Forecast Discussion:

Our small storm is underway Wednesday pm (Figure 1 is the radar from 7:40 pm). As of 10 pm, we only have a dusting outside, but a bit more may fall before 1-2 am.

Figure 2 shows that down slope will cut off the precipitation around 2 am at the latest. Your car window and the roads might be slick and icy in the morning, but there shouldn't be anything to shovel.

Figure 3, the HRRR model shows that through 11 am, we could get a dusting to 1/2 inch. Figure 4, the GFS, also shows the remaining hours of the storm giving us a coating or a bit more of snow.

The longer range forecast:

Starting tomorrow, we'll try to figure out how much rain/snow comes in Friday night. Normal high temperatures now are 52°F. We'll be a bit below normal for the next 10 days. That storm next Monday/Tuesday? We'll talk about that after the next storm, Friday, has passed.
