Meteorologist Myles Henderson’s First Warning Forecast

Heating up before storms move in… We will start with plenty of sunshine this morning and temperatures near 70. Highs will climb to near 90 this afternoon, about 5 degrees warmer than yesterday. Clouds will start to build in this afternoon as a cold front approaches. A few isolated showers are possible this afternoon and evening but rain chances will climb overnight.

Expect mostly cloudy skies with scattered showers and storms Wednesday as the cold front moves through. Strong to severe storms are possible with gusty winds and heavy downpours. Highs will slip into the low 80s tomorrow afternoon.

Cooler air will move in behind the front for the end of the week. Highs will drop into the mid 70s by Thursday. A few showers will linger into early Thursday morning but we will return to sunshine by the afternoon. Expect plenty of sunshine and 70s on Friday.

Today: Mostly Sunny to Partly Cloudy, Isolated Showers (20%). Highs near 90. Winds: SW 10-15
