TODAY'S WEATHER ACROSS UK & EUROPE
By Mark Vogan
This week may see major European cities warm to levels not seen in 6-7 months!
A 13 or 14C high for Moscow would be the warmest since November 10-11th, for London, a 21C high by Thursday would be it's warmest since October 8th
For the first two days of April, 2011, Moscow has warmed to 4.7 and 5.9C respectively but as of 7pm this evening, it's a balmy 11C. Moscow has likely topped out at 13 or 14C. This would in fact soar beyond the past two days and first two of the new month. This is also the warmest readings for the Russian capital since way back on November 10-11th last year which was 13 and 14C and as well as that, the normal for the first few days of April is only 5C and the normal low is -2C. Incidentally, Moscow just two nights ago saw a low fall to -9C or 16F.
LONDON MAY REACH LEVELS NOT WITNESSED SINCE SEPTEMBER!!
By late this upcoming workweek temperatures in and around London may well top 21C for the first time since way back on October 8, 2011 when it also reached 21C or 70F. However, it's very possible that it may reach even warmer than 21, perhaps a 22, even 23C isn't out of reach by this upcoming Thursday, that's a warm 73 or 74 degrees F. Would you believe that not only would this be the warmest readings since September 22, but also the warmest during all of September for London Heathrow was only 23.9C (75 degrees), so it may actually get close to reaching that by Thursday. Incidentally, the warmest so far was 18.8C or 66 degrees which was last month.
As for the UK as a whole, the warmest so far was firstly reached on Friday last week in the northern Scotland town of Lossiemouth, located along the Moray coast where it reached 19C in the sun. The warmth here in particular was likely boosted by a strong southwest wind which likely downsloped off the northern Grampians. Those hills also stopped rain bearing clouds which brought heavy, thundery rains over the west, northwest Highlands from reaching the more sheltered Moray coast, helping both sun and compressional downslope winds to warm this northern town to Britain's warmest levels since 2010.
Yesterday however, saw a 20C or 69 degree high at Writtle, Essex, marginally besting that of Lossiemouth's the day before. These numbers will be long forgotten about come late this week as highs in the southeast of England likely see temperatures not witnessed since at least October, if not September last year.
BRUSSELS, BELGIUM 20-25F ABOVE NORMAL, MAY TOP THAT LATE THIS WEEK COMING!
Even in western mainland Europe as strong southwesterlies blow and unusually warm high pressure pulling up from Spain and the western Sahara, temperatures though warm last week, may quite easily surpass what was the warmest readings of 2011 so far in the cities of the low countries.
Incredibly, Brussels, Belgium saw a toasty 23.4C (74 degrees F) high yesterday which in fact was way way above the average high of just 12C, later this week, whilst southeast England climbs into the low 20s C (low 70s F), so too will cities across the North Sea in the low countries. Belgium will take another run at those incredible levels witnessed yesterday.
AMSTERDAM, HOLLAND SEES HIGH 14C (25F) ABOVE NORMAL!
Belgium's neighbouring cities also saw incredible April 2nd heat with a very warm 23.2C (74 degrees F) recorded at Amsterdam, Holland, that's a huge 14C or 25 degree F above normal.
IT WOULD TAKE A LOT TO BEAT YESTERDAY'S 25C HIGH IN PARIS, LATE WEEK PATTERN DOESN'T FAVOR JUST AS WARM... WHY SO WARM HERE ANYWAY, PERHAPS BLAME WEATHER OVER SCOTLAND?
If you thought both Brussels and Amsterdam was warm yesterday, try a 25C or 77 degrees F at Paris, France, helped perhaps by lower pressures, sliding across Scotland which excellerated a southwesterly flow over northern France forcing hot weather over Spain to cross the Pyrenees and funnel between the Alps to the east and the strong boundary sliding east over the UK. This set up with the near 30C air over Spain being forced north, northeast at high speed meant little time to moderate as it progressed north. The flat topography of the region from central France to northern Holland was also likely a big influence. The cooling effects of the nearby North Sea was'nt there simply because the sea was underneath the boundary and not to the east where the hot air was blowing north, directly into these lowland cities of far western Europe.
