A minor trough works its way through the state today. Because of this we see more clouds around, and we also will push “pause” on our gradually improving temperature and sky condition pattern. Moisture today still looks minor, at a few hundredths to a tenth or two, but we are increasing coverage to closer to 70% of the state. This comes from the northern edge of moisture moving north. We think that today we have to at least allow for a chance of hit and miss moisture from US 30 southward. Remember, moisture will be very minor…but we just don’t dry very much today. The trough today also ushers in colder air, with temps colder than yesterday, and the return of NW flow. We get full sun back tomorrow and it stays Sunday. Temps tomorrow are chilly, but a bit warmer than today. Then for Sunday we see a huge move up in temps. IF we have any potential for an above normal day in the next 10 days, it will be Sunday. Clouds will start to build late Sunday afternoon and continue overnight.
Our next weather system arrives Monday. Rain showers break out over the state and continue into the evening. Cold air surges in behind the front, and we think that the cold air arrives while we are still dealing with some moisture, so we are keeping a chance of rain ending as snow overnight Monday night into early Tuesday morning. We are keeping threat of even minor accumulations low at this point, but will revisit any update early Monday morning right here, so stay tuned. Bitter cold air stays in control through most of the rest of the week. For the balance of Tuesday, after the morning snow shower or flurry potential, clouds will work to give way to sun, and we expect breezy conditions out of the northwest.
Partly sunny and very cold Wednesday, remaining cold Thursday. Temperatures will likely be well below normal for those days. The coldest model out there right now has some below zero temperature readings over parts of Ohio next Thursday morning. The map is at right. Even if we don’t quite reach these levels, we still likely are looking at the coldest air of the season today with this air mass. Late next week on Friday, we have clouds increasing, and that leads to our next system arriving overnight Friday night and continuing through Saturday. Moisture is pushing up from the south. WE can see liquid equivalent precipitation totals from .1″-.5″, and with cold air holding over the area, the majority of that looks to come as snow. Accumulations are likely, but we are holding off on snow totals until closer to the event. Coverage will be pushing 80% of Ohio between Friday midnight and Sunday morning.
Clouds give way to sunshine for Sunday the 15th. Temps moderate. Rain showers move across Ohio on Monday the 16th with potential of .05″ to .4″ totals and coverage of 70%. The system is done by Tuesday, and we stay dry for the rest of the period through Saturday the 21st. Our rain potential on the 20th has fallen apart this morning…we wont be surprised if it re-forms, but the low looks organized and track uncertain at this time.
