Tuesday PM Update: Snow Back in the Forecast for Wednesday, Here's How Much

We're looking at another tricky snowfall forecast Wednesday as banded snowfall will likely lead to a lot of haves and have-nots when it comes to snow accumulation along the urban corridor and across Northeast Colorado.

NAM near-surface reflectivity forecast shows snow moving into Northeast Colorado midday Wednesday | Tropical Tidbits

As we discussed with our Insiders last night, snow totals from 2 - 4" will be most likely from Denver north to the state line and extending northeast up I-76. Within this area heavier snow bands will push your totals closer to the 4" mark (perhaps a bit more?) while those that miss on the heavier banded snow are likely end up closer to the 1" mark by Thursday morning. Bottomline: if you don't end up under this band we expect to form you're likely to be let down by our forecast... if you do end up under it, you should do just fine, and perhaps better.

Areas south and southeast of Denver are least likely to see high-end snowfall accumulation with this system, with low-end totals from 0 to a Trace for these areas. Can't rule out a heavier band getting further south than we anticipate so will leave 2" and 3" high-end totals for Colorado Springs and Castle Rock respectively, but best chance for accumulating snow should set up from Denver north.

For areas that do not end up under a heavier band of snow Wednesday, the COLD air expected to filter into Northeast Colorado will instead be the bigger story.

Here's a look at our forecast:

It feels like the Westminster/Broomfield/Boulder area is set to do best with this system. Of course that band could end up slightly south or north and change that, but if I were a betting man that's how I'd lean. We'll see how Denver does, it could be we ended up just south of the best dynamics. For Loveland and Fort Collins this one could be sneaky too, though by and large I'd favor the western areas here with less boom potential east.

Unlike our last event, the Euro remains one of the least excited models for snow potential tomorrow. So, we'll see how this works out... but what does it know anyway ;)

Timing and impacts
Best chance of snow for the area continues to look like it'll come midday Wednesday into Wednesday evening. Can't rule out some snow showers around late tonight and early Wednesday morning, but at the moment the commute that looks at greatest risk of being impacted by snow looks to be the Wednesday evening commute.

Temperatures will be quite cold too. While we have highs near freezing for Wednesday, those will likely come early in the day (perhaps tonight), before temperatures really nose dive Wednesday afternoon. Temperatures by your evening commute are forecast to be in the teens with areas of snow likely.

Wednesday night the snow gradually come to an end. In its wake temperatures will dip to near 0° for many areas across Northeast Colorado, with a forecast of just 3°F for Denver at the moment.

Thursday the sun should return, but temperatures will be cold. Highs only in the low 20s, with a chilly breeze.

We thaw out a bit for Friday and the weekend with highs in Denver back in the 40s Friday through Sunday.
