It’s tempting to conclude that the cool weather season is over in South Florida, that the A/C is set, the windows are closed, and the light jackets are returned to the back of the closet.
Not so fast, though, National Weather Service forecasters say.
An exceptionally strong cold front appears poised to roll through the Florida peninsula at the end of the week, delivering a shot of January-type air that should produce another round of open-window-weather as we close in on the Passover/ Easter holidays.
The week looks pre-summer sultry, with highs in the mid-80s even on the Atlantic coast and lows dipping only to the mid-70s at night. Balmy winds will blow out of the southeast, and with the April sun high in the sky you’ll be cranking up the car’s A/C to high every time you jump behind the wheel.
But the cold front that slides through Thursday night looks for real (at least for now), driving temperatures down into the low 60s by Saturday with highs only in the mid-70s. It’s worth noting that 75 is the average high around South Florida in January.
Before the front arrives: “South Florida will be under prevailing south-southwesterly flow though the period, with only minimal east coast sea-breeze development,” NWS forecasters said in their Sunday analysis. “The result will be very warm temperatures, potentially approaching record highs, in the mid-upper 80s and low 90s.”
Forecasters are calling for seasonable temperatures next weekend, and much drier air should make for some very pleasant conditions.
If the forecast pans out, though, and highs only reach 75 with lows around 60, that would be around 5 degrees cooler than normal highs and lows of 80 and 64. (In fact, the normal high ticks up to 82 in Miami on Wednesday.)
Of course, strong cold fronts in April aren’t all that unusual, although record cool maximum temperatures creep into the mid-70s by the middle of the month.
Record lows in West Palm Beach are in the 50s all the way through the end of May, but it’s interesting to note that from April 1 to May 31, only three record lows have been recorded in this century — the April 16 low of 50 set in 2007, the April 24 low of 53 set in 2012, and the April April 25 low of 50 set in 2005.
None of the record lows in May were set in this century, although the May 1 record of 54 was set in 1999.
On the other hand, 23 low temperature records in May were set before 1930 in West Palm Beach; and 19 record lows in April occurred prior to 1930.
