DISCUSSION
(THIS AFTERNOON THROUGH NEXT MONDAY)
ISSUED AT 1149 AM CST TUE JAN 13 2026
WE HAD ANOTHER CHILLY START TO OUR DAY WITH MORNING LOWS IN THE
20S AND 30S. A 1025 MB HIGH PRESSURE TO OUR SOUTH, QUASI-ZONAL
FLOW ALOFT, AND ELEVATED SOUTHWEST WINDS HAS USHERED WARMER AIR
IN TODAY WITH CURRENT TEMPERATURES IN THE MID TO UPPER 50S,
WARMING INTO THE LOW TO MID 60S THIS AFTERNOON. DRY CONDITIONS
WILL PREVAIL THROUGH THE REST OF TODAY AS PERSISTENT DRY AIR
REMAINS IN PLACE.
LATE TONIGHT AND INTO EARLY TOMORROW, A PRONOUNCED PATTERN SHIFT
WILL OCCUR AS A CUT OFF UPPER-LOW PUSHES INTO THE LOWER
MISSISSIPPI VALLEY AND A POSITIVELY TILTED TROUGH DIPS DOWN OVER
THE GREAT LAKES REGION FROM SOUTHERN ONTARIO. AT THE SURFACE, AN
ATTENDANT COLD FRONT, EXTENDING ACROSS MUCH OF THE CENTRAL CONUS,
WILL ALSO BEGIN PUSHING INTO THE MID-SOUTH. THIS COLD FRONT AND
AFOREMENTIONED UPPER-LEVEL SYSTEMS WILL ALL GIVE LIFT TO
INCREASED SHOWER CHANCES (30-60%), MOVING NORTHWEST TO SOUTHEAST,
BEGINNING EARLY TOMORROW MORNING. AS WE EDGE PAST SUNSET,
RAINFALL CHANCES (60-80%) INCREASE, ESPECIALLY EAST OF THE
MISSISSIPPI RIVER. GIVEN THE TIME OF DAY THE AFOREMENTIONED FRONT
MOVES ACROSS OUR AREA, TEMPERATURES WILL LIKELY FALL THROUGHOUT
THE DAY, RESULTING IN OUR HIGH TEMPERATURES OCCURRING IN THE
MORNING HOURS. THIS FRONT WILL BE QUICKLY MOVING WITH RAIN
CHANCES DIMINISHING SHORTLY AFTER SUNSET TOMORROW. RAIN AMOUNTS
ONLY EQUATE TO UP TO A QUARTER OF AN INCH. AS DRY AIR AND STRONG
CAA WILL QUICKLY FOLLOW THIS FRONT, ALL PRECIPITATION TOMORROW
WILL FALL AS RAIN.
THE AFOREMENTIONED CAA AND A QUICK MOVING ARCTIC AIRMASS WILL
TURN OUR EYES TO COLD TEMPERATURES THURSDAY MORNING WITH MINIMUM
APPARENT TEMPERATURES IN THE TEENS AND AFTERNOON HIGHS STRUGGLING
TO BREAK OUT OF THE 30S ACROSS MUCH OF THE MID-SOUTH. FRIDAY,
THIS ARCTIC HIGH PRESSURE WILL SLIDE TO OUR EAST AND SOUTH WINDS
WILL USHER IN SLIGHTLY WARMER AIR INCREASING AFTERNOON HIGHS INTO
THE 50S. WINDS WILL BE ELEVATED WITH SOME STRONGER GUSTS, UP TO
30 MPH, FRIDAY AS THE PRESSURE GRADIENT TIGHTENS OVER THE UPPER-
MISSISSIPPI VALLEY, STRONGEST GUSTS OVER NORTHEAST ARKANSAS AND
THE MISSOURI BOOTHEEL. AS WE MOVE INTO THE WEEKEND, THE WEATHER
PATTERN BECOMES LARGELY UNSETTLED AS ENSEMBLES ARE HINTING AT A
CLOSED LOW AND UPPER-TROUGH PUSHING IN FROM CANADA AND OVER THE
MIDWEST. MOST OF THE MOISTURE DOES LOOK TO BE CAPPED OFF, NORTH
OF THE MID-SOUTH. THOUGH WE WILL CONTINUE TO MONITOR THE
EVOLUTION OF THIS SYSTEM. ONE THING WE DO KNOW IS, TEMPERATURES
WILL BE PRETTY CHILLY THIS WEEKEND AND INTO EARLY NEXT WORKWEEK
AS ANOTHER COLD AIRMASS AND ANOTHER PRETTY DECENT SWATH OF CAA
FILTERS IN. COLD WEATHER PRODUCTS MAY BE WARRANTED, ESPECIALLY
SUNDAY MORNING AS MINIMUM APPARENT TEMPERATURES FALL INTO THE
SINGLE DIGITS AND TEENS. STAY TUNED..

(00Z TAFS)
ISSUED AT 543 PM CST TUE JAN 13 2026
GUSTY WINDS WILL CONTINUE THROUGH MUCH OF THE EVENING AHEAD OF A
COLD FRONTAL PASSAGE. THE TIGHT PRESSURE GRADIENT DOES BRING SOME
WINDSHEAR CONCERNS AT 2000FT FOR A BRIEF PERIOD TONIGHT.
PRECIPITATION ONSET AT THE TERMINALS HAS BEEN DELAYED DUE TO
PERSISTENT DRY AIR AND FORECASTED LARGE DEWPOINT DEPRESSIONS.
SHOWERS SHOULD BE LIGHT IN NATURE AND RESTRICT VISIBILITIES FROM
DROPPING BEYOND MVFR.
CEILINGS WILL DIP TO MVFR WITH PRECIPITATION AND DURING FROPA.
PROBABILITIES OF IFR CEILINGS REMAIN LESS THAN 40% AT ALL
TERMINALS, BUT TUP WOULD BE THE MOST LIKELY SITE TO REACH IFR. A
QUICK REBOUND IS ANTICIPATED TO VFR BY TOMORROW AFTERNOON WITH
GUSTY NORTHWESTERLY FLOW BEHIND THE BOUNDARY.

FIRE WEATHER
ISSUED AT 1149 AM CST TUE JAN 13 2026
MINIMUM RELATIVE HUMIDITY VALUES THIS AFTERNOON WILL BE AT OR
BELOW 40% WITH SOME AREAS WEST OF THE MISSISSIPPI RIVER SEEING
VALUES LESS THAN 35%. ELEVATED 20FT WINDS, GREATER THAN 10 MPH,
WILL LIKELY LEAD TO AN ELEVATED FIRE DANGER TODAY. TOMORROW,
WETTING RAIN CHANCES INCREASE, ESPECIALLY EAST OF THE MISSISSIPPI
RIVER, AIDED BY A COLD FRONT. MOVING INTO THE LATTER HALF OF THE
WEEK, MINIMUM RELATIVE HUMIDITY WILL ONCE AGAIN FALL LESS THAN
40% WITH SOME AREAS AROUND 30%.
