An active and potentially stormy Sunday is on the way…although the weather will be quite variable with time and location. Lots of rain and embedded thunder is coming up from the southwest this morning…with some heavier downpours here and there. As we get into the afternoon we should get some drier air beginning to filter in from the west…resulting in a bit of sunshine and there an increasing threat of some stronger storms. SPC has a slight risk for severe today….mainly east of the Mississippi River from the Ohio River northeast into Indiana including much of So. Illinois east of I-57. If storms do develop….damaging winds but also isolated tornadoes are possible….especially in SE Illinois. Otherwise it will be warm, breezy and humid today…though by late afternoon skies should be gradually clearing west to east….and overnight some cooler and drier air will filter in from the northwest.
Monday looks like the weather pick day of the week with dry and pleasant conditions….and lower dew point/humidity levels. However the break looks short-lived as active weather looks to brush the area by Tuesday night into Wednesday….with more thunderstorms likely. Later in the week we’re back in an early-summer type pattern with a strong upper ridge developing over the southeastern U.S. We could see afternoon temps close to 90° by Thursday and Friday. A long ways off but the weekend looks to bring slightly cooler but potentially more active weather as the jet stream pushes back in from the north.
