ISON INFOGRAPHICS - 3 Possible scenarios (thanks NASA)

WILL ISON SURVIVE?

Spectacular NASA infographics on 3 possible scenarios:  

1) ISON evaporates

2) ISON emerges in smaller chunks

3) ISON survives and emerges so bright it is visible from earth

Most sungrazing comets are torn apart by the sun's intense gravity and heat, but some survive in spectacular form...check out the animations:

FLY WITH COMET ISON IN 3D- like being in a video game

Another awesome visualization compliments of NASA - worth a look at this amazing sun-grazing comet.

COMET ISON TOOLKIT-all the images, videos, mission information and more to make the most of today historic event.

TODAY scientists around the world are tracking ISON's progress today as it plunges through the sun's near atmosphere.  Stay tuned to see if it survives its perilous journey and emerges from the sun's intense gravity and heat.  this toolkit has all the images, videos, mission information and more to make the most of today's historic event.

COMET ISON - Tracking the comet's Perilous Journey Around the Sun - Will it Break Up?

Thursday, Nov. 28, 1-3:30 p.m. EST
NASA solar physicists track the comet LIVE during #ISON’s closest approach to the sun and answer your questions on Google+ during the broadcast, or via Twitter using #ISON and #askNASA.

- Don't look for ISON during the day today. NASA spacecraft will watch it and we'll post images here (the link below), including near real time images from SDO starting at 12:45 p.m. EST.  As always, never look directly at the sun.

-- If it doesn't break up, ISON will be visible near the horizon in early December. Look to the East before sunrise and to the Northwest after sunset. Watch the "What's Up?" Videofor more details.https://plus.google.com/events/c8t7i5dbr1k50oq89giloiqe8rc

Is an Arctic Blast and Snow Coming to the Northwest?

Cliff Mass Weather Blog, November 26, 2013

The media is beginning to talk about it and the emails are coming in, so perhaps it is time to talk about the potential for cold air and snow later this weekend and early next week.

My general policy is to wait until such events are about 120 hour out, because their predictability is often very low beyond that.  And although some models have been indicating a cold event for a while, their forecasts have been inconsistent--suggesting large uncertainty.  So now that we are getting close enough to see "the whites of their eyes", what do the latest model predictions indicate.

Holiday Weekend Travel

National Weather Service, Spokane, Wa
A few weak disturbances will bring a chance of light showers on Friday and Saturday. These showers are not expected to impact travel. A strong storm system will bring rain/snow, gusty winds, and colder temperatures on Sunday and Monday. Snow will likely impact the mountain passes. Snow will be possible in the valleys starting Sunday night but confidence remains low regarding amounts and location. Freezing temperatures arriving Sunday night could lead to Icy road conditions on Monday morning. Check http://www.wrh.noaa.gov/otx/ for updates.
