Mild temperatures and gradual clearing today; Heat and humidity returns over the holiday weekend

Temperatures will briefly return to near normal today with precipitation chances keeping mainly to our south along a stalled frontal boundary. Above normal temperatures, higher humidity, and daily chances for isolated showers and storms will then return and persist through the first half of next week.

Much of the Valley received a nice dose of rain with last evening’s showers and thunderstorms. Reports from personal weather stations across the area indicate a general one-half to three-quarters of an inch fell across our area.

There is some patchy fog this morning in many spots. With not much air movement, it will take most of the morning to burn off and dissipate. Generally speaking, though, today will be a day of improving weather. Cloud cover is likely to linger through much of the morning but we should begin to see gradual clearing northwest to southeast as we go through the afternoon.

We’ll get a short break from the heat today. Temperatures will be about ten degrees cooler than the last several days, but, there will not be much of a break in the humidity. Dew points will drop back some but remain in the mid-60s – not nearly as dry as the models projected yesterday.

High pressure will make its way east to our north overnight and skies will clear out. Some fog develops again overnight as temperatures cool off to the low 60s and approach the dewpoint temperature.

The cooler temperatures today will be short-lived. High pressure will shift east to New England on Friday bringing back a southerly flow and above-average temperatures for the last day of August. Expect a mostly sunny day tomorrow with afternoon temperatures in the mid-80s.

We’ve been hinting at this since last weekend and it’s beginning to look even more certain that hot and humid conditions will stick with us through the first week of September. It all begins this weekend with a warm front lifting through east-central Ohio on Saturday.

And, just like that, we’re back up to the upper 80s.

Hot temperatures and muggy air will remain a factor all through the holiday weekend. Temperatures will hover in the upper 80s Saturday and Sunday – low 90s on Labor Day. Combine the hot temperatures with dew points returning to the 70s through the weekend and we’re right back into a soupy and very uncomfortable airmass.

The vast majority of the long weekend will be dry. But, with all this warm and humid air, it won’t take much of a trigger to fire off a random shower or thunderstorm during the heat of each afternoon and evening.

Hot and humid conditions will continue as we head back to work and school after the holiday weekend. Expect high temperatures Tuesday and Wednesday to remain in the low 90s with heat index values in the mid to upper 90s.

A pattern change does look to arrive for the second week of the new month. Ensemble forecasts show those hot temperatures giving way to more seasonal values for next weekend.

  1. Thanks for keeping us informed. The hot, humid days are not what I want, but at least I know to not plan on being outdoors for extended periods of time.
