An upper level low (shaded area) is moving down from the the North and will bring cold Arctic air in behind it. A new cold front has moved in from Canada and has brought the cold air down from the North. This front will produce very little precipitation which could fall in the form of snow flurries. A colder blast of Arctic air will follow Sunday, maybe snow flurries, but again no accumulation expected, so far anyway. The colder weather will last into the beginning of next week.

An upper level low (shaded area) is moving down from the Gulf of Alaska and will bring cold Arctic air in behind it.. A new cold front will move in from the Gulf of Alaska and push the cold air down from the North (see last frame of cold front movie series). This front will be weak and produce very little precipitation which could fall in the form of snow flurries. A cold blast of Arctic air will follow Sunday, maybe snow flurries. The next threat of a wintery mix, though slight for the valleys, will move in late Wednesday night and early Thursday morning.

For those of you living in the Eugene-Springfield area the following event could be just what Santa ordered.

Breakfast with Santa and Mrs. Claus planned

The Eugene Downtown Lions Club’s second annual “Breakfast with Santa and Mrs. Claus” is being held Saturday December 12th from 8:30 AM until 12:00 PM at St. Thomas Episcopal Fellowship Hall, 1465 Coburg, Road, Eugene.

The profits from the breakfast will go to help your neighbors who really need it.

A high pressure ridge that is over the Pacific Northwest will continue protecting us until late Friday. That’s when a new cold front will move in from the Gulf of Alaska. This front will be weak and produce very little precipitation which could fall in the form of snow flurries. The bigger threat of a wintery mix will move in by Wednesday.

For the Willamette Valley: Skies will be mostly cloudy with fog and freezing fog overnight low 23. Friday morning will start off with more  fog and freezing fog (watch out for slippery roads) then a mix of clouds & sun in the afternoon (if we are lucky) high near 44-47. Mostly cloudy & not as cold Friday night low 24-27. A mix of clouds and sun  Saturday and cooler high 42-44. Partly cloudy at night low 24.

Wednesday and Wednesday night will be mostly cloudy with a (60%) chance of rain high 43 low 34. Rain will be likely (60%) Thursday high 44.

For the Umpqua Basin the daytime highs will be a bit cooler than the Willamette Valley through Sunday then even Monday and a touch warmer Tuesday through Thursday. Overnight low temperatures will be about 5 degrees warmer than the Willamette Valley through Saturday night and about the same as the Willamette Valley through Thursday.

At the Coast high temperatures  and lows will range from 3-5 degrees warmer that the Willamette Valley.

For the Cascades:  The free air freezing level will be at 6,000′ tonight, up to 7,000′ late at night the 5,000′  Friday. The snow level will fall to well below the passes and stay there Saturday through Thursday. The best chance for snow accumulation will be Wednesday night and Thursday.

Here’s a your Civil War Football game forecast. At kickoff time 6:00 PM the temperature should be in the upper 30s and winds N 5-10 mph and diminishing late at night. The sky condition is the most difficult part. There should be clear skies at kickoff with increasing low clouds or fog as the game progresses. It’s possible the low ceiling weather could begin over Autzen Stadium when the game begins. Bundle up because the temperature will be falling through the 30s before the game is over.

A high pressure ridge that is over the Pacific Northwest will continue protecting us for the next couple of days. The next cold front to bring back precipitation will be here late on Friday. For now look for dry weather with late night and early morning fog.

For the Willamette Valley: Today will start out with morning fog/freezing fog and clouds, then become mostly sunny high 44-47. Mostly cloudy tonight with patchy fog and freezing fog  again low near 24-26 . That means a chilly but dry evening for the Civil War  football game at Autzen Stadium. The temperature at kickoff time 6:00 PM will be in the upper 30s so bundle up if you are going to the game.  It should be down to the upper 20s by  the time you are on your way home from the game. Mostly cloudy Friday morning with more patchy fog then a mix of clouds & sun in the afternoon high near 44-47. Mostly cloudy & cold Friday night and early Saturday morning with a slight chance of showers or snow flurries (no accumulation) low 27-30. Partly cloudy Saturday through Tuesday with a slight chance of showers highs near 40 lows near 30. The snow level will drop down to about 1,000′ Monday night, but again no snow accumulation is expected as this system should be quite dry. Tuesday will be partly cloudy with a slight chance of showers high near 40. Tuesday night through Wednesday it will be mostly cloudy with a chance of showers 30% Tuesday night and 50% by Wednesday. For the Umpqua Basin the daytime and overnight temperatures will be just a few degrees warmer than the Willamette Valley.  At the coast high temperatures will be in the mid 40s to the low 50s and lows from above freezing at night.

For the Cascades:  The free air freezing level will be down to 8,000′ today and tonight, dropping to 5,500′ Friday. The snow level will fall to well below the passes and stay there Saturday through Wednesday (2,500′ Tuesday night & Wednesday) with a slight (20%) chance of snow showers.

Mostly cloudy Thursday night with patchy fog again low near 24-26 . That means a chilly but dry evening for the Civil War  football game at Autzen Stadium. The temperature at kickoff time 6:00 PM will be in the upper 30s so bundle up if you are going to the game.  Mostly cloudy Friday morning with more patchy fog then a mix of clouds & sun in the afternoon high near 44-47. Mostly cloudy & cold Friday night with a slight chance of showers or snow flurries (no accumulation) low 27-30. Partly cloudy Saturday through Tuesday with a slight chance of showers highs near 40 lows near 30. The snow level will drop down to about 1,000′ Monday night, but again no snow accumulation is expected as this system should be quite dry. Tuesday will be partly cloudy with a slight chance of showers high near 40. Tuesday night through Wednesday it will be mostly cloudy with a chance of showers 30% Tuesday night and 50% by Wednesday. For the Umpqua Basin the daytime and overnight temperatures will be just a few degrees warmer than the Willamette Valley.  At the coast high temperatures will be in the mid 40s to the low 50s and lows from above freezing at night.

