High pressure shifting off to the east today sets up a warm breeze from the south that will bring a couple of dry and hot days to the Valley today and Monday. Temperatures locally will heat to the low-90s locally under a bright sun. Dew points this afternoon look to settle in the mid-60s so expect a touch of humidity today.
The warm breeze will keep temperatures warm overnight with lows dipping to the upper-60s by sunrise Monday.
Dry and hot weather continues into Monday. For folks who work outdoors, expect a much more humid day tomorrow with dew points in the low-70s and afternoon highs around 90°. Monday will be the hottest and most humid day of the workweek.
Odds for showers and storms will gradually increase Monday afternoon and evening. A cold front will advance ESE through the region Monday night into Tuesday. Showers and storms will be likely Monday night into Tuesday morning as the front moves through east-central Ohio.
The models have trended a slower arrival of the front with regards to general timing. This means that the front will likely not make it to our area until well after the peak heating of the day. This reduces the chances of severe storms with the front. Still, a strong thunderstorm can’t be completely ruled out so the Storm Prediction Center has highlighted the area for a Marginal Risk (Level 1 on a scale of 1 to 5).
While the threat for severe storms is low, there is a higher risk for heavy rainfall. The system has abundant moisture to tap into (as witnessed by the 70s dew points). Heavy downpours could lead to localized street flooding.
Showers will stick around through early Tuesday before moving east and out of the area by mid-morning. Drier and cooler air will filter in behind the front on Tuesday bringing temperatures closer to normal (low/mid 80s). Dew points will drop back to the low-60s making for much more comfortable but warm summer weather conditions.
WEDNESDAY THROUGH SATURDAY
We can expect mostly dry and uneventful weather through the remainder of the week. Relatively cooler air will maintain temperatures in the mid-80s for daytime highs and low-60s for nighttime lows. The lack of any significant weather features will keep chances for rain isolated at best.
We’re watching the potential for a more widespread rain event that could impact our area next weekend. A more organized low pressure system looks to travel out of the Mississippi Valley toward the Ohio Valley. This is pretty far out there yet and plenty of time remains to watch for precipitation trends with this one.
