.MESOSCALE UPDATE FOR OVERNIGHT SEVERE STORM THREAT
... ISSUED AT 1035 PM CST FRI NOV 21 2025
A CLUSTER OF STORMS IS APPROACHING LAND-BETWEEN-THE-LAKES, JUST
AHEAD OF A COLD FRONT THAT IS POISED TO SWEEP ACROSS MIDDLE
TENNESSEE OVERNIGHT. THE MID STATE REMAINS UNDER A MARGINAL RISK
OF SEVERE STORMS, WITH STRAIGHT-LINE WINDS THE MAIN THREAT; THE
TORNADO RISK IS NOW LESS THAN 2%. THE EXISTING STORMS ARE OCCURING
IN A BAND OF ~1,000 J/KG CAPE. THE HRRR BRINGS THE CELLS UP TO
AROUND CLARKSVILLE, THEN WEAKENING THEREAFTER OWING TO DECREASING
INSTABILITY. SO THE SEVERE THREAT WILL CONTINUE TO DIMINISH AS WE
HEAD INTO THE OVERNIGHT PERIOD.
SHORT TERM
(TONIGHT THROUGH SUNDAY NIGHT)
ISSUED AT 1026 PM CST FRI NOV 21 2025
CLOUDS HAVE BLANKETED THE SKIES OVER MIDDLE TENNESSEE THIS EVENING.
A LINE OF STORMS IS APPROACHING STEWART COUNTY CURRENTLY, THIS WILL
BE OUR SEVERE THREAT FOR THE EVENING. A MARGINAL RISK (LEVEL 1 OUT
OF 5) BUT STILL SOMETHING TO WATCH, ESPECIALLY BEING AN OVERNIGHT
RISK. WE'RE PRETTY SATURATED, HOWEVER, AND CLOUD COVER HAS BEEN AN
ISSUE ALL DAY. SEE THE MESOSCALE UPDATE FOR MORE INFORMATION ON THE
THREAT SPECIFICALLY.
LOWS TONIGHT WILL BE A BIT WARMER: CLOSER TO 60 DEGREES AND THE
UPPER 50S. ONCE THE COLD FRONT MOVES THROUGH SATURDAY, TEMPERATURES
WILL DROP INTO THE 40S FOR LOWS. NOT MUCH OF A DIFFERENCE FOR HIGHS
POST-FRONTAL, BUT THE AIRMASS SHOULD FEEL DRIER WHICH WILL HELP IT
FEEL COOLER.
LONG TERM
(MONDAY THROUGH NEXT SATURDAY)
ISSUED AT 1026 PM CST FRI NOV 21 2025
PATCHY FOG WILL CONTINUE TO BE A THREAT THROUGH THE BEGINNING OF THE
WORK WEEK IN THE MORNING HOURS, SO USE CAUTION ON YOUR COMMUTES.
ANOTHER CHANCE FOR SHOWERS AND THUNDERSTORMS ARRIVES IN THE FORECAST
BEGINNING MONDAY MORNING. A LOW PRESSURE SYSTEM LOOKS TO PASS TO OUR
NORTH, WITH A COLD FRONT EXTENDING SOUTH INTO THE MIDSTATE.
CURRENTLY, IT'S HARD TO SAY IF THERE WILL BE ANY SEVERE WEATHER WITH
THIS SYSTEM, BUT IT DOESN'T LOOK PROMISING RIGHT NOW. MORE ON THE
MARGINAL SIDE IN THE GUIDANCE IF ANYTHING, THANKS TO WEAK CAPE AND
PALTRY LAPSE RATES CONTINUING TO BE THE NORM IN FORECAST SOUNDINGS
ACROSS THE AREA. A HIGH PRESSURE SYSTEM MOVES IN AFTER THIS SYSTEM,
LEAVING DRY CONDITIONS FOR THE THANKSGIVING HOLIDAY. THE COLD FRONT
WITH THE AFOREMENTIONED LOW LOOKS TO BE STRONGER, WITH LOW
TEMPERATURES DROPPING INTO THE 20S AND 30S BY THE END OF THE WEEK.
AVIATION
