Snow threat update

Jason Samenow @ 1:05 AM

*Morning update (10am) -- Snow lovers: The trend is not your friend*
Latest guidance continues to shift the track of this storm northward. Accumulations at the lower end of the 2-4" forecast (shown below) appear more likely and this forecast may need to be adjusted downward. Ice may be the most significant factor with this particular storm. Stay tuned for updates.

A light to moderate snow event appears likely late Sunday afternoon into Sunday night. However, guidance for the storm track has trended north, meaning this does not appear to be a major winter storm and the precipitation will likely change to liquid late Sunday night or early Monday morning.

Today, expect another cold afternoon (after a very cold start--teens to low 20s early in the am), with highs 35-40.

On Sunday, with temperatures in the 30s, clouds will increase, and some light snow will develop late in the afternoon or in the evening. There may be a burst of heavier snow between 8pm and 2am. The snow may mix with and change to sleet and freezing rain after 2am, and taper to drizzle by Monday morning. Right now it appears Presidents' Day will be on the gloomy side with occasional drizzle and highs in the low 40s.

Overall storm assessment

Storm Impact:

Travelcast (Sunday night):

Schoolcast (for Monday): Holiday, schools closed

The bottom line is that I expect around 2" inside the beltway, and 2-4" in the north and west suburbs. If the guidance continues to trend north with the storm track, just a burst of snow may occur (1" or so) before the changeover to a mix or rain. Alternatively (but less likely), the storm track could shift a bit to the south, which would increase amounts to 3-6" or so. I'll update my snowfall map tomorrow night, based on the latest guidance. (For comparison, here is AccuWeather's snowfall map.)
