High pressure centered over New England will lose its grip on east-central Ohio today. We will still manage to get in another dry day with hazy sunshine. High clouds will thicken this afternoon as the next storm system approaches from the central Plains.
Today will likely be the warmest day of the week with afternoon temperatures reaching the mid-80s in most neighborhoods. After a pleasantly cool and comfortable morning, dew points will also gradually increase to the upper-60s making for a muggy afternoon.
TONIGHT THROUGH TUESDAY
A deepening low-pressure system will advance toward Ohio today. As the low inches closer tonight it will lift a warm front through the state.
As the front approaches from the south, odds for showers will increase and rain will be likely across east-central Ohio early Tuesday morning.
Tomorrow will be very muggy as warm moist southern air flows in behind the front. Clouds and rain will help keep temperatures in check, though.
Thunderstorms will begin to develop in the afternoon as we warm to the low 80s. Cloud cover and periodic showers will help limit instability here in the Valley, so the threat for severe thunderstorms in the afternoon is fairly low. Still, an isolated strong/severe thunderstorm can’t be ruled out completely at some point in the afternoon.
The Storm Predictions Center has the Valley highlighted in the marginal (low) risk category. Conditions will be better for severe thunderstorms just to our east.
The primary threats will come from damaging wind gusts but some hail is also possible. With such a juicy atmosphere in place, any thunderstorms tomorrow will have a lot of moisture to work with and heavy downpours will be possible.
Showers and storms will taper off and end Tuesday night as the center of low-pressure heads east toward Quebec. Our weather will gradually improve Wednesday as the system pulls east and high pressure begins to move into the region.
WEDNESDAY THROUGH FRIDAY
We’ll get a little taste of autumn Wednesday and Thursday. Temperatures will be much cooler behind the front on Wednesday and dew points will come down to the 50s as drier air takes over. High temperatures on Wednesday will only reach 70/71 degrees.
Sunshine along with cool and dry weather will be in full force Thursday with high pressure firmly in control. Temperatures will warm to the mid-70s for the afternoon high, but those 50s dewpoints will make it feel very pleasant.
FRIDAY THROUGH THE WEEKEND
Our string of fair weather days will continue through Friday. Temperatures will warm a bit under bright sunshine and a steady west-to-east air flow.
A warm front will lift through the region on Saturday. There is limited moisture associated with the front but we will need to bring in low odds for a few isolated showers as it lifts north through the region. Temperatures will warm back to around average behind the warm front on Sunday.
Just because we will have a brief period of cooler temperatures doesn’t mean summer is finished. Temperatures will warm to above average again next week.
