Heat and humidity will be the big story on Wednesday prior to the possible PM thunderstorms and marginal severe risk ahead of a cold front. This will particularly be the case along and south of I-80, where peak heat index values of 100 to 105 degrees are forecast. Keep heat safety in mind if you plan to spend prolonged time outdoors on Wednesday.
Coverage of thunderstorms today could be somewhat low. However, any storms that develop will have the potential to become strong to severe with a threat for large hail (possibly to the size of golf balls) and damaging wind gusts (up to 60-70 mph). Conditions will rapidly improve from west-to-east through the mid-late evening hours as a cold front sweeps through the region.
