West Palm Beach is expected to reach a high of near 85 degrees today, and be even warmer tomorrow before a cool front approaches Friday.
Thursday’s high temperature could hit 86 degrees, according to the National Weather Service.
NWS forecasters said this morning the cold front is expected to be knocking on South Florida’s door midday Friday.
“There is also good agreement from the models on the magnitude of cooling behind the front,” forecasters wrote. “Temperatures Saturday morning could reach the upper 40’s in parts of Glades and west Hendry counties..
Coastal Palm Beach County is more likely to see lower 60’s with upper 50’s in the western areas of the county.
By Saturday, the high may only be near 70 and overnight lows could dip again to 60 degrees.
The normal high temperature for this time of year in West Palm Beach is 76 degrees, so we’ve been running nearly 10 degrees above normal.
Today’s record high in West Palm Beach is 86 degrees, so we could come close to breaking the record set in 1927.
Florida is on track for 2015 to be the hottest year on record. South Florida has been running about 3 degrees above normal, hence, the scorcher reference.
South Florida sweated through more unseasonably warm temperatures today with the high in West Palm Beach hitting 84 degrees at the Palm Beach International Airport.
But while that’s toasty, it’s no record-breaker. The record high temperature for Dec. 15 in West Palm Beach is 87 degrees set in 1951.
Miami’s Dec. 15 record is 86 degrees set in 2013. Today’s high was 2 degrees shy of breaking that record with the mercury reading 84 degrees.
Fort Lauderdale also hit a high of 84 degrees, shy of the 87-degree record set in 1977.
The remainder of the week is expected to maintain higher than normal temperatures until a cold front comes through Friday afternoon. That will knock the high Saturday to near 70 degrees with a low near 60 degrees.
For West Palm Beach, the normal high temperature this time of year is 76 degrees. That temperature was only reached twice so far this month during the daytime.
Colorado State University’s Department of Atmospheric Science stopped doing quantitative December hurricane forecasts for pending storm seasons in 2012.
But researchers are still issuing a more qualitative discussion of the factors that will influence the 2016 hurricane season, including the climatological chances that the U.S. and individual states will get hit by a tropical storm, hurricane or major hurricane.
This year’s discussion, released last week, relies on two main events for its hurricane predictions; whether El Nino will remain a strong influence through summer next year and the potency of the Atlantic Multi-Decadal Oscillation (AMO).
El Nino is known to knock down hurricanes by creating strong westerly wind shear, such as we saw during the 2015 hurricane season.
The AMO is a longer-term phenomenon that impacts sea-surface temperatures. Warm sea surface temperatures are like candy to growing hurricanes.
While CSU’s study, which was written by hurricane expert Philip Kotzbach with assistance from William Gray, looks generally at four scenarios affecting hurricane frequency and strength, it also gives climatological landfall probabilities for 2016. The probabilities are long term chances, taking into account data from the 20th century.
“While we are not issuing a quantitative forecast in this early outlook, we can still provide interested readers with the climatological probabilities of landfall for various portions of the United States coastline,” Klotzbach wrote.
For all of the U.S., Klotzbach said there is a 97 percent chance of a named storm making landfall. That could mean a tropical storm, hurricane or major hurricane.
Last week’s discussion also gives the climatological probabilities that a hurricane or major hurricane will impact specific states.
Klotzbach notes that none of the 27 major hurricanes that have formed since Wilma in 2005 made a U.S. landfall.
“The 10-year period that the U.S. has gone without any major landfalls exceeds the previous record of eight years set between 1861 and 1868,” he wrote.
“There is obviously a luck component that has played a significant role,” Klotzbach said.
He explains another part of why in a blog for the Capital Weather Gang written with Brian McNoldy. Basically an exploration of how an east coast low pressure system may be steering hurricanes away from the U.S.
Florida is singled out as being “remarkably lucky” to have not been impacted by a hurricane since Wilma. Klotzbach said there has been a marked decrease in hurricanes hitting the Florida peninsula over the past 50 years.
Bob Henson, a meteorologist and blogger for Weather Underground said CSU’s recent discussion makes him even more “eager to see how this very uncertain hurricane season will unfold.”
“As one would expect, the skill of these outlooks steadily improves as the hurricane season nears,” he wrote in a blog last week. “Even if it’s too soon right now to expect an accurate forecast for 2016, the latest thoughts from CSU make me even more eager to see how this very uncertain hurricane season will unfold.”
Surfing lazily on thermal air currents rising from the steamy earth, the graceful yet gruesome vulture is a sure sign that fall has arrived in the Sunshine State.
They are the original snowbirds – here before seasonal residents flocked to condos dug into South Florida’s shores.
