Severe Thunderstorm Warning 211, NWS Tulsa, OK

EASTERN OKLAHOMA/NORTHWEST ARKANSAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OKLAHOMA
312 AM CDT FRI MAY 16 2003

STRONG STORMS WITH VERY HEAVY RAINFALL AND POSSIBLY STRONG WINDS AND
HAIL ARE BEARING DOWN ON THE FORECAST AREA AT THIS TIME.  EXPECT A
WIDESPREAD RAINFALL THIS MORNING PRIMING THE AREA FOR POSSIBLE
FLOODING PROBLEMS LATER TODAY WHEN ADDITIONAL STRONG STORMS FORM.

MAIN DRIVING FEATURE IS A STRONG UPPER LOW WHICH WILL MOVE INTO THE
AREA TONIGHT.  PRECIPITAL WATERS AND INSTABILITY ARE BOTH QUITE HIGH
SO THE RISK OF HEAVY RAINFALL AND SEVERE WEATHER IS HIGH AS WELL.
IN ADDITION...THE ETA QPF IS QUITE ROBUST AS IS HPCS DAY 1 QPF.

THE  UPPER LOW HANGS IN THE VICINITY TOMORROW SO RAIN CANNOT BE
RULED OUT.  TOMORROW SHOULD AT LEAST BE A CLOUDY AND DREARY DAY.
HAVE SOME TEMPERATURE ISSUES THE NEXT FEW DAYS.  DO NOT SEE THE DEW
POINTS IN THE 60S ACROSS THE AREA GETTING SWEPT AWAY ANY TIME SOON.
THUS...LOWS WOULD HAVE A TOUGH TIME GETTING INTO THE 50S AS THE GFS
MOS SUGGESTS.  WITH WARMER LOWS WILL ALSO HAVE WARMER DAY TIME TEMPS
ALTHOUGH DO NOT BELIEVE THERE WILL BE MUCH OF A DIURNAL RANGE.

SOME OF THE MOISTURE WILL LIKELY GET SWEPT OUT OF THE AREA TO MAKE
SUNDAY AND MONDAY RATHER PLEASANT AND MAINLY DRY DAYS.  THE NEXT
DECENT RAIN CHANCES WILL BE MONDAY NIGHT AND TUESDAY WITH A COLD
FRONT.
