...HURRICANE MARIA TO CONTINUE TRACKING NORTH OFFSHORE THE
SOUTHERN MID-ATLANTIC COAST...

...COLDER TEMPERATURES WILL PERSIST ACROSS THE WESTERN STATES AND
WARMER ACROSS THE EASTERN STATES...

...SNOW IN THE HIGHER ELEVATIONS OF THE CENTRAL ROCKIES...

WIDESPREAD, COOLER THAN AVERAGE TEMPERATURES WILL CONTINUE FOR
MUCH OF THE WEST FOR A FEW MORE DAYS BEFORE RETURNING TO NEAR
SEASONAL NORMAL BY THE END OF THE WEEK. HIGH PRESSURE IS FORECAST
TO BUILD OVER THE INTERMOUNTAIN WEST, HIGH PLAINS,
NORTHERN/CENTRAL PLAINS AND THE MIDWEST. THIS WILL REDUCE OR LIMIT
ANY PRECIPITATION ALONG THE WEST COAST, GREAT BASIN AND THE
NORTHERN ROCKIES. SNOW, POSSIBLY HEAVY AT TIMES WILL BE POSSIBLE
THROUGH WEDNESDAY FOR THE CENTRAL ROCKIES. FOR THE EAST, WARMER
TEMPERATURES WILL REMAIN AS THE RIDGE STAYS ANCHORED IN PLACE
THROUGH MIDWEEK. SOME LOCATIONS COULD EVEN ACHIEVE RECORD HIGH
TEMPERATURES WITH READINGS BREAKING THE 90-DEGREE MARK.

A STRONG, SLOW MOVING COLD FRONT WITH MULTIPLE WAVES OF LOW
PRESSURE DEVELOPING ALONG IT WILL SPAN FROM THE UPPER GREAT LAKES
TO TEXAS. NUMEROUS TO WIDESPREAD SHOWERS AND THUNDERSTORMS WILL
DEVELOP ALONG THIS BOUNDARY, ESPECIALLY OVER THE SOUTHERN
ROCKIES/ADJACENT HIGH PLAINS. WITH SLOW MOTION AND AMPLE AVAILABLE
MOISTURE STREAMING IN ASSOCIATION WITH TROPICAL DEPRESSION PILAR,
THERE WILL LIKELY BE PERIODS OF HEAVY RAINFALL, WHICH MAY LEAD TO
SOME FLOODING ISSUES FROM TEXAS TO THE UPPER MIDWEST. MUCH OF
WESTERN TEXAS HAS A SLIGHT TO MODERATE RISK FOR EXCESSIVE
RAINFALL-- THIS AREA HAS FORECAST 3-DAY MAXIMUMS OF 5 TO 10 INCHES
FROM WEST-CENTRAL TEXAS TO EDWARDS PLATEAU.

HURRICANE MARIA IS FORECAST TO TRACK NEAR PARTS OF THE EAST COAST
ON TONIGHT AND INTO WEDNESDAY.  CURRENT INDICATIONS SUGGEST THIS
STORM MAY COME WITHIN 200 MILES OF NORTH CAROLINA`S OUTER BANKS
BEFORE HEADING OUT TO SEA ON THURSDAY.  IT WILL BE THE FRONT
APPROACHING FROM THE WEST THAT CAUSES THE EASTWARD TURN FOR THE
HURRICANE LATER IN THE WEEK.  IN THE MEANTIME, EXPECT ROUGH SURF
AND HIGH SEAS FOR THE SOUTHEAST AND MID-ATLANTIC COASTS, ALONG
WITH INCREASING CLOUDINESS AND GUSTY WINDS.  THE NATIONAL
HURRICANE CENTER HAS THE LATEST INFORMATION AND FORECAST TRACK
REGARDING THIS HURRICANE.
