THERE ARE THREE STORM SYSTEMS THAT ARE AND/OR WILL BE IMPACTING  
THE CONUS OVER THE NEXT FEW DAYS. THE FIRST OF THE THREE IS THE  
MAJOR WINTER STORM BRINGING HEAVY SNOW AND STRONG WINDS TO THE  
NORTHEAST AND CENTRAL APPALACHIANS TODAY. ADDITIONAL SNOWFALL OF  
4-8 INCHES ARE EXPECTED FOR MUCH OF THE AFOREMENTIONED AREAS  
THROUGH TONIGHT WHEN THE STORM IS EXPECTED TO PULL AWAY INTO THE  
ATLANTIC. WINTER STORM WARNINGS AND WINTER WEATHER ADVISORIES ARE  
IN EFFECT. CONDITIONS SHOULD IMPROVE ON MONDAY.  
 
THE SECOND STORM SYSTEM IS ONE THAT WILL MAKE ITS WAY THROUGH THE  
ROCKIES TODAY. HEAVY SNOW IS LIKELY ACROSS MUCH OF THE  
INTERMOUNTAIN WEST AND CENTRAL/SOUTHERN ROCKIES. SNOW IS ALSO  
LIKELY OVER THE NORTHERN ROCKIES BUT TO A LESSER EXTENT. THIS  
SYSTEM WILL REORGANIZE OVER THE SOUTHERN PLAINS ON MONDAY AND  
DEVELOP INTO A DEEP AND DYNAMIC MID-LATITUDE CYCLONE. THIS STORM  
WILL GENERATE HEAVY SNOW AND STRONG WINDS OVER THE PLAINS AND  
MIDWEST ON MONDAY AND TUESDAY. THE HEAVIEST SNOW TOTALS ARE MOST  
LIKELY IN PARTS OF THE MIDWEST, WHERE LOCAL MAXIMA UP TO 12 INCHES  
ARE LIKELY. BLIZZARD CONDITIONS ARE MOST LIKELY IN THE CENTRAL  
PLAINS WHERE WIND GUSTS IN EXCESS OF 50 MPH WILL LEAD TO NEAR ZERO  
VISIBILITY AT TIMES AND EXTREMELY DANGEROUS TRAVEL. BLIZZARD  
CONDITIONS ARE POSSIBLE IN THE MIDWEST AS WELL. WINTER STORM  
WATCHES ARE IN EFFECT FOR PARTS OF THE SOUTHERN HIGH PLAINS,  
CENTRAL PLAINS AND MIDDLE MISSISSIPPI VALLEY.  
 
WIDESPREAD AND POTENTIALLY SIGNIFICANT RIVER AND FLASH FLOODING  
ARE LIKELY FROM THE CENTRAL GULF COAST THROUGH MUCH OF THE EASTERN  
U.S. EARLY THIS WEEK. POWERFUL ONSHORE WINDS WILL LEAD TO  
WIDESPREAD COASTAL FLOODING ALONG THE EASTERN GULF COAST AND MUCH  
OF THE EAST COAST. SIGNIFICANT COASTAL FLOODING IS LIKELY IN SOME  
AREAS, ESPECIALLY IN THE CAROLINAS AND MID-ATLANTIC. THERE IS A  
SLIGHT RISK OF EXCESSIVE RAINFALL LEADING TO FLASH FLOODING FOR  
PORTIONS OF THE GULF COAST. STORMS WILL SUPPORT 1.5 TO 2.5 INCH/HR  
RAIN RATES WITH LOCALIZED AMOUNTS OF 4 TO 6 INCHES POSSIBLE. THERE  
IS A SLIGHT RISK OF SEVERE THUNDERSTORMS MONDAY THROUGH MONDAY  
NIGHT ACROSS PARTS OF SOUTHEAST TEXAS, SOUTHERN LOUISIANA,  
SOUTHERN MISSISSIPPI, SOUTHERN ALABAMA INTO THE WESTERN FLORIDA  
PANHANDLE. DAMAGING WIND GUSTS AND TORNADOES ARE POSSIBLE ACROSS  
THOSE AREAS BY LATE MONDAY NIGHT. WIDESPREAD WIND GUSTS IN EXCESS  
OF 50 MPH ARE LIKELY IN THE EASTERN GULF COAST SO PREPARE FOR  
POWER OUTAGES.  
 
THE THIRD SYSTEM ARRIVES OVER THE PACIFIC NORTHWEST TONIGHT. A  
DEEP PACIFIC STORM SYSTEM WILL GENERATE HEAVY COASTAL RAIN, HEAVY  
MOUNTAIN SNOW AND STRONG WINDS ACROSS THE REGION BEGINNING TONIGHT  
AND CONTINUING THROUGH AT LEAST MIDWEEK. THIS MAJOR WINTER STORM  
WILL BRING SEVERAL FEET OF SNOW TO THE WASHINGTON AND OREGON  
CASCADES AND WILL PEAK ON TUESDAY AND WEDNESDAY.
