AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
1155 PM CST WED FEB 4 2026
..NEW DISCUSSION, MARINE
KEY MESSAGES
- ONE MORE CHILLY NIGHT IS AHEAD TONIGHT, WITH LOWS IN THE 30S FOR
ALL BUT THE HOUSTON CORE AND IMMEDIATE COAST. ISOLATED SPOTS
REACHING OR BRIEFLY DIPPING BELOW THE FREEZING MARK AROUND DAWN
SHOULD BE LIMITED TO LOCATIONS NORTH OF HUNTSVILLE.
- THURSDAY WILL MARK THE BEGINNING OF A WARMING TREND, THOUGH THIS
FIRST WARMER DAY WILL ONLY SEE TEMPERATURES SLIGHTLY HIGHER THAN
WEDNESDAY. MORE MARKED INCREASES IN TEMPS WILL KICK IN THROUGH
THE WEEKEND AND INTO THE FIRST HALF OF NEXT WEEK.
- GUSTY WINDS ON COASTAL WATERS WILL HANG WITH US THROUGH MUCH OF
THE NIGHT BEFORE FINALLY DIMINISHING BELOW THRESHOLDS MORE
HAZARDOUS TO SMALL CRAFT. NAVIGATION LOOKS TO REMAIN DIFFICULT
ON THE BAYS, PARTICULARLY THE UPPER PORTIONS OF GALVESTON BAY,
DUE TO LOW WATER THROUGH AT LEAST FRIDAY MORNING'S LOW TIDE
CYCLE.
DISCUSSION
ISSUED AT 1155 PM CST WED FEB 4 2026
AFTER TUESDAY'S COLD FRONT, WE DID GET CHILLY OVERNIGHT, BUT MUCH
MORE OF THE TYPE OF WINTER TYPE TYPICAL OF WINTER IN SOUTHEAST
TEXAS, AND WARMER THAN THE COLD WE HAD TO CLOSE OUT JANUARY. THAT
SEASONABLY COOL VIBE CARRIED THROUGH THE DAY, AND SHOULD BE THE
EXPECTATION FOR THURSDAY AS WELL. IN FACT, THE FORECAST IS FOR
TEMPS TO GET COLDER BY DAWN ON THURSDAY MORNING THAN THE PREVIOUS
NIGHT, WITH ALL BUT THE CORE OF HOUSTON'S HEAT ISLAND AND THE
IMMEDIATE COAST LOOKING TO FALL INTO THE 30S. STILL, WE DON'T LOOK
TO FALL TOO TERRIBLY FAR BELOW AVERAGE, AS DESPITE THE SCARY SOUND
OF 30S AREA-WIDE, ONLY ISOLATED SPOTS NORTH OF HUNTSVILLE ARE
EXPECTED TO REACH THE FREEZING MARK.
CONTINUED SUN AND FAIR WEATHER WILL HELP THURSDAY AFTERNOON, AS
WILL BUILDING HIGH PRESSURE. THOUGH, WITH THE CHILLY START TO THE
DAY, FORECAST HIGHS ARE ONLY A SCOCH HIGHER THURSDAY THAN
WEDNESDAY'S OBSERVED VALUES. THE MORE SIGNIFICANT PART OF THE
WARMING TREND WILL KICK IN AFTER THAT, AND ESPECIALLY ONCE ONSHORE
FLOW BECOMES FULLY ESTABLISHED SATURDAY NIGHT. FAIR WEATHER,
STACKED RIDGING, PLENTY OF SUN, AND ONSHORE FLOW KEEPING UP THE
OVERNIGHT TEMPERATURE FLOW IS A GOOD RECIPE FOR SENDING
TEMPERATURES WELL ABOVE SEASONAL AVERAGES.
HOW HIGH ARE WE TALKING? WELL, SPEAKING DETERMINISTICALLY, I DO
HAVE HIGHS IN THE LOWER 80S TRYING TO SNEAK IN EARLY NEXT WEEK.
OVERNIGHT, FORECAST LOWS ARE ABOUT AS CLOSE TO AVERAGE HIGHS FOR
THIS TIME OF YEAR THAN AVERAGE LOWS...OR CLOSER! OF COURSE, AS
MUCH AS I'D LIKE MY SINGLE VALUE NUMBERS TO BE PERFECT, I KNOW
THINGS WON'T *EXACTLY* TURN OUT THAT WAY, JUST MOSTLY TURN OUT
THAT WAY. LET'S FUZZ THINGS UP A BIT WHILE WE EXPLORE THAT A BIT.
