINS. LIMITED
INSTABILITY WITH THIS SYSTEM WILL ALLOW A LIMITED THREAT OF SEVERE
WEATHER SATURDAY EVENING AND SATURDAY NIGHT.

ANOTHER UPPER LEVEL DISTURBANCE LOOKS TO MOVE ACROSS THE SOUTHERN
PLAINS DURING THE FIRST HALF OF NEXT WEEK. COLDER AIR WITH THIS
SYSTEM COULD CREATE LIGHT WINTRY PRECIPITATION AS IT MOVES THROUGH
TUESDAY NIGHT. AS OF NOW...IT APPEARS THAT ANY ACCUMULATIONS WOULD
BE ON THE LIGHT SIDE.