And while the vultures typically arrive closer to Halloween than Christmas, one national wildlife researcher said the flight schedule of this year’s flock was a little delayed.
Read the full Palm Beach Post story on Florida’s vultures here.
“Some of our birds have just arrived in the last couple of weeks,” said Michael Avery, project leader for the National Wildlife Research Center at the U.S. Department of Agriculture in Gainesville. “We have some that we previously tagged in Key West that are still making their way down.”
Avery said it’s not clear yet what may have delayed the seasonal southern sojourn, but it’s possible record warm temperatures nationwide this autumn contributed to the rescheduling.
Temperature readings released this week by the National Centers for Environmental Information revealed that from September through November, temperatures nationwide were above average to record warm. Areas around the Great Lakes, where Avery said many of the birds he tracks spend their summers, experienced their hottest autumn in years.
Michigan’s average temperature was 51.6 degrees September through November, nearly 5 degrees above the 20th century average for that time period and the second warmest on records dating back 121 years. Minnesota’s average temperature of 49.5 degrees was 6.3 degrees higher than average.
Florida too is experiencing record warmth, with 2015 expected to go down as the hottest on record.
But maybe it’s not such a bad thing if the vultures’ visits are shortened, because once they get here, they can be quite a nuisance.
While a vital component in clearing carrion, black vultures also are predators, attacking and eating small animals, including newborn cattle, piglets and goats.
They also, for reasons unknown, have an affinity for rubbery materials and are known to pull windshield washer blades off cars, eat the rubber around windows, destroy outdoor furniture and pull the rubber splines from pool enclosures.
“They are a very important component of a healthy ecosystem, but vultures are one of those birds that do create a lot of hassles,” Avery said.
In a 2005 federal report on the management of damage by vultures in Florida, the scavenger bird topped the list of troublemaking fowl with 680 requests for assistance from wildlife services between 1993 and 2003. That’s more than six times higher than the second-ranked nuisance bird — the duck.
The report estimated that vultures caused $1.4 million in damage in the same period — everything from chewing up vehicles to leaving excessive fecal droppings.
The National Weather Service issued a special weather statement this morning warning of dense fog for all of Palm Beach County.
Visibility is less than a half mile in coastal and western Palm Beach County.
Drivers should use low beam headlights and slow down while driving through the fog early this morning.
The statement is in effect through 7 a.m. but fog could linger until shortly after sunrise.
Weather observations at Palm Beach International Airport reflect the fog started to form just before 5 a.m. as northwest winds stilled to 3 mph and the air temperature and dew point temperature met at 66 degrees.
The relative humidity shot to 100 percent and cloud heights plummeted from 3,000 feet to near ground level. Without strong winds or the sun’s dispersing rays, the low fog will linger.
The National Weather Service sends out a special weather statement, like the one this morning, when visibility is reduced to one-half mile. If visibility dips to one-fourth mile, a fog advisory is issued.
Dense fog is rare in Florida. Between 2000 and 2011, NOAA’s storm events database recorded just 35 days during which dense fog was present statewide. But those incidences can be lethal.
The database lists five deaths and 17 injuries directly attributable to dense fog, while Palm Beach Post archives list multiple car accidents in which fog was involved.
In March 2007, Boynton Beach resident Anita Zoet died after her car plowed into an 18-wheeler on Florida’s Turnpike in heavy fog. Four others were also killed in the accident that included a 12-vehicle pileup.
A year earlier, two people were killed and 20 injured in western Palm Beach County when smoke combined with fog to reduce visibility on State Road 80 and U.S. 27.
South Florida will see the sun again this week after cloudy to partly cloudy skies have blanketed the area since at least Dec. 1.
By Friday, rain chances are expected to be down to 10 percent, and skies are forecast to be mostly sunny, according to the National Weather Service.
Saturday’s forecast is “sunny.”
“It will be a nice change,” said David Ross, a meteorologist with the National Weather Service in Miami. “I’m sure it will be welcome.”
According to a weather station at the Palm Beach International Airport, every day this month has been either partly cloudy or cloudy. In technical terms, “partly cloudy” is a day when more than half of the sky is cloudless.
“Cloudy” is when 7/8 or more of the sky is covered by clouds.
The stubborn front stalled in the Florida Straits has been responsible for most of the clouds and rain.
Since Dec. 1, 5 inches of rain has fallen at Palm Beach International Airport. That’s 3 to 4 inches above normal for the first week of December.
A high pressure system is expected to push through later this week that will get rid of that soggy front to our south.
“By Saturday and Sunday, we’ll have the best couple of days we’ve had in several weekends,” said Arlena Moses, a NWS meteorologist in Miami. “If you look to Central and North Florida, they don’t have a cloud in the sky.”
