227 PM CDT SUN SEP 16 2001

LATEST MODEL RUN CONTINUES TO SHOW A WEAK FLOW OVER AREA. SEVERAL
BOUNDARYS LEFT OVER FROM THIS MORNINGS CONVECTION. THIS TO BE AREA
OF FOCUS FOR CONVECTION THIS EVENING. A COUPLE OF WEAK DISTURBANCES
ALSO TO MOVE THROUGH THE AREA. ONE DISTURBANCE MOVING EAST ACROSS
NEW MEXICO TOWARD THE SOUTHERN PLAINS AT THIS TIME. AFTER LOOKING AT
LATEST SATELLITE DATA...BELIEVE BULK OF ENERGY TO STAY ACROSS
NORTHERN AREAS OF THE FA. ANOTHER WEAK DISTURBANCE IS NOW MOVING
EAST ACROSS OKLAHOMA...REMNANTS OF THIS MORNINGS CONVECTION. THE
DISTURBANCE OVER NEW MEXICO WILL AID DEVELOPMENT OF CONVECTION THIS
EVENING AS AIRMASS REMAINS RELATIVELY UNSTABLE.

NEXT UP...MODELS INDICATE A FRONTAL BOUNDARY TO APPROACH REGION LATE
MONDAY NIGHT/EARLY TUESDAY. WILL HAVE GOOD WAA AHEAD OF BOUNDARY AND
40KT LOW LEVEL JET OVER FA AS INDICATED BY ETA MONDAY EVENING. THINK
BEST CHANCE OF RAIN ALONG EAST-WEST BOUNDARY. WITH DEEP MOISTURE OVER
AREA COULD SEE SOME LOCALLY HEAVY RAIN AS UPPER FLOW TO REMAIN VERY
WEAK. SO ANY STORMS THAT DEVELOP WILL BE SLOW MOVERS AND ALSO TO
HAVE POTENTIAL FOR STRONG DOWNBURST WINDS...AS INDICATED BY MODEL
SOUNDINGS.

WEDNESDAY/THURSDAY APPEAR PARTLY CLOUDY...THEN MODELS SHOW ANOTHER
DISTURBANCE TO APPROACH NORTHEAST SECTIONS FRIDAY. WILL MENTION
CHANCE OF THUNDERSTORMS FOR NORTHEAST FRIDAY AND STAY DRY ELSEWHERE
FOR NOW. INTO THE WEEKEND MODEL DATA INDICATES ANOTHER FRONT TO
APPROACH THE REGION LATE IN THE PERIOD. THANKS AMA/MAF FOR COORD.
