Eugene’s low Saturday of 19 was just 1 degree below the record low for the date of 18 set in 1962.
Roseburg’s low of 19 was just 3 degrees below the record low for the date of 16 set also in 1962.
North Bend’s low of 25 was just 4 degrees below the record low for the date of 21 also set in 1962.

The jet stream shows a cold trough of low pressure ( “U” shaped area) pushed down and brought winter weather  with it. A burst of cold Arctic air has dropped in behind another cold front that slid down from the North into California and that air mass will move to the Northeast away from us for a little warming. Weak high pressure has cleared us out for part of the weekend at least.  Low pressure will move back in sending more frontal systems our way (interior on Wednesday and coastal one Thursday) and bring precipitation with back for next week. Be careful driving on roadways that still have the remnants of snow or ice on them because they will be slippery until we stay above freezing.

A difficult weather quiz question goes unanswered.
________________
Sorry no winner this week.  Here again is my weekly weather quiz question. What is a fire tornado? Here is the answer in great detail since it’s probably something you have never heard of. A fire whirl, colloquially fire devil or fire tornado, is a rarely captured phenomenon in which a fire, under certain conditions (depending on air temperature and currents), acquires a vertical vorticity and forms a whirl, or a tornado-like vertically oriented rotating column of air. Fire whirls may be whirlwinds separated from the flames, either within the burn area or outside it, or a vortex of flame, itself. An extreme example is the 1923 Great Kant? earthquake in Japan which ignited a large city-sized firestorm and produced a gigantic fire whirl that killed 38,000 in fifteen minutes in the Hifukusho-Ato region of Tokyo.[1] Another example is the numerous large fire whirls (some tornadic) that developed after lightning struck an oil storage facility near San Luis Obispo, California on April 7, 1926, several of which produced significant structural damage well away from the fire, killing two. Thousands of whirlwinds were produced by the four-day-long firestorm coincident with conditions that produced severe thunderstorms, in which the larger fire whirls carried debris 5 kilometers away.
[2] Most of the largest fire tornados are spawned from wildfires. They form when a warm updraft and convergence from the wildfire are present.[3] They are usually 10-50 meters tall, a few meters wide, and last only a few minutes. However, some can be more than a kilometer tall, contain winds over 160 km/h, and persist for more than 20 minutes.[4]

I’ll have a new weekly weather quiz question for you beginning next Monday. Please post your answer as a comment by clicking on “no 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.

The jet stream shows a cold trough of low pressure ( “U” shaped area) pushed down and brought winter weather  with it. A burst of cold Arctic air has dropped in behind another cold front that slid down from the North. A weak high pressure has cleared us out for part of the weekend at least. Be careful driving on roadways that still have the remnants of snow or ice on them because they will be slippery. Low pressure will move back in and bring precipitation with it for next week.

The jet stream shows a cold trough of low pressure ( “U” shaped area) starting to swing down and it is already bringing winter weather ahead of and then with it. A burst of cold Arctic air is pushing in behind another cold front sliding down from the North. Be careful driving on snow covered or icy roads. The colder temperatures will turn snow left on the streets into icy spots. Remember to do everything in slow motion. No quick moves while driving under these conditions.

I live at 600 ft. on the South side of Eugene. Here’s a look at the height of the snow storm in my neighborhood.

It looked pretty, but between 1 and 2 inches of snow didn't last long.

One of my neighbor’s children enjoyed sledding.

This is what a "snow day" is all about.
