The Boston Globe says: “There’s been no winter this winter.”

The city has had less than half its normal amount of snow so far this meteorological winter (December through February) and temperatures have been as warm as the 60s, even in January. Today’s forecast for Boston: sunny with a high of 63.

Temperatures have also been radically above-normal this winter across Florida.

But for much of the eastern U.S., including Florida, it looks like winter weather may be jammed in to the first week or so of March which, ironically, is the start of meteorological spring.

In our neck of the woods, temperatures are poised to fall off a cliff Wednesday night as a potent cold front rolls through, keeping winds out of the north for the weekend. Highs will be stuck in the 60s, even in South Florida, with lows in the 40s — low 40s in Central Florida; near freezing in parts of North Florida.

Temperatures around the state don’t really rebound until Tuesday, and after that temps return to more seasonal levels, which means around 80 in South Florida and upper 70s in Central Florida.

Some heavy snow is set to close out February in the Upper Midwest and Great Lakes States. Even so, the winter of 2019-20 will probably go into the books as one of the top five warmest on record, according to meteorologists.

SUNDAY UPDATE: Another round of heavy rain showers hit Palm Beach County’s coast Saturday night, leading to the cancellation of the Houston Astros/ Washington Nationals first spring training game in West Palm Beach, a game that was billed as a World Series rematch for the teams.

The teams were scheduled to meet Sunday afternoon. Rain chances were forecast to diminish throughout the day. Saturday night’s game was canceled after two innings.

Although the rain wasn’t as heavy as Friday night’s round of showers, a CoCoRaHS observer in Boynton Beach, south of West Palm, reported 0.93 of an inch in his backyard bucket. Parts of West Palm Beach received more than half an inch.

Coastal Broward County picked up around a quarter of an inch, and a few hundredths of an inch fell on the Treasure Coast. There were also some light showers in the Upper Keys.

Temperatures rebound into the 80s through Wednesday, after which a potent cold front is forecast to drive overnight temperatures down into the 40s, even in parts of coastal South Florida, with highs only in the 60s through the early part of next weekend. That’s around 10-plus degrees below normal for this time of the year.

ORIGINAL POST: Go figure. Meteorological winter ends next Saturday, and December 1 – February 29 is almost certain to go into the books with well above normal temperatures for the season. But just as spring gets ready to launch, a shot of Arctic air is poised to give Florida a January-type chill.

“Confidence is building that a chillier pattern may emerge behind the front late in the week,” National Weather Service forecasters in Miami said in their Saturday morning forecast discussion.

Friday morning lows/ Friday afternoon forecast highs: Miami, 53 and 67; Orlando, 42 and 60; Tampa, 44 and 62; Jacksonville, 37 and 60.

Forecast for Sunday, March 1: Miami barely makes 70; Orlando stays in the 60s on Sunday and doesn’t make 72 until Monday; ditto for Tampa, which makes 73 on Monday, the second day of March. (Weather Underground forecasts)

Ultra-long-term, AccuWeather is calling for below normal temperatures through most of March. And, as mentioned yesterday, NOAA’s Climate Prediction Center is forecasting above normal precipitation in Florida during March.

The new eight- to 14-day forecast issued by NOAA Friday calls for only two states to have below normal temperatures through the first week of March — Florida and Alaska.

The reaction of many Florida residents will be, well, enjoy the cool temps while you can because some serious heat can’t be too far away. But tourists and spring breakers who are beach-bound in March might be a little disappointed.

However, the pattern could change later in the month, as indicated by the CPC’s four-week forecast, which was also issued Friday. That contradicts the long-range AccuWeather forecast, calling for above normal temperatures in Florida from March 7-20.

RAINFALL REPORT: Most of the U.S. was dry Friday, the one exception being Florida’s East Coast and particularly, the southeast coast. The action was focused on coastal Palm Beach County, where 1.20 inches of rain was reported through 7 a.m. Saturday on Singer Island, according to CoCoRaHS.

An observer in the Boca Raton area reported 1.06 inches; and an observer in Deerfield Beach, Broward County, reported 1.16 inches.

Miami-Dade had just a few sprinkles, while observers on the Treasure Coast reported a few hundredths of an inch.

IT CAME FROM OUTER SPACE: A “small” space rock crashed into the atmosphere above the Dominican Republic during the early morning hours on Friday, Spaceweather.com reported.

