THE MID TO UPPER LEVEL FLOW CONTINUES TO AMPLIFY ACROSS THE CONUS,
LEADING TO AN ACTIVE WEATHER PATTERN ACROSS LARGE PORTIONS OF THE
EASTERN THIRD OF THE NATION. THE EASTERN COMPONENT OF THIS
AMPLIFYING FLOW WILL BE COMPRISED OF AN DEEPENING UPPER TROF FROM
THE GREAT LAKES INTO THE SOUTHEAST. THE ASSOCIATED AREA OF
SURFACE LOW PRESSURE FORECAST TO MOVE SLOWLY NORTHEAST FROM THE
SOUTHERN APPALACHIANS AND OFF THE MID-ATLANTIC COAST FRIDAY AND
SATURDAY WILL BRING INCREASINGLY STORMY WEATHER FROM THE
MID-ATLANTIC INTO NEW ENGLAND OVER THE NEXT 48 HOURS. SOME MUCH
NEEDED MODERATE TO HEAVY RAINS ARE POSSIBLE FROM THE MID-ATLANTIC
INTO SOUTHERN NEW ENGLAND WHERE WIDESPREAD MODERATE TO SEVERE
DROUGHT CONDITIONS EXIST. LATE SEASON ACCUMULATING SNOWS ALSO
POSSIBLE WITH THIS SYSTEM IN THE HIGHER ELEVATIONS FROM FAR
NORTHEAST PENNSYLVANIA, ACROSS NORTHWEST NEW JERSEY, NORTHERN AND
EASTERN NEW YORK STATE, AND WESTERN, CENTRAL AND NORTHERN NEW
ENGLAND.
SEVERE THUNDERSTORMS ARE POSSIBLE ALONG THE TRAILING COLD FRONT
PRESSING SOUTHEASTWARD THURSDAY EVENING INTO THURSDAY NIGHT ACROSS
THE LOWER OHIO VALLEY, TENNESSEE VALLEY AND INTO THE LOWER
MISSISSIPPI VALLEY AND SOUTH. THE GREATEST RISK FOR SEVERE
WEATHER ACROSS THESE REGIONS WILL BE FROM HIGH WINDS AND LARGE
HAIL, WITH A LESSER THREAT OF TORNADOES.
WHILE THE OVERALL AMPLIFIED FLOW ACROSS THE CONUS IS LEADING TO
STORMY WEATHER ACROSS LARGE PORTIONS OF THE EAST, THE WESTERN
COMPONENT OF THIS AMPLIFIED PATTERN WILL SUPPORT MUCH ABOVE
AVERAGE TO RECORD WARMTH ACROSS LARGE PORTIONS OF THE WESTERN AND
CENTRAL U.S. RECORD HIGH TEMPERATURES ARE POSSIBLE FRIDAY FROM
THE SOUTHWEST INTO THE GREAT BASIN AND ACROSS THE SOUTHWEST INTO
THE CENTRAL TO SOUTHERN HIGH PLAINS ON SATURDAY. SOME COOLING TO
THE WIDESPREAD MUCH ABOVE AVERAGE WESTERN TEMPERATURES SET FOR THE
PACIFIC NORTHWEST INTO THE NORTHERN ROCKIES WHERE HIGH
TEMPERATURES ARE FORECAST TO FALL TO SLIGHTLY BELOW AVERAGE FRIDAY
AND SATURDAY IN THE WAKE OF A COLD FRONT PUSHING OFF THE NORTHEAST
PACIFIC AND INLAND ACROSS THE NORTHWEST.
WARM TEMPERATURES, LOW RELATIVE HUMIDITIES AND WINDY CONDITIONS
EXPECTED TO SPREAD INTO THE CENTRAL TO NORTHERN PLAINS OVER THE
NEXT TWO DAYS. THIS WILL INCREASE THE RISK OF WILD FIRES ACROSS
THESE AREAS. RED FLAG WARNINGS ARE CURRENTLY IN EFFECT ACROSS
MUCH OF SOUTH DAKOTA, NEBRASKA INTO NORTHWEST KANSAS, AFFECTING
APPROXIMATELY 2 MILLION PEOPLE. WINDS ARE ALSO EXPECTED TO
STRENGTHEN SATURDAY ACROSS FLORIDA IN THE WAKE OF THE ABOVE
MENTIONED COLD FRONT SINKING SOUTHEAST. THESE INCREASINGLY WINDY
CONDITIONS AND LOWERING RELATIVE HUMIDITIES WILL ALSO INCREASE THE
FIRE WEATHER RISK FOR CENTRAL FLORIDA ON SATURDAY.
