000 FXUS01 KWBC 240722 PMDSPD SHORT RANGE FORECAST DISCUSSION NWS WEATHER PREDICTION CENTER COLLEGE PARK MD 321 AM EDT SUN SEP 24 2017 VALID 12Z SUN SEP 24 2017 - 12Z TUE SEP 26 2017 ...COLD FOR THE WESTERN U.S. AND WARM FOR THE EASTERN STATES... MUCH OF THE WESTERN U.S. WILL BE QUITE COOL INTO THE BEGINNING OF THE WORK WEEK AS A DEEP UPPER-LEVEL TROUGH CONTINUES TO DIG IN OVER THE WEST, AND BELOW NORMAL TEMPERATURES ARE FORECAST FOR MUCH OF THE REGION. A FEW AREAS ACROSS THE INTERMOUNTAIN WEST WILL HAVE LINGERING SNOW AT HIGHER ELEVATIONS INTO SUNDAY EVENING, OTHERWISE, MOSTLY DRY CONDITIONS ARE EXPECTED FOR THE VALLEYS AND LOWER TERRAIN. AT THE LEADING EDGE OF THIS TROUGH WILL BE A SLOW MOVING AND STRONG COLD FRONT WITH MULTIPLE WAVES OF LOW PRESSURE DEVELOPING ALONG IT FROM THE UPPER GREAT LAKES TO THE SOUTHERN ROCKIES. THE STRONG UPPER LEVEL RIDGE SITUATED OVER THE EASTERN HALF OF THE U.S. IS KEEPING THIS FRONT FROM MOVING FASTER. AS A RESULT SUMMER-LIKE HEAT AND NOTICEABLE LEVELS OF HUMIDITY WILL BE PRESENT FROM THE CENTRAL PLAINS TO THE EAST COAST THROUGH THE BEGINNING OF NEXT WEEK. SOME LOCATIONS COULD EVEN ACHIEVE RECORD HIGH TEMPERATURES WITH READINGS BREAKING THE 90-DEGREE MARK. WIDESPREAD AREAS WILL SEE TEMPERATURES RUNNING 10 TO 20 DEGREES ABOVE NORMAL FOR THIS TIME OF YEAR, MAKING IT FEEL MORE LIKE JULY AND AUGUST. NOW THAT THE REMNANT LOW FROM JOSE IS WEAKENING AND BECOMING A NON-ISSUE, OUR ATTENTION NOW TURNS TO HURRICANE MARIA AND ITS FUTURE TRACK NEAR PARTS OF THE EAST COAST FOR THE MIDDLE OF NEXT WEEK. CURRENT INDICATIONS SUGGEST THIS STORM MAY COME WITHIN 200 MILES OF NORTH CAROLINA`S OUTER BANKS BEFORE HEADING OUT TO SEA. IN THE MEANTIME, EXPECT ROUGH SURF AND HIGH SEAS FOR THE SOUTHEAST AND MID-ATLANTIC COASTS. THE NATIONAL HURRICANE CENTER HAS THE LATEST INFORMATION AND FORECAST TRACK REGARDING THIS HURRICANE.
