Heat doesn't really arrive until the Memorial Day weekend

Easterly breeze holds back heat wave today

By Mark Collins - Meteorologist

JACKSONVILLE, Fla. - Never a dull moment when it comes to our weather, but at least for now we will not be dealing with extreme heat. That comes this weekend which will be one of the hottest Memorial Day Weekends we have seen in a long time.

Here is more on the near record heat expected this weekend.
Meanwhile, in the tropics our first named tropical system has formed.

Locally, the next three days will be rather delightful, not too hot, yet warm. Humidity levels will remain rather low which increases fire danger, but an afternoon sea breeze will reduce some of the fire threat.

 

Increasing breezy conditions break the heat Thursday before a heat wave starts Friday.

Still not expecting any significant rain until the end of the month.

Today: High pressure strengthens offering slightly more easterly wind keeping temps in the low 90s today compared to yesterday's hotter mid 90s. Turning breezy, sunny. Highs in the upper 80s east of I-95 to 92° in western Duval. Southeast winds 5 to 10 mph increasing to east 15 to 20 mph in the afternoon.

Tonight: Clear in the evening then becoming partly cloudy leading to a cloudy start Thursday. Lows in the lower 70s. East winds 10 to 15 mph.

Thursday: Morning clouds then sunny and not as hot. Highs in the mid 80s. East winds 15 mph.

Friday: heat wave starts 95° and sunny.

Saturday and Sunday dry and mostly sunny with temps in the upper 90s and a heat index 100°-104°

Morning conditions will be pleasantly warm. Each morning will see inland sunrise temperatures around 65° with downtown to the beach temperatures starting off around 70°. Sunny skies will dominate area beaches, but as the afternoon heats up a bank of clouds will develop just inland of the intracoastal. 

This is the sea breeze front, and this is where we may see a few pop-up showers/thundershowers each day. Like what a few folks experienced on the Southside on Monday, these will be brief, almost "pulse-like". The chance of anyone getting an inland afternoon and or evening shower or thundershower is possible every day. The actual probability will be under 20% each day.

This weekend, starting Saturday is when afternoon temperatures head seriously higher.

Sunrise 6:29 a.m.
Sunset 8:17 p.m.

Inside baseball graphic, or in this case inside the weather office... The GFS forecast model is updated every 6 hours, these are the forecasted high temperatures for the next 10 days. Note the possible 100s on Saturday, Sunday and Monday.…
