Today was our sixth straight day of 90°+ heat and the streak isn't over yet. What appeared to be our sixth straight day of a Heat Advisory quickly became our second Excessive Heat Warning of the season, and the warning has been extended through Saturday. Wilmington is forecasting temperatures in the very upper 90's in to the weekend and dewpoints close to 70°. That could make for an outright oppressive next few days.
While it's uncomfortable for those of us with AC, the unfortunate ones are those who still don't have power from the June 29th Derecho. As of a couple hours ago more than 61,000 customers in Central Ohio alone are still without power. While I don't mind opening windows and dealing with heat when it's a little warm, 98° with no breeze is unthinkable.
But we're not the only ones dealing with this historical heat wave. So far it looks like ten states have Excessive Heat Warnings, making the term "excessive" more appropriate than ever:
Relief is coming eventually, with a trough forecasted to move in late this weekend. In the meantime any cool off will have to come in the form of an afternoon storm. For a while it looked like we were in a pattern where we would see a pulse of energy ride over top of the ridge every other day, with storms last Friday and Sunday.
What does it mean for storms to ride over top the ridge? Right now we have a large blocking high pressure in the nation's midsection that is the cause of this massive heatwave. This ridge is strong enough that all storm systems are being pushed in to Canada and then back down on the eastern side of the high, as is seen today with what little active weather we have:
Tomorrow is just about the last chance for any of this rain to reach us before the trough moves through on Sunday, so in the meantime... keep those AC's on.
