COLD: Below zero F today at almost all NWAC sites! was created by Amar Andalkar

Quite an unusual weather event temperature-wise occurred overnight and this morning: almost every single NWAC telemetry site recorded a minimum below 0 °F! Don't recall the last time that might have happened.

Overall, 22 out of 25 operating NWAC sites recorded minimums below 0 °F overnight (on at least one of the temperature sensors for sites with multiple temperature sensors), with 2 other sites reaching 1 °F. At most of the sites, the minimum occurred right around sunrise, normally the coldest time of day (all other factors being equal). But at a few higher-elevation sites (Washington Pass 6680', Crystal Mountain 6830', Camp Muir 10110', Timberline 7000'), the minimum occurred near midnight, as the coldest air masses were apparently moving through around that time and the air then warmed by several degrees prior to dawn.

The current forecast predicts that temperatures tonight and tomorrow morning might even be a few degrees colder than today's at many of these sites, except at the higher-elevation sites where the air should be warming late tonight and into tomorrow.

(Note about the "-0" readings: apparently, the temperature sensors at most (all?) of these sites read in 0.1 °F increments, but are rounded to 1 °F increments for display online. Hence "-0" implies a temperature between -0.1 and -0.4 °F.)

It was so cold I didn't realize I was sweating today until I took my hat off and my hair instantly froze. I think the current conditions in the Cascades rival some of the coldest weather I've played outdoors in (okay, I do recall a day skiing as a kid back east where the dry bulb was -13F and the wind chill below -30F. $%#@ing resort was making snow, too...)

Thanks for the telemetry round up, Amar

Well, the overnight and early morning hours of Saturday, December 7, shown in the data above will remain the coldest period throughout the WA Cascades and Olympics in the last several (perhaps many) years. Somewhat surprisingly, despite forecasts predicting the coldest night of the year at most locations in western WA, the temperatures early on Sunday, December 8, were warmer at almost every single NWAC site, generally by about 5 to 15 °F. The only exceptions which were colder by a few degrees were Mazama 2170', Blewett Pass 4100', and Government Camp 3660'. Only 10 out of 25 operating sites recorded minimums below 0 °F early on December 8, versus the night before when 22 of 25 sites went below 0 °F with 2 other sites reaching 1 °F.

The really cold weather overnight into Sunday, December 8, was farther south, where temperatures dropped below -20 °F throughout most of eastern Oregon, northeastern California, and northern Nevada. Here is a plot of 24-hour minimum temperatures from Mesowest (which collects telemetry from many different networks of sites including RAWS, SNOTEL, AgriMet, DOT, airports, railroads, etc.), go to www.wrh.noaa.gov/mesowest/gmap.php?map=mfr, select "24 hr Max/Min", "24Hr Min Temp", and set the Temps data filter to hide warmer temps:

The jackpot was just east of the Cascade Range along the US 97 corridor from Klamath Falls north to Bend, where dozens of sites recorded minimums below -30 °F, capped by -39 °F at the Christmas Valley AgriMet site and -41 °F at the ODOT Horse Ridge site on US 20.

This region consists of broad plains within shallow basins at elevations of 4200-4800 ft, entirely blanketed by several meters of pumice (the Mazama Ash from the climactic eruption which formed Crater Lake about 7700 years ago). The extreme cold overnight was due to a combination of high elevation, partially to completely closed basins where cold air could sink and pool, and several inches of new snowfall Friday-Saturday followed by complete clearing Saturday night to provide very strong radiational cooling.

Minimum temperatures were generally much warmer at higher elevations closer to the volcanoes of the Cascade Crest, although still well below 0 °F at most sites. But one exceptional high-elevation site on the largest of the Cascade volcanoes also dropped below -30 °F: the Medicine Lake CCSS site , located just NW of the lake which fills part of the caldera atop the huge shield of Medicine Lake Volcano . This site is also ideally situated for extreme cold, located at high elevation on a flat pumice plain within a completely closed basin surrounded on all sides by the caldera rim which extends roughly 500-1000 ft above the elevation of the lake, with about 1 ft of new snowfall Friday-Saturday to enhance the radiational cooling.

Perhaps even more surprising than the extremely low overnight temperature is how quickly temps are warming this morning under bright sunshine, which looking through older data appears to be a typical pattern after very cold clear nights at this site. The temperature today has risen from -31 °F to +31 °F in only 5 hours! The pool of extremely cold air filling the lowest part of the lake basin was probably very shallow, perhaps only a few dozen feet thick, to allow such rapid warming.

Those temperatures in eastern Oregon (as low as -41F) look like they could be very close to all-time record low temperatures for the state. It also looks (although a long way out) that we could get another Arctic front around the 20th of December….

Those temperatures in eastern Oregon (as low as -41F) look like they could be very close to all-time record low temperatures for the state.

(a belated reply which I started writing back then in December, but never completed and posted)

Most of the December 8 low temperatures in that region (east of the Cascade Range along the US 97 corridor from MacDoel, CA, through Klamath Falls north to Bend) were all-time record lows at those sites, including the -41 °F at the ODOT Horse Ridge site, the -39 °F at the Christmas Valley AgriMet site, and the -31 °F at the Medicine Lake CCSS site , in the caldera of Medicine Lake Volcano -- although records for the first two sites extend back only 10 and 15 years, with almost 30 years at Medicine Lake. The city of Lakeview (one of the highest in Oregon at 4800 ft) on the eastern edge of this region also set an all-time record low of -27 °F.

