Clouds and overcast this morning are the result of low pressure moving through the upper Great Lakes region. This weather system will push a cold front through eastern Ohio during the morning that could bring a brief period of drizzle or light rain to the Valley in some areas. The odds for precipitation will diminish by lunch time as the boundary shifts off to the east.
High pressure will bring dryer air into the area for the afternoon allowing skies to gradually clear in the afternoon. Sunshine should make an appearance but temperatures today will remain cooler than normal. Highs this afternoon should reach the upper-50s.
Skies will become clear overnight allowing for colder temperatures tonight. It looks like a lot of locations could get to near freezing one last time. The dry air should keep the threat for frost at bay but some locations could see freezing. I’m covering my young plants up as a precaution just in case.
Generally speaking high pressure will keep dry weather an mild temperatures going through Monday. A warm front lifts through the region on Tuesday that will push temperatures well above average. Tuesday’s highs could soar to around 80°. Dry and mainly sunny conditions look to dominate our weather pattern through the early week period.
A series of low pressure systems and upper-level troughing will bring back periodic chances for rain and thunder as we enter the mid-week period. Instability aloft looks to be a little stronger on Wednesday which would bring a better chance for thunderstorms in the afternoon and evening. At the very least, there appears to be a fair amount of moisture present. Should this indeed turn out to be the case we can expect a mainly wet period for the Valley through Thursday.
High pressure moving east through the region should keep dry weather going Thursday night and Friday. Cooler air will return to knock temperatures back to the 60s as we head into the weekend. As the high shifts off to the east and a southerly flow set up we should see daytime highs inch back up to around average on Saturday.
Have a great Sunday and be safe out there.
