...UNSEASONABLY COLD AIR TO AFFECT SOUTH FLORIDA MONDAY NIGHT THROUGH WEDNESDAY...

CONTINENTAL HIGH PRESSURE OVER THE CENTRAL UNITED STATES...AND A DEVELOPING VIGOROUS LOW PRESSURE AREA OVER THE WESTERN ATLANTIC EAST OF THE NORTHERN FLORIDA PENINSULA...WILL COMBINE TO PUMP UNSEASONABLY COLD AIR INTO SOUTH FLORIDA MONDAY NIGHT THROUGH WEDNESDAY. TEMPERATURES ARE EXPECTED TO BE THE COLDEST SINCE LAST FEBRUARY.

TEMPERATURES WHICH ARE ALREADY RUNNING BELOW NORMAL LATE THIS WEEKEND WILL TUMBLE TO AS MUCH AS 15 TO 20 DEGREES BELOW NORMAL TUESDAY AND WEDNESDAY. LOW TEMPERATURES BOTH TUESDAY AND WEDNESDAY MORNINGS WILL RANGE FROM THE UPPER 30S OVER THE INTERIOR SECTIONS SOUTH AND WEST OF LAKE OKEECHOBEE...TO THE MID AND UPPER 40S OVER THE METRO AREAS OF THE ATLANTIC AND GULF COASTS. NORTHWEST WINDS OF 10 TO 15 MPH AWAY FROM THE COASTS AND 15 TO 20 MPH NEAR THE COAST WILL PRODUCE WIND CHILLS RANGING FROM THE LOWER 30S WEST AND SOUTH OF THE LAKE TO THE LOWER 40S OVER THE METRO AREAS.

DESPITE A FAIR AMOUNT OF SUNSHINE... AFTERNOON HIGH TEMPERATURES TUESDAY AND WEDNESDAY WILL NOT FEEL MUCH WARMER...ONLY MAKING IT INTO THE 60S WITH STRONG AND GUSTY NORTHWEST WINDS OF 20 MPH MAKING IT FEEL EVEN COOLER. AFTER ANOTHER CHILLY NIGHT THANKSGIVING EVE...SOUTH FLORIDA WILL FINALLY SEE HIGH TEMPERATURES RISE BACK INTO THE 70S ON THANKSGIVING DAY.

PERSONS SHOULD PLAN ON DRESSING WARMLY THE NEXT FEW MORNINGS AS THESE ARE EXPECTED TO BE THE COLDEST TEMPERATURES TO AFFECT SOUTH FLORIDA SINCE LAST FEBRUARY. CARE SHOULD BE USED WHEN USING SPACE HEATERS...AND THEY SHOULD BE CHECKED TO MAKE SURE THEY ARE WORKING PROPERLY AND NOT CAUSE A ELECTRICAL SHORT WHICH CAN TRIGGER A FIRE. ALTHOUGH FREEZING TEMPERATURES ARE NOT EXPECTED... TEMPERATURES OF 40 DEGREES OR BELOW CAN DAMAGE SENSITIVE PLANTS...AND PROTECTIVE MEASURES MAY NEED TO BE TAKEN TO PROTECT THESE PLANTS.

Head south and its 57F at Boca Raton Exec (about 2 miles from the ocean).....the beaches will stay warm due to the warm gulf stream but once you get inland it will cool down fast.

It's been a *long* time since I have seen temps this cold for mid November. It's more like a typical January cold snap out there.

i cant wait until the ocean cools more.

yeah over on the west coast, you will also see temps stay in the upper 40s to around 50 right along the coast due to the low stratocumulous that is being generated from the relatively cooler air mass blowing over the warmer waters of the GOM. So Pinellas County (Southern and along the west side), Hillsborough county along the bay should see lows a good 5-10 degrees warmer than say 20-30 miles inland (e.g. Polk County).

It's very neat to see the dichotomy in temperatures between Tampa and St. Pete this time of year since the GOM is still so warm. Wouldn't be surprised to see something like this for lows:

Lows Tues nite:

Tampa: 42
St. Pete: 50

In fact you will see what I mean by using Gulfport in the nws.noaa.gov forecasts to see how much effect the GOM has on keeping lows higher along the coast.

Sorry, low temperatures last night were slightly warmer than initially progged in southeast Palm Beach and eastern Broward and Miami-Dade counties due to synoptics favoring less favored cold advection transfer to the surface.

ORIGINAL PROGGED LOWS FOR LAST NIGHT PER MIAMI NWS...

Boca Raton...

ORIGINAL FORECAST MONDAY LOW - 48 degrees
ACTUAL MONDAY LOW - 50 degrees

Pompano Beach...

ORIGINAL FORECAST MONDAY LOW - 49 to 50 degrees
ACTUAL MONDAY LOW - 51 degrees

Low overnight temperatures were also slightly warmer than initially forecast in the past few days at Fort Lauderdale, Hollywood, Deerfield Beach, and in other local areas.

Current data supports a significant backing off of cooler surface temperatures today in southeast Florida. In fact, current Miami NWS forecast indicates local highs reaching the lows 80s over the coming several days rather quickly. Initially a few days ago, temperature overnight lows were progged in the lower to middle 30s in the far interior and Lake Okeechobee regions and very low 40s along the coastal regions of southeast Florida for Monday and today; now, however, forecasts have significantly backed off on this, and synoptics don't support this cooler air to be sustained over the next few days in southern Florida. We should be back in the upper 70s in as little as the next two to three days.

Overall, this cold burst was much less impressive than some expected. Wind chill advisories, even inland, were canceled overnight for last night and tonight. No longer are any potential wind chill advisories needed, even overnight in interior southern Florida. The forecast lows for tonight, thus, have also backed off both for the interior and coastal regions of southern and southeast Florida. Expect temperatures overnight slightly warmer than what even may be progged now.
