The frigid arctic cold will continue into Wednesday, and the snow is expected to continue into Tuesday evening, although it is likely to be lighter and intermittent on Tuesday.
I’m still expecting two-day storm total accumulations through Tuesday to be in the 3-6 inch range for the Front Range urban corridor and eastern plains. But 5-9 inches is a more likely range in the foothills and in some areas immediately along the foothills like Boulder, Golden, and the far south and southwest suburbs of Denver. The clouds might thin enough at times on Tuesday to make the sun dimly visible, but don’t expect that to add much to the maximum temperature!
Temperatures will continue to drop Monday and be near zero around nightfall. Minimum temperatures on Tuesday and Wednesday mornings are likely to be mainly in the -5 to -15 range. Wednesday morning may be slightly less cold than Tuesday in the foothills, but in the lower elevations, Wednesday may be the coldest morning, especially in river valleys. On Tuesday the maximum temperature will probably be within a few degrees of zero. Expect to get above 20 on Wednesday.
The record low for Denver and Boulder on Tuesday morning is -11, and there is a chance we will reach that. The record low for Denver Wednesday morning is -19 and for Boulder it’s -18, and there is less chance for reaching that.
One record that is likely to get shattered is the record low maximum temperature for Tuesday, which is 8 for Denver and a balmy 16 for Boulder.
New Year’s Day:
A large piece of this cold storm system will break off and move into the desert southwest bringing cold weather there too. It is expected to move eastward Thursday and there is a slight chance that it will be close enough to bring a little bit of clouds and light snow to the Front Range on New Years Day. There is a better chance across southern Colorado.
