.PREV DISCUSSION... /ISSUED 222 PM CDT SUN AUG 2 2015/

SHORT TERM (TONIGHT THROUGH MONDAY NIGHT)...
LOWER TO UPPER LEVEL RIDGING CONTINUES OVER SOUTH CENTRAL TEXAS
TONIGHT THROUGH MONDAY NIGHT. MOISTURE LEVELS REMAIN ELEVATED OVER
THE EDWARDS PLATEAU FROM THE AREA OF DEEPER MOISTURE THAT MOVED
OVER OUR AREA ON FRIDAY AND SATURDAY. NO RAIN EXPECTED AS THE
LOWEST LEVELS ARE TOO DRY. THIS ELEVATED MOISTURE ERODES
OVERNIGHT LEAVING BELOW SEASONAL NORMAL LEVELS. EXPECT DEWPOINTS
TO MIX OUT ON MONDAY WITH ONE MORE DAY OF HEAT INDEX VALUES CLOSE
TO ACTUAL TEMPERATURES. MID LEVEL SHEAR AXIS CURRENTLY OVER THE
NORTHWESTERN GULF OF MEXICO MOVES ONSHORE LATE MONDAY BRINGING
ELEVATED MOISTURE LEVELS WITH HIGHER DEWPOINTS TO AREAS NEAR THE
COASTAL PLAINS MONDAY NIGHT.

LONG TERM (TUESDAY THROUGH SUNDAY)...
THE MID LEVEL SHEAR AXIS MOVES ACROSS SOUTHERN TEXAS ON TUESDAY
BRINGING ELEVATED MOISTURE LEVELS OVER SOUTH CENTRAL TEXAS. THE
INCREASED MOISTURE WILL NOT ALLOW FOR AS MUCH MIXING OF DEWPOINTS
MAKING HEAT INDEX VALUES WARMER. SHEAR AXIS DISSIPATES WEDNESDAY
AS THE MID AND UPPER LEVEL RIDGE STRENGTHENS. DRYING TAKES PLACE
IN THE MID LEVELS TAKING MOISTURE LEVELS BELOW NORMAL. HOWEVER...
LOWER LEVEL MOISTURE WITH HIGHER DEWPOINTS REMAINS THROUGH NEXT
WEEKEND DUE TO A STRONGER LOWER LEVEL FLOW OFF THE GULF OF MEXICO.
DAYTIME HEATING WILL NOT BE AS EFFICIENT IN MIXING OF THE
DEWPOINTS KEEPING HEAT INDEX VALUES ELEVATED. HEAT ADVISORIES AND
SPECIAL WEATHER STATEMENTS MAY BE NEEDED FOR LATER THIS WEEK INTO
NEXT WEEKEND TO ADDRESS THIS POSSIBILITY. CANNOT RULE OUT A SHOWER
OR TWO ALONG THE SEABREEZE TUESDAY AFTERNOON DUE TO THE ELEVATED
MOISTURE LEVELS. OTHERWISE...STRONG SUBSIDENCE AND BELOW NORMAL
MOISTURE LEVELS KEEP RAIN OUT OF THE FORECAST. MANY SPOTS WILL
ADD TO THEIR TOTALS FOR 100 DEGREE HIGH TEMPERATURES IN THE NEXT
SEVERAL DAYS.
