Widespread rain likely on Thursday; Rain could be heavy at times

Posted Tuesday, October 27, 2020 8:47 AM

Another damp and dreary day for the Valley today. Some neighborhoods will get spotty light rain and/or drizzle this afternoon but these will become less likely as we make our way into the evening. Temperatures today will be cooler than our average high of 61° with most places seeing an afternoon high around 50°.

Socked in with clouds again today. Spotty light rain/drizzle will be possible just about everywhere in eastern Ohio this afternoon.

Drier weather is expected on Wednesday as weak high pressure build over the region. Tomorrow will also be a brighter day with a mixture of sun and clouds. Temperatures locally will warm a bit and we should see afternoon highs in the upper-50s at most locations.

HEAVY RAINFALL POSSIBLE THURSDAY
You might want to take some time to clear the gutters of leaves while it’s decent on Wednesday. Two strong weather systems will combine to bring periods of heavy rainfall to the Valley on Thursday.

NWS WEATHER MAP FOR THURSDAY 10/29/2020 Yes, that's snow along I-80 in northern PA and upstate NY.

The remnants of what now is Hurricane Zeta will travel into the Ohio Valley region Wednesday night into Thursday and merge with a strong storm system currently out to our west. With the addition of tropical moisture from Zeta, widespread rain is a pretty good bet for the bulk of the day Thursday. Some of the rainfall can be moderate to heavy at times.

The system will be a fast-mover, though. Rain locally is expected to taper off Friday morning. For the most part, rain locally should be east of us by Friday afternoon.

As of today, it looks like we will end up with an inch or two of rain. Some communities closer to I-70 might see a bit more than 2-inches if the current forecast remains on track.

NWSWPC Total Rain projection through Friday evening

TURNING COLDER ON FRIDAY
High pressure will eventually return dry weather to the Valley Friday afternoon but a surge of colder air will flow into east-central Ohio. Temperatures on Friday won’t do much better than the upper-40s. As skies continue to clear Friday night, temperatures across the Valley will dip to the upper-20s/low-30s for the first time in the season.

WEEKEND OUTLOOK
High pressure will bring dry and mostly sunny weather back to the Valley for the weekend. It will be on the chilly side with daytime highs in the low-50s and nighttime lows in the 30s.

Saturday is Halloween and it looks dry but chilly weather for trick-or-treat Saturday afternoon/evening.

LONG RANGE
Dry but cooler than average weather conditions are expected as we head into the first week of November. Warmer temperatures look to return by mid-week next week.

Thanks for reading the Valley’s most in-depth weather forecast. I’ll be working on the timing of Thursday’s rain in tomorrow’s update. Until then, have a good one!
