It’s warmer this week in Florida. But more changes are coming

This story was updated to include a bump in rain chances for South Florida and a flood advisory Wednesday in the Keys.

South Florida has had some nice weather lately: sunny with some slightly cooler temperatures.

But those days will be over once Wednesday rolls around.

Expect to see rain — and warmer temperatures than normal.

The Florida Keys is the first area to see some real rain of late.

On Wednesday morning, the National Weather Service in Key West issued a flood advisory after an inch fell in the Lower Keys from Mile Marker 0 to Mile Marker 10. Another inch or two was expected by noon.

Forecasters say highs are expected to be two to six degrees above average, with lows forecast to be nine degrees above average.

The good news is that even with the higher temperatures, it’s not expected to be overbearingly hot this week in South Florida. Highs will be around 80 and lows in the 70s.

The bad news is that any outdoor plans you made might get rained out.

The forecast was changed a bit on Wednesday. The rain chance in Miami-Dade and Broward counties is only 20% during the day but rises to 50% Wednesday night into Thursday morning, according to the National Weather Service in Miami.

Broward drivers should also be careful during Tuesday’s and Wednesday’s morning rush hour. Forecasters say patchy fog is possible, which could make it harder to see cars and children on the road.

What about the rest of the week? Here’s what the forecast shows:

Miami-Dade can expect to have a 20 to 40% chance of rain this week, according to the weather service. Other than Tuesday which has a low 20 percent chance of rain come nightfall, the best day for an outing seems to be Thursday night and Friday morning.

Despite having a 40% chance of rain late Friday into early Sunday, the weekend forecast doesn’t seem too horrible. Saturday night is expected to be rain-free, though you may want to wear a light sweater. Lows will be in the upper-60s.

Broward is forecast to have a 40 percent chance of rain until Thursday night, when rain chances are expected to drop into the low-20s. The low rain possibility should stay through Saturday.

While you might see some scattered showers Saturday, it doesn’t look like the rain is expected to ruin your Winterfest Boat Parade plans in Fort Lauderdale. The forecast says it’ll be partly cloudy, with a low around 65.

The Keys will also be seeing warmer than average temperatures with highs in the low to mid 80s, according to the weather service.

While forecasters say you can expect some rain all week, it’s a 10 to 20 percent chance of showers — which for South Florida standards means you can basically expect a beautiful day. Friday night might be the exception, when the rain chances increase to 30 percent, but they get low again by Saturday morning.

Hazardous Weather Outlook

If you enjoy your days out on the water, be careful the next few days.

Besides the patchy fog, there is a high risk for rip currents for the Palm Beaches on Tuesday and a moderate risk for the rest of the Atlantic Beaches, according to the weather service’s hazardous weather outlook.

An increase of swells will also create “hazardous marine conditions and elevated rip currents and surf” Thursday and Friday.
