Weekend: Mountain snow, Mainly cool and dry plains

5:50 AM MDT, Friday, October 18, 2019

Friday and Saturday

You may notice it is unusually mild early Friday morning, but it may not warm up much during the day following a Pacific cold front. It’s not a strong front so temperatures today and Saturday should get into the 60s in the urban corridor. The front may bring a period of gusty west winds, and for the mountain areas expect some snow showers. If any of that precipitation survives east of the mountains, it should be in the form of a brief rain shower. Saturday should start out mainly sunny.

Saturday evening and Sunday

A strong storm should move across northern Wyoming and the Dakotas Saturday evening and Sunday and drag a strong Pacific cold front across Colorado. That one should result in snow along and west of the continental divide, maybe on the order of 6 inches at some of the high passes along with gusty winds.

For the foothills and plains there may be a few rain or snow showers, but most of the precipitation should remain near and west of the high mountains. The main impact for the foothills and plains will be cool temperatures and a period of blustery west or northwest winds.


Public talk about Boulder climatology on Thursday, October 24th

I will be giving a talk at the NCAR Mesa Lab at 6:30 PM on Thursday, October 24th. The Boulder climate station is in its 30th year. Official climatological numbers are typically 30-year averages, and this is the first time Boulder’s observations have been in one consistent location for 30 years. I will talk about the 30-year averages, extremes, and how those relate to the longer-term record.  DBAMS October 2019 Meeting Flyer – Kelsch
