Good Evening! We have had a couple of very nice late Fall days to melt the snow from the storm Sunday/Monday of this week. Now we are back into it with more winter weather on the way. Lets have a look at what’s going on!
WINTER WEATHER ADVISORY ON DECK – As mentioned in the last post, NWS Boulder has a Winter Weather Advisory set to go active at 3 AM tomorrow morning, lasting the entire day. We’ll see some snow starting to the north, and working south into and through the Metro. Let’s take a deeper dive.
PRE-DAWN AND EARLY PRECIP? – I am expecting clouds to thicken as the night progresses, and areas between Fort Collins and the state line could see some drizzle as soon as 3 AM. The tricky part of this forecast is, “does it become freezing drizzle right out of the gate or no?” I think no, that precipitation drops further into the northern end of the Metro by about 6 AM. It should be closer to then that stuff starts changing to freezing, and snow could be falling as soon as 8 AM in Denver proper. Forecast data is coming in with varying speeds and temperature profiles, so confidence in an exact time snow will start is low. All data does say that we’ll be snowing by noon tomorrow though!
WHERE AND HOW MUCH? – NWS Boulder has the Winter Weather Advisory up all the way down to the Palmer Divide. It will be close but my money says if you gets south of say, Castle Rock or Larkspur, you should be fine, as in any snow there should be of little consequence, if you even see any there. This appears to be a northeast quarter of Colorado affair, with the heavy stuff up in the high country! Metro area, dusting to an inch. Foothills, 1-3″, locally higher amounts possible, especially as you go north. High country, 4-8″ unless you’re around Leadville or Estes Park, then you might see double digits up to a foot!
Here’s my forecast for Denver and vicinity including Thornton and Littleton:
Tonight – Clear to start, increasing clouds and becoming chilly, some rain or perhaps drizzle late. Lows near 28, winds northerly 5-10 MPH. Winter Weather Advisory in play after 3 AM.
Saturday – Cloudy skies, any rain will change over to snow by about 11 AM, high only 34. Winds N 5-10 mph.
Sunday – Skies slowly clearing, warmer. High 43.
We’ll have more for you later and a six day planner as well!
