It's been snowing all day here, and melting slowly. Just above 0°. The ground's covered in a deceptive slush that looks fluffy but turns to water as soon as tread upon. Roads deformed by tire tracks and salt. Should freeze tonight, so grotesquely uneven icy pavements will line the trench-like roads and make for challenging movement in the morning! :)
Icy today. Leftover snow slowly melting. Cold winds. Just below zero. Typical early winter weather.
Snow today. And rain. Few degrees above zero. Slippery surfaces and slush, cars skidding around and people sliding across the concrete like cakewalk.
Another day of the same weather. The ground is growing green again, barren and blemished with streams of spread out stones and gravel. A couple degrees above zero.
Nothing out of ordinary. In about a few hours a cold front will cross the southern China and if the forecast low on the next day falls to 12 degrees Celsius or below, HKO will consider issuing the cold weather warning for the first time since the arrival of winter. It will be mainly fine and dry during the next few days, so the New Territories will be a few degrees.
Interestingly, the typical time for the first intense cold surge to arrive in recent years is also mid-December.
Approximate position of the cold front at 8pm local time.
I placed the front just behind the first isobar of the cold core high, where north winds and pressure gradient appears to be the strongest.
Cold and windy today. -2C. Barren fray. Remnants of snow line the gray roads and gravel ways.
Soft rain, snow gone, darkness.
Current supposed weather status (they've got the lack of rain thing wrong) in local untranslated probably slightly cryptic form:
Moonlit skies tonight! Nice and quiet, no snow yet but otherwise it feels like Christmas's on the rise...
Oh nice we can tripple post now
Anyways its 38 F light rain today.

Three different days in the row though. ;) Was hoping someone else would post something soon, started to seem like I was hijacking the thread...

Sounds like summer. :) We've got clouds, and now past the darkest day of the year the world is warming up...
Not seeing the promised sunshine, but a cool coat of clouds that light up like a dim-lit lamp. Misty weather.
Here we go just today before leaving for work

Oh you've got snow! Nice. Still nothing here...
More clouds... with a few diffuse rays of sunshine! Brighter days ahead...

Ground Zero. O_o
A few below over here, finally maybe some actual winter...

That sounds pretty harsh! :O Visible degrees don't really do that message justice...
Happy New Year.
During the past few days, a ridge centered over Alaska and the North Pacific contributed to northerly flow ahead of the ridge center. This resulted in widespread cold waves across much of the North America continent. A weak shortwave ridge over Central Asia has propagated eastward, and was also contributing to below normal temperature conditions across the northern part of East Asia. Zonal westerly flow aloft due to positive NAO kept cold air across Northern Europe from intruding southward, hence average temperatures were slightly above normal for much of Europe.
Upper level analysis from CPC indicates that positive height anomalies had propagated from the stratosphere to the troposphere. The present North Pacific ridge (resulting to arctic outbreak across North America) may be linked to that propagation. This analysis also shows that geopotential height anomalies near the upper and middle stratosphere have turned positive, hinting at a stengthening polar vortex.
The North Pacific ridge will weaken over time and as a result, more zonal flow is expected across North America and cold air (especially at lower latitudes) will start to moderate after Week 1. This is also consistent with the expected synoptic-scale pattern based on current SST.
Energy transfer from the troposphere towards the stratosphere is not expected to increase dramatically. Stratospheric vortex should stay strong. Thus, AO index should be near neutral to slightly below 0 (in view of deficiency in Arctic Sea Ice)
The energy associated with zonal westerlies across Europe will support downstream ridge development near the Ural mountains. Another surge of cold air is expected to arrive East Asia next week. With the development of a trough, it will be colder in Western Europe as well.
Here is the experimental 14-day probabilistic forecast from HKO:
A cold front crossed the coastal areas of China yesterday. It is rainy today so daytime temperature remained below 10 degrees Celsius. Most places saw minimum temperature of 6-7 degrees Celsius.
The temperature at Tai Mo Shan (a mountain peak at 955m above sea level) fell to -0.8 degrees Celsius in the morning. This is the first time sub-freezing temperature was recorded by an automated station since the intense cold surge in 2016 (the record low was -6 degrees Celsius at the peak on 24/1/2016)
PS. As usual, cold air mass is quite shallow and the cold front has a tilted structure (tilted towards the north with height). It remained well south of Hong Kong at sea level, but lingered near Hong Kong at an altitude of 1 km above sea level. So temperature recorded at Tai Mo Shan fluctuated a lot.
The tilted cold front brought warm and moist air aloft, which led to cloudy and rainy weather throughout the day.
Shite, it's nowhere near proper winter temperatures, not cold enough for any frost or snow whatsoever. Just rain as usual.
Cloudy and dark
I like it actually.
It's just like my soul.

Widespread persistent cold across Europe following a major disruption of the stratospheric polar vortex.
The sudden stratospheric warming event which captured media attention was partly a result of a very robust MJO event during easterly QBO phase.
It's like this. Real winter! Finally. And for a full week so far.
Seattle Washington
30s. Cloudy rainy wet. This is the normal around here. And Mt renier has not blown up so it's all good lol

Bridgeport, CT (2-Mar-2018 17:00) - Rainy, windy, gusts to 60MPH, some sleet, roads suck and it's a dark and ugly sky. Crappy way to start a weekend.
