...HEAVY RAIN AND FLASH FLOODING POSSIBLE ACROSS THE WESTERN GULF  
COASTAL REGION AND ACROSS COASTAL WASHINGTON, OREGON AND NORTHWEST  
CALIFORNIA...  
   
..WILD FIRE THREAT ACROSS THE CENTRAL AND SOUTHERN PLAINS  
 
...MUCH ABOVE AVERAGE TEMPERATURES FROM THE ROCKIES, EAST TO THE  
EAST COAST, WHILE MUCH COOLER AIR SETTLES SOUTH INTO THE NORTHERN  
PLAINS, UPPER LAKES INTO NORTHERN NEW ENGLAND...  
 
...WINTER WEATHER WITH HEAVY SNOW POSSIBLE FOR NORTHERN NEW  
ENGLAND AND PORTIONS OF THE CENTRAL TO NORTHERN PLAINS TOWARD THE  
UPPER MISSISSIPPI VALLEY/UPPER GREAT LAKES...  
 
THERE IS A WIDE VARIETY OF WEATHER HAZARDS EXPECTED ACROSS THE  
LOWER 48 AS THE WORK WEEK ENDS AND THE WEEKEND BEGINS. A SLOW  
MOVING MID TO UPPER LEVEL LOW MOVING ACROSS NORTHERN MEXICO AND  
INTO THE SOUTHERN PLAINS WILL FOCUS A HEAVY RAIN AND FLASH FLOOD  
THREAT ACROSS AREAS FROM SOUTH AND EAST TEXAS INTO SOUTHERN  
LOUISIANA. THERE IS EXPECTED TO BE ROUNDS OF THUNDERSTORMS AND  
HEAVY RAINS FROM THURSDAY AFTERNOON/ THURSDAY NIGHT INTO FRIDAY  
ACROSS THESE AREAS WHERE ATMOSPHERIC MOISTURE VALUES ARE FORECAST  
TO REMAIN WELL ABOVE AVERAGE. AREAS OF SOUTH TEXAS HAVE ALREADY  
RECEIVED RAINFALL TOTALS RANGING FROM 2 TO OVER 7 INCHES IN THE  
PAST 24 HOURS. THE ADDITIONAL ROUNDS OF THUNDERSTORMS WILL POSE  
AN INCREASING FLOOD AND FLASH FLOOD RISK, ESPECIALLY OVER AREAS  
THAT SEE REPEAT ROUNDS OF HEAVY RAINS.  
 
HEAVY RAIN IS ALSO POSSIBLE ALONG COASTAL PORTIONS OF WASHINGTON  
STATE, OREGON AND NORTHWEST CALIFORNIA FROM THURSDAY AFTERNOON  
INTO FRIDAY AS A SLOW MOVING AREA OF LOW PRESSURE MEANDERS OFF THE  
PACIFIC NORTHWEST COAST. THIS ADDITIONAL RAINFALL WILL NOT HAVE  
THE SEVERE POTENTIAL THAT THE RAINS OF THE PAST 24 HOURS DID FOR  
THE PACIFIC NORTHWEST, BUT THERE WILL BE A LOW END RISK OF  
FLOODING. THE AREA OF LOW PRESSURE OFF THE PACIFIC NORTHWEST  
COAST AND THE ASSOCIATED COLD FRONT THAT HAS MOVED INLAND, WILL BE  
BRINGING MUCH COOLER CONDITIONS FOR THE NORTHWEST COMPARED TO THE  
PAST FEW DAYS, WHICH SAW MUCH ABOVE AND RECORD HIGH TEMPERATURES.  
 
WHILE TEMPERATURES COOL ACROSS THE NORTHWEST OVER THE NEXT TWO  
DAYS, MUCH ABOVE AVERAGE TEMPERATURES WILL PUSH EASTWARD FROM THE  
ROCKIES/PLAINS REGION THURSDAY, EASTWARD TO LARGE SECTIONS OF THE  
EAST COAST FRIDAY INTO SATURDAY. THIS WILL BE A WARMING TREND FOR  
LARGE SECTIONS OF THE EAST FROM THE LOWER LAKES, OHIO VALLEY,  
CENTRAL TO SOUTHERN APPALACHIANS AND MID-ATLANTIC WHICH HAVE SEEN  
BELOW AVERAGE TEMPERATURES OVER THE PAST FEW DAYS.  
 
THE EXCEPTION TO THE ABOVE WARMING TREND, WILL BE ALONG THE  
NORTHERN TIER OF THE LOWER 48 FROM THE NORTHERN PLAINS, ACROSS THE  
UPPER LAKES AND INTO FAR NORTHERN NEW YORK STATE AND NORTHERN NEW  
ENGLAND. A STRONG FRONT ORIENTED FROM WEST TO EAST ACROSS THESE  
REGIONS WILL SEPARATE THE MUCH ABOVE AVERAGE TEMPERATURES TO THE  
SOUTH OF THIS FRONT FROM THE BELOW AVERAGE TEMPERATURES TO ITS  
NORTH. WINTER WEATHER IS POSSIBLE ON THE COLD SIDE OF THIS FRONT,  
WITH ACCUMULATING SNOWS POSSIBLE FROM FAR NORTHERN NEW YORK STATE,  
ACROSS NORTHERN VERMONT, NORTHERN NEW HAMPSHIRE AND SOUTHWEST  
MAINE. THIS WILL BE FOLLOWED BY ANOTHER AREA OF ACCUMULATING SNOW  
POTENTIAL SATURDAY INTO SUNDAY FROM THE CENTRAL TO NORTHERN PLAINS  
TOWARD THE UPPER MISSISSIPPI VALLEY AND UPPER LAKES REGION.  
 
TO THE SOUTH OF THE WINTER WEATHER AREAS ACROSS THE CENTRAL TO  
NORTHERN PLAINS, WINDY,WARM AND DRY CONDITIONS WILL CONTINUE  
ACROSS THE REMAINDER OF THE CENTRAL TO SOUTHERN PLAINS, SAVE FOR  
THE WET WEATHER ACROSS SOUTH TEXAS. THESE CONDITIONS WILL  
CONTINUE TO SUPPORT A WILD FIRE RISK ACROSS THESE AREAS OVER THE  
NEXT FEW DAYS.
