BEFORE WINTRY PRECIPITATION DEVELOPS OVER THE CENTRAL PLAINS ON
SUNDAY...
...SHOWERS AND THUNDERSTORMS WILL MOVE OFF THE SOUTHEAST U.S.
COAST TONIGHT BUT THEY WILL LINGER INTO THE WEEKEND FOR THE

THE WEATHER PATTERN ACROSS THE U.S. WILL SUPPORT A LARGE CONTRAST
IN TEMPERATURES ACROSS THE U.S. AS A WARM RIDGE OF HIGH PRESSURE
WILL KEEP WELL ABOVE NORMAL TEMPERATURES IN THE SOUTHWEST WHILE AN
OUTBREAK OF ARCTIC AIR WILL SURGE ACROSS THE NORTHERN TIER STATES.
IN FACT, RECORD BREAKING TEMPERATURES TOPPING NEAR 100 DEGREES
ARE FORECAST NEAR THE SOUTHERN BORDER OF THE DESERT SOUTHWEST
SATURDAY AFTERNOON UNDER THE RIDGE, INCLUDING HIGH TEMPERATURES
WELL UP INTO THE 80S FOR LOS ANGELES. TEMPERATURES WILL BEGIN TO
MODERATE ON SUNDAY BUT THEY WILL REMAIN AT RECORD HIGH LEVELS
SUNDAY AFTERNOON ACROSS THE SOUTHWEST. MEANWHILE, AN OUTBREAK OF
ARCTIC AIR CURRENTLY REACHING INTO THE NORTHERN PLAINS WILL SURGE
EAST ACROSS THE NORTHERN TIER STATES WHILE SPREADING FARTHER SOUTH
INTO THE CENTRAL PLAINS OVER THE WEEKEND. A SWATH OF LIGHT TO
LOCALLY MODERATE SNOW WILL MOVE QUICKLY ACROSS THE NORTHERN TIER
STATES FROM WEST TO EAST THROUGH THE NEXT COUPLE OF DAYS REACHING
NEW ENGLAND ON SUNDAY WELL BEHIND THE ARCTIC FRONT. BY SUNDAY
AFTERNOON, WINTRY PRECIPITATION IS FORECAST TO EMERGE OVER THE
CENTRAL PLAINS AS AN UPPER-LEVEL SHORTWAVE EJECTING OUT OF THE
CENTRAL ROCKIES BEGINS TO INTERACT WITH THE ARCTIC FRONT.
MEANWHILE, RAIN IS FORECAST FARTHER SOUTH ACROSS THE SOUTH-CENTRAL
PLAINS.
ACROSS THE SOUTHEAST, A FRONTAL SYSTEM WITH MULTIPLE LOW PRESSURE
WAVES WILL GRADUALLY SLIDE EAST INTO THE ATLANTIC TONIGHT.
SHOWERS AND THUNDERSTORMS BEHIND THE SYSTEM WILL BE MOVING OFF THE
SOUTHEAST U.S. INTO THE ATLANTIC BUT THE TRAILING PORTION OF THE
FRONT WILL TAKE ADDITIONAL TIME TO MOVE THROUGH THE FLORIDA
PENINSULA, KEEPING THE CHANCE OF SHOWERS AND THUNDERSTORMS INTO
THE WEEKEND FOR THIS PORTION OF THE SUNSHINE STATE. FOR THE WEST
COAST, AN UPPER-LEVEL TROUGH MOVING ONSHORE WILL PRODUCE SCATTERED
RAIN AND RAIN SHOWERS FROM NORTHERN CALIFORNIA TO THE GREAT BASIN
DURING THE WEEKEND.
