HEAVY SNOW AND BLIZZARD CONDITIONS ASSOCIATED WITH A DEEP
MID-LATITUDE CYCLONE IMPACTING THE NORTHERN/CENTRAL PLAINS AND
UPPER MIDWEST WILL COME TO AN END TODAY. ADDITIONAL SNOWFALL
ACCUMULATIONS OF 2-4 INCHES ARE EXPECTED ACROSS EASTERN MINNESOTA
BY WEDNESDAY MORNING, WHEN THE SYSTEM IS FORECAST TO MOVE INTO
ONTARIO/SOUTHERN CANADA. A FRIGID AIRMASS WILL CONTINUE TO SPREAD
ACROSS THE GREAT PLAINS TODAY AND WEDNESDAY BEHIND A COLD FRONT.
HIGHS WILL BE 15-25 DEGREES BELOW AVERAGE FOR MUCH OF THE PLAINS
TODAY. TEMPERATURES WILL MODERATE LATER THIS WEEK.
RAIN SHOWERS AND SCATTERED TO ISOLATED THUNDERSTORM ACTIVITY ARE
LIKELY EAST OF THE MISSISSIPPI RIVER TODAY. STORMS WILL ORGANIZE
ALONG A PAIR OF COLD FRONTS ASSOCIATED WITH TWO SEPARATE LOW
PRESSURE SYSTEMS; THE UPPER MIDWEST SYSTEM AND THE GULF COAST
SYSTEM. THE STORM PREDICTION CENTER ISSUED A SLIGHT RISK OF SEVERE
THUNDERSTORMS (LEVEL 2/5) FOR PARTS OF THE SOUTHERN GREAT LAKES
AND FOR PORTIONS OF THE GULF COAST TODAY. DAMAGING WIND GUSTS WILL
BE THE MAIN THREAT FOR BOTH AREAS, BUT A BRIEF TORNADO CAN'T BE
RULED OUT OVER THE GULF COAST. THE GULF SYSTEM IS FORECASTED TO
STALL OUT OVER THE SOUTHEAST/FLORIDA PANHANDLE THIS
AFTERNOON/EVENING LEADING TO POTENTIALLY HEAVY RAINFALL OCCURRING
PARTICULARLY OVER THE FLORIDA PANHANDLE. SIGNIFICANT MOISTURE
RETURN FROM THE GULF WILL INTERACT WITH THE SLOW MOVING COLD
FRONT, WHICH WILL PRODUCE AN AXIS OF 2-4 INCHES OF RAIN FROM
NORTHERN FLORIDA THROUGH THE SOUTHEAST COAST ON WEDNESDAY. A
SLIGHT RISK (AT LEAST 15%) OF EXCESSIVE RAINFALL LEADING TO FLASH
FLOODING IS IN EFFECT FOR PARTS OF NORTH-CENTRAL FLORIDA INTO
SOUTHERN GEORGIA.
A DEEP LOW PRESSURE SYSTEM WILL BRING ANOTHER ROUND OF UNSETTLED
WEATHER TO THE NORTHWEST BEGINNING ON WEDNESDAY. LOW ELEVATION
RAIN AND MOUNTAIN SNOW ARE EXPECTED FROM THIS SYSTEM. ACCUMULATING
SNOW SHOULD REMAIN CONFINED TO THE HIGHER ELEVATIONS OF THE
CASCADES, SIERRA NEVADA AND NORTHERN ROCKIES. SOME 1-2 INCH 24
HOUR RAINFALL TOTALS POSE A MARGINAL RISK (AT LEAST 5%) OF
EXCESSIVE RAINFALL LEADING TO FLASH FLOODING OVER PARTS OF THE
NORTHERN CALIFORNIA INTO SOUTHERN OREGON COASTLINE.
