Subj : HVYSNOW: Probabilistic Heavy Snow And Icing Discussion To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Tue Oct 22 2024 07:12:47 FOUS11 KWBC 220712 QPFHSD Probabilistic Heavy Snow and Icing Discussion NWS Weather Prediction Center College Park MD 312 AM EDT Tue Oct 22 2024 Valid 12Z Tue Oct 22 2024 - 12Z Fri Oct 25 2024 ....Greater Yellowstone... Day 2... A rather positively tilted trough extending WSW from southern BC closed off into a mid-level low today west of WA. This low then opens into a compact trough and ejects east Wednesday with the H5 trough axis crossing greater Yellowstone late Wednesday night. Snow levels in the moisture ahead of this wave are 8000-9000ft. The only snow probs for >4" in the WWD forecast period are on Day 2 and in the 20-40% range over the northern Absarokas in MT and for the Tetons. There is about a 10% risk for 6" in the Red Lodge portion toward Beartooth Pass. The probability of significant ice across the CONUS is less than 10 percent.
