Heavy Snow Forecast Discussion
000 FOUS11 KWBC 261915 QPFHSD Probabilistic Heavy Snow and Icing Discussion NWS Weather Prediction Center College Park MD 315 PM EDT Fri Apr 26 2024 Valid 00Z Sat Apr 27 2024 - 00Z Tue Apr 30 2024 ...Great Basin into the Rockies... Days 1-2... A mid-level shortwave and upper jet will continue to carve out an anomalously deep trough over the Southwest, with a closed low developing over the Four Corners tomorrow. This will bring widespread high-elevation snow from the Sierra to the Rockies, with locally heavy accumulations expected. Areas more likely to be impacted by heavy accumulations include the western Wyoming ranges. Easterly winds sandwiched between a mid-level low moving through Utah and high pressure over Montana will combine with favorable upper forcing to support heavy snow this evening into the overnight, especially along the Wind River Range (above 9000 ft). WPC PWPF shows 50 percent or greater probabilities for accumulations of a foot or more along the favored terrain. The central Rockies, from the Medicine Bow Mountains south along the Front Range, will likely be impacted as well. As a mid-level center develops over eastern Colorado, upslope flow along with left-exit region upper jet forcing will support heavy snow across the region beginning overnight and continuing into late Saturday. For areas above 8000 ft, probabilities for accumulations of a foot or more are above 50 percent. ...Pacific Northwest... Day 3... While unsettled weather is expected across the region through the period, an upper-level shortwave associated with a low sliding southeast from the Gulf of Alaska and the northeastern Pacific will move across the region on Monday, driving snow levels down and increasing the coverage of accumulating snows across the Olympics and Cascades. This includes the Cascades passes, where WPC PWPF indicates that at least a few inches of snow can be expected on Monday. The probability of significant icing is less than 10 percent. Pereira $$
