...HEAVY RAIN AND WIND EXPECTED FOR FLORIDA AND THE SOUTHEAST
COAST...

...COOLER AND DRIER CONDITIONS ARRIVING BEHIND COLD FRONT...

THE BIG STORY MAKING WEATHER HEADLINES THROUGH THE END OF THE WEEK
WILL BE THE TROPICS AND THE TRACK OF WHAT IS NOW TROPICAL
DEPRESSION #9.  THIS SYSTEM IS FORECAST TO INTENSIFY INTO A
TROPICAL STORM (HERMINE IS THE NEXT NAME ON THE LIST) SOON AND
HEAD TOWARDS NORTHERN FLORIDA AND THEN PARALLEL THE SOUTHEAST
COAST BEFORE EVENTUALLY HEADING OUT TO SEA.  SEVERAL INCHES OF
RAINFALL IS LIKELY ALONG AND JUST SOUTH OF THE STORM TRACK, AND
STRONG GUSTY WINDS WILL ALSO BE PROBLEMATIC NEAR THE COAST.  THE
RAIN MAY BE HEAVY ENOUGH TO CAUSE FLOODING ISSUES, ESPECIALLY OVER
PARTS OF FLORIDA AND GEORGIA.

FARTHER TO THE NORTHWEST, A COLD FRONT WILL BE USHERING IN A
QUALITY AIRMASS THAT WILL BRING MORE PLEASANT TEMPERATURES AND
LOWER HUMIDITY FROM THE MIDWEST STATES TO THE MID-ATLANTIC REGION.
 THIS FRONT SHOULD REACH THE EAST COAST AROUND THURSDAY MORNING,
AND THIS WILL HELP STEER THE TROPICAL STORM IN A NORTHEAST
DIRECTION AND OUT TO THE ATLANTIC OCEAN.  THIS FRONT IS EXPECTED
TO STALL BEFORE REACHING THE DEEP SOUTH, WHERE LATE-SUMMER HEAT
AND HUMIDITY WILL CONTINUE.

ACROSS THE WESTERN U.S., ANOTHER FRONTAL BOUNDARY WILL SLOWLY MAKE
ITS WAY ACROSS THE GREAT BASIN AND NORTHERN ROCKIES.  THIS FRONT
IS IN RESPONSE TO AN UPPER LEVEL TROUGH OVER THE NORTHWESTERN U.S.
 SCATTERED SHOWERS AND STORMS ARE LIKELY TO DEVELOP EACH AFTERNOON
ACROSS THE CENTRAL AND SOUTHERN ROCKIES WITH MONSOONAL MOISTURE
STILL IN PLACE.  SHOWERS ARE ALSO EXPECTED ACROSS WESTERN
WASHINGTON AND OREGON OWING TO ONSHORE FLOW.
