December 31st – December 31st, 2018 – Another major winter storm is taking shape across New Mexico and southern Colorado this afternoon. Snow totals with this storm will be high in the northern mountains. Travel concerns will begin later this afternoon for I-40 west and especially I-25 north. What is unique about this storm is the long duration that is expected. The snow hole phenomenon in Albuquerque will be a huge factor due to the downslope winds. However, an enhanced surge of low-level and mid-level on Tuesday and Wednesday will allow for accumulations in the metro. Up to 2” are possible in downtown while accumulations of up to 6” are possible near Tramway.
The snow will continue into Wednesday before exiting the state by early Thursday. Driving will be dangerous across southern Colorado and most of New Mexico through Thursday morning. There should be a warmup by the weekend before the next system begins to impact the region.
