Area forecast discussion, May 31, 2:16 PM CDT, 3 hours 35 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
145 PM CDT THU MAY 31 2001

FIRST MAJOR FEATURE...H5 LOW OVER IOWA MOVING SLOWLY NORTHEAST WITH
A SHORTWAVE TROUGH THAT EXTENDS SSW THROUGH THE LOWER PLAINS. 2 VORT
FEATURES AHEAD OF THE TROUGH...ONE LOCATED IN THE MEMPHIS AREA AND
THE SECOND ...LESS DEFINED CENTER...IS LOCATED OVER SOUTH CENTRAL
TEXAS. THE CONVECTION OVER WEST TENNESSEE APPEARS TO BE ASSOCIATED
WITH THE VORT CENTER IN THE MEMPHIS AREA.

THE SECOND MAJOR FEATURE...WELL DEFINED H5 LOW OVER
SASKATCHEWAN-MANITOBA BORDER DROPPING SOUTHEASTWARD. MOVEMENT TO THE
SOUTHEAST SHOULD INCREASE AS THE IOWA LOW CONTINUES TO MOVE
NORTHEAST.

AT THE SURFACE...SURFACE LOW IS LOCATED JUST NORTHWEST OF ST LOUIS
MOVING EASTWARD AT 15 KT. A WARM FRONT EXTENDS FROM THE LOW EAST-SOUTHEAST
INTO EASTERN KENTUCKY. THE ASSOCIATED COLD FRONT EXTENDS SOUTHWESTWARD
THROUGH THE LOWER PLAINS INTO NORTH TEXAS.

MODEL PUSH THE SURFACE LOW NORTHEASTWARD INTO THE GREAT LAKES DRAGGING
THE COLD FRONT THROUGH THE MIDSTATE LATER TONIGHT AND EARLY FRIDAY
MORNING. AS THE SASKATCHEWAN LOW DROPS OUT OF CANADA A SECOND FRONT
MOVES TOWARD THE MIDSTATE ON SATURDAY WITH WINDS TURNING BACK TO THE
NORTHWEST BY SATURDAY EVENING. ONLY A BRIEF RESPITE AS ANOTHER SYSTEM
MOVES OUT OF THE PLAINS SUNDAY AND MONDAY.

FWC POPS AND TEMPS LOOK VERY REASONABLE. SELS OUTLOOKED A SLIGHT CHANCE
OF SEVERE. ORIGINALLY THOUGH THAT THIS MIGHT HAPPEN TODAY...BUT...
MORNING CLOUDINESS HAS HELD DOWN TEMPS AND IT LOOKS LIKE WE WONT
DESTABILIZE ENOUGH THIS AFTERNOON...AND...THE WIND PROFILE IS NOT
REALLY CONDUCIVE TO SEVERE. AS THE FRONT APPROACHES TONIGHT...THE WIND
PROFILE SHOULD IMPROVE AND THERE IS THE POSSIBILITY OF ISOLATED SEVERE
IN THE PRE-FRONTAL CONVECTION. MODELS ARE ONLY PREDICTING ABOUT 20-30KT
OF 0-3 KM SHEAR OVERNIGHT. THUS...I DONT THINK THAT THIS IS ENOUGH OF A
POSSIBILITY TO MENTION IT IN THE ZONE PACKAGE.
