VALID 00Z MON APR 15 2019 - 00Z WED APR 17 2019  
 
...THE SEVERE WEATHER AND HEAVY RAINFALL THREAT CONTINUES INTO THE  
EAST TONIGHT...  
 
...UNSETTLED WEATHER OUT WEST WITH SNOWFALL ACCUMULATIONS POSSIBLE  
IN THE MOUNTAINS OF NORTHWEST WYOMING AND THE SIERRA NEVADA...  
 
THE SPRING STORM RESPONSIBLE FOR AN OUTBREAK OF SEVERE STORMS FROM  
EASTERN TEXAS TO THE SOUTHEAST THIS WEEKEND WILL CONTINUE MOVING  
EAST TONIGHT, AND OFF THE ATLANTIC COAST BY MONDAY MORNING. THE  
GREATEST THREAT TONIGHT FOR SEVERE WEATHER WILL BE ACROSS PARTS OF  
THE MID-ATLANTIC STATES WHERE THE STORM PREDICTION CENTER HAS AN  
ENHANCED RISK IN PLACE. THERE IS A SLIGHT RISK SOUTH OF THIS AREA  
ALONG THE COLD FRONT. LOCALLY HEAVY RAINFALL MAY ACCOMPANY THESE  
STORMS, WITH WPC HIGHLIGHTING A SLIGHT RISK FOR EXCESSIVE  
RAINFALL/FLASH FLOODING ACROSS PARTS OF THE APPALACHIANS INTO  
UPSTATE NEW YORK. THE COMBINATION OF WARM TEMPERATURES, RAIN, AND  
LINGERING SNOW COVER ACROSS PORTIONS OF NEW ENGLAND MAY ALSO LEAD  
TO A THREAT FOR RIVER FLOODING THROUGH TUESDAY MORNING.  
TEMPERATURES ON THE NORTH SIDE OF THIS SYSTEM SHOULD BE COLD  
ENOUGH TO SUPPORT LIGHT SNOW SHOWERS AND ACCUMULATIONS ACROSS  
PARTS OF LOWER MICHIGAN AND FAR NORTHERN MAINE TONIGHT.  
 
OUT WEST, UNSETTLED WEATHER WILL CONTINUE THROUGH MONDAY AS A COLD  
FRONT MOVES EASTWARD TOWARDS THE PLAINS TONIGHT. RAIN AND HIGHER  
ELEVATION SNOWS WILL ACCOMPANY THIS SYSTEM, ESPECIALLY ACROSS THE  
NORTHERN GREAT BASIN AND ROCKIES WITH MODERATE TO HEAVY SNOW  
ACCUMULATIONS POSSIBLE IN THE HIGHER ELEVATIONS OF WESTERN  
WYOMING. A SECOND SYSTEM APPROACHES THE COAST ON MONDAY, WHICH  
SHOULD BRING A RENEWED ROUND OF RAIN AND MOUNTAIN SNOWS TO  
CALIFORNIA, OREGON, AND THE GREAT BASIN FOR THE SECOND HALF OF  
MONDAY THROUGH TUESDAY. THE BEST CHANCE FOR ACCUMULATING SNOWFALL  
WILL BE IN THE SIERRA NEVADA WHERE UPWARDS OF A FOOT MAY BE  
POSSIBLE IN THE HIGHEST ELEVATIONS.  
 
BEHIND THE COLD FRONT IN THE EAST, TEMPERATURES ACROSS THE OHIO  
VALLEY AND INTO THE EAST SHOULD RETURN TO NEAR OR BELOW NORMAL BY  
MONDAY. MEANWHILE, ACROSS THE GREAT PLAINS, DAYTIME HIGHS ON  
MONDAY ARE FORECAST TO BE WELL INTO THE 80S, WHICH IS 10 TO 20  
DEGREES ABOVE AVERAGE. AND OUT WEST, BELOW AVERAGE TEMPERATURES  
SHOULD PERSIST THROUGH TUESDAY AS A SERIES OF COLD FRONTS MOVE  
THROUGH THE REGION.
