MISSISSIPPI VALLEY AND CENTRAL GULF COAST...

A POWERFUL STORM SYSTEM WILL IMPACT THE NORTHERN/CENTRAL PLAINS
INTO THE UPPER MIDWEST THROUGH TUESDAY. PERIODS OF SNOW AND GUSTY
WINDS WILL CONTINUE FROM THE CENTRAL PLAINS TO NORTHERN MINNESOTA,
ALONG WITH SOME SLEET AND FREEZING RAIN IN PARTS OF THE UPPER
MISSISSIPPI VALLEY. SNOW ACCUMULATING AT RATES OF 1-2"/HR IN
HEAVIER BANDS ARE EXPECTED FROM CENTRAL NEBRASKA AND EASTERN SOUTH
DAKOTA TO NORTHERN MINNESOTA. ADDITIONAL SNOWFALL TOTALS BETWEEN
6-12 INCHES ARE FORECAST FROM CENTRAL NEBRASKA TO NORTHEASTERN
MINNESOTA. HEAVY SNOW AND GUSTY WINDS APPROACHING 50 MPH WILL
PRODUCE BLIZZARD CONDITIONS WITH NEAR ZERO VISIBILITY INTO EARLY
TUESDAY. TRAVEL COULD BE NEARLY IMPOSSIBLE. POWER OUTAGES AND TREE
DAMAGE ARE LIKELY IN SOME AREAS DUE TO THE HEAVY AND WET SNOW
COMBINED WITH ICING AND STRONG WINDS. WINTER STORM/BLIZZARD
WARNINGS AND WINTER WEATHER ADVISORIES ARE IN EFFECT FROM PORTIONS
OF THE CENTRAL/SOUTHERN HIGH PLAINS TO THE UPPER MIDWEST.
IN THE WARM SECTOR OF THE WINTER STORM, SCATTERED RAIN SHOWERS AND
THUNDERSTORMS WILL SPREAD ACROSS THE MISSISSIPPI VALLEY AND
CENTRAL GULF COAST AHEAD OF A COLD FRONT TODAY. THERE'S AN
ENHANCED RISK OF SEVERE THUNDERSTORMS (LEVEL 2/5) TO OCCUR ACROSS
PORTIONS OF SOUTHEAST ARKANSAS INTO NORTHEAST LOUISIANA AND
CENTRAL MISSISSIPPI. TORNADOES AND DAMAGING WINDS ARE POSSIBLE
THROUGH TONIGHT FROM PARTS OF EAST TEXAS THROUGH THE LOWER
MISSISSIPPI VALLEY, ACCORDING TO THE STORM PREDICTION CENTER.
THERE'S ALSO A SLIGHT RISK (AT LEAST 15%) OF EXCESSIVE RAINFALL
LEADING TO FLASH FLOODING OVER PORTIONS OF SOUTHERN MISSOURI DOWN
THROUGH ARKANSAS, MISSISSIPPI AND WEST-CENTRAL ALABAMA. WHILE THE
SEVERE WEATHER THREAT WANES ON TUESDAY, THE EXCESSIVE RAINFALL
THREAT SIMPLY SHIFTS INTO THE SOUTHEAST. A SLIGHT RISK OF
EXCESSIVE RAINFALL IS IN EFFECT OVER PORTIONS OF SOUTHERN ALABAMA,
SOUTHWESTERN GEORGIA AND THE FLORIDA PANHANDLE ON TUESDAY, DUE, IN
PART, TO A STALLED OUT LOW PRESSURE SYSTEM ALONG THE GULF COAST.
STRONG WESTERLY FLOW ALONG THE BASE OF AN UPPER TROUGH WILL
SUPPORT VERY DRY AND GUSTY WINDS IN EXCESS OF 25 MPH OVER PORTIONS
OF THE SOUTHERN PLAINS TODAY. THUS THE STORM PREDICTION CENTER
ISSUED A CRITICAL FIRE WEATHER AREA (LEVEL 2/3) FOR FAR SOUTHERN
TEXAS. A FRIGID AIRMASS WILL SPILL OUT OVER THE GREAT PLAINS
TODAY, WHERE HIGH TEMPERATURE ANOMALIES WILL BE 15-30 DEGREES
BELOW AVERAGE. A MODERATING TEMPERATURE TREND BEGINS ON TUESDAY.
UNSETTLED WEATHER RETURNS TO THE PACIFIC NORTHWEST BY WEDNESDAY
THANKS TO A DEEP LOW PRESSURE SYSTEM.
