      WELCOME TO THE CASCADECLIMBERS.COM FORUMS   02/03/18

      We have upgraded to new forum software as of late last year, and it makes everything here so much better!  It is now much easier to do pretty much anything, including write Trip Reports, sell gear, schedule climbing related events, and more. There is a new reputation system that allows for positive contributors to be recognized,  it is possible to tag content with identifiers, drag and drop in images, and it is much easier to embed multimedia content from Youtube, Vimeo, and more.  In all, the site is much more user friendly, bug free, and feature rich!   Whether you're a new user or a grizzled cascadeclimbers.com veteran, we think you'll love the new forums. Enjoy!

Weather Links

Recommended Posts

Hey, I've been doing some searching for useful weather links around the web, and I thought that I would share what I found that I thought would be helpful, and ask if there are any others that people like to check which might supersede some of these. This is just 20 minutes of looking around, so there may be other, better ones.

 

Intellicast Jetstream Forecast

 

Western Pacific Satellite Imagery

NOAA Satellite (IR, Vis, Vapor)

 

NOAA Geostat. Sat. Server

 

PNW Snowfall Forecast

 

Western US Snow Quality Forecast

 

US Wind Forecast

 

US Wind Chill Forecast

 

PNW Precip. Forecast

 

Tomorrow Night's Cloud Cover

(would be nice to find more local forecast)

 

Park-Oriented Forecasts

 

5000' winds aloft

 

10000' Winds Aloft

 

 

Any others you use?

Maybe I should have put this in the Climber's Forum.

 

Or is it just a boring and pointless topic?

 

Or is everyone already on Holiday?

Yes, this could be in general forum. Lots of good links presented, but I like to keep it simple.

 

For weather forecasts, the NWS is best, and you can pinpoint a Fx from your regional center:

NWS Seattle

NWS Portland

NWS Spokane

 

Canada's NWS equivalent:

Environment Canada

 

Imagery loops are obviously important because the current pattern of movement can be predicted for the short-term future, complementing any forecast. Before heading out, I almost always look at two different imagery sites, one for the big picture and another that is more specific to the NW.

 

For big picture imagery, my fav is the GOES-West satellite Pacific Ocean imagery with an infrared moisture overlay originally developed at Purdue but sold to and now provided by Unisys:

Unisys GOES-West sat 12-hr enhanced infrared imagery

 

For the local precip pattern, this site is very accurate (more so than the higher-altitude Unisys imagery):

Intellicast 2-hour infrared radar loop

 

Quite often for me weather goes in hand with snow and avalanche conditions, so I check the avy forecasts in season. Other good sites for specific info and Fx models include the UW Atmospheric Sciences Dept and the Aviation Wx Center, all linked from Lowell Skoog's links list.

 

Many useful weather links here at Turns-all-year.com
