Yesterday we had the first real freezing rain event that I remember experiencing. We've had rain when it's below freezing a few times this winter, but we haven't had any ice glazing objects. Yesterday everything open to the south-east, where the 10m/s wind was blowing from, was covered by a roughly 2mm thick ice coating. All trees rustled a lot in the wind because all the twigs were glazed in ice. Really difficult to get off windows. Gf's little brothers' school windows all looked like the kind of textured windows sometimes seen in showers.

I have a prediction - 2018 will be the hottest year on record.

I have a prediction - 2018 will be the hottest year on record. Is this a serious prediction? If so, I'm doubtful since a big El Niño is unlikely unlike 2015-16 |

Nah, was being sarcastic. Seems every year is the "hottest on record" since like 2000 lol.

Fake news. ICE AGE NOW. LOOK HOW COLD IT WAS IN FLORIDA THIS MORNING.
Nah, but in all seriousness there's been a shit ton of warming since 1980. Possibly a trend and will cool off to 1980 levels in the coming years?

The Jet stream has been mostly south of us for almost two months now, that is unusual. When that pattern flips we might get mild weather for weeks.
Despite this, we haven't really had any hard cold spells, and there have been many days with temps well above freezing, up to 7°C.
Røros has been below freezing since Jan 1., when they peaked at 0.3°C. Looking at the forecast, Røros will not see any temps above freezing at least for one more week.

I was looking through the historical climate data for London Heathrow weather station and I didn't realise how mild December 2015 was. I knew it was a milder than average winter but the values are as follows;
Average high C: 13.7
Average low C: 8.9

I knew it was a milder than average winter but the values are as follows; Average high C: 13.7 Average low C: 8.9 The warmth of December 2015 was very noticeable in NYC. It shattered the previous record warmest December by several degrees and ranks among the warmest Novembers on record, the preceding November and September were also the warmest on record. Average high: 13.5°C / 56.3°F Average low: 7.4°C / 45.3°F It’s interesting how NYC and London have similar December averages, and despite being 3,500 miles apart they managed to have a similar December 2015. |

Probably a climatic cycle that caused it. |

These are the temperatures we've had here this week, lots of showery 0-2C weather with diurnal ranges not really showing much of a pattern but with two sudden jumps in temperature when fronts have come over. That sudden jump back down on the morning of the 18th is very unusual for here.  |

Notice how they start to turn against climate change around the beginning of Obama's presidency.
Immediately after 2008, the coldest year of the 21st century (0.54C above average).
How shortsighted.
Side note, observe the consistent cold spot in the North Atlantic on recent global temperature maps. I wonder where a whole lot of cold water could be coming from? Water that until recently was ice is usually cold...

GFS has an ominous looking cold blast for Western Canada+US in the 11-15 day range. Still a bit far away, but damn, the anomalies look dark blue/puprle over there!

December 2010 (the antithesis of December 2015) was similar in that aspect as well. Cold both in the Eastern US and Western Europe, hell the cold even went all the way out to Russia. Usually high latitude blocking (Greenland blocking) will create a huge ridge right over the middle of the Atlantic, and big troughs on both sides of the ridge (Western Europe and Eastern NA). December 2015 must have been an opposite setup. |

That sudden jump back down on the morning of the 18th is very unusual for here. here's my temperatures for the week. Flat period around the 17th was during a long snowstorm, not really a storm just snowed lightly for a day and a half added up to 5 inches / 13 cm. After it cleared it dropped to the coldest of the week, -14°C around 8 am; nice light on the snow. Mild this weekend, though not abnormal for winter, just felt like it as we haven't mild weather and sun together for a while. Pre-snowstorm was kinda cold.  next week looks milder, though two ice days forecast with sun after a day with 12°C and rain. Should wash off all the snow before it gets cold. |

December 2015 must have been an opposite setup. Plotted both months from NCEP. Dec 2015:  Dec 2010 looked like it less a trough on both sides and more just everything to the south was cool  |

Looks like Dec 2010 was a simple case of cold air displacement to mid latitudes.
Interesting how Dec 2015 had such cold air really not that far from the UK...about 800-1000 east and the UK would have had record cold instead of record mildness.
