Spring Climate Forecast
I did some lurking among the climate prediction models for some guesses on what spring might hold in store for us.
The main factors which usually influence the monthly climate outlook are El Nino and La Nina or neither, which is referred to as neutral conditions.
Atmospheric conditions from January through early February indicate continued neutral conditions. Neutral conditions are expected to continue through the spring of 2013.
30 day (March) climate predictions are calling for slightly below normal temperatures and average precipitation amounts for the northwest.
In other words – March is likely to be cooler but driers than the past few years.

Mountain Weather Forecast -Time: 0900
The approaching warm front is still on track to change this lovely snow to rain later today. Freezing levels are expected to reach +5000’ this afternoon or evening. Rain likely through the night.
Long-range: The precipitation will lift north tomorrow producing dry conditions tomorrow night and most of Saturday. A cold front arrives late Saturday night producing falling freezing levels and snow. There should be some nice fresh snow on the ground by Sunday morning. Next week will start out dry under building high pressure.
24hr Accumulative Precipitation Totals Starting at Noon Today:
Water by 4am = .75 – 1” Snow equivalent = 2-6”
Total inches of water by noon tomorrow = +1”
Total inches of snow by noon tomorrow = 5
Trend and Timing:
Snow will change to rain after 2pm today. It may be possible to squeeze up to 8 inches of snow before it switches to rain this afternoon. Moderate to heavy rain is expected tonight. Storm totals have downgrades a bit to +- 1” by noon tomorrow.
24hr Base Area Temperatures (F) Starting at Noon Today:
Low: 30 High: 38
Freezing level: 4000’ 6000’
Trend and Timing:
Temperatures will rise to the mid to upper 30’s this afternoon. Freezing levels could top out around 6000’ late tonight. Temperatures will remain above freezing through tomorrow.

Get out and ride today if possible, because the conditions will drastically change tomorrow. A warm front will move up from the southwest tomorrow morning. This will generate rising freezing levels and eventually rain to all elevations of the resort by the end of the day.
Long-range: Avalanche conditions will become extreme with a significant rain on snow event possible tomorrow night and into Friday. The moisture will lift north of Stevens Pass on Friday for a relatively dry evening. There is much uncertainty about what this storm will leave in its wake for the weekend; so I will leave that for tomorrow or Friday’s forecast.

The Future?
The high pressure developing off of the coast on Friday is expected to shift east over the weekend and strengthen. This has the potential to develop into and Omega Block. (Below). Block is the key word here – blocking or directing the jet stream and thus the storm track well north of the PNW. Therefore, the 6-10 day Climate forecast is predicting below normal precipitation for most of the west coast. Winter will also begin to lose its grip as the February sun climbs higher and the seasonal patterns begin to unfold.
