Soaring summer temps on tap for weekend as high pressure builds

Weekend forecast

SATURDAY UPDATE: Summer will be off to a rip-roaring start in South Florida over the Memorial Day Weekend with heat index values around 100 degrees, according to the National Weather Service. Showers will be confined to the Everglades, they said.  It’s a hat-and-sun-screen weekend!

FRIDAY POST: There was a hint of coolness in the air around Florida Friday morning as the cold front that triggered showers and thunderstorms Wednesday and Thursday stalled out over the southern tip of the peninsula and began washing out.

At 7 a.m., the dew point in West Palm Beach had fallen to 66 degrees with an air temperature of 70. Dew points were in the low 60s around Lake Okeechobee.

It was in the low- to mid-60s this morning in Central Florida, including a reading of 59 degrees in Zephyrhills east of Tampa.

The coolest readings on the National Weather Service map were in Lake City and Cross City, in North Florida, where it was 57.

But this is Memorial Day weekend and the cool air will be short-lived. By the time you finish lunch, winds in South Florida will have swung around from the northwest to the northeast, and they’ll be out of the east by Friday night, drawing warmer and more humid air back to the coast.

High pressure builds in over the weekend, according to forecasters.

Highs over the holiday weekend will be near 90 — even in the metro areas — and in the mid-90s inland. Local weather forecasters will likely be talking about heat index values well in excess of 100 degrees, so it looks like summer will begin in earnest.

Rain is not in the forecast until toward the end of next week.
