...A DEEP LOW PRESSURE SYSTEM COULD CONTINUE TO CAUSE  
PRECIPITATION AND GUSTY WINDS IN NEW ENGLAND EARLY WEDNESDAY...  
 
...SEVERE THUNDERSTORMS POSSIBLE FOR THE SOUTHERN PLAINS TODAY AND  
THE LOWER MISSISSIPPI VALLEY ON THURSDAY...  
 
...CRITICAL RISK OF FIRE WEATHER FOR BOTH THE SOUTHERN HIGH PLAINS  
AND PARTS OF THE MID-ATLANTIC AND NORTHEAST...  
 
A STRONG LOW PRESSURE SYSTEM EAST OF THE ATLANTIC COAST WILL  
CONTINUE MOVING NORTHWARD TODAY INTO NOVA SCOTIA. ON THE BACKSIDE  
OF THE LOW, SOME LIGHT RAIN AND SNOW IS POSSIBLE IN NEW ENGLAND,  
PARTICULARLY ON WEDNESDAY MORNING. HIGH WINDS WILL ALSO BE A  
CONCERN DUE TO THE TIGHT PRESSURE GRADIENT FROM THE LOW, WITH  
HURRICANE FORCE WINDS ONGOING OVER OPEN WATER. THOUGH CERTAINLY  
WEAKER THAN HURRICANE FORCE, GUSTY WINDS ARE ALSO EXPECTED OVER  
THE MID-ATLANTIC AND NORTHEAST ON WEDNESDAY, AND WITH DRY AIR IN  
PLACE, FIRE DANGER IS LIKELY--RED FLAG WARNINGS ARE IN EFFECT AND  
THE STORM PREDICTION CENTER HAS OUTLOOKED A CRITICAL AREA OF FIRE  
WEATHER.  
 
AN UPPER-LEVEL TROUGH MOVING THROUGH THE FOUR CORNERS REGION ON  
WEDNESDAY, THE CENTRAL/SOUTHERN PLAINS WEDNESDAY NIGHT, AND THE  
MIDDLE/LOWER MISSISSIPPI VALLEY ON THURSDAY WILL CAUSE  
PRECIPITATION ACROSS THESE AREAS. A SLIGHT RISK OF SEVERE WEATHER  
IS IN PLACE FOR PARTS OF THE SOUTHERN PLAINS ON WEDNESDAY AHEAD OF  
A SURFACE LOW PRESSURE SYSTEM, AND AS THE LOW MOVES EASTWARD,  
SEVERE WEATHER IS EXPECTED FOR THE LOWER MISSISSIPPI VALLEY ON  
THURSDAY. LOCALLY HEAVY RAINFALL IS ALSO POSSIBLE ON THURSDAY  
ACROSS THE LOWER MISSISSIPPI VALLEY TO SOUTHEAST. FARTHER WEST,  
BEHIND A DRYLINE ASSOCIATED WITH THE LOW, A CRITICAL RISK OF FIRE  
WEATHER IS ALSO IN PLACE FOR THE SOUTHERN HIGH PLAINS. TO THE  
NORTH, RAIN AND SOME LIGHT SNOW WILL SPREAD ACROSS THE NORTHERN  
PLAINS TO UPPER/MIDDLE MISSISSIPPI VALLEY OVER THE NEXT COUPLE OF  
DAYS. PRECIPITATION TOTALS SHOULD BE ABOUT AN INCH OR LESS, BUT  
ANY PRECIPITATION THERE COULD EXACERBATE ONGOING FLOODING ACROSS  
THAT REGION. PRECIPITATION IS EXPECTED TO SHIFT EASTWARD INTO THE  
OHIO AND TENNESSEE VALLEYS ON THURSDAY AND INTO THE EASTERN  
SEABOARD BY FRIDAY MORNING.  
 
THE WESTERN U.S. IS EXPECTED TO BE WARM IN TERMS OF LOW  
TEMPERATURES ON WEDNESDAY, WITH SOME RECORD HIGH MINIMUM  
TEMPERATURES LIKELY TO BE TIED OR BROKEN. ADDITIONAL ENERGY  
APPROACHING THE WEST ON THURSDAY WILL LEAD TO INCREASING  
PRECIPITATION CHANCES (LOWER ELEVATION RAIN AND HIGHER ELEVATION  
SNOW) IN THE WEST COAST TO INTERMOUNTAIN WEST, PUSHING INTO THE  
ROCKIES BY FRIDAY MORNING.
