900 mb temperature, omega. 950 and 850 mb wind. Valid 2/5 09z.
Notes:
This model forecast, valid at 09 UTC on the 5th, shows 900 mb temperatures above -20 degrees C in a band co-located with a band of maximum upward vertical motion (shaded). This band of intense upward vertical motion and high temperatures can be thought of as the model’s approximation of the snow band. The forecast sounding point shown in the previous few slides was south of the model forecast band at this time, and therefore was colder than -20 degrees at 09 UTC.Slide 19
