The State of the Atmosphere: Monday, November 16th, 2020

The next system we are tracking is one to impact our area Friday through the weekend. Until then, expect quite warm conditions - especially Wednesday when Denver will be near 70 degrees. During the past week, heavy periods of snowfall impacted the mountains and the metro areas benefited from a bit of snowfall also. In terms of percent of average, here is how the past week performed: Temperatures over the past week averaged cooler than a 'normal' week. Looking ahead to the upcoming week, we ha
Denver Forecast
Mild Friday, windy and chilly Saturday, then a warming trend
A quick update this morning to look ahead to the weekend and what looks like another period of mild weather back in the forecast as we head into next week. A fast moving system will bring a round of moderate snowfall to the high country tonight and Saturday, but mostly wind for Eastern Colorado. A few showers may spread east of the mountains on Saturday, but aren't expected to amount to much. The hourly planner for Denver shows a chilly day the chance we see some rain and snow showers around

October results are in, a look ahead through early December
With La Niña in control, we enter most of our forecasts with a drier and warmer than average bias – unless the PNA and NAO combine to offer a trough-favored pattern, which isn't the case through much of the next month. October was interesting in that we had enough significant cold over the plains for the eastern half of Colorado to have had near and colder than average conditions. Precipitation was just as expected... lacking in most areas: Going forward, we believe that there may be some re

Snowfall totals exceed expectations in some areas, as summer in November comes to abrupt end
Yesterday's snow piled up a bit higher in some spots than we anticipated in our forecast issued on Sunday. Yes, we said some areas could pick up 2" or so, but even with that mention we came in a bit low for Boulder and Fort Collins it seems, thanks to a couple of bands of moderate snowfall Monday afternoon and evening. Our gamblers definitely perked up a bit yesterday from where they were, but still the 3" totals a few areas were well outside the most probabilistic outcome from Monday's event.

The State of the Atmosphere: Sunday, November 8th, 2020
As we discussed in our last update , the weather system that has brought wind and isolated showers to the Front Range and Eastern Colorado last night and today has delivered some big time snow to the mountains of Southwest Colorado. The heavier snow we saw overnight, and the showers we're seeing across Eastern Colorado will come to an end this morning, before

Weekend system to bring chillier weather to Denver, and perhaps feet of snowfall to SW Colorado
Temperatures are forecast to drop this weekend – after days of record/near record temperatures – and some areas will see rain and snow, too. Yesterday, Denver set a record high for November 4th reaching 77°F (the old record was 76°F set in 1915), and also set a record warmest low temperature for the date of 47°F (the old record was 45°F set in 1999). We have several more warm days ahead of us before cooler temperatures return to the forecast. Let's look at the temperature animation showing th

Presidential Election Day weather history, Denver
Let's take a look at Presidential Election days going back in Denver's history. This year is the warmest voting day in Denver's history for presidential election years. DIA hit 79 Tuesday afternoon, making it one of two warmest Election Days on record including all presidential and offset election years as well.

Election Day forecast, 2020
Great job getting out and voting, Colorado. As of Saturday, nearly 2.5 million Coloradans had already voted in the 2020 general election. That's 86.7% of the total 2016 turnout ! Tuesday is Election Day, we hope everyone who hasn't yet voted has a plan to get out and vote – or a plan to drop (not mail!) your ballot at a drop-off box by 7 pm Tuesday.

Drought
The week's precipitation moved the needle only slightly
The snow and rain event earlier in the week is obviously great considering how few and far between precipitation events have been this year. This has been especially true since June-July when things really shutoff, but the storm this last week wasn't enough to erase deficits – just moved the needle in spots slightly. Let's look at the county-by-county precipitation that fell that fell th

Drought update and the outlook: October 29th, 2020
While the recent storms have brought moisture to areas that need it most, it won't be enough to reverse trends. Drought continues to hit the region hard, with expansion in Extreme Drought across Eastern Colorado since our last update , and more Abnormally Dry conditions popping up across Texas as well. Below is a look at the difference between October 13th and October 27th, 2020. While much unchanged, the in
Meteorology
Jet-enhanced banded snowfall: What is it, and how did it contribute to the October 25th snowstorm in Colorado?
One of our main mechanisms for snow producing storms along the Front Range is what we call upslope: winds that push up against the Rockies and create the lift needed to produce precipitation, which in the winter usually falls in the form of snow. For the northern urban corridor that's typically a northeasterly or easterly wind, but that differs depending on where along the Front Range you are located. With a classic cutoff low snowstorms, that upslope is deep – meaning we have strong upslope w

Snowfall totals as storm clears, cold lingers through Tuesday
What a great storm, if for no other reason than the 10 - 20" of snow that fell over the East Troublesome and Cameron Peak fires. Rarely does it seem a storm is able to deliver when we are in such need – but this one did, even if less moisture content than you might expect from an October storm. Along the urban corridor those north of Denver did best with snow totals this round, and this should come as no surprise [https://www.weather5280.com/2020/10/24/winter-storm-warnings-and-advisories-post

Storm Update: Snow continues across Colorado, bitter cold tonight
No real changes to the forecast. The snow is here, as is the cold, and frankly it's about time. At our station in Denver West snow has been on and off since about 5am. As of 10:30 am we had recorded 1.5" of fluffy snow, with light snow continuing. Up north we've seen a persistent snow band deliver upwards of 5" of snow to parts of the Fort Collins area, with good snowfall continuing there at this hour. This heavier band of snow will continue to drag south as the day progresses. By this eve

High fire danger through Saturday, then finally some snow is headed to Colorado
Yes, we'll be talking snow in today's update, but first... another day and half of windy weather, low humidities, and high fire danger to work through before the change arrives.

Winter outlook 2020 - 2021
An early season snow this September gave the illusion that winter may come early this year, much like it did in 2019. This was clearly not to be, with exceptional warmth and drought continuing to be the dominant weather pattern across the greater region. This, of course, should come as no surprise if you've been following our long-range outlooks over the last year or so. A
