SUMMARY

The Alaska storm, driven by the remnants of Typhoon Nuri, is set to deliver a significant cold front to the mainland United States, resulting in temperatures plummeting 20 to 40 degrees below average. The National Weather Service has issued warnings for various regions, particularly near the Columbia River Gorge, where residents should prepare for potential power outages and hazardous travel conditions. This weather pattern mirrors the behavior of hurricanes that transition into extratropical cyclones, impacting areas as far as Maine and the UK.

PREREQUISITES
  • Understanding of extratropical cyclones
  • Familiarity with the National Weather Service alerts
  • Knowledge of the Columbia River Gorge wind effects
  • Awareness of Typhoon Nuri's historical context
NEXT STEPS
  • Research the impact of extratropical cyclones on weather patterns
  • Study the historical data of Typhoon Nuri (2014) and its effects
  • Learn about the Columbia River Gorge wind phenomenon
  • Examine the National Weather Service's forecasting methods
USEFUL FOR

Weather enthusiasts, meteorologists, and residents in the Pacific Northwest preparing for severe weather conditions will benefit from this discussion.

Alaska storm brings frigid weather to swath of US
http://news.yahoo.com/alaska-storm-pushing-cold-air-toward-lower-us-090835038.html

JUNEAU, Alaska (AP) — A massive storm fueled by the remnants of Typhoon Nuri did not do much damage in Alaska's sparsely populated Aleutian Islands, but forecasters say it's anchoring a system that will push a frigid blast of air into the mainland United States and send temperatures plunging early this week.

Parts of the lower 48 states could see temperatures between 20 and 40 degrees below average, the National Weather Service said Sunday.
This is like the hurricanes that hit the US and head off NE past Maine and Nova Scotia/Newfoundland toward Ireland and the UK.

Typhoon Nuri (2014) not to be confused with Typhoon Nuri of 2008

My area is expected to have the Gorge wind effect from the pressure gradient funnel from eastern Oregon to the river valley.
AREAS NEAR THE WEST END OF THE COLUMBIA RIVER GORGE WILL LIKELY
EXPERIENCE VERY WINDY CONDITIONS TUESDAY AND WEDNESDAY. RESIDENTS
NEAR THE MOUTH OF THE COLUMBIA RIVER GORGE...PARTICULARLY IN
CORBETT...TROUTDALE AND GRESHAM SHOULD BE PREPARED FOR POWER
OUTAGES LATE TUESDAY AND WEDNESDAY. HIGH PROFILE VEHICLES WILL
ALSO NEED TO USE EXTRA CAUTION WHEN TRAVELING ALONG INTERSTATE 84
BETWEEN INTERSTATE 205 AND BONNEVILLE DAM...AND OVER THE GLEN
JACKSON BRIDGE ALONG INTERSTATE 205 DURING THIS PERIOD. IN
ADDITION...LOCATIONS AWAY FROM THE COLUMBIA RIVER GORGE ALONG THE
CASCADE FOOTHILLS MAY EXPERIENCE UNUSUALLY STRONG WINDS TUESDAY
NIGHT.

Time to batten down the hatches.
