I would have easier time buying this in January or December, because of sun angles. I think any march event would have fairly supportive upper level dynamics, not just a thin 850-700mb layer.

 

The -20c 850mb line does briefly cross into MT around 192 on the 12z Euro.

I'm just looking at your signature and it says you have to go all the way back to 2011-2012 to see a good snow year. This year will probably only end up being decent. I feel like 1600' in north oregon cascades foothills should be doing a lot better, maybe a 40" average in past 5 years.

 

The past few years have not had much in the way of cold onshore flow which is what really racks up the snow totals here. 2007-08 probably had close to 150" here, and 2008-09 and 2010-11 probably had 75-100". 

 

It is interesting, good setups for valley snow are not always good setups for snow here. I think March 21, 2012 was the only time since I have lived here where the valley had widespread snow and I got signifcantly more. December 14, January 7th, January 10-11 this year the valley did better, and February 2014 I got about the same as the valley. 

 

Often with the overrunning types of events the foothills get warm nosed, it happens more often than you think and it happens even with pretty weak WAA.

Unless the (low frequency) domain of anomalous tropical convection shifts east of 140E, this setup favors a very troughy spring and summer across northwest North America, including the PNW and Northern Rockies.

Don't tell me you forgot, 3 of the past 5 winters were drought seasons. Probably should check out my signature as well ;)

 

The cascades did horribly during that time period.

Looks like the last 6 days of February made a significant impact on my warm running Mean (was +4.8 first 22 days), now the Mean for last month is +1.6 from normal. High was actually -0.6 (was +2.4 first 22 days), with the Low at +3.9. Well that deescalated quickly... ;)

That's actually what happened in March 1951.

 

I sure hope we find a way to follow the 1951 template for the rest of spring as well.

Not a lot of ensemble support for the 12z Euro's crazy pattern evolution days 7-10.

Par for the climo I suppose. Although I would not complain about a March 1951 redux at all.

I agree, that was a very nice Spring.

I wonder if the long range pattern signals Phil is picking up on favor troughing centered slightly to our east. That is where 1951 went later on.

You would have been on the lake many times in April that year... lots of warm, sunny days.    Although the nights were cool.  

 

1951 featured one of the nicest months of April ever.   Rain on only 4 days... many days in the 60s and 70s and some low 80s.  

 

The summer of 1951 was also spectacular.

Need to get through the "spring barrier" for lower frequency tropical predictability first, but I think there's a good chance this will be a cooler, troughier summer than 2016 was. I'm just not sure exactly where the offshore ridge will set up.

Could set up near/south of the Aleutians like 2011, with the corresponding trough over the coastal PNW/GOA. Or it could set up slightly farther east, in the GOA, which would be a cool/dry pattern as opposed to a cool/wet pattern.

All depends where the convection sets up during M/A/M. If you'd like links to sites that track this, let me know.

Yeah, it's hard to tell how it was at Mossman's. I tried to look up Arlington but the wunderground calendar feature didn't go back that far for that location.

His area is usually colder than my area in the warm months and warmer than my area in the cold months.  

 

Out here in April 1951 there were 15 days at 70 degrees or warmer and 3 days in the low 80s with measurable rain on only 4 days in the month. That is about the most perfect April possible around here.   :)

Look, you had your winter. Can you just **** off and let us normal people enjoy some good weather now?

I'll be bummed if it's dark and rainy all summer.


I'd love that kind of spring, do I get to **** off too?

His area is usually colder than my area in the warm months and warmer than my area in the cold months.

Out here in April 1951 there were 15 days at 70 degrees or warmer and 3 days in the low 80s with measurable rain on only 4 days in the month. That is about the most perfect April possible around here. :)


That's amazing. Even down here there were only ten 70+ days and one in the low 80s.

70 degrees or better on 4/2, 3, 6, 10, 11, 12, 14, 15, 16, 22, 23, 24, 25, 26

 

I miscounted though... 14 days not 15.

I sure hope we find a way to follow the 1951 template for the rest of spring as well.     

 

The following the templates of previous year thing always works out.

That's very warm. How does it compare to April 2004 for your area?

I remember that being a great month as well.    

 

Looks like 10 days over 70 that month and 3 of those days in the low 80s.

I was surprised to see there was still snow cover here this evening when I got home. Still a solid 2-3". Hasn't been below freezing in about 36 hours. 45/35 so far today.

Hard to complain about the ECMWF today. That would really be a cherry on top for this winter if it verified.

About the best pattern you could ask for for widespread lowland snow in March. Especially later on in the run. Very 1951-esque.

Look, you had your winter. Can you just fuck off and let us normal people enjoy some good weather now?

 

I'll be bummed if it's dark and rainy all summer.

 

Take a deep breath.

 

Some of us like cold and dark weather, and would like to somehow magically have the climate of the Faeroes transplanted over our homes.

I looked up their climo and we are pretty close November-March.

 

The rest of the year is way warmer here on average, though, which I'm ok with.

Feeling some deja vu on this one, looks very similar to the setup that was predicted last Sunday. That one turned out to be a dud, this will probably be even more marginal so we'll see. Otherwise, things look pretty unremarkable on the 0z GFS; incredible how different this is from the ECMWF.

You can sure why the ECMWF took the path it did. Not the most likely outcome, but still possible.

One thing Tim didn't mention about April 1951 is the abnormally cold nights. There are places near Seattle that dropped to 20 well into the month. Bothell had 20 mins of freezing or below. It would be interesting to follow that year. 1951-52 was a cold weak Nino winter.

Probably a shot of a few inches of snow up here, and not a ton more...Depends on moisture. About a 48 hour window for accumulating snow. Definitely not looking like anything more significant than last weekend, though maybe slightly cooler. So could put up and impressively cold 35/30 type day here Sunday.

I did say the month featured many warm days and cool nights.

The WRF shows it certainly cold enough for snow Sunday morning with moisture moving through. Looks like a pretty good setup.

Pretty wide swath of snow shown for southern BC that morning.

A lot of uncertainty in the GFS ensembles but they definitely leave the door open for a mid month cold snap.

Accumulating snow in March in PNW is by definition heavy snow. At least the rates are.

Accumulating March snow is extremely common in the PNW. Just not in the lowlands below 1000'.
