Here is my weekly weather quiz question for the last time. What is a “Jet Max?” Here is the correct answer. A Jet Max (or Jet Streak) is a point or area of relative maximum wind speeds within a jet stream. I’ll have a new weekly weather quiz question for you starting Monday. Please remember to post your answer as a comment by clicking on “no comments /comments” in the upper right hand portion of this page under the caption, then add your comment. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs. The answer has to be a comment to win. An email answer will not count. Good luck.

Not much relief from the drought, but with northwesterly winds at least we clear out some smoke. A couple of upper level lows (Shaded “U” shapes with blue arrows) will march out of the Gulf of Alaska at us. That will keep us in cooler temperatures for short a while. A high pressure ridge (Shaded “Arch” shape with blue arrows on previous graphic) will really heat us up Tuesday.

An upper level low (Shaded “U” shape with blue arrows) is sending moisture and smoke northward at us. We are also seeing a smoky haze over the Eugene-Springfield area caused by local area fires and the wildfires to our south. The low moves inland, finally, bringing showers and possible thunderstorms with it and that should scrub the smoke out of the air, for a while at least. A frontal system (shown moving out of Canada) will bring some cooler air with it, but we will start to warm up and dry out again over the weekend.

An upper level low pressure trough (Shaded “U” shape with blue arrows) is sending moisture and smoke northward at us. A frontal system (position shown is Friday) will be bringing more clouds and a continued chance of precipitation for the middle to the end of the workweek. The Perseid Meteor Shower peak continues tonight. It is caused by debris from the comet Swift-Tuttle. For best viewing get away from the city lights and hope for mostly clear skies after Midnight and before Sunrise.

An upper level low pressure trough (Shaded “U” shape with blue arrows) is sending moisture and smoke northward at us. A frontal system (position shown is Friday) will be bringing more clouds and a continued chance of precipitation for the middle to the end of the workweek. The Perseid Meteor Shower tonight and Thursday night. It is caused by debris from the comet Swift-Tuttle. For best viewing get away from the city lights and hope for mostly clear skies after Midnight and before Sunrise.
