I am concerned with the continual 7:30 start times we may get to where we stop looking at this BLOG. Issues can arrise and catch us off guard.
New Procautionary Levels.
7:30am Start Time This means a Forecast of 2-4" the storm systems have the Minor Flu, Not SICK---Normal Caution is advised.
6:15am Start Time This means a Forecast of 6" or more the storm system has the H1N1---Elevated Procautionary Levels advised. This means the storm is SICK.
So SICK or not SICK?

Short Term: This benign weather patter will continue through tomorrow. A weak system will move through tomorrow bringing some light snow. If you have been following the California weather - the Seirra's just had a nice 60+inch storm cycle.
Long Term: The change - a large low-pressure system is tracking north toward the PNW and is expected to arrive sometime Sunday night or early Monday morning. This is coming from the SW so the game is back on for freezing levels being close to pass level. So far, it is looking like snow with the help of our east flow friend.

Fun to have new snow. Good results on the ridge today, pretty much what didn't natural during yesterdays storm, moved today. I expected less due to the lowering temperatures, I thought we would have a total lock down. Nice to do control and watch a beautiful sunrise as well.
Sounds like more snow is on the way...

Meriwether what seems to be the problem, you seem troubled, do you want to talk about it? Well Jon there is plenty of active weather out there. The challenge--with a big sigh-- is to get them to reach the North Central Cascades with cool temperatures--tears in his eyes-- Jon- I know-I know! I understand the challenge you face-- as I hand him a tissue to dry the eyes-- But thanks- thankyou so much Meriwether for bringing the snow-- Just, just how do you do it?

SPOT WEATHER FORECAST
1/13/2010 Weather
Short term: A low pressure system will brush the NW corner of the state tonight. This will provide the chance for some moderate snow showers to develop early tomorrow morning. Might just get a nice day of skiing tomorrow.
Long-term: There is plenty of active weather out there. The challenge is to get them to reach the North Central Mountains with cool temperatures. It will be possible to get some nice snow in the next few days. The weekend is looking warm and wet again.

Precipitation: light snow showers will continue today. A short burst of moderate snow will be possible tonight as the westerly flow kicks in. This could allow convergence conditions to develop. If this materializes, it could bump precipitation totals up a few inches. Snow will quickly taper off by the start of operations tomorrow. Another band of moisture is expected to move through tomorrow afternoon.
Freezing levels: Freezing levels will drop to 3000’ overnight. Freezing levels will then slowly rise to 4000’ tomorrow night.
Winds: Light east flow will give way to a push of westerlies tonight. It will be possible to get gust of +20mph during the early morning hours. Gusty winds will continue tomorrow. JDM

Patrol weather question of the day.
What is a closed low?
When you read that a "low pressure system" is... It is referring to a closed low. A closed low is a region of low pressure distinguished by a center of counterclockwise circulation (in the Northern Hemisphere), and is surrounded by one or more isobars or height contours. Closed lows aloft (i.e., above the surface) may become disconnected from the primary westerly flow and thus progress eastward more slowly. It is important to note that a cutoff low is a closed low, but it gets cut off from the main low pressure system. This is a frequent occurance with PNW winter weather patterns.

Patrol Weather Question of the day.
What is a Rex Block?
The Rex Block is a blocking pattern that in relation to the United States occurs most often in early fall and spring and most often occurs along the West Coast. A Rex Block has two adjacent highs and lows. The most impressive Rex Blocks will have a strong low pressure next to a strong high pressure. The high pressure will be located in a generally north direction from the low pressure. The low associated with the Rex Block is not completely cut-off from the upper level flow, but does have little east-west movement. Strong ridging north of the low causes the airflow to move from high latitudes to low latitudes with little comparable west-east movement of the air. The airflow pattern follows a backward "S" trajectory. Air flows into the West Coast of Canada then flows south into the Pacific off the Mexican West Coast. The Rex Block is a stuborn pattern because of its North South orientation. Once the flow leaves the Rex Block, it can finally make some significant progress to the east.

