Cool and unsettled through next weekend

Friday, October 23, 2015

An active jet stream has settled over our area and is forecast to persist through next week and the following weekend, bringing periods of rain and higher elevation snow every several days. After this storm clears the area later today, dry weather with seasonable temperatures are forecast for this weekend.

But a series of waves in the eastern Pacific will interact in a complicated manner and eventually push through another cold wave by Monday, bringing more precipitation to the area after the weekend ends. A trailing wave later Tuesday may bring the coldest air of the season into the Steamboat Springs area later Tuesday and into Wednesday, possibly producing some snowflakes in the Yampa Valley by Wednesday.

Brief ridging on Thursday should give us a break before another warmer Pacific wave takes aim on the California coast, bringing much needed precipitation to that area before moving across the Great Basin and possibly affecting us by Friday.

The inclement weather will be briefly interrupted around the weekend before another wave threatens our area with more precipitation by around Monday, The European ECMWF is forecasting a more southward trajectory for this storm compared to the American GFS, and may keep the storm too far south to bring precipitation to our area.

More seasonable weather returns during the weekend

Thursday, October 15, 2015

Our run of spectacular fall weather looks to be interrupted starting this weekend as the week-old storm that passed south of our area last weekend and spent some vacation time in Baja this week is forced eastward across the Great Basin by an upstream Pacific storm.

Before this happens, though, the current unseasonably warm and dry weather will persist through tomorrow and likely most of Saturday. As the lingering storm from last week crosses the Great Basin, it weakens considerably as it interacts with the current ridge of high pressure covering the Rockies, but will first spread high clouds over our area on Friday and then deeper moisture by Saturday, which should cool temperatures from their near-record highs.

There will be a chance of showers Saturday afternoon and evening as what remains of this storm passes over the area. By Sunday, the Pacific storm crosses the West Coast, and devolves into an unorganized storm system that will span the nearly the entire third of the North American continent as it barrels into and around the ridge.

While the details will almost surely change in such a complicated forecast, unsettled weather with mostly seasonable temperature will persist from Saturday night through Tuesday, with the best chance of showers currently forecast for later Monday and Monday night as some energy moves over the area.

Some of this storm gets left behind in the southwest around midweek, leading to a nice break in the weather then. However, that storm paired with another storm approaching the West Coast by the end of the work week may threaten next weekend’s weather.

Spectacular weather for the next week

Thursday, October 8, 2015

A straightforward forecast for a change as the jet stream is forecast to stay north of the Steamboat Springs for the next week. There are a couple of dry waves traveling well north of us this afternoon and again Sunday afternoon, and we may get some cooling and increased winds from those systems. Otherwise warm and dry weather will grace our area through the most of the next work week.

Interestingly, the cutoff low to our south which brought the cool and showery weather earlier this week is forecast to move south and west, eventually ending up near Baja by early next week. There is modest agreement between the models that this storm will eventually be forced to the northeast across the Great Basin by a quick-moving storm in the eastern Pacific by midweek.

There will likely be interactions between the Pacific and Baja storms, with details becoming clearer as we head through next week. But it appears these two systems may threaten our warm, sunny and gorgeous weather by the end of the work week and for the following weekend.

A couple of fall storms timed for early this weekend and next week

Thursday, October 1, 2015

The above average temperatures of this early fall will continue through most of tomorrow before a storm currently off the California coast brings cooler temperatures and showers into the Steamboat Springs area later Friday.

This storm will be forced eastward from the coast as a second splitting storm currently in the western Canadian high latitudes takes its place along the West Coast by Saturday night. The first storm will bring a noticeably cooler airmass by Friday night, with showers developing ahead of and along the front by Friday afternoon or evening.

Saturday should start off dry and cool before there is a chance of light showers redeveloping in the afternoon and evening. The second storm will then develop into a closed low cutoff from the jet stream to our north around Sunday, backing our winds to the southwest and initially bringing some drying into the area for Sunday and Monday.

This second storm is forecast to move eastward or southeastward across the southern Great Basin on Monday, and will bring increasing moisture from the south over Colorado, similar to the active monsoonal pattern we saw for a lot of this summer. There may be a small chance of showers on Monday afternoon, but the heaviest rainfall is reserved if the storm moves over our area from later Tuesday through Thursday.

Models are struggling with the timing and position of the storm. A fair bit of uncertainty exists with how far south the storm eventually moves, with the latest European ECMWF favoring a more southern, slower and drier solution. If the storm takes a more northern track like the American GFS, showers may continue through Thursday and perhaps even Friday as the storm moves east of the area, leaving the classic-for-Steamboat cool, moist and unstable northwest flow.

Some ridging is forecast to occur behind the storm, bringing improving conditions for the following weekend.

Quintessential Colorado fall weather continues through the weekend

Thursday, September 24, 2015

The current warm days and cool nights reflective of this quintessential Colorado autumn weather will endure through this weekend, highlighting the spectacular fall colors.

Starting early in the work week, model differences make the forecast uncertain. All models have a Pacific storm currently in the Gulf of Alaska splitting, with the northern part of the storm moving north of the Steamboat Springs area late in the weekend. This grazing storm will drag some cooler and more seasonable air over the area by late Sunday or early Monday.

The American GFS insists on the southern part of the storm crossing the West Coast and bringing moisture into the Steamboat Springs area by Monday afternoon. The European ECMWF, on the other hand, has been consistent in keeping the southern part of the storm off the coast for the first few days of the work week and moving it towards our area by later in the week.

Because the GFS has been trending towards the slower and drier ECMWF the last few model runs, I expect this trend to continue, leading to only a slim chance of showers early in the work week.

The ECMWF does finally bring the southern part of the Pacific storm over our area later in the work week, so the weather around then and heading into the following weekend may be unsettled.
