...HEAVY RAIN POSSIBLE OVER PORTIONS OF FLORIDA...

...ABOVE AVERAGE TEMPERATURES EXPECTED FOR MUCH OF THE CENTRAL AND
EASTERN U.S...

A WEAK TROUGH OF LOW PRESSURE ASSOCIATED WITH THE REMNANTS OF
ERIKA WILL BRING SHOWERS AND THUNDERSTORMS TO PORTIONS OF FLORIDA
OVER THE NEXT COUPLE DAYS. A VERY MOIST AND UNSTABLE ATMOSPHERE IN
PLACE WILL RESULT IN THE POTENTIAL FOR LOCALLY HEAVY RAINFALL.

A PACIFIC COLD FRONT WILL MOVE INLAND ACROSS THE WESTERN U.S.
TONIGHT INTO WEDNESDAY. ONSHORE FLOW IN THE WAKE OF THE FRONT WILL
BRING NUMEROUS RAIN SHOWERS AND A FEW THUNDERSTORMS TO COASTAL
PORTIONS OF THE PACIFIC NORTHWEST THROUGH WEDNESDAY. SHOWERS AND
THUNDERSTORMS WILL ALSO BE POSSIBLE ON WEDNESDAY IN ASSOCIATION
WITH THIS SYSTEM ACROSS NORTHERN PORTIONS OF THE INTERMOUNTAIN
WEST. ELSEWHERE ACROSS THE WEST, SCATTERED AFTERNOON AND EVENING
SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE THROUGH THURSDAY ACROSS
THE FOUR CORNERS REGION AS MONSOONAL MOISTURE REMAINS IN PLACE.

HIGH PRESSURE AT THE MID AND UPPER-LEVELS OF THE ATMOSPHERE WILL
RESULT A SINKING AND WARM AIR MASS ACROSS MUCH OF THE CENTRAL AND
EASTERN U.S. TEMPERATURES WILL BE ABOVE AVERAGE, WITH AFTERNOON
HIGH TEMPERATURES 5 TO 15 DEGREES ABOVE AVERAGE THROUGH THURSDAY,
PARTICULARLY FROM THE NORTHERN PLAINS AND MIDWEST EASTWARD TO
PORTIONS OF THE NORTHEAST AND MID-ATLANTIC REGIONS.
