Severe Thunderstorm Warning 160, NWS Jacksonville, FL

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
215 PM EDT THU JUN 16 2011

.SHORT TERM (TODAY THROUGH TUESDAY)...
LARGE SURFACE RIDGE REACHES FROM THE LOWER MISSISSIPPI VALLEY AND INTO
THE CAROLINA COAST. AT THE MID LEVELS...HIGH PRESSURE EXTENDS ACROSS
THE AREA FROM THE NW AND NORTH WITH AN EMBEDDED WEAK TROUGH OVER THE
SE STATES. THE RIDGE WILL GRADUALLY SLIDE SOUTHWARD AND INTO THE
FLORIDA PENINSULA THROUGH THE SHORT TERM WHILE SLOWLY MIGRATING
WESTWARD. THIS WILL ALLOW FOR THE AFOREMENTIONED TROUGH TO DIG
FURTHER SOUTH AND BRING LOW CHANCES OF SHOWERS AND THUNDERSTORMS
ACROSS THE NORTHERN HALF OF THE FORECAST AREA ON MONDAY...THEN SLIGHTLY
POSSIBLE BETTER COVERAGE ON TUESDAY.

THIS AFTERNOON AND EVENING...EXPECT WARM AND DRY CONDITIONS UNDER
PERSISTENT HIGH PRESSURE ACROSS THE FL PENINSULA WITH POSSIBLE
ONSHORE/SEA BREEZE CIRCULATIONS RETURNING IN THE AFTERNOON HOURS.
THEN ON MONDAY THE TROUGH TO OUR NORTH WILL BRING LOW-END CHANCES
OF THUNDERSTORMS FROM TAMPA BAY AND NORTHWARD.

BY TUESDAY...INCREASING LOW LEVEL MOISTURE WILL COMBINE WITH
DAYTIME HEATING AND SEA BREEZES TO BRING ISOLATED THUNDERSTORMS
ACROSS THE FORECAST AREA.

AFTERNOON TEMPERATURES REMAIN WARM IN THE LOWER TO MID 90S...AND
LOWER TO MID 70S FOR MORNING LOWS.

&&

.LONG TERM...
LOOKS LIKE THE FORECAST AREA IS GOING TO BETWEEN AN AREA OF
INDUCED TROUGHING ALONG THE EASTERN SEABOARD AND A HIGH PRESSURE
CENTER OVER THE NORTHEASTERN GULF OF MEXICO. LOOKS LIKE WE WILL
SEE SOME ENHANCED DIURNAL CONVECTION EACH AFTERNOON AND EVENING
ALONG WITH ABOVE CLIMO TEMPERATURES FOR THE PERIOD. EXPECT THE
GREATEST TEMPERATURE DEVIATIONS TO BE OVER THE SUWANNEE VALLEY AND
INTERIOR SOUTHEAST GEORGIA.

&&

.AVIATION...
SMOKE IS GOING TO CONTINUE TO BE AN ISSUE ACROSS SOUTHEAST GEORGIA
AND ESPECIALLY KSSI OVERNIGHT. SOME SMOKE MAY DROP FROM UPPER
LEVELS INTO THE JACKSONVILLE METRO AREA DURING HE OVERNIGHT HOURS
BUT DO NOT EXPECT SIGNIFICANT VISIBILITY DROPS AT THIS TIME.

&&

.MARINE...
AS A RIDGE GRADUALLY ESTABLISHES ACROSS THE EASTERN GULF DURING THE
NEXT COUPLE OF DAYS...WINDS BECOME LIGHTER AND ALLOWING FOR SEA
BREEZES TO DEVELOP NEAR THE COAST EACH AFTERNOON. WITH THE RIDGE IN
PLACE...WINDS AND SEAS ARE EXPECTED TO REMAIN BELOW HIGHLIGHT
CRITERIA THROUGH THE FORECAST PERIOD.

&&

.FIRE WEATHER...
SUN AND MON MAY SEE CRITICAL RH INLAND BUT BRIEFLY AND WINDS ARE
EXPECTED TO BE SLIGHTLY LOWER.
