Storms to Keep Highs from Boiling Over
We start this last week of August on a hot, but relatively cozy note. Daytime highs for a third straight day have crested in the toasty mid and upper 80s on Monday, the word toasty signifying a low humidity brand of heat.
In fact, some would argue you can’t call the temperature hot until the mercury hits 90. Fair enough for those who stay in the AC all day, but hardly valid for landscapers and construction workers hard at it from 9 until 5 in the direct rays of the late summer sun.
Meanwhile much of America’s bread-basket (aka the Great Plains) are enduring a torrid late season heat wave. From the Twin Cities south the big D (Dallas) and from Denver east to Louisville, folks living in 20 states are braving 90-100 degree temperatures.
Last week I hooked onto the notion of that heat oozing its way eastward into our region. I forecasted a string of 90 degree days for this week based on the European model’s assertion that while the core of the heat would stay west of the Mississippi, pieces of heat would make it all the way in to our region.
That piece-meal arrival of the heat still seems on target, but with one big caveat; namely, the heat will be hard pressed to get established for more than 2 days at a time.
The reasoning behind this altered hot air theory focuses on the development of a train of thunderstorms in Northern Ohio at the nose of the arriving heat. In effect the heat will be transferring its energy not only to raising the temperature but also to generating violent thunderstorms.
The so called “thermodynamic” (thermo=heat, dynamic=energy) capacity of the arriving heat will go to work on Tuesday with afternoon-night action forming north of the Ohio State horseshoe then funneling southeastward through West Virginia. I-77 seems to be a first guess storm track with the Appalachian and Bob Evans highways also in play if cells form south of the “Shoe”.
A sudden southward turn in storms is being hinted at on Wednesday. If that occurs, the moniker “ANY PLACE, ANY TIME” for downpours with street flooding and power hits would be realized.
Here’s a look at how the heaviest rains may pool out the next 2 days.
So look for near 90 degree heat the rest of the week though the proximity and intensity of storms makes points west a better candidate for a late season heat wave than points east.
