Update, 5:15pm - The winter storm we have been watching intently continues on course and has actually sped up slightly. This leads to a greater likelihood of enough snow to make the morning commute a bad one and the possibility to school cancellations.
Snow is expected to begin across much of the metro area by 11:00pm with the greatest intensity between 2:00am and 8:00am. During this period as much as 4 inches may be on the ground with an additional inch or two possible during the day tomorrow.
As with last week’s storm, the Arctic temperatures are the big story with this storm. Temperatures are going to drop overnight and be down to 6 degrees by 7:00am and they will drop slowly during the day to around zero by 6:00pm.
A Winter Weather Advisory will go into effect at 11:00pm tonight and run through 5:00pm tomorrow. Roads are going to become icy and snow packed and travel may become hazardous.
Given the timing of the storm tomorrow morning’s commute could be a bit dicey so you will want to plan accordingly. Further, given the bitter cold temperatures, there is the possibility that area schools will cancel classes tomorrow so parents will want to plan accordingly.

Original story, 6:22am - You might as well let your car stay dirty for at least a couple more days as yet another winter storm is set to impact Thornton tonight and tomorrow. A Winter Weather Advisory has been issued and we will be seeing a decent shot of snow and bitter cold temperatures tomorrow.
For the kick off of the workweek it will see highs and lows near seasonal norms for the date. High temperatures today will be around 44 degrees under partly sunny skies with an overnight low of 11 degrees.
A winter storm system will begin impacting the high country today and it will begin working its way east and onto the plains late this afternoon and into the evening hours. We may see some light snow as early as 5:00pm but anything early will be scattered and late. The real impact comes during the overnight hours and into tomorrow.
Snow is expected to increase in coverage and intensity beginning around 11:00pm in the Denver area and lasting through most of tomorrow. Before dawn on Tuesday we may have a few inches on the ground with the heaviest periods of snow occurring from 3:00am to 9:00am. Tomorrow morning’s rush hour commute may be a rough one so plan accordingly.
Total snowfall accumulations in the metro area will be between 3 and 6 inches by the time the event ends Tuesday night. Here in Thornton we are likely going to be at the lower end of that range. Areas to the west and south in the foothills and along the Palmer Divide may receive up to 8 inches.
Accompanying the snow is a return to Arctic cold temperatures. Daytime highs temperatures on Tuesday will only be around 12 degrees and that will actually be dropping as the day progresses. Overnight lows tomorrow night will be below zero.
The National Weather Service has issued a Winter Weather Advisory for snow for most of eastern Colorado. The advisory goes into effect at 11:00pm tonight and runs through 5:00pm Tuesday.
The good news in all of this is that the storm will be short lived and we will start a warm up that is expected to last through the weekend. Temperatures on Wednesday and Thursday will still be below normal but we will see a return of the sun. Friday, Saturday and Sunday should see temperatures at or above normal.
