Mesoscale Discussion 0062 NWS Storm Prediction Center Norman OK 0208 PM CST Sat Feb 01 2025 Areas affected...Portions of central and northern Minnesota Concerning...Heavy snow Valid 012008Z - 020015Z SUMMARY...Moderate to locally heavy snowfall is expected to develop across portions of central MN and the Northland through late this afternoon. Snowfall rates exceeding 1" per hour will be possible. DISCUSSION...Latest observational trends, including shallow convective elements in visible satellite imagery, increasing snowfall rates, and decreased visibility, suggest heavier snowfall potential is materializing across portions of central MN and the Northland this afternoon. A stout low-level jet, and to some extent DPVA associated with an upstream shortwave trough, is supporting enhanced ascent across this region. As the low level flow slowly continues to veer, isentropic ascent should become maximized within the outlined area where it will be juxtaposed with higher moisture content through the DGZ and aloft. In addition to the heavier rates, surface winds near 15 to 20 kt will aid in reduced visibility through late this afternoon. ..Barnes/Hart.. 02/01/2025 ...Please see www.spc.noaa.gov for graphic product...
