Steamboat Discussion

Updated Saturday September 22, 2018

Today we expect mostly dry and warm conditions under mostly sunny skies and stronger high pressure ridging, with some breeziness mainly on the upper mountain, and in the afternoon in Aspen. 

On Sunday we expect warmer temperatures and increasing winds as low pressure approaches from out of the northwest US. This system will drop some snow on the high northern Rocky Mountains. Sunday evening and overnight we expect clouds to increase and scattered showers to develop across western and northern Colorado, with showers in Aspen. 

Monday clears out with cooler temperatures and northwest breezes as strong and cold low pressure affects the upper midwest and east, while high pressure builds out west, and Colorado sits in between. Breezy and mostly dry conditions are expected. 

LONGER RANGE: After the 25th we may see an increase of moisture and instability, aided by a dissipating Hurricane off Baja California, which has its remnants carried across Colorado. This may last a few+ days, for isolated to scattered thunderstorms and possibly some good soaking shower in favored areas, otherwise we are looking dry with stronger high pressure ridging and warmer temperatures. After the first few days of October (warm), a cold system may move through with our first real, measurable, 9,000 foot or so snow level, snow of the season. CM
