DISCUSSION
ISSUED AT 122 PM CST TUE JAN 27 2026
THROUGH WEDNESDAY: NOT AS COLD AND CONTINUED DRY. LATEST VISIBLE
SATELLITE IMAGERY CLEARLY SHOWED THE SNOW/ICE ACROSS OUR DELTA
REGION. LATEST SURFACE OBSERVATIONS SHOWED TEMPERATURES ABOVE
FREEZING ACROSS THE WHOLE CWA FOR THE FIRST TIME SINCE THE WEEKEND.
THIS SHOULD LEAD TO SOME MELTING IN OUR NORTH. TEMPERATURES WILL
FALL BACK BELOW FREEZING THIS EVENING BUT NOT BOTTOM OUT AS COLD AS
THE LAST COUPLE OF NIGHTS. LATEST SURFACE ANALYSIS HAD A 1034MB HIGH
PRESSURE CENTERED OVER SOUTHERN LOUISIANA. THIS SURFACE HIGH WILL
ESSENTIALLY REMAIN IN PLACE AND WEAKEN AS A SHORTWAVE TROUGH DROPS
ACROSS THE REGION AND DRAWS A STRONGER SURFACE HIGH SOUTHEAST OVER
THE SOUTHERN PLAINS THROUGH WEDNESDAY. THESE FEATURES WILL HELP
MAINTAIN COLDER THAN NORMAL TEMPERATURES WEDNESDAY BUT AFTERNOON
HIGHS WILL TOP OUT SEVERAL DEGREES WARMER THAN THIS AFTERNOON. /22/
WEDNESDAY NIGHT THROUGH EARLY NEXT WEEK...
THE COLD PATTERN WILL PERSIST THROUGH THE REMAINDER OF THE PERIOD
AMID BROAD TROUGHING OVER EASTERN CONUS. JUST ABOUT EVERY NIGHT THIS
WEEK WILL BE SUBFREEZING FOR MUCH OF THE AREA. A SERIES OF
REINFORCING WAVES/COLD FRONTS WILL LOCK IN COLD AIR OVER THE REGION.
WHILE, THESE WAVES WILL LARGELY BE DRY, A WAVE FRIDAY HAS THE THE
POTENTIAL TO EKE OUT SOME MOISTURE. SURFACE TEMPERATURES WILL BE
WARM ENOUGH IN THE SOUTH TO SUPPORT RAIN, HOWEVER IT MAY BE COLD
ENOUGH FOR SNOW IN THE NORTH. SOUNDINGS ARE SUPPORTIVE OF A
RAIN/SNOW PROFILE WITH COLD AIR ALOFT. THIS SHOULD LIMIT FREEZING
RAIN POTENTIAL. THAT SAID, CANNOT RULE OUT BRIEF FREEZING DRIZZLE IN
AREAS WITH SUFFICIENT BOUNDARY LAYER MOISTURE AND DRY DGZ. AS THE
PROFILE COOLS, FLURRIES OR LIGHT SNOW SHOWERS WILL BE POSSIBLE.
THESE ARE NOT EXPECTED TO BE IMPACTFUL.
A RAPIDLY DEEPENING SURFACE LOW OFF THE COAST OF THE CAROLINA'S WILL
WORK TO TIGHTEN THE PRESSURE GRADIENT OVER THE AREA AND WILL BRING
BRISK NNW WINDS AROUND THE BACKSIDE IN ADVANCE OF A STRONG SURFACE
HIGH. THIS RAISES GREAT CONCERN FOR DANGEROUSLY COLD WIND CHILLS,
GENERALLY AROUND -5 - +10 DEGREES. HIGH CONFIDENCE HAS PROMPTED THE
INTRODUCTION OF AN ELEVATED GRAPHIC EARLY TO START MESSAGING THIS.
WILL CONTINUE TO MONITOR TRENDS FOR WIND GUSTS AND A SIGNIFICANT
COULD BE INTRODUCED AND AN EXTREME COLD WARNING WILL LIKELY BE
NEEDED, POSSIBLY AREAWIDE. THE COLDEST WIND CHILL VALUES ARE
EXPECTED FRIDAY NIGHT INTO SATURDAY AS WIND GUSTS PEAK AROUND 25MPH.
PRESSURE GRADIENT RELAXES WITH THE SURFACE HIGH SATURDAY NIGHT,
LIMITING WIND CHILL. ACTUAL LOW TEMPERATURES WILL LIKELY BE IN THE
TEENS AREAWIDE SATURDAY NIGHT INTO SUNDAY MORNING WITH POCKETS OF
SINGLE DIGITS IN THE NORTH. LOWS THIS WEEKEND HAVE THE POTENTIAL TO
BREAK SEVERAL RECORDS.
EARLY NEXT WEEK, A SHORTWAVE AND ASSOCIATED SURFACE LOW WILL TURN
WINDS BACK OUT OF THE SOUTH AND WILL HELP TO MODERATE TEMPERATURES
TO NEAR NORMAL. THIS WILL ALSO BRING A POSSIBILITY OF LIGHT RAIN
SHOWERS BY WEDNESDAY./SAS/
