High pressure will keep the Valley dry with relatively warm temperatures this afternoon. Highs in most locations will reach the upper-50s today. That’s 10° to 12° above normal for us.
Clouds will increase this afternoon as a low pressure system advances into the Ohio Valley tonight. This will result in increasing odds for rain showers spreading east into the Valley on Saturday.
The good news with this system is that temperatures will remain warm and all of tomorrow’s precipitation will fall as rain.
By Sunday the low will be positioned north of the Valley. It will also trail a cold front that should sweep through east-central Ohio late Saturday night into early Sunday morning. Drier air behind the front will bring a quick end to rain chances Sunday.
The warmest part of Sunday will occur in the early Morning. Temperatures will remain flat and in the low-40s as colder air flows in from the north. Skies will likely remain cloudy for much of the morning but those should break and allow for peaks of sun in the afternoon as the drier air takes hold.
Colder air will remain in place Monday and Tuesday. Afternoon highs locally won’t get much better than the mid-30s for the afternoon high. Our weather should remain precipitation-free under building high pressure.
A LITTLE PRE-CHRISTMAS SNOW?
A strong storm system travelling up the Atlantic Coast will merge with another low pressure system moving into the Ohio Valley mid-week next week. While it certainly isn’t etched in stone, this could bring a chance for some light snow accumulation here in the Valley.
Much will depend on how far east the coastal system tracks. In these types of weather setups, the heavies snowfall usually occurs well off to our east. But, we may get enough of a glancing blow that potentially brings snow showers to our area. How much remains to be seen yet, but generally, these kinds of systems don’t result in big snow impacts locally. Anyway, it’s just something interesting to watch.
Temperatures will say colder next week after Saturday’s cold front.
Thanks for keeping it local. Have a great weekend and be safe out there.
