COLD THAT'S GONE FROM EUROPE APPEARS TO BE WORSENING INDIAN AND EAST AND SOUTH ASIAN COLD WAVE!
All the brutally cold air that was parked over Europe for 4 or more weeks appears to be "beefed up" the Siberian Cold Pool and indeed the southern periphery of this has sank further south than typical, making even sub-tropical or even tropical India shiver. Here in Scotland, our high topped 36 degrees, pleasant with no wind and abundant sun after some morning clouds. Indeed we have an inch of snow still on the ground but that's set to melt in coming days and we're likely to push 50 degrees (10C) in Glasgow and Edinburgh whilst over southern England, areas of the southwest and across to London may touch 55 or even 56 degrees (13-14C), all this thanks to the breakdown of the stubborn NAO to a positive, this transitions the atmosphere over the North Atlantic from high pressure to low pressure and this allows a generally west to east flow of air off the Atlantic. That stone in the stream is no gone, therefore Spain, Portugal across across to Italy can get warmer than that be bumbarded by Atlantic storms that normally we here in Britain would recieve.
I do believe that the larger, deeper expanse of Arctic air centered over the heart of Asian Russia and stretches into eastern and south Asian countries has been caused in-part by the Atlantic's push of warmth eastwards across Europe and all this cold, Arctic air has had to go somewhere, that being Asia.
The problem down the road to all this is the fact that models show not only a loss in a large chunk of this cold over Asia by week three and no, it doesn't appear to be returned to Europe. So, where does all that intense, large reservoir of severe cold go to? NORTH AMERICA! It's transported by a powerhouse cross-polar jet and basically adds to an already cold pool centered over northwest Canada and Alaska already. This even colder air now freezing much of Asia will simply intensify North America's reservoir of cold and with the liklihood of warming to take place over Alaska and Canada within the next 10 days as well as Siberia, it's worrying about how severe the cold will be when it pile-drives southbound with warm air aloft migrates up into Alaska and northern Canada... The same now being experienced over Asia, will likely occur over the USA soon!
VAGARIES OF THE WEATHER
INDIA & SUB-CONTINENTAL ASIA WEATHER
BY RAJESH KAPADIA
Spotlight on Cold Days Trend griping NW and Central India:
OMG! The days are getting really cold..yes…days temperatures in the NW plains and Northern regions of the sub-continent are lower than the day temperatures in the Kashmir Valley and Hills of Simla !
The humid N winds sweeping the Northern plains, and forming of ground fog due to a stagnant high pressure ridge sitting in the region (1016 mb), but evading the hills, are responsible for the cold biting days.
I have seen cold days in these regions before, but this spell is longer than the previous ones.
Unfortunately, this spell has taken its toll with almost 100 dead in India due to the cold.
On Sunday, 9th. Jan,:
In Punjab, Gurdaspur (AWS) measured only 6.5c as the highest in the day, Patiala 7.4c,
Kaithal (AWS) in Haryana recorded a high of 6.5c and Karnal’s high was 7.4c on Sunday !!
The maximum and Minimum temperatures on Sunday:
Amritsar:8.0c (-11c) -2.2c, Chandigarh: 8.1c -0.6c, Ambala:8.3c (-12c) – 4.5c,
New Delhi S’Jung: 11c (-10c) – 5.0c. The AWS station at Delhi (Mungeshpur) reached a high of 8.8c on Sunday, and Delhi (Narela) could manage 8.9c as the high today.
The NCMRWF station at Noida recorded a max of 10.3c today (Sunday).
However, as mentioned, the hilly regions are in the “normal” range.
The lower Himalayas hill stations (all over 6000 ft ASL) were not much lower than the plains, in fact, higher in some cases in the day on Sunday
In H.P., Solan was coldest in the lower hills with minimum temperature of -1.0c C while Sundernagar, Bhuntar, Dharamsala, Mandi and Una recorded a low of 2.c, 3..0c C, 3.3c, 3.5c and 4.7crespectively
Srinagar: Maximum 9.5c, Dalhousie was 6.5c.
In the Utterakhand hills, Nainital was high at 11.6c and Mussoorie at 9.5c.
The nights are bitterly cold too;
On the 9th. of Jan, the lowest temperatures in the plains were: :
Nal and Suratgarh : 0.6c, Agra 0.6c, Sidhi 0.8c, Phalodi 1.0c.
Panna (AWS) in M.P. was the cold at 0.4c,
Ferozpur in Punjab froze at 1c and Faridkot touched 1.3c..
Across in the plains of Pakistan too, the day temperatures have taken a dip.
Sialkot touched a high of 8c and Multan was at 10c
Similar trend is seen in Pakistan, with Muree, a hill station at 6000 ft ASL also reaching a high of 10c.
The lowest in the plains of Pakistan, was in Sindh, with Sibbi again, freezing at -2.5c !!
Well, like I mentioned in yesterday’s blog, I surely see this easing up from the 13th. In India and Pakistan.
With the pressure ridge dropping to 1010 mb initially, and thence to 1008 mb in the region, A fairly good W.D. is on the anvil, and is expected to precipitate rain/snow in Northern and NW regions of the Sub-Continent from the 13th. of Jan. It would be peaking in precipitation on the 14th.and 15th.
The current easterly wave is very active over Sri Lanka and extreme south of India.
It will penetrate into the Southern tip of India from Monday, but weaken subsequently.
I expect rains in southern T.N. and Kerala for a couple of days.

WILD WEATHER ON A WILD WORLD
MEXICO WEATHER
BY ARTURO SALINAS
Monterrey --> the city is experiencing strong gusty winds due to the developing winter storm over Texas that passed north of the city last night.
Sustained winds of 20-30 km/h with gust reaching 60 km/h at times have knock down trees, telephone lines and left areas with power outages. Today we'll reach 28°C and stay at a cool 15°C at night with clear skies but high winds. Now, next week gets tricky. Computer models have been consistent in showing just rain on the area but due to the orographic conditions of the city, I wouldn't be surprised if at least we see some snow or sleet at the mountains around 1400 meters and above; specially tuesday night-wednesday morning. And if more arctic air keeps pouring southward we could actually have some wintry precipitation in certain areas of the city above 700 meters. I think we'll need to wait just 24 hours before to be certain on what will happen. Indeed this week will be a very cold one for us down at the city with very damp conditions so precautions in water pipes, cars and children should be taken. READ MORE HERE!

After some morning clouds and even a few sprinkles, temperatures though only warming to a mere 36, felt quite pleasant under the afternoon sun and little in the way of wind. By afternoon slow melting was in progress.
Thanks for reading.
