THIS GENERAL SETUP SHOULD CONTINUE INTO SATURDAY, ALBEIT A BIT
FLATTER AS BOTH THE UPPER HIGH OVER THE DESERT SW AND THE EASTERN
CONUS TROUGH WEAKEN SOMEWHAT, AND SHIFTS FURTHER TO THE EAST. THIS
PROCESS SHOULD RESULT IN CONTINUED DRY WEATHER INTO FRIDAY, WITH
DAILY HIGH AND LOW TEMPERATURES GRADUALLY WARMING.
BEFORE THEN, STILL COLD AIR WAS IN PLACE ALONG WITH LIGHT WINDS
AND AIR TEMPERATURES CHILLING INTO THE LOW/MID 30S OVER NE
ALABAMA WAS PRESENTING RISKS OF LATE NIGHT FROSTING. SO HAVE
ISSUED A FROST ADVISORY THAT WILL BE IN EFFECT UNTIL 8 AM CDT FOR
DEKALB, JACKSON, AND MARSHALL COUNTIES OF NE ALABAMA. A LOOK AT
VARIOUS MESONET/BACKYARD WEATHER STATIONS INDICATED TEMPERATURES
IN THE LOW/MID 30S OVER PARTS OF THOSE COUNTIES.
OTHERWISE, ADDITIONAL HIGH ALTITUDE CLOUDS MOVING IN FROM THE NW

A GRADUAL WARMING TREND IS FORECAST THROUGH THE END OF THE WORK

LEVEL RIDGE ACROSS THE WESTERN CONUS SHIFTS EASTWARD BRINGING BACK
SOUTHERLY SFC FLOW. DRY CONDITIONS WILL PERSIST THROUGH THE SHORT

AND LOWER 80S BY SATURDAY. OVERNIGHT LOWS REMAIN MILD AS WELL IN
THE MID 50S.

WARM CONDITIONS CONTINUE ON SUNDAY AS THE INFLUENCE OF HIGH
PRESSURE TO OUR WEST REMAINS STRONG. EXPECT HIGHS TO ONCE AGAIN
RETURN TO THE LOW TO MID 80S. A COLD FRONT ATTEMPTS TO PUSH
THROUGH SUNDAY NIGHT INTO MONDAY, BUT ENSEMBLE GUIDANCE KEEPS THE
AREA DRY. THIS WILL BE A FEATURE TO WATCH, AS LATEST MODEL
GUIDANCE DOES SHOW PRECIP ACROSS KY/N TN. HOWEVER, IT WILL BE A
BIT COOLER TO START THE WORK WEEK WITH TEMPERATURES ON MONDAY
THROUGH WEDNESDAY IN THE UPPER 60S TO LOWER 70S. BEHIND THE COLD
FRONT, NORTHWEST FLOW TAKES SHAPE BRINGING A SERIES OF SHORTWAVE
THROUGH THE AREA. LOTS OF UNCERTAINTY IN TIMING OF THESE FEATURES,
BUT AT LEAST A LOW CHANCE OF SHOWERS IS EXPECTED TUESDAY INTO
WEDNESDAY.
