The latest model shows a real strong warm ridge showing up. I'm so excited!

I think it's been a while since I did a temperature update for my area.

 

March had a Mean of +3.4. April was only a tiny bit below average with a Mean of -0.9.

 

Dec/Jan/Feb period was -1.9 here. Although January was a cold anomaly at -6.2. Interesting season. I really wonder how Spring will end up this time.

 

Oct-Apr period, extremely windy. This easily ranks far above any other water year for wind, and we're not done with the water year (still have YET to factor in my summer storm induced winds!!).

 

I was close to a few t'storms (saw flashes on 03/17 and there were weak convective echoes about 12 days ago near K-Falls).

 

Overall very diverse weather here I have been experiencing.

What defines an extremely negative NAO? Is it the ridge off the East Coast?

gfs_z500_mslp_namer_2.png


No, that's the Bermuda High. The NAO is defined by the NATL pressure differential by latitude. Look for higher than average 500mb heights near/over Greenland during a -NAO:

It was 49/32 on this day in 1964, at PDX. 

 

Absolutely tanked PDO (-2.31) and PNA (-2.68) that May, tanked Modoki zone B (-1.46, only lower value since was July 1970) following a transition from a Nino, and volcanic influences from the Agung eruption. Ridiculously cold spring and overall year for PDX. Interesting times.

I had a low of 25 on this date in 2013 I believe. Easily my coldest low in May since I moved here.

Great info. 1964 never gets talked about too much on here (aside from the December cold wave/flooding) but it was pretty impressive. PDX's coldest year on record, beating the next coldest (1955) by 0.4F, with an annual average of 50.1F. Normal for PDX is 54.5F.

 

Spring through early winter 1964 had a very impressive run @ PDX.  Fourth coldest March on record, second coldest April on record, coldest May on record, third coldest June on record, fifth coldest July on record, second coldest August on record, coldest September (!!) on record, fourth coldest November on record and then the massive cold wave in mid-December to top things off.

The Euro has been gradually coming around to the GFS, not cutting off energy as quickly late in the week, which leads to a bigger crash/cooldown for us Friday-Saturday. The 12Z looks the most impressive yet.

Warms up quickly again after that though. Some seasonably warm days. Although there have been hints of another big cooldown late in the ten day period as the cutoff low over California re-absorbs into a full latitude trough.

I looked up that year for Bellingham on Wunderground. It was maybe not as impressive here, but there was a day in December when it was 4.5 degrees at 10 AM! Sadly that day's full data is missing on Wunderground.

Yep, 2013. We caught the edge of that historic airmass sliding down the country's midsection. Snow down to Arkansas in May...

They came to the U.S. and were on Sullivan in February 1964, then the next month an unprecedented string of top cold months began!

Abbotsford hit -1F with winds sustained around 30mph. Agassiz dropped to -5F. Top tier stuff. Probably up there with anything outside of Jan 1950.

And a year later we had the only May snowfall that I'm aware of for the lower elevations of the Portland area on 5/5/1965, with some light non-sticking snow showers early that morning.

May 2013 was interesting. We ended up with a warm/dry first half of the month and then a wet 2nd half of the month. 

 

The morning of May 22, 2013 I woke up to wet snow falling with temps in the mid-30s. Had a high of only 43 at my house that day, Silver Falls recorded a high of 41 which tied their all time min max for May. 

 

Overall though I believe that month ended up slightly above average.

Ended April with a -0.1 departure. Highs were below normal, lows were above normal.

 

The 8.80" of rain I got was 2.6" above average. 

 

Departures so far this year:

 

January: -4.7

February: -1.2

March:    +0.3

April:       -0.1

 

February-April's lows were about +2, but highs were well below normal all 3 months.

Winter of '63-64 was pretty garbage, though. Kind of just bled right into the spring and gave us 6-7ish months of the same weather.

January 64' looks like it was pretty wet....

 

 

December 1964 wow... 24.30" of precip with the last four days of the month missing...Given the snow depth went from 0-10" during that time frame the true precip amount was probably in the 25-26" range...

Lows were below normal in February and April up here. Slightly above normal in March though.

It's possible your area is experiencing some UHI from the chicken coop.

It was 49/32 on this day in 1964, at PDX. 

 

Absolutely tanked PDO (-2.31) and PNA (-2.68) that May, tanked Modoki zone B (-1.46, only lower value since was July 1970) following a transition from a Nino, and volcanic influences from the Agung eruption. Ridiculously cold spring and overall year for PDX. Interesting times. 

 

OLM hit 26 with that air mass. 

 

Remarkably, that's not the latest they've seen a temp that cold. 5/7/2002 and 5/9/96 also both hit 26. Pretty astounding when you consider there are record lows in mid March in that range.

The setup on the 12z Euro is probably the best yet for a possible t-storm outbreak.

I suppose it's possible that there were more nights with clouds banked up against the Cascades thanks to a lot of moist westerly flow. We actually had quite a few mostly clear nights in the 30s up here last month.

That was not today at 1:50 p.m.    :)

 

Sort of looks like a hot day with a little smog in the distance.

