AREA FORECAST DISCUSSION...CORRECTED GRAMMAR IN 2ND PARAGRAPH
NATIONAL WEATHER SERVICE SAN ANGELO TX
1030 AM CDT SAT JUN 21 1997

AREA OF RAIN ASSOCIATED WITH UPPER LEVEL LOW OVER SOUTH TEXAS HAS
BUILT BACK NORTHWARD TO REACH THE NORTHWEST HILL COUNTRY...SOUTHERN
HEARTLAND...AND EVEN INTO CONCHO COUNTY. MOST OF THIS RAIN WAS QUITE
LIGHT...EXCEPT OCCASIONAL MODERATE RAIN HAS REACHED SOUTHERN
PORTIONS OF KIMBLE AND MASON COUNTIES. HIGH CLOUDS ON THE PERIPHERY
OF THE UPPER LOW BISECTED OUR COUNTY WARNING AREA WITH AREAS
SOUTH OF A BALLINGER TO SAN ANGELO TO BARNHART LINE MOSTLY CLOUDY
WHILE NORTHWEST AREAS WERE MOSTLY SUNNY. WITH OUR WEATHER STATION ON
THE SOUTH SIDE OF THE CITY...WE ARE UNDER THE CLOUDS AND AS THE ETA
BEGINS TO DRIFT THE UPPER LOW TO THE NORTHWEST BY THIS EVENING...IT
LOOKS LIKE MOSTLY CLOUDY SKIES ARE HERE TO STAY THROUGH THIS
AFTERNOON AND I WILL THEREFORE LOWER THE SAN ANGELO HIGHS TO BETWEEN
85 AND 90 DEGREES. OUR SOUTHEAST COUNTIES WILL STRUGGLE TO REACH 80
WITH THICKER CLOUD COVER AND OCCASIONAL RAIN.

DEW POINTS ARE SEVERAL DEGREES LOWER TODAY WHICH HAS RESULTED IN
MUCH LESS INSTABILITY. DRYLINE APPEARS TO BE FARTHER WEST
TODAY...MAINLY IN EASTERN NEW MEXICO...WITH THE DEW POINT GRADIENT
WEAKER AS WELL. CAP IS STILL STRONG AND THE UPPER LEVEL DYNAMICS
THAT HELPED STORMS SURVIVE INTO THE WESTERN BIG COUNTRY YESTERDAY
WILL NOT BE PRESENT TODAY...SO I EXPECT THE DIURNAL MOUNTAIN SHOWER
ACTIVITY TO REMAIN CONFINED TO THOSE MOUNTAIN AREAS THIS AFTERNOON
AND EVENING. FOR WEST CENTRAL TEXAS...IT APPEARS THAT THE MAIN
WEATHER MAKER WILL BE THE UPPER LOW IN SOUTH CENTRAL TEXAS. I WILL
LEAVE THE RAIN CHANCES IN DUE TO THE EFFECTS OF THIS UPPER LOWV.

LOW LEVEL WINDS ARE NOT IMPRESSIVE ON THE KDYX PROFILER AND SURFACE
PRESSURE GRADIENT IS NOT AS TIGHT AS IT WAS YESTERDAY. I WILL LOWER
THE BIG COUNTRY AND HEARTLAND WINDS TO BELOW LAKE CAUTION CRITERIA.
