Administrators NorthGeorgiaWX Posted January 8 Administrators Share Posted January 8 MD 0011 CONCERNING BLIZZARD FOR SOUTHEAST CO...RATON MESA OF NORTHEAST NM...FAR WESTERN KS Mesoscale Discussion 0011 NWS Storm Prediction Center Norman OK 0527 AM CST Mon Jan 08 2024 Areas affected...Southeast CO...Raton Mesa of northeast NM...far western KS Concerning...Blizzard Valid 081127Z - 081730Z SUMMARY...Heavy snowfall rates around 1 inch per hour are expected to begin between 13-15 UTC on a localized basis. Surface gusts will rapidly increase this morning (into the 35-60 mph range) and coincide with more widespread 1 inch per hour snowfall rates. These conditions will lead to substantially reduced visibilities and result in blizzard conditions beginning during the late morning (15-18 UTC). DISCUSSION...Water-vapor imagery shows a powerful mid-level shortwave trough moving east across the Sangre de Cristos early this morning. Deep-layer forcing for ascent will continue to overspread the central High Plains as the column saturates early this morning. Light to moderate snow will transition to localized heavy snow (i.e., rates around 1 inch per hour) beginning in the 13-15 UTC period according to the latest SREF and HREF model guidance. Heavy snowfall rates of around 1 inch per hour will become widespread during the 15-18 UTC period as both upslope flow strengthens south of the Arkansas River and deep-layer ascent associated with the cyclone intensifies. Low-level flow is forecast to intensify markedly during the morning with 250 m AGL flow increasing from less than 10 kt to 50 kt while contributing to very strong gusts and substantially reduced visibilities. The strengthening of surface gusts into the 35-60 mph range is expected to coincide with the onset of more widespread 1 inch per hour snowfall rates and result in blizzard conditions during the 15-18 UTC period. ..Smith.. 01/08/2024 ...Please see www.spc.noaa.gov for graphic product...
