THE MID TO UPPER LEVEL FLOW WILL REMAIN HIGHLY AMPLIFIED ACROSS
THE LOWER 48 OVER THE NEXT SEVERAL DAYS, CONSISTING OF A DEEP
UPPER TROF MOVING INLAND FROM THE WEST COAST FRIDAY INTO THE GREAT
BASIN AND ROCKIES BY SATURDAY, A BUILDING UPPER RIDGE FROM THE
SOUTHERN PLAINS INTO THE OHIO VALLEY AND NORTHEAST, AND AN UPPER
LOW FORMING ACROSS THE NORTH CENTRAL GULF. THIS PATTERN WILL
SUPPORT A LARGE SPREAD IN TEMPERATURES FROM WEST TO EAST LATE THIS
WEEKEND. COOLER THAN AVERAGE TEMPERATURES ARE LIKELY FROM THE
WEST COAST THROUGH THE GREAT BASIN AND NORTHERN ROCKIES AS A
STRONG SURFACE COLD FRONT PUSHES INLAND WITH THE ABOVE MENTIONED
DEEP UPPER TROF. TO THE EAST OF THESE BELOW AVERAGE TEMPERATURES,
ABOVE TO MUCH ABOVE AVERAGE TEMPERATURES WILL STRETCH ACROSS MOST

TEMPERATURES FRIDAY AND SATURDAY ARE EXPECTED TO BE IN THE MID 80S
TO LOWER 90S, RANGING FROM 15 TO 30 DEGREES ABOVE AVERAGE. THIS
LATE SEASON HEATWAVE WILL PRODUCE MODERATE TO MAJOR HEAT RISKS
ACROSS THE DAKOTAS, MINNESOTA, NORTHERN IOWA, WESTERN WISCONSIN
INTO NORTHERN ILLINOIS. RELIEF FROM THIS HEAT WILL BEGIN LATE
THIS WEEKEND AS A STRONG FRONT PUSHES EASTWARD ACROSS THE NORTH
CENTRAL U.S.
THIS STRONG FRONT WILL FIRST MOVE THROUGH THE GREAT BASIN AND
NORTHERN ROCKIES REGION FRIDAY AND SATURDAY. THIS FRONT WILL
PRODUCE A STRIPE OF MODERATE TO HEAVY RAINS FROM THE NORTHERN
SIERRA, INTO THE NORTHERN GREAT BASIN AND NORTHERN ROCKIES REGION,
ALONG WITH THE POTENTIAL FOR ISOLATED FLOODING.
THE WETTEST WEATHER OVER THE NEXT FEW DAYS WILL BE ALONG THE EAST
COAST OF FLORIDA INTO THE COASTAL SOUTHEAST AND ALONG PORTIONS OF
THE CENTRAL GULF COAST. AN AREA OF SURFACE HIGH PRESSURE IS
FORECAST TO REMAIN CENTERED ACROSS THE NORTHEAST OVER THE NEXT FEW
DAYS. THE CLOCKWISE FLOW AROUND THIS HIGH WILL KEEP PERSISTENT
EASTERLY TO EAST NORTHEASTERLY LOW LEVEL FLOW OFF THE ATLANTIC AND
INTO FLORIDA, THE COASTAL SOUTHEAST AND THE CENTRAL GULF COAST.
THIS PATTERN WILL SUPPORT NUMEROUS SHOWERS ACROSS THESE AREAS,
WITH THE HEAVIEST RAINS LIKELY ALONG THE EAST COAST OF FLORIDA
FROM THURSDAY INTO SATURDAY. LOCALIZED FLOODING ISSUES ARE
POSSIBLE, ESPECIALLY IN THE URBAN AREAS ALONG THE EAST COAST OF
FLORIDA.
