Here is my weekly weather quiz question for the last time. What is a “Derecho?” Here is the correct answer. A Derecho (Pronounced day-RAY-cho) is a widespread and usually fast-moving windstorm associated with convection. Derechos include any family of downburst clusters produced by an extratropical MCS (Mesoscale Convective System), and can produce damaging straight-line winds over areas hundreds of miles long and more than 100 miles across. I’ll have a new weekly weather quiz question for you starting Monday. The first person to post the correct answer as a comment on this page will win a week of free personalized weather forecasts tailored to your needs. Good luck.

Another Upper Level Low Pressure Trough (Shaded “U” shape with arrows) continues to control our weather with temperatures well below normal, but the temperatures are slowly warming and the snow seems to be staying in the mountains. The graphics for days 1-3 show the low pressure disturbance moving along the Pacific Coast. The graphics for days 3-7 show what looks to be a strong storm system headed toward the Pacific Northwest by next Thursday through Saturday.
Note: It looks like Willamette Pass Ski, due to a lack of snow, is still not operating, but Hoodoo is open Wednesday through Saturday from 9 AM- 9 PM. Mt. Ashland is open and report all lifts are operating. They will also be open 9 AM until 4 pm March 24th through April 1st for Spring break. Check their websites for details on days of operation and ski conditions.
Note: Daylight Saving Time begins at 2 AM Sunday March 11th. That’s not this weekend, but the one after that.
