Wow, what an event for the region! Accumulations of ice were a bit lower than forecast due to the faster onset of sleet. Then, the deformation band that I mentioned yesterday took shape right across the region, leading to heavy snowfall!
Overall, I give my forecast a “B” grade. I got the timing of everything mostly correct, however the deformation band threw a wrench in the forecast, which was kind of expected.
Totals across Marshall County seem to be in the 6-8″ range as far as total accumulations of both sleet and snow combined, however drifts of snow may be well over a foot deep. We should get an official snowfall map from the National Weather Service tomorrow.
The snowpack will complicate overnight low temperatures. If clouds can move out of the region, we’ll likely drop to the single digits, but the current forecast calls for some clouds and lows in the low teens.
Partly cloudy skies are forecast tomorrow as high pressure moves into the region. Highs will “warm” to around 23°. Stout northerly winds of 10-15 mph will make it feel like it’s in the low teens.
We’ll have to see how the snowpack influences temperatures on Saturday night as well. Lows may very well dip below zero. The NAM model suggests we may get as low as -6°!
That should wrap up this forecast and this winter storm. I’ll have a fresh forecast in the morning. Have a great night!
