The dawdling low pressure system that has increased moisture and heat in South Florida the past several days continues to meander across the Tennessee Valley this morning, but a trailing cold front should reach Palm Beach County today.The front is forecast to hit South Florida just after midday, increasing the chances of rain to 70 percent with its arrival. The front should clear the Peninsula and move into the Florida Straits overnight. Check The Palm Beach Post live radar. This shows the forecast location of the front at 2 p.m. today. Thunderstorms are again possible with temperatures aloft remaining cool, while daytime heating is expected to reach upper 80s at the coast and possible 90s inland.The difference in temperatures between surface and higher in the atmosphere contributes to how robust the storm will be. Larger temperature differences mean stronger storms as heated air rises more quickly to clash with cooler temperatures aloft. National Weather Service forecasters in Miami said the biggest threats with today’s storms will be lightning and heavy rain. “Though strong wind gusts, hail and potential for waterspouts or landspouts can’t be ruled out,” forecasters said. Drier air should move in behind the front. WEATHER INSIDER: Like this… Read full this story
