Temperatures are around fifty degrees under mostly cloudy skies with continuing gusty winds in the Steamboat Springs area late this Thursday afternoon. But the winds will gradually decrease and temperatures will rise each day through the weekend, making Sunday the nicest day with temperatures around seventy degrees under sunny skies and relatively calm winds.
A dry cold front barreled through our region last night, dropping the afternoon high temperatures today more than twenty degrees from our over seventy degree Wednesday. The mostly cloudy skies today will switch to be mostly sunny on Friday as temperatures warm about ten degrees towards our average high of 63 F behind the departing cold front.
Several weather disturbances will graze our area through Saturday, but they have all weakened and moved further north since my forecast from last Sunday, so no precipitation is expected. Fortunately though, their further north trajectories also mean gradually decreasing winds on Friday and Saturday, along with increasing temperatures as a ridge of high pressure moves through the West this weekend. This does not mean no wind, though, so expect afternoon breezes on both Friday and Saturday, with temperatures on Saturday rising about five degrees into the mid sixties, along with some increasing cloudiness through the afternoon and evening.
Sunday looks to be the warmest day of the weekend with temperatures rising another five degrees toward 70 F under sunny skies, with thankfully very little wind. More of the same is expected to start the work week as the ridge of high pressure moves overhead.
A couple of weather disturbances may bring some unsettled weather to our area around Tuesday and Wednesday of next week, though these are currently looking warm and modest at best. So enjoy the beautiful weekend, and check back Sunday afternoon for my next regularly scheduled weather narrative where I’ll discuss the precipitation potential for next week.

The Steamboat Springs area is seeing temperatures around sixty degrees under partly sunny skies with breezy winds from the west early this Sunday afternoon. A grazing cool front will knock temperatures back about ten degrees or so on Monday along with chances for showers tonight and early morning. But winds will turn to be from the southwest starting on Tuesday as sunny skies and warming temperatures persist through midweek ahead of a broad storm system to our west. The weather then turns unsettled by Thursday and lasts into the weekend as parts of that storm system pass nearby or overhead.
The eastward progress of a broad and cold storm system currently extending from the Aleutian Islands to the Dakotas is being blocked by a ridge of high pressure over the Mississippi Valley. Some energy ejecting out of that storm system brought a grazing cool front through our area yesterday afternoon which produced almost six inches of snow near the top of the Steamboat Ski Resort and almost a half inch of rain in the Yampa Valley by this morning.
Our wind speeds are forecast to stay elevated for much of the next week as the storm to our west reluctantly moves eastward. Another grazing cool front is forecast for tonight, and while there may be some snow showers at the higher elevations and rain showers down low, possibly mixed with snowflakes, it’s main effect will be to lower high temperatures to around ten degrees below our average of 61 F on Monday.
The storm system is first forecast to deepen along the West Coast through midweek before some cold air sourced from Siberia eventually gets pieces of the storm system moving eastward. The southwesterly winds ahead of the storm will keep dry and warm air from the Desert Southwest moving overhead on Tuesday and Wednesday, so look for mostly sunny skies and high temperatures warming into the sixties on Tuesday and possible the seventies by Wednesday, which will be the warmest day of the week.
Also by Wednesday, that cold air from Siberia will be moving across the Gulf of Alaska and is forecast to move some of the western storm eastward, bringing an initially dry cool front through our area on Thursday. There may be enough moisture for some showers by Thursday afternoon or overnight, though weather forecast models have trended less optimistic with those chances over the last few days.
The Siberian part of the storm is forecast to take a more northerly track through the Pacific Northwest and Intermountain West, but looks to be close enough to keep cool weather around for Friday and Saturday. There is weather forecast model disagreement on precipitation potential, though at this point the American model does have a chance of snow Friday night or Saturday, possibly down to the Yampa Valley floor.
Enjoy the warming but windy springtime weather through midweek, and I’ll have an update on the coming weekend weather in my next regularly scheduled weather narrative on Thursday afternoon.

