..NEW SHORT TERM, LONG TERM, MARINE
SHORT TERM
(TONIGHT THROUGH FRIDAY NIGHT)
ISSUED AT 156 PM CST THU JAN 16 2025
HIGH PRESSURE WILL LEAD TO VERY PLEASANT WEATHER TO END THE WORK
WEEK WITH LIGHT TO OCCASIONALLY MODERATE EASTERLY FLOW.
TEMPERATURES FOR TONIGHT WILL BE IN THE 40S. WINDS WILL SHIFT TO
THE SOUTH, BRINGING WARM AIR INTO THE REGION FOR FRIDAY WITH
HIGHS IN THE 70S EXPECTED ACROSS THE AREA AND FRIDAY NIGHT LOWS IN
THE 50S.
LONG TERM
(SATURDAY THROUGH NEXT WEDNESDAY)
ISSUED AT 156 PM CST THU JAN 16 2025
KEY MESSAGES:
- WIDESPREAD FREEZING TEMPERATURES EXPECTED THE FIRST PART OF NEXT
WEEK
- LOW TO MEDIUM (25-45%) CHANCE OF WINTRY PRECIPITATION MONDAY NIGHT
THROUGH TUESDAY, MAINLY FREEZING RAIN.
A COLD FRONT SATURDAY WILL ALLOW FOR INFILTRATION OF A COLD ARCTIC
AIR MASS INTO SOUTH TEXAS INTO EARLY NEXT WEEK. CONFIDENCE IS STILL
LOW AS FORECAST MODELS HAVE STRUGGLED WITH THIS SYSTEM BUT IS SLOWLY
INCREASING. CONFIDENCE SHOULD IMPROVE FURTHER ONCE THE NAM IS
AVAILABLE IN FUTURE RUNS. REGARDLESS, WE HAVE ALREADY INTRODUCED
SOME PROBABILITIES FOR A LIMITED AMOUNT OF FROZEN PRECIPITATION OR A
WINTRY MIX MONDAY NIGHT INTO TUESDAY.
BUT FIRST LOOKING AT THIS WEEKEND, AFTER FROPA EARLY SATURDAY
MORNING WINDS SHIFT TO THE NORTH ACCOMPANIED BY DRIER CONDITIONS.
THE COLDER AIR WILL SLOWLY SLIDE INTO THE REGION OVER THE WEEKEND
INTO EARLY NEXT WEEK. THE OVERLAPPING OF MOISTURE ADVECTION WITH
FREEZING TEMPERATURES IS WHAT HAS BEEN SO CHALLENGING WITH THIS
SYSTEM. FREEZING RAIN IS STILL THE MAIN THREAT BUT SLEET AND SNOW
REMAIN POSSIBLE. DETERMINISTIC MODEL (JUST ONE MODEL RUN) SOUNDINGS
FOR TUESDAY HAVE TEMPERATURES BORDERING THE FREEZING LEVEL UP
THROUGH 700 MB WITH A MOIST PROFILE, WHICH WOULD BE SHORT OF THE
DENDRITIC GROWTH ZONE (DGZ) ALONG THE COASTAL BEND BUT SIGNIFICANTLY
CLOSER TO THE DGZ ACROSS THE BRUSH COUNTRY AND VICTORIA CROSSROADS,
WHICH WOULD BE THE LAYER OF THE ATMOSPHERE WHERE SNOW DEVELOPS.
HOWEVER, ENSEMBLE MODEL RUNS (THOUSANDS OF MODEL RUNS) CONTINUE TO
SHOW ALL FORMS OF WINTER PRECIPITATION STILL IN PLAY ACROSS ALL OF
SOUTH TEXAS, ALBEIT FREEZING RAIN STILL LOOKING THE BEST.
AFTER HIGH TEMPERATURES IN THE UPPER 60S TO MID 70S SATURDAY, HIGHS
SUNDAY START TO DECREASE WITH THE LOW POINT ON TUESDAY WITH LOW TO
MID 40S. LOWS AHEAD DURING THE OVERNIGHT PERIODS REMAIN IN THE 30S
FOR MUCH OF THE WEEK. AFTER TUESDAY THE REMAINDER OF THE WEEK LOOKS
TO BE MAINLY DRY AND TEMPERATURES REBOUND INTO THE 50-60S FOR HIGHS
AND MID 30S TO 40S FOR LOWS THUS ENDING THE THREAT FOR WINTER PRECIP
FOR THIS FORECAST PERIOD.
PLEASE REMEMBER THIS IS A LONG WAYS OUT AND THINGS CAN CHANGE:
MODELS MAY CONTINUE TO TREND WARMER, TIMING OF THE MOISTURE, LIFT,
AND FREEZING TEMPERATURES MAY NOT MESH LEAVING US WITH JUST RAIN,
ETC. THE BEST COURSE OF ACTION IS TO PREPARE FOR COLD WEATHER.
PROTECT YOUR PEOPLE (NEIGHBORS, ELDERLY FAMILY MEMBERS...), PETS
(INCLUDING LIVESTOCK), PLANTS, AND PIPES.
