..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.
