COLD CONDITIONS TO CONTINUE THROUGH TONIGHT...

DISCUSSION...A COLD AND DRY AIRMASS CONTINUES TO ADVECT DOWN THE
PENINSULA THIS MORNING AS HIGH PRESSURE OVER THE LOWER MISSISSIPPI
VALLEY BUILDS EASTWARD. THE RIDGE WILL CONTINUE EAST TODAY AND
SETTLE OVER CENTRAL PORTIONS OF THE PENINSULA TONIGHT. AHEAD OF

HIGH TEMPS ONLY CLIMBING INTO THE MID TO UPPER 50S ALONG WITH
DEW POINTS DROPPING INTO THE TEENS TO MID 20S ACROSS THE MAINLAND.
TONIGHT WITH OPTIMAL RADIATIONAL COOLING AND A VERY DRY AIRMASS
TEMPS WILL DROP INTO THE 20S AND 30S ACROSS MOST OF S FL.
TERRESTRIAL HEAT AND THE PROXIMITY TO THE OCEANS WILL BE THE OCEANS
WILL BE THE ONLY SAVING GRACE OF THE COASTAL AREAS AND THE SE
COAST METRO, BUT FAR WESTERN SUBURBS OF THE EAST COAST COUNTIES
WILL STILL HAVE ISOLATED AREAS HITTING THE FREEZING MARK BY

THE INTERIOR MAY NOT FAIR AS WELL WITH TEMPS EVEN FALLING INTO THE
MID 20S FOR A FEW HOURS IN GLADES AND HENDRY COUNTIES. FROST WILL
ALSO BE A CONCERN IN THE EAST AND WEST COAST CITIES AS TEMPS FALL
INTO THE MID 30S... ITS JUST NOT EXPECTED ALONG THE IMMEDIATE
COAST. WARMING WILL BEGIN ACROSS S FL THURS WITH HIGH TEMPS
CLIMBING BACK INTO THE 60S DURING THE AFTERNOON AS THE DRY AIRMASS
ALLOW FOR A STEEP DIURNAL SWING AND THE RIDGE SLOWLY MODIFIES
THROUGH THE DAY... BUT EVEN WITH ANOTHER DAY OF MODIFICATION
ISOLATED AREAS OF WESTERN GLADES CO MAY ONCE AGAIN TAP 32 FRI

COASTAL SECTIONS OF S FL FRI MORN A LAND BREEZE IS EXPECTED AN
TEMPS WILL STILL LIKELY FALL INTO THE 40S OVER MOST COASTAL AREAS
WITH A FEW LOW 50S OVER EXTREME SE MIAMI-DADE. THE RIDGE WILL
FINALLY HAVE MODIFIED ENOUGH BY FRI NIGHT THAT NO MORE FREEZING
TEMPS AREA EXPECTED THROUGH THE REMAINDER OF THE PERIOD AND TEMPS
SLOWLY WARM AS THE RIDGE SLOWLY CREEPS INTO THE ATLANTIC. THE
SURFACE FLOW IS THEN EXPECTED TO BECOME EASTERLY LATE IN THE
WEEKEND AND DEEPEN ALLOWING FOR A FEW ISOLD SHRA TO MOVE IN FROM
THE ATLANTIC, BUT OTHER THAN THAT THE OVERALL PATTERN ACROSS THE
U.S. BECOMES MORE ZONAL THAN THE CURRENT PATTERN KEEPING THE
STRONG COLD FRONTS OUT OF S FL.

AVIATION...VFR CONDITIONS EXPECTED TO PREVAIL OVR ALL TERMINALS
THROUGH 22/06Z. SFC WINDS WILL REMAIN NW (320-340 DEGREES) AT 10
TO 13 KTS THROUGH AT LEAST 22/23Z WITH A BRIEF PERIOD OF GUSTINESS
OVR ERN TERMINALS DURING EARLY AFTERNOON HOURS. WIND SPEED SHOULD
SIGNIFICANTLY DECREASE AFTER 22/00Z TO 5 KTS OR LESS. /RHG

MARINE...THE RIDGE WILL CONTINUE TO BUILD IN THIS MORNING WITH

NIGHT. A LIGHT FLOW IS THEN EXPECTED THROUGH THE WEEKEND.

FIRE WEATHER...A VERY DRY AIRMASS CONTINUES TO SPILL INTO SOUTH

THE TEENS ACROSS PORTIONS OF THE INTERIOR AND IN THE 20S ALONG THE
COAST. EVEN WITH TEMPS ONLY RISING INTO THE MID TO UPPER 50S
ACROSS S FL SUCH LOW DEW POINTS WILL ALLOW RHS TO PLUMMET INTO THE

WILL BEGIN TO MODIFY DURING THURS, HOWEVER MOST OF THE MAINLAND
WILL AGAIN SEE RHS FALL BELOW 35% FOR MULTIPLE HRS. THE MOISTENING
