We still had a weak frontal boundary cross east-central Ohio very early this morning. Unfortunately, this will not bring much of an impact on our temperatures going forward. The air behind the boundary is a little drier, though, and this will be reflected in the slightly lower dew points today. In other words, it will not be quite as humid today and Saturday as it was on Thursday.
Temperatures, however, will still be toasty warm. Most local neighborhoods will get to the upper 80s for the afternoon high today. Then, we’ll heat up to the low-90s on Saturday. We’ll have sun and clouds today but Saturday will be virtually cloud-free.
The humidity will return with a vengeance on Sunday, however. Dew points will soar to the low-70s and with air temperatures in the low-90s Sunday afternoon heat indices will likely end up in the upper-90s to near 100° locally. Sunday is going to be a very hot and humid day in the Valley.
A weak front will slip south across east-central Ohio Sunday night. There are questions regarding the timing of the front but a shower or storm could pop late in the day and Sunday night. If the front looks to arrive earlier in the day Sunday, we will need to watch for a potential for severe storms. At this time it does appear to move through too late, though.
Monday will remain hot and humid. An area of low pressure will move into the central Great Lakes region Tuesday bringing us increasing chances for thunderstorms. There are model timing issues with this system as well but the low will eventually push a cold front through the region during the second half of the week. This will keep daily odds for showers and storms going through mid week. Drier air will follow behind the front to bring lower dew points to the Valley late in the week.
