Snow starting falling as forecasted early this morning as a trough of low pressure pulls moisture into the area on southwest flow. The San Juan Mountains have some nice new snow numbers this morning while we’ll be seeing our share a new snow as snowfall rates look to pick up around 9:30am this morning. The most recent weather models show the low pressure trough sagging a bit further south and east than previous forecast discussions, taking some of the best moisture and weather dynamics with it. That takes some of the excitement out of my sails and adds in a little bit of uncertainty in estimated total snowfall numbers as models are still forecasting some nice total snow numbers in our area for Sunday and Monday. So we’ll have to wait in see how it all shakes out. After this morning pulse of snowfall we’ll likely see a decrease in snowfall rates this afternoon, before another pulse arrives after dark this evening and winds becoming more westerly to northwesterly. A third pulse of snowfall is forecasted to arrive mid-day Monday favoring Central and Northern Colorado as winds continue from the west to northwest. Wednesday through Friday will bring dryer air as we sit in cool northwest flow between low pressures to our East and West. The next system moving across the US towards the end of the week looks to mostly miss Colorado and dive even further south.