WITH LESS LOW PRESSURE OVER SCOTLAND AND LESS SOUTHWEST WINDS FORCED UP FROM SPAIN LATER THIS WEEK, IT'S LIKELY TO BE LESS WARM IN PARIS, BRUSSELS AND AMSTERDAM
It's likely to warm into the low 20s C later this week in Paris, but to beat yesterday's extremely warm levels, well it's unlikely. The thing to remember is that the core of heat was over northern France yesterday and the pattern overall across western Europe and the UK was perfect for the exceptional warmth found in Brussels, Amsterdam and Paris. Scotland saw a boundary slide in from off the Atlantic which helped areas further east to see strenghening southwest winds. By lower pressure moving east over Scotland and towards a strong high pressure over Spain this tightened the pressure gradient. The fact that Spain was seeing very warm spring heat (25-30C) and winds blew strong from here northwards, this allowed these three cities (Paris, Brussels and Amsterdam) to see yesterday's amazing warmth.
With warmer air spreading north once again this week but further west and shared with the UK, that southwest wind won't be blowing as hard from Spain, therefore, without a powerful southwest wind aligned and funnelled purely over 'mainland western Europe' means, the core of heat isn't as concentrated over the mainland as much as yesterday, The warmth, though well above normal is shared more widely, therefore temperatures won't get as warm as they have done in Paris, Brussels and Amsterdam but London all the way to Glasgow will likely see their warmest levels of the year so far.
WEATHER TALK

Plains warmth today will spread to east tomorrow as 70s return to DC, Baltimore and Philly
DOES RAINS HOLD HIGHS IN 60s FOR NEW YORK, 50s FOR BOSTON??
It seems like it's been a long and agonising wait since that very warm weather back in mid-March which brought upper 70s to 80 degrees across the Mid-Atlantic and Northeast. Well tomorrow sees the return to warmth as the storm system which brought the heavy rains and interior snow to New England slides well off the Atlantic Seaboard and high pressure moves in and eastwards. That shift east of the high pressure core allows the strong southwest wind to blow and thus hurl Southeast origin warmth up the I-95 corridor.
VAGARIES OF THE WEATHER
INDIA & SUB-CONTINENTAL ASIA WEATHER
BY RAJESH KAPADIA
This weekend (Saturday/sunday), A1 is precipitating rain/snow in Northern Indian states of Kashmir, Utteranchal and H.P. Rainfall in patches was also reported from Punjab/Haryana and Delhi, where several places recorded between 1-5 mms of rain. Todats rain chart from IMD shows the rains in Northern India, Kerala and NE states. Compares well with Vagaries forecast map.
Fresh snowfall and rains occured across the Kashmir Valley today. Gulmarg received light snowfall while other high altitude areas, including cave shrine Amarnath got snowfall too.
Highest in India was 41c at Jharsuguda.
A1 will fizzle out from India by Wednesday. Mon/Tuesday will see precipitation in the hilly states, while plains of Northern India will be dry.
However a drop in day temperatures by about 2/3c from current levels is expected in Punjab/ Haryana/ Rajasthan and U.P. on Mon/Tues.
Meanwhile system has moved away from Pakistan, and resulted in cooling the regions of Sindh and Punjab from the rising summer heat.
Highest temperature in Pakistan was only 39c at Dadu.
And A1 has now crossed into Nepal. As forecasted, there was rain in the Kingdom on Sunday. Pokhara and Taplegunj measured 5.7 mms of rain. Cloudy Sunday in Kathmandu kept the day at 28c and the nights very comfortable at 11c. System rainfall will move away after Monday, restricting the precipitation to Central regions on Monday.
A resultant induced low is expected to form over North Bangladesh by Monday. Northern regions of Bangladesh can expect heavy thundershowers on Monday and Tuesday.
Coastal Orissa will be wettish on Wednesday.
Next 4 days temperature and precipitation forecast will be put up on Monday, 4th. night.
Meanwhile, it was 43c in Dadu, Sindh a day ago. Very close to our poll figure of "first to reach" 45c. Only 29% have put in their votes for the time period 1-10 april.
