Highest totals in Central Florida were in Okeechobee County, where an observer measured 2.72 inches, while in Brevard County there was a report of 2.06 inches on the coast.

An observer in Okeechobee reported 1.86 inches; while 1.44 inches fell just west of the lake; 1.42 inches in Fort Myers; 0.16 of an inch in Tampa; 0.77 of an inch in Sarasota;

National Weather Service totals as of 12 p.m. included 0.47 of an inch in Melbourne; and in Orlando, 0.35 of an inch.

The National Weather Service in Miami said 1.05 inches fell in Naples; 0.61 of an inch fell in West Palm Beach; 0.36 of an inch fell in Miami; and 0.24 of an inch fell in Fort Lauderdale.

In the Keys, Marathon had about a quarter of an inch.

I’ll have a roundup of the state’s low temperatures on Sunday morning.  Some freezing temperatures may occur in North Florida, and frost may form inland from the Nature Coast northeast of Tampa.

South Florida should see mostly 40s with lows closer to 50 on the Southeast Coast, the National Weather Service says.

Parts of Broward County were slammed with more than 5 inches of rain Tuesday and early Wednesday as showers and storms from the Bahamas moved into the Florida peninsula.

Rainfall maxed out at 5.86 inches in east-central Broward, according to a 24-hour analysis by the Community Collaborative Rain, Hail & Snow Network.

Officially, the National Weather Service said Fort Lauderdale-Hollywood International Airport picked up 0.53 of an inch while Miami International reported .40 of an inch. No rainfall was recorded at Palm Beach International, and West Palm Beach is winding up November with a precipitation deficit of 1.79 inches. Naples has a deficit of 1.82 inches.

Miami and Fort Lauderdale, on the other hand, have built up significant surpluses this month.

Light amounts were observed elsewhere on Florida’s East Coast Tuesday, except that almost an inch fell in northeastern Martin County and 1.62 inches was observed in southeastern Indian River County.

The Treasure Coast has been running slight precipitation surpluses, but Orlando has a monthly rainfall deficit of 1.83 inches.

Key West record

CHILLING OUT IN KEY WEST: Tuesday marked the anniversary of the coldest November high ever recorded in Key West — 61 degrees. The record was originally set in 1885, and was tied in 1903 and again in 1914. Temperature records began in  Key West in 1872. (Credit: NWS-Key West)

RECORD WATCH: Tuesday’s low in West Palm Beach, 75, tied a record for warmest minimum temperature for the date, previously set in 1990.

POLAR VORTEX WATCH: Wednesday’s run of the GFS depicts a major sweep of cold air from Canada barreling its way into the Gulf Coast and the Florida peninsula the middle of next week. The Eastern U.S. and Florida remain in the grip of unusually cold air through at least Saturday, December 9, followed by another push of Arctic air late in the weekend.

The forecast model has overnight temperatures in the low 40s over coastal areas of South and Central Florida during this period with highs edging only into the low 60s.

Under this scenario, single digits would be headed for the Upper Midwest as far south as the western suburbs of Chicago, and the Northeast would see teens.

Since the forecast run is still seven-ten days out, expect changes with subsequent runs of the long-range models.

Key West beats 136-year-old rainfall record; North Florida swamped

It was a wet Thanksgiving from the Florida peninsula’s tip to top, with two cities setting rainfall records. Parts of North Florida picked up more than 5 inches of rain.

Key West set a daily record with 0.98 of an inch, beating the previous record of 0.78 set 136 years ago in 1881.

Gainesville’s official total was 2.53 inches, which broke the previous daily record for November 23 of 0.93 set in 1977.

Summerfield, Florida, southeast of Ocala, was smacked with a 48-hour total of 5.08 inches, according to the National Weather Service in Jacksonville. Palm Coast reported 4.07 inches over the same period.

South Florida, the Tampa area and Southwest Florida reported more moderate totals of between a quarter-inch and a half-inch. Ditto for East-Central Florida.

The end of November and the first week of December are shaping up to be pleasant and dry for the state, with above normal temperatures and below normal precipitation, according to NOAA’s Climate Prediction Center. The extreme southern tip of Florida may see close to normal rainfall over the period.

