WEATHER TALK
By Mark Vogan
Temperatures Soar Well-Above normal across Europe after widespread snow and severe cold just last month, but the cold/snow isn't done with Europe this winter yet!
Current 500mb chart shows much of Europe warm with even the ridge poking up in southern Norway and Sweden but this Atlantic airflow is sparking heavy, significant snowfall to the large cities of Oslo, Stockholm and Helsinki
This chart which is for Saturday 22nd, shows the ridging building just west of Ireland whilst a large trough re establishes itself over Europe as snakes a colder flow all the way around the ridge and into Spain and the western Med, fresh cold pushes into western Russia, the Baltics and also Scandinavia
BRITAIN TO REMAIN MILD BUT GREENLAND TO THE WEST AND CENTRAL EUROPE TO THE EAST WILL FEEL CONDITIONS GROW COLDER FROM JANUARY 20-25TH.
After a very mild period over the past couple of weeks across a large chunk of the continent, unfortunately, if your tired of the cold, snowy weather and wanted to see a continuation of the milder, Atlantic air, your not going to be happy as troughiness and cold air looks set to return to Europe but it appears, milder weather continues across Britain for the next 10 days where the ridge will poke northwards.
Because of the position of the ridge (warm pool) centered almost due north and up into Britain, this sets the trough axis to drop south over the heart of Greenland and with it's nature of building exceptional cold, it looks as though this vast iceworld will experience it's coldest air of the season thus far after what has been a fairly tame winter for this normally harshly cold region. Here across the interior, well away from moderating influences of the cold north Atlantic waters and over high-elevation iceshelf, temperatures may tumble towards -70F in the next 10-days. As for areas east of the British ridge, it's a return to colder/snowier times for central and NE Europe.
Note that this chart here shows the further east position of the ridge centered almost perfectly over the heart of Britain, this allows warmer air to push back across Spian as well as much of western Europe which got in on the tail end of the central Europe trough. Notice the extremely cold air setting up over Greenland and it would appear that colder air is trying to ush south towards Moscow and a large section of eastern Europe north of the Black Sea.
Period from January 25th through February 10th may see Britain cool and snow to return in a widespread fashion (UK cold and snow return will be discussed in coming posts).
VAGARIES OF THE WEATHER
INDIA & SUB-CONTINENTAL ASIA WEATHER
BY RAJESH KAPADIA
Sunday, 16th. Jan, sees Severe Temperatures in North India:
Kashmir: Shyok: -31c, Drass: -23c, Pahalgam: -16.1c, Gulmarg:-14.2c, Kargil: -13.4c and Leh:-8c.
Today, Sunday, it was the Valley which shivered, and Ladakh region was a bit “better”. The sudden plunge in the minimum temperature across the Valley was due to the heavy snowfall on Friday,
In H.P. Keylong was coldest in the state at -12.7c. Kalpa was at -9c, and snowfall on Saturday was heavy in some areas.
Shimla experiencing its coldest night of the season on Saturday. The capital saw 5 cm of snow too on Saturday. Water in taps in residential areas located in Shimla's US Club and Jakhu hills remained frozen throughout the day.
On Saturday, Uttarakhand with the higher reaches received heavy snowfall. There was heavy snowfall in Garhwal and Kumaon Himalayas including Badrinath, Kedarnath, Gangotri, Yamunotri, Auli, Nandadevi. Rainfall coupled with hailstorm in lower hills and plain areas intensified the cold conditions in the state. The state capital Dehra Dun, which also received a hailstorm followed by rainfall, recorded a maximum temperature of 14c, four notches below normal.
South India:
Cold wave conditions in interior Karnataka and A.P. prevailed on Saturday/Sunday.Temperatures could drop in Bangalore next 2 nights.
Agumbe was 7c on Saturday, while Rentachintala, Belgaum Airport and Haveri recorded the lowest minimum temperature of 9c.
The Nilgiris are witnessing low temperatures, with Ooty touching 4c on Sunday. With more clear nights in the next few days, frost has been forecast for the Nilgiri hills region.
With the upper winds set to change from the prevailing North- Easterly direction, I see the NE monsoon winds retreating from the region in a couple of days.
Nepal: As forecasted, hilly areas of Kathmandu witnessed snowfall on Saturday night/Sunday owing to the western disturbance.
This is the second time this year that the hilly areas around Kathmandu have witnessed mild snowfall, the first one being in late December considered normal.
However, Neeraj from Khatmandu mentions of very light snow in the city.
Quote Neeraj: “There was light rainfall in kathmandu today. It had drizzled a little early in the morning, the day was mostly cloudy and it started to rain at around 3:45 this afternoon. There are reports of widespread snow in most of the mountains surrounding the Kathmandu valley, and interestingly enough there was slight snow flurry in the valley floor too..It was not there in the city center but many locations in the outskirts reported seeing dusting of little bit of snow. I was lucky enough to have just two flakes land on my jacket..Just two flakes, and then it was all rain".
Snowfall in Manang and Lamjung since Saturday evening has grounded flights in Manang and stranded trekkers along the Annapurna circuit. Snowfall has also affected normal life in Lumle of Kaski district.
The W.D. has moved as a very feeble current into the NE states of India, and should fizzle out in a day.
Pakistan:
Yesterday’s projection of -1c in Islamabad proved correct. The capital was below freezing (-1c) on Sunday morning, and Karachi was at a low of 7c on Sunday.The Lowest in the plains was again at Nokkundi, which froze at -3.9c.
The below normal temperatures will rise to normal levels, as a W.D. approaches the Sub-Continent.
