San Juan Mountains Weather Forecast ~ Sunday, March 25, 2018 @ 07:20


Cooling temperatures on tap today with increasing winds and cloudiness building throughout the afternoon. There is low pressure Pacific energy moving onshore on the Oregon coast this morning and will begin pushing into the Great Basin and western Colorado later today through Tuesday night on southwest flow.

Unfortunately the San Juans will be out of the main flow of this storm which will favor the central and northern Colorado mountains. We could see an angry inch or two but really looks more like dust on crust.

Splitting energy off the main trough has a potential closed low dropping south of the 4-corners on Monday and could create some wraparound moisture Tuesday (maybe 3-6″) but it appears to be nearly bone dry so don’t expect much more than scattered convective snow showers fore most mountain terrain.   Another impulse on Wednesday will arrive on NW flow so again the San Juan’s will get skunked and only see some cloudy skies.