Key West temp

Here’s something we’ll be seeing a lot of this winter — Key West was the warmest spot in the nation Friday morning at 76 degrees. Highs over the weekend are forecast to be near 80 in the Keys; upper 70s to near 80 in South Florida; mid-70s in Central Florida; low 70s in North Florida and upper 60s in the panhandle.

Jacksonville shatters 140-year-old rainfall record; Florida braces for stormy Thanksgiving

Central Florida’s East Coast north to the Jacksonville area was hammered with up to 3 inches of rain Tuesday, and more wet weather was on the way from the Gulf of Mexico on Thursday and Friday.

Jacksonville busted a 140-year-old precipitation record Tuesday with 1.68 inches of rain, beating the old one-day record for November 21 of 1.16 inches set in 1877.

An observer in southeastern Baker County west of Jacksonville reported 3.42 inches to the Community Collaborative Rain, Hail & Snow Network. CoCoRaHS observers reported more than 2 inches as far south as Indian River County.

While South Florida was sunny and dry, a more widespread rain event was setting up for the holiday from an approaching system in the Gulf of Mexico.

Wednesday morning’s run of the GFS had the low moving into Florida from the Gulf around Tampa early Friday morning and then exiting into the Atlantic later in the day. The European had a little stronger low heading toward Florida’s Big Bend area late Thursday.

NOAA’s Weather Prediction Center put North Florida under a Marginal Risk for excessive rainfall on Thursday, an area north of Orlando from around the Big Bend area to Jacksonville on the Atlantic.

The National Weather Service in Jacksonville warned that up to 4 inches of rain was possible from the system, which could cause “flooding problems in urban areas and areas with poor drainage. Will need to monitor event evolution closely.”

NWS Melbourne: “Low pressure moving out of the Gulf and across Florida always gets our attention for severe weather potential.”

NWS Miami: “The convection associated with this system could produce gusty wind and heavy rainfall. While the best dynamics appear to be north of the region, the availability of wind shear Thursday into Friday will need to be monitored as any convection that can tap into it could potentially create a severe weather threat.”

HURRICANE MARIA REPORT RELEASED: Southeastern Puerto Rico was hammered by almost 40 inches of rain after Hurricane Maria made landfall on the island on September 20, the National Weather Service in San Juan says in a preliminary report on the storm.

Maria hit Puerto Rico as a major Category 4 hurricane with winds of 155 mph — just below Category 5. But the exact wind speeds that battered the island remain unknown.

“Most if not all of the stations failed during the hurricane,” the report said.

Wintry temps in Florida’s forecast next week following wet holiday

January-style temperatures — with highs in the low- to mid-70s, and lows in the mid- to upper 50s — are on the way next week for South Florida as November winds down, according to the National Weather Service.

By Monday, even the Treasure Coast may not see 70 degrees for a high, with lows settling close to 50. And interior areas of Central Florida — and up into North Central parts of the state — may see lows in the 40s.

Monday’s forecast high in Jacksonville is only 62.

The wintry temps — for Florida, at least — will follow a wet holiday week. The rain started early Tuesday morning in South Florida as the cold front that blew through on Sunday began climbing back up the peninsula. Fort Lauderdale-Hollywood International Airport reported 1.85 inches as of 7 a.m., and a half-inch to an inch were common in other areas of the southeast metro areas.

There were some spots of very heavy rain. An observer for the Community Collaborative Rain, Hail & Snow Network west of Fort Lauderdale Beach reported 3.84 inches through 7 a.m.

Light amounts were reported on Florida’s West Coast, but that was about to change as rain appeared to be moving in from the Gulf of Mexico.

On top of all of that, a low pressure system expected to form in the Northeast Gulf was forecast to slide across Central or North Florida late Thursday or Friday, providing another soaking for the state as the weekend approaches.

Marathon temps

NATIONWIDE HOT SPOT: Sunday’s cold front began working its way north early Tuesday morning, leaving the Florida Keys in warm, tropical air. As a result, Marathon was the warmest in the U.S. at 8 a.m., with a steamy temperature of 78, according to the National Weather Service in Key West.  Forecast highs in the Keys were in the low 80s.

Heavy rain possible on Thanksgiving for parts of Florida; cold front triggers wild temperature swings

Wild temperature swings hit the Florida peninsula early Monday with readings plunging up to 33 degrees in 12 hours on the East Coast — and then bouncing back 21 degrees three hours later.

