VALLEYS THROUGH THURSDAY...

A STRONG, SLOW-MOVING LOW PRESSURE SYSTEM WILL MOVE FROM THE  
SOUTHWEST ACROSS THE CENTRAL AND SOUTHERN ROCKIES TONIGHT.  
STRONG, SOUTHERLY WINDS AHEAD OF THE SYSTEM WILL TAP MOIST,  
UNSTABLE AIR -- SUPPORTING WIDESPREAD SHOWERS AND THUNDERSTORMS  
THAT WILL DEVELOP AND SPREAD EAST FROM THE SOUTHERN AND CENTRAL  
PLAINS INTO THE MISSISSIPPI VALLEY. A FEW STRONG TO SEVERE  
STORMS, PRODUCING DAMAGING WINDS AND PERHAPS A TORNADO, ARE  
POSSIBLE TONIGHT FROM CENTRAL TEXAS TO FAR SOUTHERN OKLAHOMA. IN  
ADDITION TO SEVERE WEATHER, AREAS OF HEAVY RAINFALL AND LOCALIZED  
FLOODING ARE POSSIBLE AS WELL FROM PORTIONS OF NORTHEASTERN TEXAS  
TO WESTERN ARKANSAS. COLD AIR ON THE BACKSIDE OF THE SYSTEM WILL  
SUPPORT SNOW ACROSS PARTS OF THE SOUTHERN ROCKIES, WITH  
ACCUMULATIONS OF UP TO A FOOT POSSIBLE OVER THE HIGHER ELEVATIONS  
OF THE NORTHERN NEW MEXICO RANGES.  
 
THE SYSTEM WILL BEGIN TO MOVE MORE STEADILY TO THE EAST ON  
THURSDAY, BRINGING SHOWERS AND STORMS AND THE THREAT FOR SEVERE  
WEATHER FARTHER EAST AS WELL. STRONG, ISOLATED SEVERE STORMS,  
PRODUCING DAMAGING WIND AND HAIL, WILL BE POSSIBLE FROM EASTERN  
TEXAS THROUGH THE LOWER MISSISSIPPI VALLEY. THE THREAT FOR HEAVY  
RAIN AND FLASH FLOODING WILL EXTEND FARTHER NORTHEAST FROM  
NORTHEASTERN TEXAS INTO THE LOWER OHIO VALLEY.  
 
BY LATE FRIDAY, THE STORM WILL BEGIN TO WEAKEN AS IT MOVES QUICKLY  
INTO THE EASTERN U.S. WIDESPREAD PRECIPITATION IS EXPECTED ACROSS  
THE EASTERN-THIRD OF THE CONUS. HOWEVER, THE THREAT FOR SEVERE  
WEATHER WILL LIKELY BE CONFINED TO THE CENTRAL AND EASTERN GULF  
COAST, WITH WIDESPREAD HEAVY RAINFALL NOT EXPECTED. ACCUMULATING  
SNOWFALL WILL BE LIMITED AS WELL. LACKING COLD AIR, THIS STORM IS  
EXPECTED TO PRODUCE ONLY SOME MINOR ACCUMULATIONS NORTH OF THE LOW  
TRACK AS IT MOVES INTO THE NORTHEAST ON FRIDAY.  
 
DRY CONDITIONS WILL CONTINUE ACROSS THE WESTERN U.S. UNTIL LATE  
THURSDAY WHEN A FRONTAL SYSTEM BEGINS TO IMPACT THE NORTHWEST.  
WIDESPREAD PRECIPITATION, INCLUDING HEAVY MOUNTAIN SNOW, WILL  
BEGIN TO SPREAD EAST ACROSS THE NORTHWEST INTO THE NORTHERN  
ROCKIES AND SOUTH INTO NORTHERN CALIFORNIA, THURSDAY NIGHT.  
PRECIPITATION WILL CONTINUE TO SPREAD FARTHER SOUTH AND EAST ON  
FRIDAY, WITH HEAVY SNOW ACCUMULATIONS LIKELY ACROSS OLYMPICS, AND  
PORTIONS OF THE CASCADES, AND THE NORTHERN ROCKIES.  
 
APART FROM SOME BELOW-AVERAGE TEMPERATURES BEHIND A COLD FRONT  
SINKING SOUTH ACROSS THE NORTHEAST, TEMPERATURES WILL BE WELL  
ABOVE NORMAL ACROSS THE CENTRAL AND EASTERN U.S. ON THURSDAY.  
DAYTIME TEMPERATURE TOPPING OUT IN THE LOWER 40S TO UPPER 50S ARE  
EXPECTED TO SET NEW DAILY RECORDS ACROSS PORTIONS OF SOUTHERN  
MINNESOTA, WISCONSIN, AND NORTHERN ILLINOIS. ABOVE-NORMAL  
TEMPERATURES ARE THEN FORECAST TO SPREAD ACROSS THE REMAINDER OF  
THE EASTERN U.S. ON FRIDAY. FOLLOWING A CHILLY START,  
TEMPERATURES ARE EXPECTED TO MODERATE ACROSS THE SOUTHWEST AND THE  
SOUTHERN ROCKIES THROUGH THE LATTER HALF OF THE WEEK. ELSEWHERE  
IN THE WEST, TEMPERATURES WILL REMAIN NEAR SEASONAL TO  
ABOVE-NORMAL FOR MANY LOCATIONS.
