S. Florida heat streak ties overnight records

Palm Beach Daily News - - TODAY - By KIM­BERLY MILLER

A two-week streak of ab­nor­mally warm tem­per­a­tures is chal­leng­ing South Florida records and push­ing heat in­dexes to “con­cern­ing” lev­els into the week­end.

On Thurs­day, of­fi­cial weather ser­vice gauges in West Palm Beach cooled to only 82 de­grees, break­ing the 1991/1995 record of 81.

Of­fi­cial weather ser­vice gauges in West Palm Beach and Fort Laud­erdale cooled Wed­nes­day morn­ing to only 81 and 82 de­grees, re­spec­tively, ty­ing overnight heat records set in both cities in 1998.

Blame a stub­born Ber­muda high, which has had a hold on the state through much of the month, for the un­usual warmth. Fif­teen days have seen the mer­cury rise to 90 de­grees or warmer at Palm Beach In­ter­na­tional Air­port, in­clud­ing hit­ting a whop­ping 93 de­grees Sept. 19 and 20.

The nor­mal day­time high for late Sep­tem­ber is 87 or 88 with the nor­mal overnight low typ­i­cally drop­ping to 75.

Der­rick Weitlich, a me­te­o­rol­o­gist with the Na­tional Weather Ser­vice in Mel­bourne, said the ex­tra day­time heat has been aided by an east­erly sea breeze push­ing far­ther in­land and caus­ing show­ers and thun­der­storms to by­pass the coast.

“The storms in­crease cloud cover and rain­fall to re­ally cool things off, but we’ve been drier than nor­mal for most of the month and had higher tem­per­a­tures,” Weitlich said.

An av­er­age of 4.6 inches of rain has fallen over coastal Palm Beach County this month, which is more than 2 inches be­low nor­mal, ac­cord­ing to South Florida Wa­ter Man­age­ment Dis­trict records.

Mi­ami me­te­o­rol­o­gists warned Thurs­day of heat in­dex, or “feels like,” tem­per­a­tures in the triple dig­its into the week­end.

Through Mon­day, day­time highs in West Palm Beach are ex­pected to reach near 90 de­grees with overnights dip­ping into the up­per 70s.

This week­end, the Ber­muda high will move far­ther west with its cen­ter over the penin­sula. Its clock­wise flow is fore­cast to whip winds up to 15 mph, with stronger gusts. By Mon­day, east winds could in­crease to 16 mph with stronger gusts.

That means higher chances of rough seas and rip cur­rents through the week­end.

On Tues­day, a stronger high pres­sure sys­tem moves across the north­ern part of the United States, which could push a “back-door” cold front “pos­si­bly through South Florida,” Mi­ami me­te­o­rol­o­gists said.

Al­though un­cer­tainty in the fore­cast re­mains high, me­te­o­rol­o­gists said models have been hint­ing at the front with enough con­sis­tency they felt con­fi­dent putting it in the fore­cast.

Weitlich said a back-door front is one that comes from the north­east. He’s skep­ti­cal one would make it to South Florida this early in the sea­son.

“In terms of tem­per­a­tures, we cer­tainly won’t see much of a change,” he said.
