...PACIFIC STORM SYSTEM CONTINUES TO BRING LOWER ELEVATION RAIN
AND HAZARDOUS MOUNTAIN SNOW TO PORTIONS OF THE NORTHWEST U.S.
THROUGH MONDAY...
...UNSETTLED WEATHER AND COOL TEMPERATURES WILL IMPACT MUCH OF THE
EASTERN GULF COAST REGION AND SOUTHEAST U.S. GOING THROUGH MONDAY,
WHICH WILL INCLUDE CONCERNS THIS EVENING AND OVERNIGHT FOR SOME
ADDITIONAL SEVERE WEATHER AND FLASH FLOODING CONCERNS...
...A NEW STORM SYSTEM WILL ORGANIZE ACROSS THE MIDDLE AND LOWER
MISSISSIPPI VALLEYS BY MIDWEEK...
A STORM SYSTEM IMPACTING PORTIONS OF THE PACIFIC NORTHWEST AND
NORTHERN CALIFORNIA WILL MOVE THROUGH THE GREAT BASIN AND INTERIOR
OF THE NORTHWEST THROUGH MONDAY WHICH WILL BRING ADDITIONAL FOCUS
FOR LOWER ELEVATION RAINFALL, AND LOCALLY HEAVY ACCUMULATING SNOW
FOR THE HIGHER ELEVATIONS. IN FACT, PORTIONS OF THE NORTHERN
ROCKIES MAY SEE AS MUCH AS 12 TO 18 INCHES OF NEW SNOWFALL BY LATE
MONDAY AS A COMBINATION OF PACIFIC MOISTURE AND MULTIPLE WAVES OF
LOW PRESSURE TRAVERSING A FRONTAL BOUNDARY CROSSES THROUGH THE
INTERMOUNTAIN REGION. THIS SYSTEM WILL ALSO BE SPILLING OUT ACROSS
THE NORTHERN AND CENTRAL PLAINS ON MONDAY, AND SHOWERS AND
THUNDERSTORMS ARE EXPECTED TO BREAK OUT ALONG A COLD FRONT WITH A
FOCUS ON THE DAKOTAS. BY TUESDAY, THIS COLD FRONT WILL BE SWEEPING
WELL TO THE EAST ACROSS MUCH OF THE PLAINS REGION, AS FAIRLY
STRONG HIGH PRESSURE BUILDS BEHIND IT ACROSS THE INTERMOUNTAIN
WEST. THIS WILL ALLOW CONDITIONS TO GRADUALLY DRY OUT, BUT COLDER
TEMPERATURES WILL FOLLOW WITH HIGH TEMPERATURES AS MUCH AS 10 TO
15 DEGREES BELOW NORMAL ACROSS MUCH OF THE NORTHWEST U.S. OVER THE
NEXT COUPLE OF DAYS.
MEANWHILE, A SLOW-MOVING STORM SYSTEM STRETCHING FROM THE LOWER
OHIO VALLEY AND MID-SOUTH DOWN THE CENTRAL GULF COAST WILL
CONTINUE TO GRADUALLY EJECT OFF TO THE EAST OVER THE NEXT COUPLE
OF DAYS, BUT WITH LOW PRESSURE BECOMING MORE FOCUSED NEAR THE
EASTERN GULF COAST AND THEN CONSOLIDATING OFFSHORE OF THE
SOUTHEAST U.S. ON TUESDAY. IN THE SHORT-TERM GOING THROUGH THIS
EVENING AND OVERNIGHT, AREAS OF HEAVY SHOWERS AND THUNDERSTORMS
WILL CONTINUE TO IMPACT AREAS OF ESPECIALLY SOUTHERN ALABAMA AND
INTO THE FLORIDA PANHANDLE WHERE SOME LOCALIZED AREAS OF SEVERE
THUNDERSTORMS AND POTENTIAL FOR FLASH FLOODING WILL CONTINUE. THE
STORM PREDICTION CENTER HAS DEPICTED A SLIGHT RISK (LEVEL 2/5) TO
ADDRESS CONCERNS FOR SOME DAMAGING WIND POTENTIAL AND A COUPLE OF
TORNADOES. WITH LOCALLY A FEW INCHES OF RAIN POSSIBLE, THE WEATHER
PREDICTION CENTER AS DEPICTED A SLIGHT RISK OF EXCESSIVE RAINFALL
(LEVEL 2/4). FARTHER EAST ACROSS PORTIONS OF EAST-CENTRAL FLORIDA
INCLUDING THE SPACE COAST, LOCALLY VERY HEAVY AND SLOW-MOVING
SHOWERS AND THUNDERSTORMS WILL BE A CONCERN THIS EVENING AND
OVERNIGHT WITH LOCALLY SEVERAL INCHES OF RAIN POSSIBLE NEAR A
FRONTAL ZONE AS VERY MOIST EASTERLY ATLANTIC FLOW IMPACTS THE
REGION. A SLIGHT RISK (LEVEL 2/4) OF EXCESSIVE RAINFALL HAS BEEN
DEPICTED HERE AS WELL. LOCALLY HEAVY RAINS WITH THIS BROADER STORM
SYSTEM WILL ALSO IMPACT AREAS OF THE SOUTHERN APPALACHIANS AND
INTERIOR OF THE SOUTHEAST ON MONDAY. LOW PRESSURE WILL BEGIN TO
PULL AWAY FROM THE SOUTHEAST U.S. ON TUESDAY, BUT LINGERING CLOUDS
AND LIGHT RAIN WILL HELP KEEP TEMPERATURES RATHER COOL FOR THIS
TIME OF THE YEAR, WITH HIGH TEMPERATURES EXPECTED TO BE WELL BELOW
NORMAL ACROSS MUCH OF THE SOUTHEAST FOR THE EARLY PART OF THE WEEK.
BY MIDWEEK, THE AFOREMENTIONED UNSETTLED WEATHER AND ASSOCIATED
COLD FRONT EJECTING OUT OF THE WEST AND CROSSING THE PLAINS WILL
BEGIN TO DIG INTO THE MIDDLE AND LOWER MISSISSIPPI VALLEY REGION.
A MORE WIDESPREAD AREA OF HEAVY SHOWERS AND THUNDERSTORMS WILL
BEGIN TO OVERSPREAD AREAS OF THE MIDWEST ON DOWN TO THE NORTHWEST
GULF COAST REGION BEGINNING BY TUESDAY EVENING AND INTO WEDNESDAY.
THIS WILL THEN RELOAD WIDESPREAD UNSETTLED WEATHER AND COOL
TEMPERATURES ACROSS MUCH OF THE OHIO AND TENNESSEE VALLEY REGION
AND INTO THE SOUTHEAST U.S. ON WEDNESDAY.