LOOKING AT THE NAEFS AND EURO ENSEMBLE MEANS, WE SEE THE POTENTIAL
FOR UPPER-END TEMPERATURES EMERGING FROM FRIDAY ONWARD. WHILE NOT
WIDESPREAD ACROSS THE AREA, MEAN 850 TEMPS ABOVE THE 90TH
PERCENTILE EMERGE, AS DO 500 MB HEIGHTS. IN FACT, THIS TREND IS
PROBABLY EVEN CLEARER IN MID-LEVEL HEIGHTS, WITH LARGE SWATHS OF
THE AREA GETTING ABOVE THE 97TH PERCENTILE (NAEFS) OR EVEN THE
99TH PERCENTILE (EURO ENSEMBLE) WEDNESDAY. ALL IN ALL, THIS
PAINTS A PRETTY HIGH CONFIDENCE PICTURE OF STRONG RIDGING ALOFT,
HELPING DRIVE POTENTIAL FOR WELL ABOVE-AVERAGE TEMPERATURES.
THIS IS BACKED UP IN THE EURO ENSEMBLE'S EXTREME FORECAST INDEX,
WHERE WE CONTINUE TO GET SUGGESTIVE HINTS AT SOME POTENTIAL FOR
EXTREME HIGH TEMPERATURES. IMPORTANT TO NOTE, OF COURSE, THAT
"EXTREME" HERE MEANS RELATIVE TO EARLY FEBRUARY, NOT FOR SOUTHEAST
TEXAS IN GENERAL. A DAY THAT PARTICULARLY STANDS OUT TO ME IS
WEDNESDAY. THAT'S WHEN WE GET THOSE REAL HIGH PERCENTILE 500 MB
HEIGHTS, AND THE EFI STARTS TO SHOW AREAS IN OUR WEST EXCEEDING
0.7 - A NOTICEABLE BOOST TO CONFIDENCE OVER THE SPECKLES OF STUFF
OVER 0.5 WE DISCUSSED YESTERDAY.
ULTIMATELY, THIS HAS ME QUITE COMFORTABLE WITH NOT ONLY FOLLOWING
THE DETERMINISTIC NBM'S TREND OF TEMPERATURES, BUT IN GOING AHEAD
AND MODESTLY HEDGING WARMER THAN IT BY REPLACING IT WITH THE NBM
50TH PERCENTILE WHERE THOSE MEDIAN TEMPS ARE HIGHER THAN THE
DETERMINISTIC. ON WEDNESDAY, SHOULD CONFIDENCE CONTINUE TO BUILD,
WE MAY NEED TO EVEN EXPLORE HIGHER IN THE PROBABILISTIC
DISTRIBUTION!
NOW, WHILE MOST OF THE TALK IS ABOUT TEMPERATURES, WE'RE NOT
NECESSARILY LOOKING ENTIRELY FOR FAIR WEATHER IN THIS FORECAST
PERIOD. TUESDAY LOOKS INTERESTING AS A QUICK, BUT POTENT UPPER
TROUGH SHOOTS THROUGH THE REGION, GIVING US A CHANCE FOR A QUICK
HITTER SHOT OF RAIN. BY HOW MUCH I'VE TALKED UP WEDNESDAY, YOU CAN
TELL IT'S NOT GOING TO BE A PROLONGED IMPACT, BUT IT LOOKS LIKE A
SOLID ENOUGH SHORTWAVE (IT HAS TO BE, TO BRIEFLY SUBDUE 90TH
PERCENTILE PLUS MID-LEVEL RIDGING!) TO BRING US A ROUND OF
SHOWERS. AND...IF ALL THE INGREDIENTS LINE UP RIGHT, MAYBE EVEN
SOME THUNDERSTORMS WITH AN ISOLATED STRONGER TO SEVERE STORM. THAT
WOULD REALLY BE TRENDING TOWARDS MORE OF A WORST CASE SCENARIO,
FORTUNATELY, NOT THE MOST LIKELY ONE. AM I TRYING TO JINX THAT
SCENARIO OUT OF EXISTENCE BY BRINGING IT UP 6 DAYS OUT? MAYBE! BUT
ALSO, IT'S NOT SOMETHING I CAN COMPLETELY DISMISS AT THIS RANGE.
