DISCUSSION
ISSUED AT 234 AM EDT SAT MAR 28 2026
SHOWERS ASSOCIATED WITH A COLD FRONT HAVE EXITED OUR AREA, AND A
COOLER AND DRIER AIR MASS WILL BUILD INTO THE AREA THROUGH TODAY.
THE MAIN CONCERN TODAY WILL BE THE ELEVATED FIRE WEATHER CONDITIONS.
RH VALUES TODAY WILL BE IN LOWER 20S FOR MOST AREAS, WITH NORTH
WINDS GUSTING UP TO 25 MPH IN VALLEY LOCATIONS AND TO AROUND 30
MPH ACROSS THE HIGHEST ELEVATIONS OF THE EAST TN MOUNTAINS. AN
ENHANCED FIRE DANGER STATEMENT IS IN EFFECT FOR TODAY FOR AREAS
SOUTH OF I-40. AN ADDITIONAL ENHANCED FIRE DANGER STATEMENT IS
LIKELY FOR SUNDAY AS WELL DUE TO LOW RH VALUES, ALTHOUGH WINDS ARE
EXPECTED TO BE LOWER THAN TODAY.
MUCH COLDER TEMPERATURES ARE EXPECTED OVERNIGHT WITH NEAR FREEZING
TO BELOW FREEZING TEMPS ACROSS OUR NORTHERN AREAS (NORTHERN
CUMBERLAND PLATEAU, NORTHEAST TN, SOUTHWEST VA,) AS WELL AS THE
HIGHER ELEVATIONS OF THE EAST TN MOUNTAINS. WITH THE BREEZY WINDS
BEHIND THE FRONT, WIND CHILLS WILL DROP INTO THE TEENS ACROSS
NORTHERN AREAS, WITH SINGLE DIGIT WIND CHILLS IN THE EAST TN
MOUNTAINS. LOWS NEAR FREEZING ARE EXPECTED AGAIN SUNDAY MORNING IN
THE MOUNTAINS AND NORTHERN SECTIONS, BUT LIGHT WINDS WILL NOT RESULT
IN SIGNIFICANTLY LOWER WIND CHILL VALUES.
THE FIRST HALF OF NEXT WEEK WILL FEATURE MAINLY DRY WEATHER AND
WARMING TEMPERATURES, WITH HIGHS IN THE 80S RETURNING ON TUESDAY.
RAIN CHANCES WILL RAMP UP ON WEDNESDAY AS A COLD FRONT MOVES SOUTH
ACROSS THE OH VALLEY AND SETTLES ACROSS WV/KY/TN WEDNESDAY NIGHT AS
IT BECOMES PARALLEL TO THE MIDLEVEL FLOW. A SERIES OF UPPER
DISTURBANCES IN THE SW FLOW, COMBINED WITH THE POTENTIAL FOR A
STATIONARY FRONT NEAR THE AREA, MAY RESULT IN A RAINY PERIOD THROUGH
THE LATTER HALF OF NEXT WEEK. THIS MAY BE BENEFICIAL FOR THE CURRENT
DROUGHT CONDITIONS AND FIRE CONCERNS.
