FOUR STATE AREA WEATHER SUMMARY 

NATIONAL WEATHER SERVICE SHREVEPORT LA

400 AM CDT WED MAY 2 2001



A PARTLY TO MOSTLY CLOUDY SKY WAS OBSERVED ACROSS THE WESTERN AND 

CENTRAL PORTIONS OF THE FOUR STATE REGION THIS MORNING...AS LOW 

CLOUDINESS THAT DEVELOPED ALONG THE TEXAS GULF COAST...SPREAD 

NORTHWARD OVERNIGHT.  HOWEVER...A MOSTLY CLEAR SKY PREVAILED 

ELSEWHERE.  EARLY MORNING TEMPERATURES RANGED FROM THE LOWER TO 

MIDDLE 60S.



AFTER SOME MORNING LOW CLOUDINESS ACROSS PORTIONS OF THE REGION THIS 

MORNING...LOOK FOR A MOSTLY SUNNY TO PARTLY CLOUDY SKY ACROSS MUCH 

OF THE FOUR STATE REGION TODAY...AS A RIDGE OF HIGH PRESSURE ALOFT 

BUILDS IN OVER MUCH OF THE DEEP SOUTH.  THIS RIDGE IS IN RESPONSE TO 

AN UPPER TROUGH OF LOW PRESSURE THAT WILL DIG INTO THE GREAT BASIN 

LATER THIS EVENING...AND THE DEPARTING UPPER LOW OVER THE NORTHERN 

GULF.  THE UPPER TROUGH OVER THE GREAT BASIN WILL STALL OUT AND 

SLOWLY INTENSIFY...RESULTING IN CONTINUED UNSETTLED WEATHER ACROSS 

THE MIDWEST AND CENTRAL PLAINS...AS ITS ASSOCIATED COLD FRONT WILL 

STALL OUT AS WELL.  THE UPPER RIDGE WILL WEAKEN ON THURSDAY...AND 

SHOWERS AND THUNDERSTORMS WILL DEVELOP A BIT FURTHER SOUTH ALONG THE 

FRONTAL BOUNDARY...INTO PORTIONS OF OKLAHOMA AND WEST TEXAS.  UPPER 

LEVEL MOISTURE FROM THIS SYSTEM WILL ENTER THE REGION THURSDAY 

EVENING...AND REMAIN IN PLACE DURING THE WEEKEND.  THIS SYSTEM WILL 

FINALLY LIFT OUT INTO THE PLAINS SATURDAY...AND UPPER LEVEL IMPULSES 

ASSOCIATED WITH IT MAY TRIGGER A FEW SHOWERS AND THUNDERSTORMS 

ACROSS THE AREA DURING THE UPCOMING WEEKEND.  SOUTHERLY WINDS WILL 

INCREASE TODAY AND AGAIN ON THURSDAY...IN RESPONSE TO A DEVELOPING 

SURFACE LOW OVER EASTERN COLORADO.  THIS WILL ALLOW LOW LEVEL MOISTURE

TO CONTINUE INCREASING ACROSS THE AREA FROM THE GULF...RESULTING IN

MILDER OVERNIGHT TEMPERATURES...HIGHER HUMIDITIES...AND A PARTLY

CLOUDY SKY.



EARLY MORNING LOW TEMPERATURES THURSDAY AND FRIDAY MORNINGS...WILL 

CONTINUE IN THE LOWER TO MIDDLE 60S.  AFTERNOON HIGH TEMPERATURES 

TODAY AND THURSDAY...WILL RANGE FROM THE LOWER TO MIDDLE 80S.
