Winter Season Part 3

Summary

Afternoon rain showers may pop up on Friday. The low approaches on Friday with gusty winds and a drop in temperatures. Snow accumulations will likely occur over the weekend. It will be a wintery weekend for the umpteenth time this year as winter doesn't want to let go. Next week Spring might only be around in a limited form with colder temps and breezy conditions.

Short Term Forecast

Thursday Afternoon Pop-Up Showers 

We have a chance for some afternoon rain showers today, Thursday. Temps will be near 50 degrees for the high at Main Lodge so the son level will be over 10K FT if not a bit higher. Precip accumulations look minimal at best. Winds look calm today. Enjoy today, since it will be the last true Spring day for a while. We go back to a much colder and showery pattern with plenty of wind in the next few days. 

Cut-Off Low Approaches Friday & Snow Showers Begin Saturday 

We've talked about this cut-off all week and it's going to create a real change in our weather starting tomorrow, Friday. The biggest change will be the colder temps and stronger winds. Winds over the summit look to get gusty on Friday. Up to 60 MPH out of the South-Southwest on both Friday & Saturday so the upper mtn. is likely to get affected by the strong winds. 

Temps will drop significantly. We'll see base temps down into the low 40's on Friday and then low 30's on Saturday. The snow level will drop from over 9K FT Friday morning to 6,500 FT by Saturday morning. It will likely continue dropping into the 4K FT range Saturday night. 

I don't expect much accumulation on Friday. Saturday is the day we should see more snowfall. The models are struggling to pin down an exact snowfall solution but overall the forecast hasn't changed much. 

Sunday Snowfall Continues 

The snow showers look to continue on Sunday. The spinning low will rotate in 2 distinct waves of moisture. One should come through on Saturday and another on Sunday. Temps should be similar on Sunday with snow levels in the 5K FT range. Winds should calm as well with only 15 - 25 MPH gusts out of the West-Southwest over the summit. 

The GFS is not as bullish as the Euro or WPC model and the average is right around 0.50 inches of liquid. With the higher snow levels and low snow-to-water ratios, we'll see 8:1 snow ratios at first and maybe 11:1 during the coldest part of the storm. 

My forecast is still for 2 - 4 inches of snowfall by Sunday night at Main Lodge. Up to 6 is possible on the summit. 

I'll update you tomorrow on this forecast one more time since I will be traveling for work on Saturday and Sunday. Actually, I'm leaving tomorrow morning, but I'll get one more post out. 

Extended Forecast

The forecast for next week has taken an interesting turn over the last couple of days. Instead of us seeing Spring conditions return we might just see a continuation of winter-like days with breezy winds and a few snow shower chances. 

Temps will warm back into the low to mid 40's at the bases by Monday and Tuesday but they could come right back down on Wednesday and stay cooler for the rest of the week. That doesn't necessarily mean much in the way of accumulations but if snow shower chances are present it will keep us cooler and keep the snow from melting as fast during this month. 

I'll keep you posted. Winter is clearly not quite done with us yet. 

Till the next one... Mike out.
