A cold front Saturday morning threatens to bring clouds and colder weather, but it’s looking like the real noticeable impacts will be from around the Wyoming border north and east into Nebraska. The Denver-Boulder-Fort Collins corridor will likely be on the milder side of a sharp temperature gradient, but it will be close by.

For Cheyenne expect some low clouds and minor snow accumulation Saturday and/or Saturday night, and cold Easter egg hunts Sunday morning.

For the Colorado Front Range I am 80% confident that the weekend will be dry, slightly cooler (but still mild during the day), with some cloudy intervals. That means there is about a 20% chance of it being 10-20 degrees colder than today’s 60s with clouds around.

Western slope areas will see less impacts from the cold front.

A disturbance moving through today (not really a storm system) and a cold front from the north will increase the chance for showery precipitation. It will be mainly rain in the lower elevations, except a changeover to snow in some of the heavier showers, and in areas that continue into the night. It should all be over before morning.

Expect 1-4 inches in the foothills, mountains, and Palmer Divide region. For much of the urban corridor there will probably be 0-1 inch, with some localized spots getting a couple inches.

It looks like we should have a nice mild spring day on Friday after this stretch of cool days.

I don’t have to tell you that a cold front came through last night and low clouds & some drizzle are around the area this morning. Although it may dry out a little today, more clouds and precipitation are likely later this afternoon and tonight, mainly from the Denver-Boulder area southward. A big storm is not expected.

Most likely accumulation:

3-6″ mountains & foothills of the Front Range, Palmer Divide, and the Pikes Peak region (mainly from Boulder County southward).

1-3 inches after rain initially for Denver & its western and southern suburbs, Boulder, Broomfield, and Castle Rock.

Little or no snow along and east of a line from DIA to Lyons to Fort Collins (including the northeast side of Denver and Longmont).

6:00 AM, Sunday, March 18, 2018

A fast moving storm system and cold front this afternoon will end the mild weather and bring some mountain snow, and some areas of rain changing to snow for the Front Range late this afternoon and evening.

For the Front Range foothills and plains it will be similar to the storm Thursday evening– brief but with some pockets of heavy precipitation and thunder. The difference is that this time it will be a few degrees colder, so in areas with the heavier precipitation the rain will probably change to snow and accumulate quickly before ending. Totals are likely to range from little or nothing in some areas to several inches that comes down fast in others. Watch for rapidly changing conditions.

After a cold start to the week, more springlike weather should begin working its way back on Tuesday in time for the equinox.

6:30 AM, Thursday, March 15, 2018

There is actually a chance for measurable precipitation late today or this evening along the Front Range urban corridor. It will likely be showery in nature, so some areas may get missed. The best chances are north of Denver, and there may be some pockets of briefly heavier showers with thunder. For the lower elevations it is likely to be mainly rain, but there could be some small hail or snow in some of the heavier pockets. Cheyenne has a better chance for some measurable snow. And snow is likely in the mountains.

This storm will pass quickly and mild weather is likely through much of the weekend. But a similar type of storm (except maybe a few degrees colder) may move into the area late Sunday.

11:45 AM, Friday, March 9, 2018

Since the weather won’t be too exciting, the change to Daylight Saving Time might be the most noticeable thing this weekend, and quite easy to forecast.

But there is some change in the weather on the way. A Pacific cold front will sweep through the state late tonight and Saturday bringing localized areas of snow to some of the high passes and mountains, mainly north of I-70. For the Front Range foothills and plains there is very little chance for precipitation with the front, but there may be a period of gusty northwest winds. Afternoon temperatures are likely to be about 10-15 degrees cooler than today, which still isn’t too bad. The dry weather should continue into Sunday. A storm passing south of the state on Sunday may bring some high elevation snow to the San Juans and Sangre de Cristos, but nothing major.

1:30 PM, Friday, March 2, 2018

The weekend should start out springlike Saturday, but a change colder and moister for the mountains is likely Sunday. The Front Range may not see the cooler weather until late Sunday.

Front Range foothills and eastern plains

Saturday should be another mild day, but high level moisture ahead of a Pacific storm may cause more cirrus clouds than we see today. The mild weather should continue into Sunday until the axis of the Pacific storm moves through late Sunday or Sunday night. Other than a chance for brief showery snow and rain, it should be mostly or entirely dry for the foothills and eastern plains. The most noticeable change may be the tendency for strong gusty northwest winds ushering in the cooler weather by Sunday evening.

Mountains and West Slope

After a mild Saturday the Pacific storm that is bringing much-needed rain and snow to California will begin to move into western Colorado Sunday. It will loose some moisture along the way, but there will likely still be enough to cause enough snow for wintry conditions on the high passes Sunday and Sunday night. Around 6 inches is probable in the high mountains and west-facing slopes.
