..NEW SHORT TERM, LONG TERM
SHORT TERM
(TODAY THROUGH TUESDAY)
ISSUED AT 155 AM CDT MON JUN 16 2025
KEY MESSAGES:
- LOW CHANCES OF RAIN EAST TODAY
- SEASONABLE TEMPERATURES WITH ELEVATED HEAT INDEX VALUES
A FEW VERY LIGHT SHOWERS ARE NOTED DROPPING SOUTH. HOWEVER, THEY
SHOULD DISSIPATE BY SUNRISE. SUBTROPICAL RIDGING BUILDS OVER OUR
AREA IN THE SHORT TERM. HEATING AND THE SEABREEZE SHOULD GENERATE
ISOLATED SHOWERS AND THUNDERSTORMS NEAR THE COASTAL PLAINS TODAY
WHERE AN MCV IS NOTED. A SHOWER OR THUNDERSTORM OR TWO MAY BE ABLE
TO MAKE IT TO THE I-35 CORRIDOR BY EVENING. CANNOT RULE OUT GUSTY
WINDS AND HEAVY DOWNPOURS. OTHERWISE, STRENGTHENING SUBSIDENCE AND
DRYING WITH THE RIDGE WILL OVERCOME ANY FORCING TO KEEP RAIN CHANCES
OUT OF THE FORECAST. HOWEVER, CANNOT RULE OUT A SHOWER OR TWO ON
TUESDAY. EVAPOTRANSPIRATION FROM MOIST SOILS AND VEGETATION DUE TO
RECENT RAINS MAINTAINS NEAR AVERAGE TEMPERATURES AND MILDLY ELEVATED
AFTERNOON HEAT INDEX VALUES.
LONG TERM
(TUESDAY NIGHT THROUGH SUNDAY)
ISSUED AT 155 AM CDT MON JUN 16 2025
KEY MESSAGES:
- DRY WEATHER WITH NEAR NORMAL TEMPERATURES UNTIL MID-WEEK.
- THUNDERSTORM CHANCES WILL RETURN FOR THE LATTER PART OF THE WEEK.
A MID TO UPPER LEVEL RIDGE WILL OVER WEST TX. SUBSIDENT FLOW AROUND
THIS RIDGE WILL SUPPRESS MOST CONVECTION WEDNESDAY. WEDNESDAY HIGH
TEMPERATURES WILL BE CLOSE TO NORMAL. HOWEVER, SOUTHEASTERLY LOW
LEVEL FLOW WILL KEEP DEWPOINTS IN THE UPPER 60S AND LOWER 70S MAKING
HEAT INDICES 100 TO 105. THURSDAY AN INVERTED TROUGH WILL MOVE INTO
TX FROM THE GULF WEAKENING THE UPPER RIDGE. THIS SHOULD ALLOW
AFTERNOON CONVECTION TO MOVE IN FROM THE COAST ACROSS THE COASTAL
PLAINS AND INTO THE HILL COUNTRY. THIS UNSETTLED PATTERN WILL
CONTINUE EACH AFTERNOON THROUGH SUNDAY. AT THIS TIME ANY CONVECTION
LOOKS ORDINARY WITH ONLY ISOLATED MODERATE RAINFALL, BUT GIVEN THE
TIME OF YEAR AN OCCASIONAL STRONG STORM ISN'T OUT OF THE QUESTION.
