We’re in a period of some really pleasant mid-summer weather here in the Valley and I hope you are one of the many who are soaking up the sunshine, cooler temperatures, and the lack of humidity. I don’t see very much complaining about the weather all of a sudden.
Our moist humid airmass early in the week has been replaced by cooler and much drier air behind a Tuesday night cold front. This less humid air will stick around and make for some very pleasant – almost autumn-like -weather through Friday. What most folks notice the most, though, is the lack of any substantial moisture. That, of course, is reflected in our low dew points in the 50s.
High pressure centered over extreme NW Ohio will keep that northerly flow, and thus, cooler and drier air going yet today. That high will gradually shift east tonight and tomorrow to keep picturesque cumulus clouds and blue skies overhead.
Generally, temperatures this afternoon will warm to around 80° in most neighborhoods. Tonight will be another opportunity to sleep with the windows open. Skies will remain mostly clear overnight and we’ll cool off to the mid/upper-50s. As temperatures cool off to near the dew points tonight in low areas and along the river, there can be some spotty fog early in the morning again.
FRIDAY AND THE WEEKEND
Unfortunately, this break in the summer heat and humidity will be brief. While we probably won’t get back up to the 90s, our local temperatures will begin an uphill climb through the weekend.
Friday will be the most comfortable day of the mid-range with afternoon highs in the mid-80s. Dew points on Friday will still be pretty comfortable yet. Odds favor that we stay dry on Friday but a low-level disturbance off to the east will bring in just enough moisture to produce an isolated shower in the afternoon. I’ve included a slight chance for a passing shower Friday afternoon in our local forecast but anything any of us see will be light and brief. Chances are better that we end up with just an increase in the amount of cloud cover.
The weekend looks to be a good time to be outdoors doing yardwork of just enjoying some outside time. We get right back to mostly sunny skies again on Saturday but temperatures will continue to steadily warm. The humidity, though, will stay in check. Sunday will be the warmest day of the weekend but still, not all that humid for late summer.
Our weather pattern will become a bit more unsettled next week. Sunday night/Monday we’ll start to notice the humidity coming back with a warm front. For now, I’ve kept the threat for showers and storms out of the forecast but this might need to be changed in later updates. Rain or not, it will turn more humid again on Monday as dew points inch upward to the upper-60s once again. The arrival of an upper-level trough will set central Ohio up for a mainly west-to-east-flow which will bring almost daily opportunities for showers and storms through mid-week. Increasing moisture will keep warm and muggy conditions through early next week as well.
Much of next week looks to remain warm and humid with spotty showers and storms threatening just about anytime during the heat of the day.
