U.S. deep freeze continues; dangerous air pollution episode in Utah

By: Dr. Jeff Masters , 4:27 PM GMT on January 24, 2013

The January 2013 North American cold wave continued to bring bitter cold to much of Eastern Canada and the Midwest and Northeast U.S. this morning. In the U.S., below-zero temperatures were recorded Thursday morning in twelve states east of the Rockies. The most intense cold was centered near the Minnesota/Ontario border, where Embarrass, Minnesota hit -42°F (-41°C) and Crane Lake, Minnesota bottomed out at -36°F (-38°C). The coldest spot in Canada was in Souix Lookout, Ontario, about 100 miles north of International Falls, where the mercury fell to -40°F (-40°C.) The fun continued on the summit of Mt. Washington, New Hampshire this morning, where a temperature of -26°F (-32°C) combined with a wind of 71 mph to create a remarkable wind chill of -73°F (-58°C). A digression: back in 1986, when I taught weather forecasting at SUNY Brockport in New York, I worked with a meteorologist who used to work on top of Mt. Washington as a weather observer. He said it was standard practice back in the days he worked there to engage in a ritualistic prank whenever a new weather observer joined the staff. On the first day the new observer was there during one of Mt. Washington's classic hurricane-force wind events, he would be sent out with a safety harness and a can of paint to paint the observation platform. The unwitting observer would inch out into the hurricane winds, struggle to pry off the lid of the can of paint, and quickly discover the impossibility of painting during a hurricane--the powerful winds blowing over the top of the paint can would create a powerful Bernoulli Effect, levitating the paint out of the can and hurling all of the paint far downwind. The sheepish newbie weather observer would report back inside and ask, "you really didn't want me to paint the observing platform, did you?" to the sound of uproarious guffaws.

Dangerous air pollution in Utah
The most dangerous weather in the U.S. this week is occurring in the valleys of northern Utah, where clear skies, light winds, and a strong temperature inversion have combined to create a dangerous 6-day long air pollution episode. (A temperature inversion occurs when air temperature increases with altitude, acting as a stable lid preventing atmospheric mixing; inversions are common in mountain valleys when high pressure dominates.) It's been unusually cold during most of January in Northeast Utah, with Salt Lake City on track to have its 3rd coldest January on record. The cold weather has caused people to use their wood burning stoves more than usual, resulting in high emissions of smoke. More than 100 Utah doctors delivered a petition to state lawmakers on Wednesday, demanding that authorities immediately lower highway speed limits, curb industrial activity and make mass transit free for the rest of winter. "We're in a public-health emergency for much of the winter," said Brian Moench, an anesthesiologist and president of Utah Physicians for a Healthy Environment. He estimated that poor air quality contributes to 1,000 to 2,000 premature deaths each year along Utah's Wasatch Front.

Winds have remained below 6 mph for six straight days in Northern Utah, allowing fine Particulate Matter less than 2.5 microns in diameter (also called PM 2.5) to build up to unhealthful levels. PM 2.5, also known as particle pollution, is a complex mixture of extremely small dust and soot particles that lodge in the lungs and cause large increases in hospital admissions and excess mortality during severe air pollution episodes like this one. The federal standard for PM 2.5 is 35 micrograms per cubic meter, averaged over 24 hours. In Salt Lake City, fine particle air pollution has been above the federal standard for six consecutive days, with a peak value of 91 micrograms per cubic meter on January 19. In nearby Provo, Utah, the pollution has been much worse, with 24-hour average PM 2.5 levels more than triple the federal standard on Thursday morning, at 131 micrograms per cubic meter. If the PM 2.5 levels go above 150 micrograms per cubic meter, this will be in the "Very Unhealthy" category as defined by EPA. At this pollution level, the entire population is likely to be affected, and health warnings of emergency conditions are issued. Compounding the air pollution woes in Provo are high levels of nitrogen dioxide gas, which peaked at 98 ppb on Tuesday, just below the 100 ppb federal standard. Light winds and a strong temperature inversion will continue today, and freezing rain fell over much of the Salt Lake City area this morning, turning the roads into skating rinks, resulting in dozens of traffic accidents. Fortunately, the forecast for Provo calls for snow and rain this weekend due to a low pressure system, and the rain and winds associated with this low should be able to reduce air pollution levels significantly.