Patrol Weather question of the day.
What influences does El Nino have on the weather pattern of the PNW?
During El Nino years, the storm track more frequently splits into two preferred branches. The Aleutian Low, in the Gulf of Alaska, is deeper than usual, and one branch of the jet stream departing from its vicinity heads toward the Queen Charlotte Islands and the southern coast of the main part of Alaska, bringing mildly increased storminess to those areas. A second branch of the jet stream is seen across the southern tier of the U.S. and northern Mexico, and with higher speeds than usual. Storms approaching the Pacific Northwest, and southwest Canada, are often split and weakened as they approach the shore, as their energy is shunted toward the north and/or the south.
The Pacific Northwest, El Nino tends to bring drier winters. The area affected in this manner includes Washington, Oregon, and the more mountainous portions of Idaho, western Montana and northwest Wyoming. This area of influence extends well up into Canada, and coincides very well with the Columbia River Basin on both sides of the U.S./Canada border.
La Nina: La Nina generally brings cold, snowy, wet, active winters to the northern Cascades and the northern Rockies. There are a few exceptions to this picture among La Nina years. There appear, however, to be more such exceptions in El Nino years, to the dry, mild winter pattern these regions typically experience with El Nino.

Intersting snow pack this morning- funky in places and a bit spooky where it has been wind loaded on top of the freezing rain crust. The weather models are having a difficult time with the mixing of the warm air to the west and the cool air trapped in the east. Which means major variability in its effect on the snowpack. Be careful out there.
1/2/2010 Weather
Short term: Some upper level ridging will bring a brief end to the precipitation tonight. Another system will arrive tomorrow afternoon.
Long-term: We will once again battle the freezing levels with moderate to heavy precipitation tomorrow night and Monday. A general warmer regime with weak systems moving through will be the pattern for most of next week.
24 hour Forecast Starting at NOON on Saturday
Precipitation
“ Water: .25
“ of Snow: 2-4
Temperatures (F):
4000’ Low: 28 High: 30
5000’ Low: 26 High: 28
Winds speed/Direction
Pass level: 5-15 W
Ridge top: 5-15 W – gusty at times
TRENDS AND TIMING
Precipitation: Snow will taper to showers tonight with a relatively dry night to follow. Snow will redevelop tomorrow afternoon and become moderate to heavy into Monday morning.
Freezing levels: Freezing levels will hover near 4000’ for the rest of the day. They will then inch down to 3000’ overnight. East flow will help hold surface temperatures just below freezing tomorrow.
Winds: Breezy westerlies will continue today, but they shouldn’t be much of a nuisance. East flow will develop tomorrow. JDM

SPOT WEATHER FORECAST
1/1/2010 Weather
Short term: A low pressure system spinning just off the NW coast will drive waves of moderate to heavy precipitation into the PNW today. There still is a chance of warmer air invading, so the potential of some rain in the base are is still there. Moderate to heavy precipitation will continue today and tomorrow.
Long-term: Active weather will continue through the weekend. Long-range models start to disagree on what next week will look like. For now, another system will move up from the south on Monday. This has the potential to bring more warm air to the PNW.
24 hour Forecast Starting at NOON on Friday
Precipitation
“ Water: .75+
“ of Snow: 6-10
Temperatures (F):
4000’ Low: 24 High: 34
5000’ Low: 22 High: 30
Winds speed/Direction
Pass level: 10-15 WSW
Ridge top: 10 -20+ W gust to 40 possible.
TRENDS AND TIMING
Precipitation: Waves of moderate to heavy snow will continue today. Models are still indicating the potential for some rain/snow mix around 4000’ later today. A Puget Sound Convergence will be possible tonight. This could bump up snow totals.
Freezing levels: Freezing levels will be between 4000’-4500’ today and then fall to 3000’ tomorrow. There is a chance of a spike in freezing levels this afternoon as warm air tries to move in from the SW. Current east flow will help keep surface temps low until the shift in winds. Good old east flow. .
Winds: Winds are expected to shift from SE to SW and then W by this evening. High wind warning are currently posted on the coast. Look for strong Westerly winds to blow tonight - could get 40 mph gust. Winds should quickly taper off tomorrow morning as things start to calm down. JDM.
