SHOWERS AND THUNDERSTORMS WILL CONTINUE INTO THE EARLY MORNING

WINTRY MIX IS EXPECTED FOR PORTIONS OF THE INTERIOR NORTHEAST,
PARTICULARLY FOR HIGHER ELEVATIONS, WHERE SOME LIGHT SNOW
ACCUMULATIONS WILL BE POSSIBLE. PRECIPITATION WILL LINGER LONGEST
THROUGH PORTIONS OF THE INTERIOR NORTHEAST AND THE APPALACHIANS AS
A SECONDARY COLD FRONT WILL BRING ANOTHER ROUND OF RAIN/SNOW

OF THE CENTRAL AND EASTERN U.S. WILL BE DRY TO START THE WORK
WEEK. THE EXCEPTION WILL BE ALONG THE LINGERING FRONTAL BOUNDARY
THROUGH SOUTH FLORIDA AS WELL AS INTO PORTIONS OF TEXAS. AN
UPPER-LEVEL SHORTWAVE WILL LEAD TO INCREASED THUNDERSTORM COVERAGE
ON MONDAY ACROSS SOUTH AND CENTRAL TEXAS, WHERE SOME ISOLATED
FLASH FLOODING IS POSSIBLE. GUSTY WINDS AND VERY DRY CONDITIONS
WILL BRING A THREAT OF FIRE WEATHER TODAY FOR PORTIONS OF THE
SOUTHERN HIGH PLAINS, PARTICULARLY FOR NORTHEAST NEW MEXICO,
SOUTHEAST COLORADO, SOUTHWESTERN KANSAS, AND THE OKLAHOMA/TEXAS
PANHANDLES WHERE THE STORM PREDICTION CENTER HAS OUTLINED A
CRITICAL RISK (LEVEL 2/3).
AN APPROACHING DEEP UPPER-LEVEL LOW AND FRONTAL SYSTEM OVER THE
PACIFIC WILL BRING INCREASING PRECIPITATION CHANCES TO THE WEST
COAST OVER THE NEXT COUPLE OF DAYS. SOME LIGHT SHOWERS WILL BE
POSSIBLE TODAY FOR NORTHERN CALIFORNIA BEFORE MORE WIDESPREAD,
MODERATE TO LOCALLY HEAVY RAINFALL MOVES IN TO NORTHERN/CENTRAL
CALIFORNIA ON MONDAY. COVERAGE WILL FURTHER EXPAND TUESDAY
INCLUDING INTO THE PACIFIC NORTHWEST, SOUTHERN CALIFORNIA, AND
PORTIONS OF THE GREAT BASIN. ISOLATED FLOODING WILL BE POSSIBLE
ALONG THE NORTHERN/CENTRAL COASTAL RANGES OF CALIFORNIA AS WELL AS
THE SIERRA. HEAVY HIGH ELEVATION SNOW IS ALSO EXPECTED FOR THE
SIERRA ON TUESDAY.
CHILLIER, BELOW AVERAGE TEMPERATURES HAVE ARRIVED FOR MUCH OF THE
EASTERN HALF OF THE COUNTRY FOLLOWING A COLD FRONT PASSAGE THIS
WEEKEND. FORECAST HIGHS THE NEXT COUPLE OF DAYS WILL BE IN THE 40S
AND 50S ACROSS THE MIDWEST AND NORTHEAST, WITH 60S AND SOME 70S
ACROSS THE SOUTHERN TIER FROM TEXAS INTO THE SOUTHEAST AND
SOUTHERN PORTIONS OF THE MID-ATLANTIC. MEANWHILE, A STRENGTHENING
UPPER-LEVEL RIDGE AHEAD OF THE APPROACHING PACIFIC SYSTEM WILL
BRING ABOVE TO WELL ABOVE AVERAGE CONDITIONS ACROSS THE WESTERN
U.S. HIGHS ACROSS THE INTERIOR WEST WILL BE INTO THE 60S, 70S, AND
POSSIBLY EVEN THE LOW 80S, AND THE DESERT SOUTHWEST WILL SEE HIGHS
INTO THE 90S. THESE WARMER TEMPERATURES WILL ALSO SPREAD INTO
PORTIONS OF THE NORTHERN/CENTRAL PLAINS BY MONDAY AS HIGHS SOAR
INTO THE 70S AND 80S AFTER A CHILLY WEEKEND. TEMPERATURES ALONG
THE WEST COAST WILL VARY AROUND AVERAGE AS THE PACIFIC SYSTEM
APPROACHES, WITH HIGHS IN THE 60S AND 70S.
