The NWS has started to put watches, warnings and advisories out in anticipation of the heat dome setting in. This will be a multi-day and possibly even a multi-week event. We already see the gray color in Cincinnati for an air quality alert tomorrow, which will probably get extended for a few more days.
It's been 6 years since we've hit 100° (June and July of 2012), but I think there's at least an outside chance we hit the century mark in the next 7-10 days.
Starting Friday, most models have us at 90° or above for the next six days:
A lot of people have been talking about how hot the GFS has been running the past few days, but regardless if we get that warm, I think the heat index easily hits 100° at least one of the next seven days.
This is just a primer for what we have to come. I'll be posting more in the coming days about what should be our first real heatwave in a while.
Wouldn't hitting 100 with such damp ground in this area would be pretty unusual? If we did, I'd guess we'd probably give the heat index record of Appleton, WI circa July 13, 1995 a run for its money.
