A fairly warm November but with some record breaking cold streaks… tons of records broken, low and high! And then there is what happened the first week of December!

Wondering about the cover image? This post was brought to you (unofficiallly) by the word EXTREME… or at least the 80s band…. hahaha.
(this is what you get when you type in “Extreme” in Google images. :D)


The December 8-11, 2014 Event for the record books:

First, lets do a recap of the extraordinary event that was the multiple punch storm that has affected us (and delayed this monthly summary!)

Rainfall and Temperature Highs compared to 30 year+ stations at Beaver Creek, Robertson Creek and City of Port Alberni stretching back to 1895.

Rainfall at Alberni Airport (AUT): 

Most intense multi-rainfall event ever recorded?

I looked at the days where more than 0.4 mm of rain was recorded surrounding the historic records listed above.  Total for the past 4 days is more than the multi-day events around the 1923 Beaver Creek record (4 days, 143mm), the 1993 Robertson Creek record (6 days, 231 mm), and the 1999 Robertson Creek record (6 days, 110 mm) so it is likely that this was one of if not the most intense multi-day rainfall event recorded in the Alberni Valley.

Temperatures high too:

Lets also not forget the record we smashed on December 9 from the post:

An incredible high at the Airport was reached: 14.5ºC almost a month record.

Beat the all-time Dec 9 day of 12.2ºC at Port Alberni in 1921 and 1957.   Also beat the entire month of December at Robertson Creek but not at Somass “A”. Previous was 14.0ºC and 15.6ºC respectively in 1976 .

#2 for December 8 and 10:
We reached 12.1ºC and *just* missed an all time record high for the day on December 8 (Monday).  The record at Beaver Creek, and Port Alberni City in 1938, 1939 and 1957 was 12.2ºC. We also set a short term record on December 10 of 13.3º C which was #2 all time to 13.9ºC set in 1926 at City of Port Alberni.

And lets not forget this:

Measured on the Vantage Pro II station.

Unfortunately wind records are not good for Port Alberni so it is difficult if not impossible to say how unusual that was, but I think we can rest assured a 103kph wind gust is a very rare event any time of the year.


The November 2014 Summary!

Temperatures above normal except lows at the Airport.

November switched gears from rainy October.  We ping-ponged from cold snap to warm outbreak.  In the end, the local differences between the warm Alberni inlet and the fog-influenced City stations showed daytime low temperatures slightly above normal against the cooler Alberni Airport location that showed overnight lows a full 1º below normal.

Maximum temperatures were well above normal and kept our overall averages near normal as well despite lows being below.


Rainfall half normal

Our normal rainfall for November is 345mm.  We received 55% of that number.


Records for the Month at the Airport since 1994

We set an amazing 11 new short term temperature records, 4 highs and 7 lows!  November featured its 2nd coldest end ever recorded and 2nd coldest middle ever.

Short term daily records set at Airport:

  • Nov 4 (high 15.4º C) #3 all-time 1900
  • Nov 9 (high 13.9º C) #3 all-time
  • Nov 13 (low -4.4º C)
  • Nov 14 (low -7.3º C) #3 all-time
  • Nov 15 (low -8.7º C) #2 (by 0.2º) all-time
  • Nov 16 (low -7.8º C) #2 all-time
  • Nov 17 (low -6.9º C) #2 all-time
  • Nov 26 (high 11.7º C) #3 all-time
  • Nov 27 (high 12.5º C) #3 all-time
  • Nov 29 (low -7.5º C) #3 all-time
  • Nov 30 (low -9.6º C) #3 all-time
  • Dec 1 was also a record low, and #3 since 1900

No rainfall records were set in November 2014.


Weak El Niño Predicted 

The December update showed El Niño still trying to present itself but not quite getting there.  There is still a 65% chance of El Niño being declared during the winter season and lasting into the spring.

The Models and Forecasters still expect a weak El Niño to form.


World Charges Toward New High Temperature

In  late November the NCDC released their October global report which showed October 2014 to be yet another record high month as many have this year.  The November report should be out next week…. The November report will show November 2014 was the 7th warmest on record according to NCDC (8th from NASA) , bolstering the case for 2014 being warmest year ever.  The oceans had their warmest November ever… that’s the 7th month in a row with warmest oceans ever… concerning with no real El Niño.  Land temperatures were “only” the 13th warmest, pulling the global figure down.

This graph is worth a thousand words:

The graph shows that the likelihood of a new global temperature record is very strong.

As I quoted from a news story last month, “2014 is already pummeling records without the aid of El Nino’s push.

The floor is rising when it comes to global temperatures.  Anyone who tells you we are in some sort of “pause” is flat out wrong.  As the graph below shows, 2014 (in green) and most of the years since 2000 are very much on top of the heap.

All years of record from NCDC/NOAA shows 2014 in green and other record high years in red.

Monthly Outlooks

As was the case in October, November’s monthly outlooks were pretty much useless.  September’s prediction for October showed below normal precipitation… we got almost the most ever.

October’s prediction for precipitation for November swung in the opposite direction with above average rainfall predicted…

November 2014 IMAE Forecast generated Oct

…. but we got half of normal…. which is what September said (below).

I’m not sure if I should bother with the month’s predictions but… it seems as though the forecasts aren’t available from their homepage anyway.  So maybe that is a sign. 😉

Happy rest-of-December!!

P.S. I’ve changed the format of the summary below so it doesn’t make for so much scrolling.  Hopefully it is still readable and understandable.

  1. Lots to chew on. I wonder if observing the weather changes it… very bead header picture: I had to live through this once and that’s enough. See my post over at RESH.

  2. Excellent summary as usual Chris! I was wondering about your records for December 11, 2006. It was a very stormy day with extreme winds, but Environment Canada only shows a maximum gust of 39 km/hr at 4 pm. I could have sworn I remember that a gust well over 100 km/hr was recorded by someone in Port Alberni on that afternoon – what do your records show for that day?
