1. Seattle, WA January 31, 2011

2. Where is Seattle?

4. Lots of terrain and orography

5. Satellite http://www.atmos.washington.edu/~ovens/lo ops/ Some high clouds in the area, but they are to the north. There appears to be a ridge in the area for now.

6. Radar http://www.weatheroffice.gc.ca/radar/index_e.ht ml?id=XSIhttp://www.weatheroffice.gc.ca/radar/index_e.ht ml?id=XSI http://www.rap.ucar.edu/weather/radar/displayR ad.php?icao=KATX&prod=bref1&bkgr=black&en dDate=20110131&endTime=-1&duration=0http://www.rap.ucar.edu/weather/radar/displayR ad.php?icao=KATX&prod=bref1&bkgr=black&en dDate=20110131&endTime=-1&duration=0 Not much on radar except for areas of heavy precip? Or is that something else? Hmm…

9. Long wave ridge pattern Strong High pressure to the south –Stable –Subsidence Temperature gradient near the coast

10. MOS http://www.nws.noaa.gov/cgi- bin/mos/getall.pl?sta=KSEA The MOS values are pretty similar to each other, so there is good agreement between models.

11. High 44 –North winds will be light –Clouds look to be lingering Low 31 –Clouds hanging around overnight –Light winds so more cooling

12. Winds 7 –Winds might pick up if there is some clearing Precip 0 –Longwave ridge patter –High pressure