“The fireball was so bright, many cameras recorded the flash,” science writer Tony Phillips said. A webcam in the U.S. Virgin Islands captured the event.

“An all-sky camera operated by the Sociedad de Astronomia del Caribe in Puerto Rico also saw it.”

Locals may be out looking for meteorites this weekend.

NOAA beefs up its computer capacity with major upgrade

Computer capacity

NOAA is poised to triple its computing capacity over the next two years, the agency announced Thursday.

In a news release, NOAA said it added “two new Cray computers” the so-called supercomputers from Hewlett Packard, each with a capacity of 12 petaflops, which will become operational in 2022.

“Coupled with NOAA’s research and development supercomputers in West Virginia, Tennessee, Mississippi, and Colorado, which have a combined capacity of 16 petaflops, the supercomputing capacity supporting NOAA’s new operational prediction and research will be 40 petaflops,” the agency said.

“This increase in high-performance computing will triple the capacity and double the storage and interconnect speed, allowing NOAA to unlock possibilities for better forecast model guidance through higher-resolution and more comprehensive Earth-system models, using larger ensembles, advanced physics, and improved data assimilation.”

I know what you’re thinking: What’s a petaflop?

I googled it and found this definition: “A unit of computing speed equal to one thousand million million floating-point operations per second.”

Does that clear it up? No, it doesn’t for me, either. But it sounds like these are some heavy-duty, ultra-high-tech, sci-fi-quality mega-machines, so get ready for some pinpoint forecasts.

March precip

THE UPDATED MARCH FORECAST IS OUT: The forecast, released by NOAA’s Climate Prediction Center Thursday, calls for equal chances of above- or below-normal temperatures in Central and South Florida in March, but below normal temps in the panhandle and North Florida.

Above normal rainfall is predicted throughout all of Florida, including the panhandle.

Taking a closer look, Thursday runs of the GFS suggest that a strong cold front will knock temperatures back to end the month, with lows in the 40s and highs in the 60s next weekend across the peninsula. Ditto for the first weekend of March, as lows sink into the single digits in the Upper Midwest.

In fact, long-range models show a cool first half of March across the country, from California to New England.

In any case, normal highs and lows around Florida start ticking up impressively in March. On March 1, normal highs and lows in Miami are 79 and 71; and 82 and 74 on March 31. Orlando: 76 and 54 to 80 and 58; and Tampa, 74 and 56 to 78 and 60.

*

COOL WEEKEND: Forecast highs and lows on Saturday include 71 and 66 in Miami; 67 and 53 in Orlando; and 70 and 51 in Tampa. Winds could gust as high as 30 mph in some areas, the National Weather Service said, so it looks like a rather blustery weekend.

A warm-up begins on Monday.

*

RECORD WATCH: Orlando tied a record high Wednesday with 88, matching the mark set in 1962. It was 87 in Marathon, which also tied a record high for February 19 set just last year.

Record warm lows were set or tied in Orlando (67); Miami (75, beating the old record of 74 set in 1929); Fort Lauderdale (75); West Palm Beach (75); Naples (73); Key West (78); Daytona Beach (67); Sanford (68); and Leesburg (69).

Tuesday was the first official 90-degree day of the year in Florida as Naples checked in with a high of 90 — the earliest 90-degree day on record for the city. Previously, the earliest 90-degree day in Naples occurred on February 19 of last year.

It was the first time Naples hit that summery mark since November 7. The last time Miami hit or topped 90 was on November 1.

The normal high in Naples for this time of the year is 78. The normal high doesn’t hit 90 in Naples until June 6.

There have been several unofficial 90-degree days, mostly in the inland areas of Collier County. And Orlando came close on February 13 — but no cigar — with a high of 89.

Tuesday’s 90-degree high in Naples smashed the previous record high for the date of 86, set just two years ago in 2018.

Other record temps around the state:

RECORD HIGHS (TIED): Orlando, (87); Tampa (84); St. Petersburg (83); Lakeland (86) and Leesburg (86).

RECORD WARM LOWS (SET OR TIED): Orlando (65); Sarasota (66); Leesburg (67); Miami (74); Fort Lauderdale (75); West Palm Beach (74); and Key West (78). In the case of Key West, the 78-degree low beat the old record of 77 set just one year ago.

