DISCUSSION
(TODAY THROUGH NEXT THURSDAY)
ISSUED AT 300 AM CST FRI NOV 21 2025
TODAY & TONIGHT:
A SERIES OF MID-LEVEL IMPULSES WILL TRANSLATE ACROSS THE REGION
THROUGH TONIGHT. MOISTURE ADVECTION AND BROAD ASCENT WILL SPAWN
SEVERAL PROGRESSIVE BATCHES/CLUSTERS OF SHOWERS AND A FEW
THUNDERSTORMS. FORECAST SOUNDINGS SHOW THE LOW LEVELS TO ONLY BE
WEAKLY UNSTABLE AT BEST, THOUGH A FEW HUNDRED J/KG OF MUCAPE WILL
EXIST, WITH BULK SHEAR NEARING 40 KNOTS AND A DECENTLY VEERED WIND
PROFILE. A COUPLE CELLS MAY ACQUIRE MODEST INTENSITY, OFFERING:
DOWNPOURS AND PERHAPS BRIEF GUSTY WINDS AND TRANSIENT, "MINI-
SPINNY" STRUCTURES (BRIEF TORNADO THREAT IS QUITE LOW).
THE WEEKEND:
WE SHOULD BE ON THE TAIL END OF THE BRUNT OF SHOWER AND
THUNDERSTORM ACTIVITY EARLY SATURDAY MORNING AS THE LAST MID-LEVEL
IMPULSE MOVES BY. THROUGH THE REST OF THE DAY, IMPROVED
CONDITIONS ARE FORECAST, THOUGH A LOW CHANCE FOR A FEW LIGHT
SHOWERS REMAINS AS THE FRONT ASSOCIATED WITH FRIDAY'S SYSTEM NEARS
THE REGION. PRIOR TO FRONTAL PASSAGE, MODEL GUIDANCE CONTINUES TO
SHOW HIGH TEMPERATURES NEAR THE DAILY RECORD FOR A FEW CLIMATE
SITES.
CLEAR AND COOLER CONDITIONS ARRIVE FOR THE SECOND-HALF OF THE
WEEKEND.
EARLY TO MID NEXT WEEK:
TEMPERATURES ARE FORECAST TO REBOUND BY A FEW DEGREES EARLY NEXT
WEEK, HOLDING ABOVE SEASONAL NORMALS. MONDAY LOOKS RAIN-FREE AS A
SHORTWAVE RIDGE MOVES ACROSS THE AREA. A PAIR OF TROUGHS WILL BE
ON ITS HEELS AND BRING A ROUND OF SHOWERS AND THUNDERSTORMS.
ENSEMBLES MAINTAIN THE PRIMARY WINDOW BEING TUESDAY INTO TUESDAY
NIGHT; HOWEVER, THERE'S A DECENT AMOUNT OF GFS/ECMWF ENSEMBLES
THAT SHOW A SLOWER PASSAGE OF THE SYSTEM, RESULTING IN LINGERING
ACTIVITY INTO WEDNESDAY. INSTABILITY/SHEAR PARAMETERS SUGGEST A
LOW SEVERE WEATHER RISK COULD MATERIALIZE, THOUGH THE MAIN LOBE OF
FORCING QUICKLY EJECTS TO THE NORTHEAST EARLY IN THE EVENT. WE
MAINTAIN THE SAME POSTURE OF THE PAST COUPLE OF DAYS: WATCHING BUT
NO FORMAL INCLUSION IN THE OFFICIAL FORECAST.
THANKSGIVING DAY:
IT LOOKS LIKE WE'LL GET THE EARLY-WEEK RAINMAKER OUT OF HERE IN
TIME FOR THANKSGIVING. THE CURRENT FORECAST FEATURES FAIR-WEATHER
CONDITIONS AND COOL TEMPERATURES.
