What a difference one Friday to the next makes!

I was fortunate to have enjoyed this very warmth last Friday whilst walking around the streets of New York in my shorts and t-shirt. The actual high topped a record-tying 77 degrees at Central Park while it reached a record breaking 76 degrees at Philadelphia and 76 degrees at Atlantic City. The warmest spots were Newark, New Jersey and Pottstown, Pennsylvania where they both topped 80 degrees, both record highs for the date.

Last Friday (18th)

Since Friday of last week, it has gotten considerably cooler, in fact downright cold with lows this morning falling into the 20s even at both Central Park, NYC and Philadelphia whilst outlying areas fell into the low 20s with wind chills in the teens. If you live in this region, you'll have likely witnessed snow, hail and even some thunder and lightening during the passing of the recent storm system which produced upwards of 11 inches of snow around New York City...

Current readings this afternoon!

That is a cold night in store for Northeast, these numbers may be conservative in areas with several inches of snow on the ground!

TODAY'S WEATHER ACROSS UK & EUROPE

A MAJOR SCANDINAVIAN TROUGH OF COLD AIR SHIFTS HIGH WEST OF UK, TURNING WINDS OUT OF THE CHILLIER NORTH, NORTHWEST

TODAY MARKS FIRST DAY OF COOLING TREND AFTER HIGH'S IN THE 14 TO 18C RANGE ACROSS UK


Warmth stretched from Ireland to Germany throughout this week!

Over the past week, we've enjoyed good spells of warm sunshine throughout the UK thanks to a dominating high pressure cell. The combination of large-scale sinking air and a strong late March sun as well as longer daylight hours has allowed temperatures to reach a toasty 18C (65 degrees F) a few days in a row over England and as warm as 16C (60 degrees F) as far north as Glasgow and Aberdeen. Now that's pretty warm for March as one must keep in mind that surrounding waters are at their coldest levels of the year and any wind blowing off them often means chilly temperatures over land.

As for much of continental western Europe stretching way into Germany and even Poland, temperatures have been comfortably above normal thanks also to the influence of this west to east oriented high.

Cooler, cloudier this weekend through at least Tuesday next week!

Here is the European for today, if you notice when comparing this from the above graphic which was for Tuesday earlier in the week the cold has filled Scandinavian airspace. Also note the isobars oriented northwest to southeast across Scotland, this shows the ushering in of cooler air and I can vouch for that when steeping out this afternoon, it's noticably chillier. The far south of England remains warm as well as much of France, southern Spain (there is heavy showers effecting interior Spain including the Greater Madrid area) and over southern Germany but the influence of this trough is chipping away at those very mild temps that were in northern Germany, Denmark and into the Low Countries of Belgium and the Netherlands. 

Though the core of cold will remain well east of the UK, that very trough transporting the unseasonably cold air and snow well into the Baltic states and even down into the Ukraine will very much bring us here a return to much cloudier skies and with both cloudier skies and a northwesterly flow of air thanks to the high pulling northwest from Scotland, this will mean high for Glasgow, Edinburgh and Dumfries will only warm to around 7-8C (45-47 F) and for London and Paris 10-12C. A rather sharp drop from the May-like 19 to 21C readings of this past week.

As for the Scandinavian cities of Oslo, Stockholm and Helsinki and the Russian capital, Moscow, not only is there a further possibility of seeing yet more snowfall but highs will only warm to around -4 to -6C with nighttime lows of -8 to -12C. Those are levels more for early February and not the later days of March. This only makes what has been a long, tough winter, even longer for this frigid region.

Here is the European for Sunday March 27, note the blue competely covering Norway, Sweden, Finland with the core spinning over northwest Russia. The power of this trough is overriding that of the Atlantic high, pushing it way northwest, enough so that southern Greenland will be the beneficiary of some warm southerly winds from this high.

VAGARIES OF THE WEATHER
INDIA & SUB-CONTINENTAL ASIA WEATHER
BY RAJESH KAPADIA

In our Monsoon Watch Series, readers may remember that if the event of La Nina or El Nino is present, it is considered as one of the parameters in calculation of our forecast.

Ananth, in reply to your query:

Similarly, this event could also be effecting the sub-continental summer. A La nina this year, though moderate now, and a negative IOD, will reduce the number of W.D.s , (not cease them), but not in excess too. Thus, summer rains may be just about normal in the North, indicating that heat may be excess in the Kashmir/H.P. region, but around normal rains in the plains of the Northern Sub Continent.

Sindh and Rajasthan may heat up a bit, but not too excessively.

Similarly, La Nina usually sends easterly waves during the summer months to the southern peninsula bringing some more than normal rains. Hence near normal summer temperatures for the peninsula .

Monsoon Watch, our annual series chasing the Monsoon, will commence from 10th. April this year.
