Brief periods of moderate to heavy snow, 30+ mph gusts, and rapidly reduced visibilities are all possible.\nDiscussion: Convergence along a surface cold front has increased over the past few hours as a 100+ kt 500 mb jet overspreads this boundary. As a result, a snow squall has developed. Reduced visibilities below a quarter mile have been observed, along with brief instances of moderate to heavy snowfall rates and gusts over 30 mph. The snow squall is expected to persist across portions of the northern Appalachians over the next few hours as the parent mid-level trough continues to amplify over the region, further increasing deep-layer ascent and the strength of the leading line in turn. Within the strongest portion of the snow squall, a rapid onset of 0.5-1.0 inch/hour snowfall rates could occur, with a rapid veering of the surface winds to the northwest at 15-25 mph, with higher gusts likely. Visibilities may drop below a quarter mile where the stronger winds and higher snowfall rates coincide.\nIssued: 2026-07-31 07:08 UTC\nIngested: 2026-07-31 07:09 UTC\nDiscussion: https://www.spc.noaa.gov/products/md/md0001.html"
