Deep Days Across Oregon

Summary

Storm 1 delivered 12-40 inches of snow since Sunday. Scattered snow showers continue on Wednesday as we await Storm 2 moving in Wednesday afternoon. This storm and AR will bring a brief rise in snow levels, strong winds, and heavy wet snow. Snow continues on Thursday and Friday with lower snow levels with total storm accumulations of 1-3 feet. More light snow is expected on Saturday and Sunday.

Short Term Forecast

The next round of snow reports are in as of Wednesday morning with 12-40 inches of fresh snow since Sunday evening. The heaviest of these snow totals is around Mt. Hood with Timberline and Mt. Hood Meadows reporting 32-40 inches! Check out the snow reports below.

Forecast from Wednesday, February 28th through Friday, March 1st:

The next storm and atmospheric river (AR) approach Oregon on Wednesday afternoon and evening. Ahead of the AR, light snow will continue for the northern half of Oregon as snow levels rise throughout the day. Snow levels will rise to 5,000 - 5,500 feet, which will make a couple of resorts see rain at the bases.

The good news is that this warm wave will be brief, as the backside of the AR will drop snow levels back to around 2,000 feet on Thursday morning. Snow levels will continue to drop slowly on Thursday into Friday to 500 - 1,000 feet by Friday morning. A few valley areas could see brief snow accumulations with the drop in snow levels on Thursday night into Friday morning.

This change in snow levels will affect snow ratios and bring very different skiing and riding conditions as snow ratios lower to 6-8:1 Wednesday night, but then rise to 12:1 by Thursday morning and continue to rise to 15:1 by Friday or even higher. The first tracks on Thursday will have soft snow on top with a dense couple of inches below it with much softer snow on Friday morning.

Below is a look at the OpenSnow Blend of Model’s snow quality or ratio (black line) and 3-hourly precipitation rates (blue bars) @ Mt. Hood Meadows and Mt. Bachelor from Wednesday, February 28th through Saturday, March 2nd.



On Thursday, orographic snow showers will continue to bring moderate snow accumulations with snowfall rates at 1-2 in/hr at times with snow levels slowly lowering throughout the day.  These orographic snow showers will develop due to southwest flow, which will cause them to be a bit weaker than if the flow was from the northwest, which occurred earlier this week.

The good news is the southwest flow tends to favor Mt. Bachelor, which will see favorable conditions on Thursday and Friday. Orographic snow showers will continue into Friday with a few breaks during the day.

On Friday evening, models are showing the storm spinning off the coast moving into Oregon, which would bring another round of moderate and heavy snow. The timing of this heavier wave of precipitation should be sometime between Friday afternoon and evening. This heavy wave of snow will be brief and raise snow levels a bit, but still keep them below 2,500 feet. Scattered snow showers will continue into Saturday.

Below is a look at the National Blend of Model’s (NBM) forecasted snow accumulations from Wednesday, February 28th through Friday, March 1st.

  • Wednesday snow accumulations will mainly fall during the late afternoon and evening.

Winds on Wednesday will strengthen throughout the day as the AR approaches. Expect sustained winds around 10-30 mph with gusts to 40mph. Winds could still gust near 50 mph around Mt. Hood throughout Wednesday. As the AR moves through Wednesday night, the strongest winds will bring gusts up to 90 mph!

Winds will weaken briefly on Thursday morning but become stronger by the afternoon sustained at 20-40 mph with gusts over 50 mph. Winds will be weaker on Friday for most of Oregon, but a few areas with heavier snow showers could still see gusts over 50 mph.

Forecast on Saturday, March 2nd and Sunday, March 3rd:

Snow will continue this weekend on Saturday and Sunday. On Saturday morning, snow showers will be widespread but slowly weaken and dissipate during the afternoon and evening. On Sunday there will be another wave of moisture moving into Oregon as rounds of storms continue to spin off the coast. 

I do not have a good idea of storm intensity on Sunday but snow accumulations are coming. Most likely they will be light on both days with 3-6+ inches with total weekend snow totals approaching 6-12+ inches. 

Winds this weekend will be a lot lighter as these storms do not have ARs associated with them. This will keep skiing conditions a lot more favorable than the past week. Snow levels will also continue to stay lower than 2,000 feet, making snow ratios 10-14:1.

Extended Forecast

Active weather will continue next week starting on Monday, March 4th. The Pacific storm track and jet stream will remain active with more rounds of storms affecting the West Coast of North America with ARs associated with them. The storm track will likely be from the west, which keeps the hazard of rising snow levels low. By the latter of the week, we could finally turn dry for several days.

Below is a look at the Euro's ensemble predicted upper-level pattern from Monday, March 4th through Wednesday, March 6th.

Description: The cool, blue colors show cooler air that will be associated with the storm track. 

Thanks for reading, I will have the next update on Thursday morning between 7-8 am.