For the Cascades:  The free air freezing level will be at 9,000′ tonight, down to 8,000′ Thursday and Thursday night, dropping to 5,500′ Friday. The snow level will fall to well below the passes and stay there Saturday through Wednesday (2,500′ Tuesday night & Wednesday) with a slight (20%) chance of snow showers.

Here’s a quick look at the forecast for the Civil War Football game Thursday. At kickoff time 6:00PM the temperature should be near 40 and winds NE 5-10 mph. The sky condition is the most difficult part. There should be partly cloudy skies at kickoff with increasing clouds and fog as the game progresses. It’s possible the low ceiling weather could already be over Autzen Stadium when the game begins. Bundle up because the temperature will be falling through the 30s before the game is over.

A high pressure ridge that is slowly pushing into the Pacific Northwest will continue protecting us for the next couple of days. The next cold front to bring back the chance of rain will be here on Friday. For now look for dry weather with late night and early morning fog.

For the Willamette Valley : The skies cleared up as far south as Salem Tuesday, but not so with the rest of the southern Willamette Valley. That’s why the temperatures stayed so cool. Just a little bit of sunshine could have warmed us up into the mid and upper 40s which is what I predicted. Today and Thursday look for a mix of clouds and sun after morning fog and clouds (as long as they clear out) high 44-47. Partly cloudy Thursday evening then mostly cloudy with patchy fog at night low near 3o tonight and Thursday night. That means a chilly but dry evening for the Civil War  football game at Autzen Stadium. Mostly cloudy Friday morning then a mix of clouds & sun in the afternoon with a slight chance of rain and partly cloudy at night still a slight chance of rain high near 44-47 low 33-36. Partly cloudy Saturday through Tuesday with a slight chance of showers highs 40-45 through Sunday cooling to near 40 Monday (warming a bit Tuesday) lows near 30 at night Saturday through Tuesday. For the Umpqua Basin the daytime and overnight temperatures will be about the same as the Willamette Valley.  At the coast high temperatures will be in the mid 50s through Friday then back the upper 40s and lows from 35-40 at night.

For the Cascades:  The free air freezing level will be at 7,000′ today and  tonight, up to 8,000′  Thursday,  7,000′ at night. The snow level will fall to 4,000′ Friday, 3,000′ Friday night, 2,500′ Saturday, and 3,000′ Saturday night. Sunday through Tuesday the snow level will remain at about 2,500′ with a slight (20%) chance of snow showers.
Congratulations! We have a winner in this week’s weather quiz. Here is the question again. What was the deadliest hurricane to strike the United States and  when did it occur? The winner, Matt, posted his response on the November 30th  edition of my forecast. The answer he gave is the Galveston, Texas hurricane in September of 1900 which killed at least 6,000 people and possibly as many as 8,000 to 12,000′ people. Not a single building on Galveston Island escaped damage and more than half were swept into the sea. This storm single-handedly made September the deadliest month on the calendar for hurricane-related deaths in the United States. You will also notice that the storm had no name. The practice of giving storms people’s names was introduced by Clement Lindley Wragge, an Anglo-Australian meteorologist at the end of the 19th century. He used female names, the names of politicians who had offended him, and names from history and mythology. Now the choice of names comes through the World Meteorological Organization.

A high pressure ridge just offshore will continue protecting us, far a while at least. The next storm system to bring back the chance of rain will be here on Friday. For now look for dry weather with late night and early morning fog.

For the Willamette Valley : Today after AM fog/freezing fog.frost look for a mix of clouds and sun with some lingering afternoon fog high 48, then mostly cloudy at night with patchy fog low 34. A  mix of clouds and sun  Wednesday and Thursday after morning fog and clouds high 47-50. Partly cloudy Thursday evening then mostly cloudy with patchy fog at night low 35. That means a chilly but dry evening for the Civil War  football game at Autzen Stadium. Mostly cloudy Friday morning then a mix of clouds & sun in the afternoon with a slight chance of rain and partly cloudy at night still a slight chance of rain high near 50 low 36. Partly cloudy Saturday through Monday with a slight chance of rain highs 44-48 lows 33-36. For the Umpqua Basin the daytime temperatures will be about the same as the Willamette Valley, but the low temperatures will be in the mid 30s.  At the coast high temperatures will be in the 50s to near 60 for the daytime highs and  the mid to upper 30s at night.

For the Cascades:  The free air freezing level will be 8,000′ today, 7,500′ tonight, rising to 9.000′ Wednesday and  Wednesday night, down to 8,000′  Thursday,  5,500′ at night. The snow level will fall to 4,000′ Friday, 3,000′ Friday night, 2,500′ Saturday, and 3,000′ Saturday night. Sunday through Monday the snow level will remain at about 2,500′. The chance of rain/snow will remain at about 20% for the period Friday through Monday.
Here again is my weather quiz question for this week. What was the deadliest hurricane to strike the United States and  when did it occur? Please place your answer as a comment  after this post. The first person to correctly answer the question will win a week of free forecasts personalized for your needs. Good luck.
