...BELOW AVERAGE TEMPERATURES FOR LARGE PORTIONS OF THE NATION TO
THE EAST OF THE ROCKIES, WHILE ABOVE AVERAGE TEMPERATURES EXPAND
ACROSS THE WEST...
...HEAVY RAINS, ISOLATED FLASH FLOODING AND SEVERE WEATHER
POSSIBLE ACROSS PORTIONS OF THE CENTRAL TO SOUTHERN PLAINS...
...ELEVATED TO CRITICAL FIRE WEATHER CONDITIONS TO PERSIST ACROSS
THE SOUTHERN HIGH PLAINS...
A COOL SPRING WEATHER PATTERN ON TAP FOR THE NEXT FEW DAYS FOR
MOST AREAS TO THE EAST OF THE ROCKIES. A BROAD MID TO UPPER LEVEL
TROF WILL REMAIN ENTRENCHED ACROSS MUCH OF THE CENTRAL TO EASTERN
HALF OF THE NATION, SUPPORTING BELOW AVERAGE TEMPERATURE OVER THE
NEXT FEW DAYS FOR MOST AREAS TO THE EAST OF THE ROCKIES. HIGH
TEMPERATURES ARE EXPECTED TO BE 5 TO 15 DEGREES BELOW AVERAGE
ACROSS THESE REGIONS. A SMALL REGION ACROSS THE CENTRAL TO
SOUTHERN PLAINS WILL SEE HIGH TEMPERATURES AS MUCH AS 20 TO 25
DEGREES BELOW AVERAGE OVER THE NEXT FEW DAYS. THIS WILL BE
ASSOCIATED WITH AN AREA OF POTENTIALLY HEAVY RAINS THAT SPREAD
EAST SOUTHEASTWARD ACROSS PORTIONS OF THE CENTRAL TO SOUTHERN
PLAINS FROM SOUTHEAST COLORADO, WESTERN AND SOUTHERN KANSAS, ALL
OF OKLAHOMA AND NORTHERN TEXAS. THESE HEAVY RAINS MAY LEAD TO
ISOLATE AREAS OF FLASH FLOODING ACROSS THESE REGIONS. SEVERE
WEATHER IS ALSO POSSIBLE WITH THIS AREA OF HEAVY RAINS, ESPECIALLY
ALONG THE SOUTHERN EDGE OF THE HEAVY PRECIPITATION REGION ACROSS
NORTHERN AND CENTRAL PORTIONS OF TEXAS.
FARTHER TO THE SOUTH AND WEST ACROSS THE SOUTHERN HIGH PLAINS, DRY
CONDITIONS ARE EXPECTED TO PERSIST OVER THE NEXT SEVERAL DAYS.
THESE DRY CONDITIONS, COMBINED WITH LOW RELATIVE HUMIDITIES AND
GUSTY WINDS WILL KEEP THE FIRE WEATHER THREAT AT AN ELEVATED TO
CRITICAL LEVEL OVER THE NEXT FEW DAYS ACROSS LARGE PORTIONS OF NEW
MEXICO, FAR SOUTHEASTERN ARIZONA AND SOUTHWEST TEXAS. FIRE
WEATHER WATCHES ARE CURRENTLY IN EFFECT ACROSS THESE REGIONS.
THE COOL SPRING WEATHER PATTERN WILL ALSO SUPPORT POTENTIAL FOR
WIDESPREAD FROSTS AND FREEZES EARLY TUESDAY MORNING ACROSS THE
UPPER OHIO VALLEY, THE SOUTHERN TO CENTRAL APPALACHIANS AND
PORTIONS OF THE MID-ATLANTIC. FREEZE WARNINGS AND FROST ADVISORIES
ARE CURRENTLY IN EFFECT FOR THESE REGIONS. MORNING TEMPERATURES
WILL ALSO LIKELY FALL TO BELOW FREEZING LEVELS BOTH TUESDAY AND
WEDNESDAY MORNINGS FROM THE NORTHERN PLAINS, INTO THE UPPER
MISSISSIPPI VALLEY AND UPPER LAKES REGIONS.
WHILE BELOW AVERAGE TEMPERATURES GRIP MUCH OF THE CENTRAL TO
EASTERN U.S. EARLY THIS WEEK, ABOVE AVERAGE TEMPERATURES WILL BE
EXPANDING ACROSS MUCH OF THE WESTERN U.S. THIS MUCH ABOVE AVERAGE
TEMPERATURE PATTERN WILL LIKELY CONTINUE THROUGH THE REMAINDER OF
THE WEEK WITH A GRADUAL INCREASE IN TEMPERATURES EACH DAY. THIS
MAY LEAD TO SOME RECORD HIGH TEMPERATURE POTENTIAL FOR PORTIONS OF
NORTHERN CALIFORNIA, WESTERN OREGON AND WESTERN WASHINGTON STATE
TOWARD THE END OF THE WORK WEEK.
