Record lows are expected across the region tonight as an Arctic blast from Canada continues to blow in, bringing below-freezing weather.
Temperatures could dip as low as 28 degrees in Tampa and near 30 degrees across much of Pinellas County as well, according to the National Weather Service in Ruskin.
Meteorologist Nick Petro said the last time it got that cold at Tampa International Airport was on Jan. 24, 2003. He said a new record could be set at Albert Whitted Airport in St. Petersburg, where the temperature on Jan. 3 last hit the freezing point in 1979.
When you factor in the wind, Petro said, temperatures could feel more like 15 or 20 degrees.
That has prompted the weather service to issue a wind-chill warning and to advise people to protect pets, plants and exposed pipes.
Petro said temperatures could be below freezing for several hours.
"It's going to be extremely cold," he said.
Cold enough to snow, even, if we weren't in the middle of a dry spell.That could happen, if we had some moisture," Petro said. "But the air is very, very dry."
Temperatures are expected to hover in the 40s for much of today before plunging tonight.
Clouds and wind near Tampa Bay and the Gulf of Mexico are expected to keep temperatures in most of coastal Pinellas and Hillsborough counties above freezing today, said Bay News 9 meteorologist Josh Linker.
The chilly forecast has strawberry growers scrambling to prepare.
"The biggest concern for tonight is the wind," said Gary Wishnatzki, owner of Wishnatzki Farms in Plant City.
Wishnatzki said workers at his 1,100 acres are picking as much as they can today, and also checking to make sure all the sprinklers are in working order.
Growers protect their berries by spraying them with overhead sprinklers throughout the night. The action of the water freezing on the berries generates heat which then protects the fruit, Wishnatzki explained.
But wind blows the water, meaning some berries won't get covered.
"If the wind doesn’t calm down, we’re in big trouble tonight," Wishnatzki said. "This is reminiscent of some of the bad freezes we had back in the '80s.''
Residents near Plant City and Dover are being advised to turn off well-water pumps tonight. Because farmers will be pumping more water, the aquifer could drop temporarily and cause pumps to burn out, county officials said. Pumps should remain off until the temperature rises Thursday morning.
It will be even colder in Hernando and Citrus counties, where temperatures could dip into the teens and prompt a "killing freeze" warning for the northern counties -- meaning temperatures below 28 degrees for more than three hours.
Gov. Charlie Crist issued an executive order this morning that temporarily allows trucks carrying produce to exceed usual height and weight restrictions. The intent is to give farmers as many options as possible for harvesting and processing crops before the freeze.
Billy Simmons, owner of Simmons Farms in Dover, spent New Year's Eve watching the University of South Florida Bulls play in the Sun Bowl in Texas. He planned to make a leisurely trip back home this week, but instead he and his wife left Tuesday and drove straight through -- 1,700 miles -- to get back and help prepare their 80 acres of strawberries for the potential freeze.
Simmons said the berries are particularly vulnerable because this is the first cold snap of the year.
"They haven’t acclimated to any cold weather," he said.
The cold, dry air in the midst of a drought also makes the area vulnerable to wildfires, prompting the National Weather Service to issue a warning through 5 p.m.
The cold snap will be short-lived. After a chilly Thursday, forecasters say temperatures will escalate into the 70s by the weekend.