However, the all-time record low temperatures for the state of Oregon are much colder than any of those: several sites have reached -50 °F or colder, all located farther east in eastern Oregon, all in valleys surrounded by mountain ranges where cold air can sink and pool. Topped by the -54 °F recorded at Ukiah on February 9, 1933, and Seneca on February 10, 1933, the latter of which is the official state record.

However, the arctic blast this time was not as severe in eastern Oregon as it was in south-central Oregon, so Seneca only got down to -28 °F, far short of the values at the coldest sites. Here is data from the NCDC for Seneca during the December cold snap:

Well, it happened AGAIN! Another cold snap very similar in severity to that of December 7, 2013, which was the coldest in many years for the Washington and Oregon Cascades. Once again this morning, almost every single NWAC telemetry site recorded a minimum below 0 °F!

Overall, 24 out of 27 operating NWAC sites recorded minimums below 0 °F overnight (on at least one of the temperature sensors for sites with multiple temperature sensors), with 1 other site reaching 1 °F. At all of the sites, the minimum occurred right around sunrise or just prior, normally the coldest time of day (all other factors being equal), unlike on December 7 when a few higher-elevation sites had their minimums near midnight and then warmed by several degrees prior to dawn. Low temperatures this time were fairly comparable to those on December 7. The coldest sites were Mission Ridge 6730' at -15 °F, Camp Muir 10110' at -14°F, and Crystal Mountain Green Valley 6230' at -13 °F. The three sites that failed to go below zero were Lake Wenatchee 1930' at 1 °F, Hurricane Ridge 5250' at 3 °F, and Berne 2700' at 5 °F.

The current forecast predicts that temperatures tonight and tomorrow morning should be similar to today's at many of these sites, except at the higher-elevation sites where the air should be warming slightly late tonight and into tomorrow.

Note about the "-0" readings: apparently, the temperature sensors at most (all?) of these sites read in 0.1 °F increments, but are rounded to 1 °F increments for display online. Hence "-0" implies a temperature between -0.1 and -0.4 °F.

It wasn't too bad this morning up near Mission Ridge if you kept moving. Just a little striding and turning out in the woods. Get out of the sun and stop moving and it got cold quick.

Talk about wind chill.... Mission, 46 mph peak gusts at -15F, 88% humidity. Probably would freeze exposed skin in under 5 minutes. Frostbite in 12-15 minutes. I have been in a -33 day doing lifts with little to no wind aside from downhill motion and less than one hour was pushing it. Restaurant packed and out of hot tasty beverages by 11:00 a.m. Ski Patrol busy treating cold injuries. Gotta be hardy for days like that. Best advice I'd have is check your partners out frequently for white, frozen splotches on ears, nose (less likely), cheeks, & chin. It is Frostbite and can do damage quick.

Central Oregon and the Willamette Valley are pretty chilly again and the Corvallis-Eugene areas are currently under a winter storm warning with 4-8" in the forecast Thurs-Fri.

Fingers crossed for some lowland snow and that everyone stays safe on the roads!

What? Most years Mission Ridge wouldn't open on Thanksgiving if it weren't for snowmaking. This year Mission wouldn't be open at all if it weren't for they're extensive snowmaking.
Crystal has some limited snowmaking too, pretty sure.

too bad there aren't any snow makers in this state!

Well, the second day of this cold snap ended up colder than the first at most NWAC sites (except some higher-elevation sites), unlike the December 2013 event which had only one really cold day and then failed to meet forecasted lows the next night. Once again this morning, almost every single NWAC telemetry site recorded a minimum below 0 °F!

Overall, 25 out of 27 operating NWAC sites recorded minimums below 0 °F overnight (on at least one of the temperature sensors for sites with multiple temperature sensors), with 1 other site (Hurricane Ridge) reaching 0 °F for 5 hours and only Berne failing to reach zero with a minimum of 6 °F, while Lake Wenatchee 1930' easily joined the below-zero ranks this night reaching -5 °F. Of the two NWAC sites which are offline, Chinook Pass 5500' and 6240' easily ended up well below zero based on the nearby Cayuse Pass 5240' and Morse Lake 5410' SNOTEL sites which reached -6 and -7 °F, while Mt St Helens 3260' did not likely reach zero based on the four SNOTEL sites located on Mt St Helens, June Lake 3440', Spirit Lake 3520', Sheep Canyon 3990', and Swift Creek 4440', which bottomed out at 4 to 8 °F.

The coldest sites were Mazama 2170' at -17 °F (only -5 °F yesterday), Washington Pass 6680' and 5450' at -15 °F (only -7 °F yesterday), Mission Ridge 6730' at -15 °F (same as yesterday), and Crystal Mountain Green Valley 6230' at -15 °F (-13 °F yesterday). Camp Muir 10110' warmed substantially from -14°F pre-dawn yesterday to several degrees above zero today, with the overnight low of -6 °F occurring at 6pm last night.

At some of the lower-elevation sites, the minimum occurred right around sunrise, normally the coldest time of day (all other factors being equal). But at most mid-elevation and higher-elevation sites, the minimum occurred near midnight, even in late evening at several sites, as the air aloft has begun to warm significantly as forecast and as clearly seen at Camp Muir. This cold snap has peaked and is fading out, so almost all sites should end up being warmer tonight and tomorrow morning.

Note about the "-0" readings: apparently, the temperature sensors at most (all?) of these sites read in 0.1 °F increments, but are rounded to 1 °F increments for display online. Hence "-0" implies a temperature between -0.1 and -0.4 °F.
