Today we have cold air parked right over the top of the state as high pressure moves across Indiana. This high will try and slide off to the east and slightly south tomorrow, allowing west winds to develop, followed by southwest winds for Friday. That means we should see gradual improvement in our temperatures as we finish the week. Today will still face a slow grind up from some single digit and subzero temps this morning. However, there is a much better chance of seeing widespread sun across the state today, versus what we saw yesterday.
West winds tomorrow take temps closer to normal, but it will take into Friday to see a fully normal temperature profile statewide. We expect highs to approach and exceed freezing on Friday. With the full on southwest winds, Saturday will likely be the warmest day of the next several, with temps a good 10-20 degrees above normal. Still, we should fall short of last week’s mild push. Sunday would have the potential to be just as warm as Saturday, if it were not for the clouds that we expect to fill on over the state.
Our next system is delayed some this morning. We still expect plenty of clouds over the state for Sunday with scattered, hit and miss light rains. Moisture totals will be a few hundredths to a tenth or two maximum. But, it will lead to a damp feel overall. Still, we think heavier rains will hold off until later on. Coverage of the light action Sunday will be 60%.
The cold front arrives here late Monday night and lingers into Tuesday. We see strong south winds averaging 15-30 mph as the front moves in. Rain totals are unchanged in our forecast this morning at .25”-.75”. Coverage will be 80% or better. This forecast has rains delayed a good 12 hours or more from our previous forecast Tuesday. The map above shows potential storm total rains for the Sunday-Wednesday morning period.
The rest of next week sees colder air push in. However, a major cold air blast is not likely. We think the cold air will be good enough to trigger some light snows over the state (wet snow, but still more snow than rain) Tuesday night into early Wednesday. This will mostly be north of I-70, and will be most prevalent in the northeast quadrant of the state. A better front moves in for Thursday, bringing liquid equivalent precipitation of a .1”-.5” over 70% of the state. This moisture can come as rain, wet snow or a combination of both. The best snow chances will be later Thursday afternoon in central and northern parts of Ohio.
Behind that minor wave, we still have a strong front on the way for the 28th as we start off the 11-16 day forecast period. This front has rain potential of half to 1.5” and coverage at 80% of the state. The timing of the cold air is still up for some debate, so at this time we have to leave our forecast to include rain, snow and a mix of the two. However, we do have colder air returning behind that system, and it will be cold enough to make our next system, one for the turn of the month on February 1, come as snow, and it looks to have excellent coverage with at least a half an inch of liquid to worth with.
