Saturday, February 19, 2011

Warmest and coldest days are based on average temperature of the entire day, starting at midnight. All other averages are based on the whole week.
  • Warmest day: 46.0ºF (Saturday)
  • Coldest day: 36.9ºF (Thursday)
  • Rainiest day: 0.81 inches (Monday)
  • Average temperature: 40.8ºF
  • High temperature: 54.1ºF (Saturday)
  • Low temperature: 31.6ºF (Friday)
  • Total rainfall: 1.93 inches
  • High humidity: 100%
  • Low humidity: 31%
  • Average humidity: 91%
  • High pressure: 29.530 inches (Sunday)
  • Low pressure: 28.851 inches (Monday) This pressure difference between Sunday and Monday gave me a headache that day.
  • Average pressure: 29.171

Weather highlights for the week
  • Lowest pressure this winter yet, at 28.851 inches on Monday.
  • Some wet snow/mixed snow and rain showers overnight from Wednesday into Thursday morning.
  • Radiate cooling caused ice/frost to form in spots and on exposed cars on Wednesday and Thursday.
  • Below freezing low temperatures on Friday morning, with ice and frost in places.

Weather for the coming week
  • Looks like more of the same, cool showery stuff, we may have a couple clear but cool or cold sunny days.
  • Monday – Wednesday could be interesting. A one-two punch weather pattern may strike. Monday a low pressure is going to slide down the Canadian west coast, and then down the Washington state coast, sucking cold arctic air down from the interior of British Columbia behind the storm. 
  • Then Tuesday into Wednesday a second low pressure wave will slide down the west coast of North America and at this point in time the air will have been cooled by the first storm enough that we could see a significant snow event. 
  • Various forecast models with several agencies are inconsistent, have been changing it seems every 6 hours and none of them agree with each other. This is leading me to believe that this will be an interesting week. 
  • Check back for any updates for winter watches or warnings.
