...UNSETTLED WEATHER, INCLUDING MOUNTAIN SNOWS TO CONTINUE ACROSS  
THE NORTHWEST AND NORTHERN ROCKIES...  
 
...STRONG GUSTY WINDS FOR PORTIONS OF THE OHIO VALLEY INTO THE  
CENTRAL AND SOUTHERN APPALACHIANS SUNDAY EVENING...  
 
A FRONTAL SYSTEM WILL CONTINUE TO PUSH SOUTHEAST ACROSS THE  
NORTHWESTERN U.S., BRINGING LOCALLY HEAVY PRECIPITATION AND LOWER  
SNOW LEVELS TO THE NORTHERN ROCKIES SUNDAY EVENING. EVEN WITH THE  
FRONT MOVING WELL TO THE EAST, EASTERLY WINDS WILL CONTINUE TO  
SUPPORT SHOWERS ACROSS WESTERN WASHINGTON AND OREGON, AS WELL AS  
THE NORTHERN ROCKIES THROUGH TUESDAY. NEAR TO BELOW-NORMAL  
TEMPERATURES WILL EXTEND EAST FROM THE NORTHWEST INTO THE NORTHERN  
GREAT BASIN AND ROCKIES ON MONDAY, BEFORE SPREADING ACROSS THE  
CENTRAL ROCKIES INTO THE HIGH PLAINS ON TUESDAY. DRY CONDITIONS  
WILL PERSIST ACROSS MUCH OF CALIFORNIA AND THE GREAT BASIN.  
ELEVATED FIRE WEATHER CONDITIONS TODAY ALONG THE SIERRA FRONT WILL  
BE FOLLOWED BY ELEVATED CONDITIONS ACROSS PORTIONS OF SOUTHERN  
CALIFORNIA ON MONDAY.  
 
AS THE FRONT MOVES OUT INTO THE PLAINS AND MIDWEST, SHOWERS AND  
THUNDERSTORMS ARE FORECAST TO DEVELOP FROM THE GREAT LAKES BACK  
THROUGH THE MID MISSISSIPPI VALLEY INTO THE SOUTHERN PLAINS ON  
TUESDAY, WITH HEAVY SNOWS BEGINNING TO DEVELOP BY LATE TUESDAY  
ACROSS THE COLORADO INTO THE NORTHERN NEW MEXICO MOUNTAINS.  
 
FURTHER EAST, RAIN WITH SCATTERED THUNDERSTORMS WILL ACCOMPANY A  
FAST MOVING LOW PRESSURE SYSTEM AS IT MOVES THROUGH THE OHIO  
VALLEY SUNDAY EVENING, INTO THE NORTHEAST AND THROUGH THE  
MID-ATLANTIC OVERNIGHT. THIS SYSTEM IS EXPECTED TO BRING A SURGE  
OF GUSTY WINDS AS IT MOVES ACROSS THE REGION. THESE WINDS MAY  
CONTINUE TO STRENGTHEN AND REMAIN GUSTY THROUGH MONDAY MORNING,  
ESPECIALLY ACROSS THE HIGHER TERRAIN. WIND ADVISORIES ARE IN  
EFFECT THROUGH THE OVERNIGHT HOURS INTO EARLY MONDAY FOR PORTIONS  
OF THE CENTRAL AND SOUTHERN APPALACHIANS.
