Cold air dominates the state the rest of this week. We are mostly dry here for the next few day and sunshine will make it look better than it really is, once you step outside. We won’t rule out the odd flurry in the north through Thursday, especially near the lake, but that will be a minimal occurrence. Temps will be a good 10-2 degrees below normal for this time of year and we will see our first sub-zero temperature readings overnight tonight into early tomorrow morning The coldest will be in a zone from US 30 down to I-70.
On the backside of the high we start to see south winds develop and that may lead to a bit of temperature moderation for the balance of Thursday and the first half of Friday. This will be ahead of our next fast moving clipper system for Friday late afternoon through Saturday. We have potential for 2-4 inches over 80% of the state. Strong north winds coming behind the system will keep lake snows in the forecast over NE Ohio through Saturday evening into Sunday, and we can add another several inches to snow totals there.
A second, stronger shot of cold air coming in behind that system on the heels of those strong north winds. Flipping the calendar into 2018 brings more cold air and light snow for January 1, but the light snow stays mainly near the lake. We could see a coating to an inch or two off the south shores of Lake Erie for the Holiday, but nothing anywhere else. The rest of the week looks brutal, with a potential string of 4 days back to back to finish the first week of 2018 in the single digits and below zero.
In the extended window, we could be looking at another major winter storm arriving around the 6th of January. Right now we see low pressure tracking directly across Indiana on a path from Little Rock AR to Buffalo, NY. This track currently would keep us out of the potential worst snow, but still has the potential to bring some significant winter weather. However we also point out this morning that its arrival is far enough out to allow for plenty of wiggle room on track, intensity, etc. We are keeping a close eye on it. These southwest to NE moving storms are trhe ones that always are the best threat for impressive weather. Behind that storm complex, cold air stays, and 2 clippers are possible, adding to the snow potential over the state. Temps remain below normal through Jan 10.
