That seems to be the way it works. With upper levels digging down to our west and ridged up over us it's no wonder we are breaking heat records and they are getting a late taste of winter. I wanna see a flip flop on the upper levels and see a cold March and a wet March for my area.

Too bad the cold air won't make it here, lol. At least no more 80's in the forecast, but no highs below 76F for the remainder of the week.

Got up to 82F here this afternoon tying the previous daily record set in 1986. Last night's low was 65F. Pretty windy today with gusts up to 35 mph.

Could get heavy rainfall tomorrow, though the heaviest will probably stay to my northwest. Small severe risk also.

We haven't dropped below 28F yet. Tonight is the only chance.

As far as the surface... i am seeing record cold across the West. There's always going to be locations that dont break...doesnt mean its not an arctic/extreme airmass "aloft".. you know?

Yep, very impressive for the inter mountain west. No debate there at all. However, not so much for coastal PNW (SW BC in particular).

Last one.. Lets use the 925mb temp air mass now.. (2500')... For Oregon... Has it been colder? Of course.. But what side of the extreme is it on and how low is it?


How about we agree to call it impressive instead of Extreme. I think It's not often the PacNW gets an airmass this cold. Right?


BTW -- These are actual observations, not model forecasts.

The numbers speak for themselves. I guess this is pretty impressive for Oregon.

I should have specified SW BC in my post. Most winters do usually break -10C for 850mb temps here. As previously mentioned, it is not as common these days (post 2000) as it was before. However, it is by no means extreme. Something extreme would be sub -20C 850mb temps which we've only seen a few times before(Jan 1950 and '69).

I suppose the thing that gets me is that I constantly see the east smashing cold records dating back over a century and I think that's possible here. For example, Toronto's coldest month on record was just set in Feb 2015; something equivalent to that would be Vancouver breaking Jan 1950's record.

Today's high at LEX was 80°F. Ties the monthly record.

Louisville set a new February record high for the second consecutive year. Hit 82°F there!

Warmer climate, horrible trends, and allergies in February. Guess I have to move 1500 miles further north again.
