Sweating a bit more than usual for this time of year? Well, that’s because temperatures are a little above normal.
Low temperatures have been about 5 to 7 degrees above normal. And while the average overnight temperature in West Palm Beach for this time of year is 73 degrees, overnight lows the past few nights — and the forecast the next few nights — is around 79 degrees, according to Alex Gibbs, a meteorologist with the National Weather Service in Miami.
Daily high temperatures are around normal, Gibbs said. Historically, the average high temperature for this week is 89 degrees.
Also, the heat index reached 100 Tuesday afternoon in West Palm Beach. The index likely will remain between 98 and 101 for the remainder of the week.
West Palm Beach temperatures haven’t broken any records but that could happen Wednesday, Gibbs said. The record for the warmest low temperature on June 19 is 81 degrees, set in 1938.
Fort Lauderdale this morning tied the record for the warmest minimum temperature — 81 degrees — which was set in 1987.
Gibbs said the steamy temperatures are because of a high pressure ridge passing over South Florida. The hot sticky weather is expected to stay around for the next few days. A small tropical wave is expected to pass through this weekend, which will increase rain chances and possibly lower temperatures.
Wednesday brings a 30 percent chance of showers and thunderstorms after 1 p.m. in Palm Beach County and a 50 percent chance of showers and thunderstorms for the Treasure Coast. A high temperature of 88 degrees is expected. A low temperature near 76 degrees is expected for Wednesday night.
The low chance of showers and thunderstorms continues from Thursday through Sunday. High temperatures will range between 87 and 89 degrees and low temperatures will range between 74 and 76 degrees. Saturday brings the highest chances of rain, with 40 percent throughout the day.
Meanwhile, National Hurricane Center specialists are watching a tropical depression that is currently moving over northern Guatemala. The depression is not threatening Florida.
