Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – January 28, 2019

Forecast Discussion:

The system is moving in late Sunday night. This post would normally go up as the snow starts (1 am) so I'll post early. The GFS (Figure 1) shows a coating to almost an inch possible before noon Monday. This northwest to southeast band shows up in the HRRR in the 5 pm update on the January 27th post has a very similar look. We'll see if it verifies.  The weatherunderground model (Figure 2) has under an inch over two days (Sunday pm to Monday am) which is also approaching an inch of snow for some folks around town.

The longer range forecast:

As cold air snaps the nation in two, we stay cold to chilly until the end of the week. Another very cold blast hits the central U.S. at the end of next weekend giving us a similar set up and another chance of snow (Figure 2). That's all I've got to say about that.  (-F.G.)
