Weather Watchers

Synopsis

We are finally seeing a few cells pop up near Jeffersonville and east of Zanesville in the heat of the day (97/Heat Index 103) with moderate instability (CAPE 2500, LI -8), but no real triggering mechanism and the frontal boundary across Lower MI. Upshot is that more pop-ups with quick downpours will develop but the coverage will be widely scattered at best, and then collapse by sunset.

Last evening I tracked the second of two strong convective complexes that formed west of Detroit and moved across northeast OH, but they developed farther north than the events Friday and Sunday, which began west of Chicago. End result is that we were spared issues for RW&B with storms thanks to a more northerly course. But it was the hottest (94) RW&B Day that I have logged since the early 1980s!

Last night we also enjoyed, as you undoubtedly noticed, the full (“Thunder”) moon. In August we get two full moons in a month—which happens once in a blue moon.

A possible kicker later tomorrow could increase storm coverage, though wind shear remains weak and the frontal boundary will be near Lake Erie as it sinks slowly south before dissipating early Friday. That means extended heat and humidity with isolated to widely scattered late-day storms through Saturday and highs in the mid-90s (heat indices at or above 100). Genuine relief arrives late Saturday night with a sagging cold front, some storms lingering into Sunday, and temperatures returning to the seasonable 80s. Much less humid conditions will prevail next week!
