A few flurries will be possible along and just behind the front into early Thursday.
Strong CAA (cold air advection) in the low levels will battle lots of sunshine Thursday afternoon. H9 temps progged to drop from near -9C Thursday morning to -15/-16C by midday. Than in itself should hold temps steady in the upper teens to near 20F or perhaps cause them to slowly fall .
Ridging aloft and at the sfc builds in Thursday night. Low layers will decouple as sfc high drifts overhead - idea for radiational cooling - temperatures will likely drop into the single digits by Friday morning.
Warm advection clouds will sweep over the region Friday night but with very dry low levels... no precip is expected.
Ready for some warmer news ???? On Sunday and early next week, much warmer air starts flooding into the region with H85 temps warming to near +10C by Monday evening!!
Temperatures will respond and push well into the 50s (with some locations nearing the 60s) early next week.
It won't last long though... a strong cold front will sweep the area during the Tuesday time frame bringing rain and colder temperatures back into the Ohio Valley.
In addition, it appears the colder than average temperatures will try to make a return for mid/late next week into early February as some of the MRF (medium range forecast) models develop a new polar vortex (PV) in central Canada with the mean trough from the PV down into the central US.
A snowstorm late next week ?????????? The GFS is fairly bullish with that prospect and has consistantly had a storm moving across the Eastern half of the country the past several runs - The problem.... the details (i.e. exact track / thermal profiles etc...) of the MRF guidance this far out is usually not that good - as a matter of fact it typically blows beyond 5 to 7 days....
We'll continue to watch and keep you updated, stay warm gang.
