...THERE IS A SLIGHT RISK OF EXCESSIVE RAINFALL OVER PARTS OF
SOUTHEASTERN FLORIDA...
A FRONT WILL BE LINGERING OVER FLORIDA THROUGH FRIDAY. TROPICAL
MOISTURE WILL POOL OVER FLORIDA AND THE CENTRAL GULF COAST, AIDING
IN THE DEVELOPMENT OF SHOWERS AND THUNDERSTORMS THAT WILL BRING
HEAVY RAIN TO FLORIDA AND ALONG THE CENTRAL GULF COAST. THEREFORE,
THE WPC HAS ISSUED A SLIGHT RISK (LEVEL 2/4) OF EXCESSIVE RAINFALL
OVER SOUTHEASTERN FLORIDA THROUGH THURSDAY MORNING. THE
ASSOCIATED HEAVY RAIN WILL CREATE MAINLY LOCALIZED AREAS OF FLASH
FLOODING, WITH URBAN AREAS, ROADS, SMALL STREAMS, AND LOW-LYING
AREAS THE MOST VULNERABLE.
A WAVE OF LOW PRESSURE WILL MOVE ALONG THE FRONT OVER THE
ATLANTIC, STREAMING MOISTURE WESTWARD INTO PARTS OF THE EASTERN
SEABOARD, PRODUCING LIGHT RAIN ALONG THE COAST AS FAR NORTH AS NEW
ENGLAND BY WEDNESDAY NIGHT. IN ADDITION, THE FLOW OF MOISTURE OFF
THE WESTERN GULF WILL TRIGGER SHOWERS AND THUNDERSTORMS OVER THE
SOUTHERN TIP OF TEXAS THROUGH FRIDAY.
AN UPPER-LEVEL LOW OVER NORTHERN CALIFORNIA WILL PRODUCE LIGHT
RAIN AND EMBEDDED THUNDERSTORMS OVER PARTS OF THE NORTHWEST,
NORTHERN CALIFORNIA, AND GREAT BASIN THROUGH THURSDAY EVENING.
ALSO ON THURSDAY, THE SHOWERS AND THUNDERSTORMS WILL MOVE INTO
PARTS OF THE NORTHERN HIGH PLAINS, NORTHERN/CENTRAL ROCKIES, AND
ON FRIDAY, OVER PARTS OF THE UPPER MISSISSIPPI VALLEY.
FURTHERMORE, SMOKE FROM WILDFIRES HAS PROMPTED AIR QUALITY ALERTS
OVER PARTS OF THE NORTHWEST.