This sounds interesting. From the latest AFD:

 

Most models sweep the next
short wave trough into the coastal waters Thursday night resulting
in the development of a strong marine push by evening, the
increase of upper level diffluence during the course of the day,
destabilization of the mid levels, and increased shear. The GFS
shows impressive lifted indices on the order of -3 to -6 Thursday
afternoon and CAPE values from Seattle southward of 1500-3000
J/kg. Then NAM is similar. MOS thunderstorm probabilities of 40
to 50 percent are shown in both the GFS and ECMWF guidance
products. This is about the most unstable I have seen forecast
models make things here in the Pacific northwest in my 25 years
forecasting here. It will be interesting to see how things verify.
At this time will extend the thunderstorm forecast westward to
include the eastern portion of the Olympic Peninsula

Sitting at 52/39 for today so far with low clouds and periods of light rain. The day after tomorrow is going to be a major shock to the system.

I was actually thinking about the same thing. Would have been fun times to be around.
 
They came to the U.S. and were on Sullivan in February 1964, then the next month an unprecedented string of top cold months began!

 
Little did those newly-minted Beatles fans know, but we'd never see sustained cold anomalies like that again. 
 
In all seriousness though, 1964 was a special year. The SAM (Southern Annular Mode) was also off the charts negative, so the southern hemisphere was out of wack as well. I'd have to imagine Agung played a role in this as well:

The SAM is directly correlated to poleward displacement of westerlies in the southern hemisphere, i.e. the more positive, the more poleward are the westerlies. In 1964 they were suppressed equatorward to a much greater degree than any other year since at least 1957.

Abbotsford hit -1F with winds sustained around 30mph. Agassiz dropped to -5F. Top tier stuff. Probably up there with anything outside of Jan 1950.

 

Pretty incredible CAA at PDX as well. Hit 6F in the evening hours of 12/16 with easterly winds of 20-25 mph.

And a year later we had the only May snowfall that I'm aware of for the lower elevations of the Portland area on 5/5/1965, with some light non-sticking snow showers early that morning. 

 

That's the latest Portland area snowfall I'm aware of as well. I remember Raymond Hatton mentioned sticking snow in the West Hills that morning, in that one book. Skamania Fish Hatchery actually recorded 0.1" at 440 feet.

 

We had an incredible run during that era. 1961, 1965, 1967, 1970, and 1972 all brought snow to the western lowlands post-4/20.

May 2013 was interesting. We ended up with a warm/dry first half of the month and then a wet 2nd half of the month. 

 

The morning of May 22, 2013 I woke up to wet snow falling with temps in the mid-30s. Had a high of only 43 at my house that day, Silver Falls recorded a high of 41 which tied their all time min max for May. 

 

Overall though I believe that month ended up slightly above average. 

 

I liked that May, lots of variety. That was a ridiculous cold trough on 5/22. Latest 50 degree max at PDX as well.

OLM hit 26 with that air mass. 

 

Remarkably, that's not the latest they've seen a temp that cold. 5/7/2002 and 5/9/96 also both hit 26. Pretty astounding when you consider there are record lows in mid March in that range.

 

That is pretty remarkable. Not much of a seasonal transition. PDX bears this out too - monthly records of 29 in both April and May.

Out of all the monthly record high/lows at PDX, April's 29 seems the weakest to me. They got down to 23 on 3/29/54 and 24 on 3/30/54. The strongest record would probably be September's 105.

Another sunny afternoon here in Victoria, but we managed a nice rainy morning/early afternoon to keep things in check. Looks like another possible shot at rain tomorrow evening through Wednesday and then again Thursday evening~Saturday.

 

Ended April with an average temperature around 50F and a little over 1.5" of rain; hopefully this month does better in the rainfall department.

Yeah, I'm surprised the April record has survived this long. We hit 31 in 2008, 31 in 2009, 31 in 2011, and 30 in 2012. You'd think we could have snuck down to 28 at some point in the pre-UHI era. 

 

I think I would actually pick the 100 from May 1983 as the strongest. Mostly because the readings in that event (like the 103 downtown or the 104 in Oregon City) have never been replicated in May. On the other hand, 105 degree readings were recorded in the I-5 corridor on 9/5/1944, so 1988 is not unique in that regard. 

 

In other words, its statistically less likely that we see another shot at 100 in May, than another shot at 105 in September....

Speaking of May 1, 1964 - Sitkum 1E, at 610 feet in the southern OR coast range, got 5.0" on that day. That might be the most impressive late season snowfall anywhere in Oregon.

UHI definitely complicates the "strongest record" thing, at this point breaking the January and February record lows is probably less likely than breaking any of the monthly record highs.

 

And good point about May, though we have gotten sort of close a couple times - downtown hit 99 on 5/22/01 (not sure about Oregon City, they seem to be missing data for that date), and going way back another 99 degree reading on 5/29/1887. 4 degrees is a pretty big difference however.

The trend definitely favors that line of thinking. Tough to imagine a reading below zero, when we haven't dropped below 10 in almost three decades. 

 

BTW, Oregon City hit 95 on 5/22/2001. It appears under 5/23 due to the 24 hour COOP reporting lag.

The models seem pretty adamant that we see a 60+ low on Wednesday night. If so it would be our earliest on record by about ten days.
