::: Drier and milder today/ Cooler with showers and some snow Saturday through Monday/ Milder with more sun Tuesday and Wednesday :::
DETAILED SUMMARY for the week -> Updated for Friday, May 17... Today - We have a slightly unsettled southwest flow aloft due to northwest US low pressure. This southwest flow should be mostly dry, but enough moisture lingers for very isolated showers and thunderstorms mainly along the divide. Plenty of sunshine is expected.
Saturday through Monday - A fairly cold low pressure system from out of the northwest US moves in with some upper level energy across the area, and a moisture increase, for increased clouds and showers, plus a shot at some mostly light accumulating snowfall mainly above 10,000 feet, and mainly for northern areas. Saturday night we see snow levels drop as 1 weather disturbance and a cold front pass through, for light snow to 8,000 and 9,000 feet. Sunday and Monday become a bit colder than that, with snow to lower elevations, and some snow accumulations.
Tuesday and Wednesday - High pressure ridging builds in some, with mostly sunny skies developing on Tuesday, and the same sunny skies but warmer temperatures on Wednesday. An even colder low pressure system develops across the northwest US, and this one looks quite unseasonably cold. CM
