A large area of high pressure will continue to be the dominant weather feature in east-central Ohio this week. Southerly flow on Sunday keep the stream of hot and humid air into the region causing daytime high temperatures this afternoon to reach the low 90s over most local neighborhoods. Despite the heat, dew points may stay just low enough to keep most of us from reaching heat advisory criteria today.
A weakening cold front may generate a few clouds today but any showers and storms from it should stay well south of the area. We will remain dry and warm tonight with temperatures dropping only to the low 70s.
MONDAY – TUESDAY
Although high pressure will remain firmly in control, a cold front will try to move in from the west on Monday. The main question is how far east showers and thunderstorms will be able to advance. The hi-res NAM (North American Model) likes the idea of a few scattered showers and storms moving through in the heat of the day tomorrow. For that reason, I’ve kept 50/50 odds for a spotty shower or storm Monday afternoon.
More cloudiness on Monday will keep afternoon temperatures in the upper 80s.
The weakening cold front washes out on Tuesday but I’ll still need to keep a low chance for a popup shower or storm over the Valley. Dew points on Tuesday will likely be the highest for the week and with temperatures reaching 91/93 degrees, heat indices around 100 to 105 are a good possibility.
Your mission on Wednesday will be finding a cool place to celebrate the July 4th holiday. Although dew points will be a tad lower, temperatures will soar to the low 90s under blazing sunshine. Wednesday evening will bring warm, although dry, conditions for fireworks.
THURSDAY THROUGH THE WEEKEND
Hot, dry and humid conditions will continue Through Thursday with most areas again getting to the low 90s for afternoon highs. But, a pattern change gets underway on Friday with a more substantial cold front. Shower and thunderstorm odds will increase on Friday as the front crosses the region.
The good news is Friday’s front will finally bring relief from the 90-degree temperatures for the weekend. Dew points will also become lower with drier air moving in. Temperatures Saturday and Sunday should drop back to the mid 80s – pretty much normal for early July.
