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.
