We're not talking a run of upper 90's with Miami-like humidity but another one of those 90-93 stretches with dew points in the 60's. Humidity, hot, a bit hazy, with thunder threats around the region on at least a couple of the coming afternoons. Our hottest day may end up being Wednesday, which will coincide with our least thundery day of the week ahead. It's possible we nudge a bit higher than that 90-93 range on Wednesday, dependent on how much sunshine we get.
The end of the next round of heat approaches on Thursday as a trough of low pressure in the atmosphere moves into the Great Lakes, accompanied by a cold front and a chance of more widespread thunderstorm activity.
Given the atmosphere's working with a summery airmass and a fair amount of moisture, the threat of heavy rain and perhaps localized severe weather does exist with thunderstorms this week but keep in mind that the thunder threat will be scattered and isolated Monday through Wednesday. The best chances of severe, which may simply be a slight risk type of day, will likely coincide with Thursday afternoon and night with this approaching front.
