...HEAVY RAIN AND SEVERE WEATHER EXPECTED TO SPREAD ACROSS
PORTIONS OF THE CENTRAL/SOUTHERN PLAINS TODAY; THEN ACROSS THE
LOWER MISSISSIPPI VALLEY AND THE CENTRAL TO EASTERN GULF COAST ON
THURSDAY...
...HEAVY WET SNOW OVER CENTRAL COLORADO IS EXPECTED TO TAPER OFF
LATER TODAY BUT MORE WET SNOW IS EXPECTED BY THURSDAY NIGHT...

THE EAST OF THE ROCKIES, WHILE ABOVE AVERAGE TEMPERATURES EXPAND
ACROSS THE WEST...
...ELEVATED FIRE WEATHER DANGER ACROSS THE SOUTHERN ROCKIES TO
SOUTHERN HIGH PLAINS; SLIGHT RISK OF SEVERE THUNDERSTORMS FOR
CENTRAL FLORIDA TODAY...
A LOW PRESSURE SYSTEM DEVELOPING OVER THE SOUTHERN HIGH PLAINS
WILL SPREAD SHOWERS AND THUNDERSTORMS OUT ACROSS THE
CENTRAL/SOUTHERN PLAINS TODAY. THE HIGHEST CHANCE OF HEAVY RAIN
TODAY IS EXPECTED TO BE IN THE COOL SECTOR TO THE NORTH OF A
STATIONARY FRONT FROM SOUTHEASTERN COLORADO ACROSS THE TEXAS
PANHANDLE AND INTO MUCH OF OKLAHOMA. SEVERE THUNDERSTORMS
ACCOMPANIED BY POCKETS OF HEAVY RAINFALL ARE EXPECTED FARTHER
SOUTH ACROSS NORTHERN TEXAS AHEAD OF THE LOW PRESSURE SYSTEM AND
ALONG THE STATIONARY FRONT. BY THURSDAY, THE SHOWERS AND STORMS
WILL PUSH EASTWARD INTO THE LOWER TO MID-MISSISSIPPI VALLEY, WITH
THE HIGHEST CHANCE OF SEVERE WEATHER ALONG THE CENTRAL GULF COAST.
THE EXCESSIVE RAINFALL THREAT IS FORECAST TO BE MARGINAL ACROSS
THE DEEP SOUTH AND INTO THE TENNESSEE VALLEY. BY EARLY FRIDAY,
MODERATELY HEAVY RAIN IS EXPECTED TO REACH INTO THE OHIO VALLEY,
THE APPALACHIANS AND DOWN INTO THE SOUTHEAST.
MEANWHILE, ONGOING HEAVY WET SNOW ON THE BACKSIDE OF THIS STORM
SYSTEM ACROSS CENTRAL COLORADO IS FORECAST TO TAPER OFF AS THE
SYSTEM MOVES FARTHER AWAY. HOWEVER, ANOTHER COLD UPPER TROUGH IS
FORECAST TO PLUNGE SOUTHWARD INTO THE NORTHERN ROCKIES ON
THURSDAY, REACHING CENTRAL ROCKIES BY FRIDAY MORNING. THIS SYSTEM
WILL BRING A QUICK ROUND OF MOUNTAIN SNOW AND LOWER ELEVATION RAIN
FROM NORTH TO SOUTH ACROSS THE NORTHERN AND CENTRAL ROCKIES AND
NEARBY HIGH PLAINS BEGINNING ON THURSDAY. THE COLORADO ROCKIES
AND NEARBY FRONT RANGE WILL LIKELY SEE ANOTHER ROUND OF WET SNOW,
POSSIBLY LOCALLY HEAVY, BY THURSDAY NIGHT INTO FRIDAY MORNING.
MEANWHILE, SCATTERED SHOWERS ARE ALSO EXPECTED TO SPREAD INTO THE
NORTHERN PLAINS AS A LOW PRESSURE WAVE DEVELOPS ALONG A FRONT.
ACROSS FLORIDA, A WEAK SHORTWAVE TROUGH MOVING OVER SEA BREEZE
BOUNDARIES TODAY IS EXPECTED TO PRODUCE SCATTERED THUNDERSTORMS,
WITH HAIL AND/OR DAMAGING WIND GUSTS POSSIBLE WITHIN STRONGER
STORMS.
CONTINUED TROUGHING EAST OF THE ROCKIES WILL GENERATE BELOW
AVERAGE TEMPERATURES OVER THE NEXT FEW DAYS. HIGH TEMPERATURES
WILL BE 15-25 DEGREES BELOW AVERAGE ACROSS PORTIONS OF
SOUTHEASTERN COLORADO, KANSAS AND OKLAHOMA, ON THE BACKSIDE OF THE
AFOREMENTIONED SOUTHERN PLAINS STORM SYSTEM, ON WEDNESDAY. THIS
WILL RESULT IN HIGH TEMPERATURE READINGS IN THE UPPER 40S TO 50S
FOR MANY PARTS OF THE CENTRAL/SOUTHERN PLAINS. TEMPERATURES
MODERATE A BIT ON THURSDAY OVER THOSE AREAS. AN UPPER RIDGE WILL
CONTINUE TO BRING ANOMALOUS WARMTH TO THE WEST OVER THE NEXT
SEVERAL DAYS WITH HIGH TEMPERATURES REACHING 15-25 DEGREES ABOVE
NORMAL IN MANY PLACES. DRY AND WINDY CONDITIONS WILL KEEP AN
ELEVATED FIRE DANGER FOR PORTIONS OF NEW MEXICO INTO WESTERN
TEXAS FOR THE NEXT COUPLE OF DAYS.
