...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.
