Subj : HVYSNOW: Probabilistic He To : All From : Mike Powell Date : Mon Feb 02 2026 09:41:08 FOUS11 KWBC 020713 QPFHSD Probabilistic Heavy Snow and Icing Discussion NWS Weather Prediction Center College Park MD 213 AM EST Mon Feb 2 2026 Valid 12Z Mon Feb 02 2026 - 12Z Thu Feb 05 2026 ....Pacific Northwest... Day 1... A weak shortwave and surface warm front will move through the region this morning with some light snow for areas mainly above 4000ft, with snow levels rising sharply later today. WPC probabilities for at least 4 inches of snow are >50% above 4000ft or so. ....Great Lakes... Day 1-1.5... Weak system will spread slight snow across the Great Lakes (1-2") today into Tuesday with some lake effect snow behind it, mostly over the U.P. of Michigan. There, WPC probabilities for at least 4 inches of snow are 20-40%. ....Northern Plains... Day 1... A shortwave in southern Canada will dive southeastward through North Dakota this morning, with generally light to locally modest snow along a thermal gradient. Some banded snow could develop and support a few inches of snow, and WPC probabilities for at least 4 inches are 30-70% over north central North Dakota. ....Ohio Valley, Central Appalachians, and Mid-Atlantic... Days 2-3... The shortwave over the northern Plains Day 1 (above) will dive into the Mid-MS Valley tomorrow morning and through the Ohio Valley tomorrow evening. At the same time, Gulf moisture will lit northeastward through the Lower MS Valley to yield some light snow on the northern side of the precip shield. WAA-driven snow is likely along the Ohio River Tuesday morning eastward to the central Appalachians tomorrow evening and into early Wednesday, also spreading to the Mid-Atlantic. Amounts will generally be light, but some upslope enhancement in eastern WV could yield a few inches of snow. WPC probabilities for at least 4 inches of snow are around 30-40% above 3000ft. 1-3" of snow is possible (>50% chance) from around Cincinnati eastward. Lower chances of just 1" are seen along the I-95 corridor from DC to PHL, but this could coincide with the Tuesday evening rush hour or possibly Wednesday morning depending on the speed of the system. Some light freezing rain or drizzle is also possible with this wave over KY/TN into VA/NC. Any ice is hazardous, but this could be more problematic than usual due to the recent winter storm(s).
