It looks like most areas received a light coating of snow this morning. Mostly light snow showers will come and go through the day. Some spots could see an occasional burst of moderate snowfall, but for the most part, snowfall rates through today will generally be light. Even a light coating of snow on the road can create slick spots – especially on untreated roads.
We won’t see much in the way of snow accumulation today. The combination of higher sun angle and light snow should hold accumulation to around and inch or two.
On the temperature front, after a start this morning in the low-20s we will gradually see temperatures warm to around freezing this afternoon. Colder air will filter back in later tonight and most neighborhoods will drop back to the low-20s by sunrise Friday.
Chances for light snow/flurries will persist into Friday as the center of the storm system pulls northeast and exits and drier air moves into the region. Friday will bring a colder day than today with afternoon temperatures in the mid/upper-20s. An upper-level disturbance will travel across the Valley Friday night and I can’t rule out a brief light snow shower. The odds favor a dry forecast, though.
Dry conditions will set up for Saturday and Sunday as high pressure builds over the region. Saturday will remain particularly cold. Temperatures locally won’t do much better than low/mid-20s for the afternoon high. Clearing skies Saturday night will allow for radiational cooling in a big way resulting in nighttime lows falling back to the single digits.
Temperatures are expected to moderate on Sunday. We may actually warm to above freezing to around the upper-30s as warm air flows into the area ahead of a cold front. Average highs around this time should be around 42°.
Low pressure will travel into the Great Lakes region out of Colorado Sunday night into Monday bringing precipitation back to the forecast. Initially, temperatures will be cold enough to support snow. Winds out of the south ahead of a cold front will pump warmer air into eastern Ohio allowing a changeover to rain or a rain/snow mix as temperatures warm in the afternoon.
High pressure returns to dry things out for Tuesday and Wednesday. Even with the prospects of a messy weather period at the start of the work week, there is a positive aspect to the mid-range forecast. Temperatures closer to normal will likely set up next week allowing us to finally get out of the deep freeze. Potentially, some locations could warm to the mid-40s for at least a couple of days. Nighttime lows could very well hover around average as well.
Thanks for keeping up with the local weather with the Valley’s only local weather resource. Be safe out there.
