11/18/2010 Weather
24hr SNAP SHOT starting at NOON today
Water - .25, Snow 2-4
Freezing levels - 2000' steady
Wind - 0-10 W
General Discussion: My unofficial base area new snow measurement came up with 12”. We should have a 13-16” base out there - a good start. A complex stacked low pressure system will continue to spin bands of moisture through the PNW today.
Long-term: Bands of snow showers will slowly taper off during the next few days. The start of next week looks dry with no significant systems in the picture. Cold air streaming in from the interior north with keep surface temps well below seasonal norms this weekend. Keep an eye on those pipes this weekend.
TRENDS AND TIMING
Precipitation: Moderate snow showers will continue today and then slowly taper off through the weekend. It will be possible to pick up another 4-8” inches by Saturday morning.
Freezing levels: Freezing levels will remain low, around 2000’ for the next 24-36 hours. Cold air from the northern interior will push temps low this weekend.
Winds: Westerly flow will weaken today and then swing south then East during the next 24 hours. Off shore/East flow will be well established by Saturday. jdm