After a rainy start to the day, skies have cleared and temperatures have warmed into the mid-fifties in the town of Steamboat Springs this Thursday mid-afternoon. Temperatures will further warm into the sixties on Friday and Saturday as winds increase from the west and southwest ahead of a grazing cold front timed for Saturday afternoon or evening. Temperatures will be knocked back by about ten degrees on Sunday, though it is not clear if we see a couple more grazing cool fronts on Sunday and Monday nights.
Though town saw rain showers this morning, snow was observed on Mt. Werner, with two day storm totals of around 5” at mid-mountain and 7.5” up top. While this has not significantly added to our snowpack, it has at least arrested the seasonal decline for a couple of days, with the Yampa-White-Little Snake basin showing the current snow water equivalent as being 89% of the 30 year running mean.
An expansive area of low pressure currently over the entire Gulf of Alaska is forecast to evolve through the weekend as cold air from the north and northwest interacts with approaching Pacific moisture and energy. Weather forecast models have trended deeper and slower with the bulk movement of the low pressure area; indeed the mid-weekend storm that looked far more promising only a few days ago is now forecast to stay mostly to our west through the weekend.
Many waves of moisture will move through this area of low pressure through the following week, with some strengthening the system in place while others move through. One wave currently crossing the Pacific Northwest will move to our north on Friday and have no affect on our weather, but the next one looks to drag a grazing cold front through northern Colorado later Saturday afternoon or evening. Ahead of that, high temperatures warm into the sixties on Friday and Saturday, around five degrees or so above our average of 60 F, with mostly sunny skies on Friday giving way to a mix of sun and clouds on Saturday.
Winds from the west will pick up on Saturday as the cold front approaches, with the best chance of showers centered around Saturday night. It is not clear if some of the cold air filters in Saturday afternoon or waits for the evening, but the system should be warm enough for snow accumulations of 1-4” to be confined to the higher elevations by Sunday morning.
A couple more waves are forecast to pass through the system on Sunday and Monday nights, though it is not clear if they will be close enough to do much more than knock high temperatures back into the fifties along with a chance of some passing showers, most likely on Sunday afternoon and evening.
What seems to be clearer, however, is that the bulk of our storm to our west will stay to our west as it is reinvigorated by some cold air from Siberia during the work week. This should lead to more wind and temperatures reaching into the seventies by midweek. A large amount of uncertainty exists after then, so stay tuned to my next regularly scheduled weather narrative on Sunday afternoon for a peek at what we may see after the midweek warming.

Temperatures around sixty degrees and cloudy skies are over the Steamboat Springs area this Sunday mid-afternoon. A couple of storms moving overhead tonight and Wednesday will bring good precipitation chances to our area with a small break on Tuesday between the storms. Beautiful springtime weather should return to close out the work week and begin the weekend though another strong wintry storm looks to arrive near the end of the weekend.
Two storm will affect our weather for the first part of the work week, with the first storm currently moving through the Great Basin and the second spinning in the Gulf of Alaska. Moisture and ascent ahead of the first storm has brought the cloudy weather today, with the cold front that is currently in eastern Utah expected to move through our area soon after midnight.
This storm will be warmer than our last storms, so while we may see some snowflakes in town overnight and perhaps early in the morning, accumulating snow looks to be confined to elevations above 8000′ or so. Numerous showers, some moderate to sometimes heavy are forecast along the front, and are expected to continue more intermittently in the favorable moist and unstable northwest flow behind the departing storm through the day Monday. I would expect 1-4” at mid-mountain between midnight tonight and sunset Monday, with a bit more near the top of the Steamboat Ski Resort.
We’ll see a break from Monday night through half of Tuesday as a ridge of high pressure quickly moves through the area ahead of the next stronger and colder storm. The cold front associated with the storm looks to pass through our area Tuesday afternoon accompanied by rain showers in town and snow showers at the higher elevations.
But the storm is cold enough to switch the rain to snow in town overnight and into Wednesday morning, and we may see an inch or two of snowfall accumulate on the floor of the Yampa Valley. Accumulations will be greater at the higher elevations, with 3-6” expected at mid-mountain between Tuesday afternoon and Thursday morning and more likely up top. Temperatures on Wednesday will be the coldest of the week, with high temperatures in town mired in the mid-forties, around fifteen degrees below our average of 59 F.
There is some weather forecast model disagreement on exactly when precipitation will end, with the European model hanging onto snow showers through Wednesday night while the American model has the storm over by then. In any event, they agree on clearing skies for a cool Thursday followed by lots of sun and warming temperatures to finish the work week and start the weekend.
There is agreement that another wintry storm will approach our area during the weekend, though it is unclear if the inclement weather arrives by Sunday or Monday. So stay tuned to my next regularly scheduled weather narrative on Thursday afternoon where I’ll be discussing the next likely significant opportunity to add to our seasonally diminishing snowpack.
