Weather from NBC Storm Team 4 — Updated 10 p.m., Aug. 1, 2015

Overnight skies will become mainly clear with some patchy fog possible especially in the more rural areas. Tomorrow will be another spectacular August day with plenty of sun, low humidity levels, and highs again in the 90s.

The work week will bring an unwelcome change … higher humidity. As high pressure slides eastward and a cold front marches in from the Great Lakes, more muggy air will be drawn into our area. Expect a “feels like temperature” Monday near 100 when you factor in the increased humidity. As the front approaches Monday evening and night, we may see some scattered showers and storms, mainly in our northern suburbs, but most communities will remain dry. The cold front will stall to our south Tuesday but it will be close enough to keep the risk of an isolated shower or storm in the forecast. Otherwise, the weather will stay pretty hot and humid Tuesday. Highs Wednesday will be close to 90 so we could actually have a 13-day heat wave. Regardless, it will be warm and a bit humid with a small chance of a late day shower or storm. The best chance of rain for the upcoming work week looks to be Thursday. Stay with Storm Team 4 as we continue to track the humidity and timing of storms.
