AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN ANGELO TX
141 AM CDT TUE MAY 26 1998

LITTLE TIME TO TALK...WITH WARNINGS STILL ONGOING THIS EARLY
MORNING. COMBINATION OF UPPER LOW AND SURFACE FRONT VERY EFFECTIVE
IN BREAKING THROUGH THE CAP LATE MONDAY AFTERNOON AND EVENING...
THEN EFFECTIVELY UTILIZING THE CAPES OF 3000 TO 4000. APPEARS THE
UPPER LOW STILL MOVING OFF TO THE NORTHEAST...WHICH SHOULD LEAVE
LITTLE IN THE WAY OF UPPER SUPPORT FOR CONVECTIVE ACTIVITY FOR LATER
TODAY. STILL... WITH THE 00Z ETA FORECASTING CAPES OF 3500 BY 18Z...
AND WITH THE CAP LIKELY WEAKENED TO A GREAT EXTENT...AND WITH
BOUNDARIES FROM THIS MORNINGS CONVECTION STILL IN THE AREA...SEEMS
PRUDENT TO LEAVE A CHANCE OF STORMS IN THE FORECAST FOR THIS
AFTERNOON AND EVENING.

WITHOUT THE MID AND HIGH LEVEL MOISTURE THAT HAS PLAGUED THE AREA
THE LAST SEVERAL DAYS...THINK THE FWC GUIDANCE MAY BE A LITTLE LOW.
WILL LEAN MORE TOWARD THE ETA FORECAST 2 METER TEMPERATURES FOR
HIGHS.
