BBS: TELESC.NET.BR Assunto: HVYSNOW: Probabilistic Heavy Snow And Icing Discussion De: COD Weather Processor Data: Fri, 27 Mar 2026 07:08:03 +0000 ----------------------------------------------------------- FOUS11 KWBC 270707 QPFHSD Probabilistic Heavy Snow and Icing Discussion NWS Weather Prediction Center College Park MD 307 AM EDT Fri Mar 27 2026 Valid 12Z Fri Mar 27 2026 - 12Z Mon Mar 30 2026 ...Western Great Lakes... Day 1... Cold air (850mb temperatures around -15C) over the western Great Lakes will support light snow across the region tonight as a mid- level shortwave moves through the region this afternoon/tonight. Amounts will be light (1-2") but could touch 4" over parts of the U.P. of Michigan where WPC probabilities are near 10%. ...Pacific Northwest/Northern Rockies... Day 3... Upper trough diving southeastward along the BC coast will move into the Pacific Northwest on Sunday, bringing some mountain snow to the Cascades and then into the northern Rockies along the Divide. Colder air will rush in behind the cold front, allowing snow levels initially near 2500-4000ft to fall to 1500-3000ft overnight Sunday into early Monday (Cascades) but remain around 5000-600ft over northwestern MT. This will get some light snow to the passes in WA, but probabilities for at least 4 inches of snow are greater than 50% above about 4000-5000ft (Cascades) and 6000ft over the Lewis Range. The probability of significant icing across the CONUS for days 1-3 is less than 10%.
