Thursday AM Forecast: Moving from a stormy pattern to a sweaty one this weekend
Passing showers and thunderstorms continue to end the workweek. This weekend brings drier conditions and much warmer temperatures.
Today & Tonight: Early morning showers and thunderstorms in the Capital Area may make for a messy Thursday morning commute. The rain will continue through the morning hours before tapering off around lunchtime. A few spotty showers may be able to pop off this afternoon, although most of the energy needed for storm development will have been used up during this morning's round of storms. Thursday afternoon will be mostly cloudy and muggy with temperatures in the upper-70s to mid-80s. Overnight, temperatures will fall to the upper-60s, with a few areas of patchy fog that may impact your Friday morning conditions.
Friday: Overall, Friday will be warm and muggy under a mix of sun and clouds with afternoon highs nearing 86° in the Capital City. While broad coverage of afternoon storms is not expected, isolated showers and storms may develop and impact outdoor plans going into Friday evening. Those with Friday plans, like heading to cheer on the Tigers at Alex Box Stadium, should closely monitor the forecast.
This Weekend: Storm chances are finally put to a halt over the weekend as an upper-level ridge builds over the southeastern U.S.. With drier conditions and increasing sunshine, temperatures will begin to climb. Highs will reach the upper 80s on Saturday and closer to 90 degrees on Sunday. The humidity will add a summertime "sticky" feel to the air.
Up Next: The final days of April will stay very warm and muggy. High temperatures near 90 degrees are also forecast for next Monday and Tuesday. Be sure to stay hydrated as your body adjusts to the warmer, steamier conditions.