That was the scenario in Melbourne, where it was 85 degrees Sunday at 5 p.m. A cold front began sliding down the peninsula in Sunday night and by 6 a.m., it was 52 with a northwest wind. But by 9 a.m., it was 74 in Melbourne as the winds swung around to the northeast off the warm waters of the Atlantic.

It was “a great example of how meso (small) scale features affect our local weather,” National Weather Service forecasters in Melbourne said on their Facebook page. “Cool air behind Sunday’s frontal passage dropped temperatures into the lower 50s this morning.

“As this occurred, a land breeze formed between the cool air and warmer oceanic air to its east. As winds became northeast this morning, the boundary pushed back on to land. causing temps to jump into the lower 70s, as seen in mesonet data from Brevard County.”

Temperatures took a nosedive into the low 40s in North Florida and lingered, with some low- to mid-30s west in the Florida panhandle at 7 a.m.. It was 42 at Jacksonville International Airport — 29 degrees lower than Sunday’s high of 71 and a 38-degree plunge from Saturday’s high of 80.

The temperature bottomed out at 34 in Callahan, Florida, northwest of Jacksonville and 33 in Bristol, Florida west of Tallahassee.

It was in the upper 50s to low 60s in Central Florida and the upper 60s to near 70 in South Florida, where the cold front continued to sag toward the southern tip of the peninsula.

It was still steamy in the Keys with an 8 a.m. temperature of 75 in Key West and 76 in Tavernier.

But the front was already putting on the brakes and was forecast to begin edging back to the north on Monday night and Tuesday, settling into Central Florida. That will put South Florida and the Keys firmly back into the warm air, according to the National Weather Service in Miami and Key West, with highs around 80 Tuesday and Wednesday.

A non-tropical low is still expected to form in the Gulf of Mexico by mid-week, which should make for a wet Thanksgiving Day, according to forecasters. The low should barrel over the peninsula and into the Atlantic by the end of the week, finally bringing in slightly cooler and drier air.

Rainfall on Thanksgiving could be heavy in Central and North Florida, forecasters said. A lot depends on how far north or south the low pressure system goes through.

Forecasters recall historic November Key West deluge; timing of cold front debated

Record Keys rainfall

HISTORIC KEYS WASH-OUT: It doesn’t take a tropical storm to produce heavy rain in Florida. Sixty-three years ago, Key West was hammered with its second-heaviest rainfall on record — 17.05 inches on November 13, 1954. The rain continued into November 14 and the soggy storm total was 18.08 inches.  (Credit: NWS-Key West)

Parts of Florida’s East Coast were soaked for a fourth consecutive day Monday as summer-like moisture lingered and triggered afternoon downpours.

Observers in western Boynton Beach, in Palm Beach County, reported 1.61 inches Monday, although official National Weather Service sites had more modest totals of around a quarter of an inch.

A Community Collaborative Rain, Hail & Snow Network (CoCoRaHS) observer in Fort Pierce measured 1.34 inches while the National Weather Service in Melbourne said 0.66 of an inch fell at the Fort Pierce-St. Lucie County International Airport to the north of the city. An observer in southeastern Indian River County also reported more than an inch of rain.

Florida’s West Coast reported only a trace of precipitation, mostly in the Tampa area.

THANKSGIVING WEEK COLD FRONT UPDATE: The timing of arrival for the front — the strongest since the last three days of October — is uncertain, but it should pack a pretty good punch. NOAA’s GFS has it sweeping through South Florida on Sunday, the National Weather Service says, while the European model (ECMWF) brings it through later on Monday.

It looks like that will be followed by a warm-up on Thanksgiving, and then another significant cool-down at the end of Thanksgiving weekend.

Coolest lows during those periods, according to commercial forecasting services, should be in the mid-40s in the panhandle; the upper 40s in North Florida; the low-50s in Central Florida; and the upper 50s to near 60 in South Florida. Lows in the Keys may dip into the upper 60s.

RECORD WATCH: Melbourne set a new record warm low temperature Monday with 73 degrees. The previous record was 72 in 2008.

TROPICS WATCH: The window may be getting ready to close on possible subtropical development near the Azores in the North Atlantic. Disturbance 96L still has a 50 percent chance of becoming Subtropical Storm Sean over the next two to five days, according to the National Hurricane Center. But after that, upper level winds are expected to become unfavorable, forecasters said.
