DISCUSSION

60F DEW POINTS HAVE ENTERED THE SOUTHERN REACHES OF THE FA. THE
WAA GAME IS STRONG, AND IT NEEDS TO BE, BECAUSE TIME/HEIGHT
CROSS SECTIONS SUGGEST CONTINUED CLOUD COVER INHIBITING THE
TEMPERATURE CLIMB. THIS WILL RETARD THE ALREADY COMPROMISED
INSTABILITY/PARCEL BUOYANCY FORECAST, WITH MUCAPE MODELED TO
PEAK SOMEWHERE IN THE 200-400 JOULES RANGE OVER SEMO THIS
EVENING, A SLIGHT DOWNTICK FROM EARLIER MODELING. IT'LL BE A
SHORT SLIVER OF TIME BETWEEN 00-06Z THAT EXISTS IN COINCIDENCE
WITH THE HIGH SHEAR ENVIRON FOR OUR SEVERE WX POTENTIAL...WE'LL
SEE HOW IT PLAYS OUT AS THERE IS SOME CONCERN WITH THE PARALLEL
ORIENTATION OF THE SHEAR FIELD WRT CONVECTIVE LINE DEVELOPMENT.
NEVERTHELESS, H8 WINDS TO 60+KTS WON'T TAKE MUCH TO DRAW DOWN,
OFFERING "SEVERE" SHOWER POTENTIAL EVEN FOR DAMAGING WIND GUSTS.
OUTSIDE OF STORMS, EXPECT GRADIENT WINDS TO CRANK UP THIS
AFTERNOON/EVENING TOO, SHY OF ADVISORY CRITERIA BUT BREEZY
NONETHELESS.
SOME 12Z DATA SUGGESTS THE FRIDAY CHANCE IS OVERDONE, AND
CHANCES INCLUDING SEVERE STORM CHANCES SHOULD WASH AFTER FROPA
LATE TONIGHT-EARLY FRIDAY. NEVERTHELESS WE REMAIN IN A MARGINAL
RISK IN OUR SOUTH/EAST, AT LEAST UNTIL THE BLENDED/ENSEMBLE
MODELING CATCHES UP. AFTER THE SYSTEM FINALLY SWEEPS THRU IN
ENTIRETY, WE'LL SEE 1/2 TO MAYBE 1 INCH TOTALS IN GENERAL SO
THIS WILL LIKELY NOT BE CAUSING ANY BROADER FLOODING ISSUES.
MUCH COLDER AIR IS BROUGHT IN THIS WEEKEND AND EXTENDS INTO
NEXT WEEK, MORE LIKE WHAT JANUARY USUALLY FEELS LIKE. THE
COLDEST TEMPERATURES WILL BE SUNDAY, WHEN HIGHS STRUGGLE
INTO/THRU THE 30S.
AVIATION /00Z TAFS THROUGH 00Z SATURDAY/
ISSUED AT 539 PM CST THU JAN 8 2026
A LINE OF SHOWERS WITH EMBEDDED THUNDERSTORMS WILL SWEEP THROUGH
THE REGION OVERNIGHT, MAINLY BETWEEN 03-12Z. AHEAD OF THE FRONT,
GUSTY GRADIENT WINDS FROM THE SOUTH WILL GUST TO 25-35 KTS, AND
LOCALLY HIGHER GUSTS CANNOT BE RULED OUT UNDER THUNDERSTORM
ACTIVITY. FOLLOWING THE PASSAGE OF THE PRECIPITATION, RAIN AND
THUNDER CHANCES WILL END, WITH VFR CLOUD BASES EXPECTED OUTSIDE
OF MVN. GRADIENT WILL WILL BECOME W-NW AND RELAX AS WELL.
