Snow in the Valley will be generally pretty light through this evening. The snow that’s occurring is lake effect snow showers coming off Lake Erie. These will gradually subside as our storm system pulls farther northeast tonight.
Again, I can’t rule out a squall or burst of briefly heavier snow in neighborhoods across the north. But for the most part, additional accumulation locally will be light tonight as dryer air begins to move in behind the storm. Additional accumulation will be an inch or less through tonight.
Remember, this isn’t over yet. A Winter Weather Advisory remains in effect for area counties until 7:00 AM Wednesday.
Now that the winter storm is winding down let’s take a look at what we can expect weather-wise in the Valley for the rest of the week.
WEDNESDAY AND THURSDAY
High pressure will gradually build over the region on Wednesday bringing an end to any substantial snow chances early in the morning. Clouds will this as the day progresses allowing for a nice but wintry afternoon. Cold air following our storm as well as snow on the ground will keep temperatures in the upper-30s. A westerly breeze will make it seem even colder.
As skies become mostly clear Wednesday night, temperatures locally will cool to the low-20s.
Thursday will be a cloudier day thanks to some high-level cirrus but it will be a few degrees warmer with highs in the low-40s.
FRIDAY AND THE WEEKEND
Uncertainty creeps back into the forecast as we enter the weekend. Once again, a couple of weather systems will likely merge into one stronger system Friday night then track across the Great Lakes over the weekend. There is no consistency between model runs which makes it difficult to even begin to build a decent forecast.
For now, I’ll include a slight chance for precipitation Friday night. This could be a combination of rain mixed with snow before changing to all snow early Saturday. Saturday looks to feature clouds with an upper-level low pressure system developing. Sunday also looks dry with a potential for a return of rain and snow chances Sunday night.
Honestly, if you have weekend plans you will just have to wait for a better forecast. The models will eventually work things out but it’ll take some time.
An upper-level ridge will build after the weekend to bring generally quiet weather to start next week.
