Local view.
Rain Chances
Locally Friday will bring us a chance of thunderstorms at any part of the day with the passing of a warm front, some of these storms could be strong, some of the rain could also be heavy with some of the strong cells. It will be much warmer and more muggy, even on the warm side for some with partly cloudy skies Highs will be in the mid 80s Friday with lows in the 60s. Saturday there will be a chance of morning thunderstorms, then in the afternoon we will be left with hot and dry conditions, with Sunday having nothing but sunshine.
Long lasting Heat Wave Ahead
A very hot, muggy and potentially dangerous heat wave will plunge our area into very sweltering heat which will last for multiple days. Daytime highs on Saturday and Sunday be in the low mid 90s both days, with Upper 90 degree temperatures possible on our hottest day which will be Sunday, when we have sunny skies the entire day. Heat Index Values with temperatures this warm and dew points that high will be well into the 100 to 110.F range. What will make the heat even more of a problem, Low temperatures during the night will not provide any relief because lows will only fall to the mid to upper 70s, and wont be far below 80.F, which means heat index values may not fall below 85.F even at the dead of night. One thing that sets this heat wave aside from others in the past, is it will be the longest lasting heat wave in resent years. People in the local area should prepare for multiple days of sweltering daytime highs, and hot night time lows which will be considered dangerous for some to be outdoors during the hottest part of the day.
