JACKSONVILLE, Fla. – After a windy and cold day, the winds calm down this evening, but that means even colder temperatures tonight. Calm winds and clear skies make for the perfect combination for maximum overnight cooling. Most of our area is under the season’s first Freeze Warning- only excluding St Johns and Flagler counties and to the east of the St Johns River in Duval county. The areas under a Freeze Warning can expect temperatures to dip into the upper 20s, which could kill some plants. For tonight’s freeze, you must protect your plants, pets, and people- but it is not a hard freeze, where we should be concerned about pipes.
If we hit the upper 20s at the JAX airport, it will be the first time we have done so since January 19th, 2018- making it 1,048 days since we’ve gotten below 30°. The previous record for the longest time above 30° was 1,044 days from 1/16/1948-11/25/1950.
After a freezing start Wednesday morning expect to warm up into the upper 50s under mostly sunny skies. Winds will be lighter and we are not expected to see freezing temperatures Wednesday night.
Thursday marks the return of “Florida Winter.” We start off chilly in the 40s and warm up to around 70°. Expect partly sunny skies and winds out of the east between 5-10 mph.
Friday starts out a little cloudy with temperatures in the mid 50s. Expect to warm up into the mid 70s with building chances for showers and storms Friday evening into the overnight hours.
The weekend will be a little cooler, waking up in the mid 40s and warming up into the cool 60s. Saturday expect to hit 68°, Sunday will only warm into the low 60s under sunny skies both days.
