The coldest air of the season swept down the Florida peninsula Sunday morning, knocking temperatures into the low 60s in coastal areas of South Florida, the 40s around Tampa and the 30s in North Florida.
It was 43 in Gainesville and the mid-30s east of Jacksonville, where a freeze watch was posted for Monday morning.
The cold snap in South Florida will be short-lived, since winds are expected to swing around to the northeast and east by Monday night bringing in warm air off the Atlantic.
By Wednesday, temperatures should be back up to near normal, which is a high of around 80 with lows in the upper 60s to near 70.
Moisture may work its way back into the area on Thanksgiving Day, but partly sunny skies are in the forecast with a good chance of mashed potatoes and gravy.
While the Florida peninsula rejoices (or scowls) at the cool pre-holiday weather, Invest 90L in the Caribbean finally appears poised to do some tropical business in the Carribean. National Hurricane Center forecasters upped the chance of development into a depression or storm to 50 percent by Tuesday, and the system was producing vigorous convection south of Jamaica.
But with cold air, high pressure and a projected march of fronts taking control over Florida, the Bahamas and even western Cuba, it looks like the system will remain locked up for most of the week, meandering east of Central America.
Most forecast models have 90L drifting into Central America eventually, and only a couple of outliers have it moving toward Cuba.
It looks like this will be one for the statistical record, although it’s not uncommon for a storm to be identified by the NHC in post-season analysis.
And last January’s Hurricane Alex was a reminder that out-of-season storms are not impossible and as quirky as the weather can be, continue to expect the unexpected.