Figure 3. Observed air quality in North Provo, Utah, January 19 - 24, 2013. 24-hour average fine Particulate Matter less than 2.5 microns in diameter (also called PM 2.5) levels (black circles, top image) were in excess of the 35 micrograms per cubic meter U.S. standard (orange line) during the entire period, and peaked at 131 micrograms per cubic meter--more than 3 times the Federal standard--Thursday morning. Levels of toxic nitrogen dioxide (yellow dots) peaked at 98 ppb, just below the U.S. standard of 100 ppb, on January 22. Note that during the entire 5-day period pictured here, the wind speed at the surface never rose above 6 mph (lower image, black dots.) Image credit: Utah DEQ.

This is not cool at all

Yeah as much as people may not have liked the 2004,2005 and 2008 hurricane seasons we need a set-up like that to come back so the drought won't be as bad.After the 2004 hurricane season the south-east drought wasn't as bad.A matter of fact many people were above normal.Or at least a El nino.

But the mayor was optimistic there would not be much damage, given the city had already dealt with 600mm of rain in the past two days but only experienced minor localised flooding.

Pretty sick rains there; 23 inches in 2 days.


As for the Extra-tropical low, 16 meter wave heights is 52.5 feet, if anyone didn't do the math.

Glad I'm not a sailor. Three foot seas scared the hell out of me, lol.

Sounds about right to me. I don't know if the NAM and GFS have the best grab on this system. They may be underplaying the snowfall totals just a bit. Just looking at radar it seems that D.C. is definitely in line for measurable snow today. Most areas probably seeing 1-2, but like you said I would not be at all surprised to see some 3-4 inch amounts in localized areas, especially in the West Virginia Mountains and any meso-scale bands that may set up. The key factor in accumulations also will be dry air and how long it will take the precipitation to saturate the atmosphere. There is definitely some virga in there.

The clipper system surprised many with giving some areas 5 in a half inches of snow.This time the higher snow will not be concentrated there.More likely over our area.If the clipper can surprise then so can this storm and it looks like it has more moisture to work with.

We'll have to see if this keeps up during the hurricane season.The ECWMF is showing the atlantic being average to slightly below average in terms of moisture.However lots of the top performing models screwed up big time with the 2012 hurricane season.I think the "list" threw them off lol.(That list is associated with inactive hurricane seasons).


Yeah, we will have to see.

It is very icy and slippery outside.So people need to watch their step.Whatever snow is around has basically become ice.More snow to come today though.Their is a hint that since this is powdery snow we could fluff up to perhaps 4 inches.I'm hoping CWG dosn't sound to optimistic.

Oh yes.I forgot that even before the cape verde season(or hurricane season for that matter starts)you can kind of get a feel for what the wave ativity may be like for this year.If memory serves me correctly I think 2010 had strong thunderstorms very early on to and that year ended up having some pretty good cape verde storms that ended up being very strong hurricanes.

Also, the stream of T-storms coming off of Africa is pretty intense.

That's if the high sets up in the right place this year.If we want the drought to be relieved then a 2010 pattern would be the worst.However a 2008 pattern type set-up would be very benificial.However the strong storms aren't needed and Kori gets to track his cyclones.See everyone is happy!.lol.

We need some Tropical Storms to fire up to bring moisture and relieve the drought.

that's crazy. somewhere else i remember someone saying the mets underplay stuff. I think it was the Philippines when the big typhoons were barreling down on them. i tend to think that is not safe. granted, overdoing it like jb tends to do isn't great either. you have to have a middle ground, a balance, a happy median. :)

i guess in times like this you must take matters into your owns hands. keep an eye on the atlantic with the satellites and radar links. i'll be watchin' for you too, liz!! =)


I was the one that said PAGASA was massively underplaying Bopha. They only had Bopha as a Signal #2 with is winds up to 185km/h when even on the SSHWS Bopha was a Cat 5 280km/h super typhoon. If they had of put up a signal #3 maybe more people would of evacuated and not died, but we'll never know.

Schools closed today here in Dickson County -Mid TN. Just pre-ice pellet drizzle at this point, it's 33.6f. Kids are already playing Mindcraft.. Icey mix should soon arrive from the West and remain through noon or so.. I'm starting to think that the school administrators like snow days as much as the kids do..

This is not a major ice storm by any means, but it is producing enough frozen precipitation to cause travel troubles across Tennessee, Georgia, and North Carolina, where reports of road closures and accidents are coming in.

Good morning all. I'm just taking a quick peek of the weather before my day gets started. I have been busy all week with auditors so I haven't been able to enjoy the conversations on this blog. Thankfully, today is their last day which will be a busy one for me. Everyone have a great day and weekend.

To keep this on topic, the weather has been just beautiful here in the Keys. Cool weather, bright sunshine and light breezes. Couldn't ask for anything more. Be safe everyone.