Key West ties 93-year-old high temperature record

Meteorological spring begins a week from Sunday, but spring-like temperatures are already in place across the Florida peninsula, with some 90-plus readings in inland parts of South Florida.

In Broward County, Weston hit 90 and an observer near the Fort Lauderdale Executive Airport reported a high of 92.

In the Keys, Key West tied a 93-year-old high temperature record Monday with 84. And in Central Florida, Leesburg tied a record warm minimum temperature with 65.

Toasty temps are set to continue until Friday, when a cold front knocks temperatures back into the 60s and 70s for the weekend. until then, expect more record warm temperatures.

“Naples will have to be watched as the records there are mid to upper 80s and we will certainly be in that ballpark,” the National Weather Service said in its Tuesday discussion from Miami.

FINANCIAL STORM WARNING: There are plenty of pins that have the potential to pop the economic bubble that has been pumped up by artificially low interest rates set by world banks over the last 10 years. One of them is the spread of the coronavirus, which is already doing damage to the Asian economies.

Here’s another one: extreme weather.

A paper published Monday by experts at the University of California at Davis argues that there’s too much unpriced risk in the energy market due to weather-related events, especially excessively high temperatures.

“Unpriced risk was the main cause of the Great Recession in 2007-2008,” said author Paul Griffin, an accounting professor at the UC Davis Graduate School of Management. “Right now, energy companies shoulder much of that risk. The market needs to better assess risk, and factor a risk of extreme weather into securities prices.”

Excessive heat has the ability to impact agriculture, interfere with delivery of energy and water, and disrupt transportation.

“Despite these obvious risks, investors and asset managers have been conspicuously slow to connect physical climate risk to company market valuations,” Griffin said in the paper published by the academic journal, Nature Energy. “Loss of property is what grabs all the headlines, but how are businesses coping? Threats to businesses could disrupt the entire economic system.”

He added: “While proprietary climate risk models my help some firms and organizations better understand future conditions attributable to climate change, extreme weather risk is still highly problematic from a risk estimation standpoint,” he concluded in the article.

“This is because with climate change, the patterns of the past are no guide to the future, whether it be one year, five years or 20 years out. Investors may also normalize extreme weather impacts over time, discounting their future importance.”

Climate change shocker: Third of all species could be extinct by 2070

Most people consider sea level rise the biggest problem related to climate change, and that is a critical issue, especially if you live in coastal areas and states like Florida. But here’s another dire consequence: a third of all plants and animal species could be extinct in the next 50 years.

Researchers at the University of Arizona looked at localized plant and animal extinctions in the past that have occurred in specific areas. They found that up to 50 percent of species suffered local extinctions if maximum temperatures increased by more than 0.5 degrees Celsius and 95 percent if they increased by more than 2.9 degrees.

As a result, the rate of extinction is highly dependent on how much warming occurs in the coming years, according to the researchers, Cristian Román-Palacios and John Wiens, of the Department of Ecology and Evolutionary Biology at the University of Arizona.

“In a way, it’s a ‘choose your own adventure,'” said Wiens. “If we stick to the Paris Agreement to combat climate change, we may lose fewer than two out of every 10 plant and animal species on Earth by 2070. But if humans cause larger temperature increases, we could lose more than a third or even half of all animal and plant species, based on our results.”

As one example, they considered the Alligator Juniper tree in Arizona. In flat lands, the plants are dying due to rising daytime temperatures. “Repeated surveys have shown that this species is literally being pushed up the mountain slopes under the impact of climate change,” the university said in a news release.

Here’s the kicker: Extinctions are projected to be two to four times more common in the tropics than in temperate regions. “This is a big problem, because the majority of plant and animal species occur in the tropics,” Román-Palacios said.

Both plant and animal species will be equally affected, the researchers said.

SPRING IN THE AIR: Clear skies with plenty of sunshine will give temperatures a boost through at least Thursday of this week, with highs rising into the low 80s on the East Coast and as high as the upper 80s in southwestern parts of the Florida peninsula, according to the National Weather Service.

Beyond that, NOAA’s Climate Prediction Center is calling for below normal temperatures in all of Florida from next Saturday into the following week.

NOAA will release its full March forecast on Thursday. The latest long-range CFS model shows cooler weather hanging on the first week of March followed by above normal temperatures as we head into the second half of the month.

RECORD WATCH: Vero Beach posted a record warm low Sunday of 71 degrees. It beat the old record of 70 set in 1965.
