MIDWAY, Fla. (WTXL) -- The heat wave is close to ending. The change: a cold front that will slowly pass the region Sunday into Monday. The increased flow of moisture coming in from the Gulf of Mexico, coupled with the development of a low pressure system out west will contribute to widespread rainfall Sunday. A few thunderstorms will be possible as well.
Overnight lows into Sunday will be warm mainly because of high humidity and extensive cloud cover. Lows will struggle to fall below to upper 60s to lower 70s across the region. Into Sunday afternoon, daytime highs won't really be high at all. They'll likely only rise 2 to 4 degrees because the clouds will block most of the sunlight, plus, rainfall will keep the region feeling cool. Rain coverage will be at 70% for the entire region. Thunderstorms are definitely possible in the mix of rain and clouds.
Monday may feature some more cloudiness and showers but the majority of the rain should push away by then. Highs will likely range in the lower to mid 70s after starting off in the mid to upper 60s. We'll slowly warm up through midweek, but it wont be as extreme as the most recent heat wave. A modest cool down is expected by next weekend.
