The first cold front of the season is on the way. How low will it go in Miami?
Florida is facing fall. Finally.
The first “cold front” of the season is expected to sweep through the state by Sunday, bringing drier air and lower humidity and some relief after a hot and wet September.
But we put cold front in quotation marks because unlike the 55-degree January nights earlier this year, this cooling off is just dropping temperatures in South Florida to 74.
Gainesville and Tallahassee gets the real cool upper-50s. Florida’s belly — the state’s central area of Tampa, Orlando, Melbourne, Fort Myers and Fort Pierce — should see 65 to 69 degrees.
Even with lows in the low- to mid-70s, South Florida can expect highs of 85 into the workweek, according to the National Weather Service in Miami.
Rain chance
Before the fall arrives, expect potentially flooding rains.
Miami-Dade and Broward counties are under a coastal flood advisory with a risk for moderate coastal flooding .
The weather service’s flood advisory runs through 8 p.m. Thursday; the simultaneous dangerous rip currents risk issued Wednesday expired that evening.
With rain chances peaking at 80% Thursday night and holding Friday, with the possibility of thunderstorms in the mix, South Florida may see flooding on roads.
“Do not drive around barricades or through water of unknown depth. Take the necessary actions to protect flood-prone property,” the weather service said in its advisory. Doesn’t sound like you’ll want to head to the beach at these times but if you do, be aware that the forecasted dangerous rip currents can sweep even the best swimmers away from shore into deeper water, the service said.
Rain chances drop Saturday and Sunday with a 40%-30% forecast, extending into a mostly sunny Monday, with a high of 85.
King tides
Peak king tides are also upon South Florida, adding to the mid-week weather water woes.
According to the South Florida Water Management District’s weekly tidal forecast, Wednesday was expected to be peak day with tides a foot or so above normal in Miami’s Virginia Key and Fort Lauderdale’s Port Everglades areas. Key West is forecast a bit lower, around a foot or just under.
Thursday’s high tides are:
- Miami: 11:22 a.m. and 11:28 p.m.
- Fort Lauderdale: 10:34 a.m. and 10:43 p.m.
- Key West: 10:50 a.m. and 10:57 p.m.
