...HEAVY RAIN WITH LIFE THREATENING FLASH FLOODING WILL CONTINUE
FOR SOUTHERN CALIFORNIA INTO TUESDAY...
...HEAVY SNOW TO IMPACT THE MAJOR MOUNTAIN RANGES FROM THE SIERRA
NEVADA TO THE CENTRAL ROCKIES THROUGH MID-WEEK...
...TEMPERATURES WILL CONTINUE TO RUN WELL ABOVE AVERAGE FROM THE
GREAT PLAINS TO THE APPALACHIANS WITH RECORD BREAKING WARMTH FOR
PARTS OF THE UPPER MIDWEST...
A SLOW MOVING AND RELATIVELY NARROW AXIS OF ANOMALOUS MOISTURE
WILL CONTINUE TO FOCUS ACROSS SOUTHERN CALIFORNIA OVER THE NEXT 12
TO 24 HOURS, MAINTAINING A SIGNIFICANT THREAT FOR LIFE THREATENING
FLASH FLOODING ACROSS THE TRANSVERSE RANGES AND ADJACENT
LOCATIONS. AREAS OF MODERATE TO HEAVY RAIN ARE EXPECTED TO REMAIN
IN PLACE NEAR A COLD FRONT CROSSING THE SOUTHERN COAST OF
CALIFORNIA, JUST AHEAD OF AN UPPER LEVEL TROUGH AXIS. ADDITIONAL
RAINFALL TOTALS THROUGH TUESDAY OF 1-3 INCHES ARE EXPECTED FOR THE
URBAN CORRIDOR FROM LOS ANGELES TO SAN DIEGO AND INTO THE
FOOTHILLS OF THE TRANSVERSE RANGES, WITH LOCALLY HIGHER RAINFALL
TOTALS IN AREAS OF HIGHER TERRAIN. THIS WILL FALL ON TOP OF THE 5
TO 10+ INCHES OF RAIN WHICH HAS IMPACTED SOUTHERN CALIFORNIA OVER
THE PAST 48 HOURS. FLOODING OF STREAMS AND RIVERS ALONG WITH
MUDSLIDES ARE EXPECTED TO REMAIN A THREAT. WHILE RAIN WILL
CONTINUE FOR SOUTHERN CALIFORNIA ON TUESDAY, THE INTENSITY IS
EXPECTED TO BE LIGHTER THAN WHAT OCCURRED OVER THE WEEKEND AS THE
STORM SYSTEM MOVES EAST INTO THE DESERT SOUTHWEST, BUT THE
POTENTIAL FOR FLASH FLOODING AND HIGHER RAINFALL RATES WILL EXPAND
INTO WESTERN ARIZONA, SOUTHERN NEVADA AND SOUTHWESTERN UTAH.
HEAVY SNOW AND STRONG WINDS WILL CONTINUE TO GENERATE NEAR
IMPOSSIBLE TRAVEL CONDITIONS FOR ELEVATIONS AT/ABOVE 5000-7000 FT
FOR SOUTHERN PORTIONS OF THE SIERRA NEVADA INTO THE MOUNTAINS OF
CENTRAL NEVADA. AS THE UPPER TROUGH AND SURFACE COLD FRONT SHIFT
EASTWARD THROUGH MID WEEK, HEAVY SNOW WILL SPREAD EASTWARD INTO
THE HIGHER ELEVATIONS OF UTAH, IDAHO, WYOMING, COLORADO AND NEW
MEXICO.
THE CENTRAL AND EASTERN U.S. WILL REMAIN FAIRLY DRY AFTER A
POWERFUL STORM SYSTEM EXITS FROM THE SOUTHEAST INTO THE WESTERN
ATLANTIC TONIGHT. UPPER LEVEL RIDGING OVER THE CENTRAL U.S. WILL
CONTINUE ANOMALOUSLY WARMTH FOR THE NORTHERN/CENTRAL PLAINS AND
UPPER MIDWEST THROUGH WEDNESDAY. HIGH TEMPERATURES IN THE 40S AND
LOW 50S ARE EXPECTED FOR THE UPPER MIDWEST ON TUESDAY AND
WEDNESDAY, 20-30 DEGREES ABOVE AVERAGE. WHICH WILL LIKELY BREAK
DAILY RECORD HIGH TEMPERATURES. HIGHS TEMPERATURES GENERALLY FROM
THE ROCKIES TO THE NORTHEAST WILL BE ABOVE AVERAGE AND MILD.
