24HR FORECAST starting at NOON today
Water - .25 Snow - 2-4
Freezing levels - 1000'
Winds 0-10 WSW
General Discussion: The low pressure cell, just off the southern Canadian coast, responsible for all this great snow, will begin to weaken today. Another system is driving up from the SW which will bring more precipitation and warmer temperatures to the mountains.
Long-term: This active weather pattern is expected to continue through the week. “In like a lion…”
TRENDS AND TIMING
Precipitation: The snow is expected to lighten up today but continue. Snow will intensify tomorrow afternoon as the next system arrives.
Freezing levels: Freezing levels will begin to rise tomorrow afternoon and could briefly reach 4000’ early Wednesday morning.
Winds: Winds will also begin to mellow today. The wind is expected to shift SW then E over the next 24 hrs.

Precipitation: Snow will develop today and fall through the following 36hrs. The bulk of the snow will come after 2am and then ramp up tomorrow with the aid of a developing convergence zone. 72hr storm totals are currently exceeding 2” of water or +20” of snow. I think that might be a bit high, but we will go with for now.
Freezing levels: Freezing levels will remain well below pass level through the week.
Winds: Winds will be steady out the west through Wednesday. Expect gusty ridge top winds to exceed 25mph tonight and early tomorrow morning. No significant winds (40+) are expected.

A low pressure system will slide down the coast tonight, but it will remain off shore, so little to no moisture is expected to reach the mountians.
The next system of interest will ride good NW flow into the PNW starting tomorrow evening. Nice snow potential for Tuesday/Wed - Stay tuned for details on that tomorrow.

Long-term: Active weather will continue into the coming week.

General Discussion: An active weather pattern will begin tonight as a series of fronts get set to move into the PNW. Freezing levels will again be near pass level – so mixed rain and snow will be possible at times.
Long-term: Cool NW flow is expected enter the scene late Saturday night which should allow for good snow in the mountains for Sunday. The long range outlook continues to show an active winter weather pattern through next week.
TRENDS AND TIMING
Precipitation: A wave of moisture, preceding the main frontal system, will enter the mountains late tonight or early tomorrow morning. There will be a break during the day tomorrow before the main front arrives later in the day. Mixed rain and snow will eventually turn to snow through the weekend.
Freezing levels: We will have warm surface temperatures and high freezing levels today. Freezing levels will once again be on the cusp as they bounce between 4000’ and 5000’ through the weekend. Freezing levels are expected to fall as cooler air enters the scene on Sunday. At this point, Sunday looks like the best chance of significant snow.
Winds: Winds won’t be much of a factor until tomorrow afternoon’s front pushes through. I will wait until tomorrows model run to get a better handle on the wind potential for tomorrow night.

Word of the week - CYCLOGENESIS
I thought it interesting that the National Weather Service used this term in the their discussion.
cyclogenesis is just the the intensification or development of a cyclone.
A cyclone is a large-scale, atmospheric wind-and-pressure system characterized by low pressure at its center and by circular wind motion, counterclockwise in the Northern Hemisphere - or in other words a low pressure system.

General Discussion: A warm front will move over the crest today bringing a rise in temperature. A strong cold front will quickly follow, enhancing the moisture, lowing temperatures and also producing high winds.
Long-term: The snow will begin to taper off after noon tomorrow as high pressure begins to build. Dry and clear conditions with seasonally normal temperatures will be on the menu for the remainder of the week.
TRENDS AND TIMING
Precipitation: A spike in temperature this morning will bring a period of mixed rain and snow below 4500’. Strong westerly flow with potential convergence conditions will bring heavy precipitation to the mountains tonight. Snow will begin to taper off after noon tomorrow.
Freezing levels: Freezing levels will bounce between 4000’ and 5000’ for the next 6-12hrs. The trend over all will be cooling – freezing levels will be well below pass level by noon tomorrow.

STEVENS PASS MOUNTAIN WEATHER
2/3/2011 Weather
24HR SNAP SHOT starting at NOON today
Water - .5-.75 Snow - 1-3
Freezing Levels - rising to +6500'
Winds 10-20 gust to 40mph
General Discussion: The high pressure that we have enjoyed for the last few days is weakening and drifting south. This will open the door for a series of fronts to make their way through the mountains. A vigorous warm front will move through today bringing snow then rain. Watch out for a freezing rain event east of the crest.
Long-term: A cold front will follow tomorrow dropping freezing levels and thus producing snow over the weekend.
TRENDS AND TIMING
Precipitation: An interesting mix of snow and rain, influenced by inverted temperatures will begin today. The rain will likely freeze to the cold surfaces (freezing rain) before the surface warms up. Convergence flow could enhance orographics which will likely increase precipitation amounts. Rain will change to showers tomorrow afternoon.
Freezing levels: Freezing levels will rise to 6500’ or higher by 7pm tonight. Freezing levels will remain above pass level through the night. Freezing levels will then fall tomorrow as the cold front approaches.
Winds: Strong westerly flow will accompany the front today. Sustain 40mph winds with higher gust will be possible.
