On Weather & Climate Through the Eyes of Mark Vogan

Very Late Season Snow Aims for Washington DC tonight, Philadelphia northwards to NYC and Boston stays clear but cold!

-By Mark Vogan

TEMPS AT ONE POINT THIS MORNING ACROSS NORTHEAST
Saranac Lake, NY 0 degrees, Mt Pocono, Pa 14 degrees, Toms River, NJ 21 degrees, Millville, NJ 22 degrees, Asbury Park, NJ 24 degrees, Philadelphia, Pa 27 degrees, New York, NY 26 degrees.

Whilst the cities of Philadelphia, New York and particularly their suburbs escape snow this evening it will be all eyes further south tonight. Perhaps from around Downtown Baltimore or it's south suburbs should folks be on the lookout to at least see it snow if not stick and accummulate to perhaps a coasting to as much as 2". Further south and Metro DC may see 1-3" I think whilst southwest suburbs (perhaps Arlington, VA) may see 2-4" amounts through tonight along with breezy conditions which could make travel dicy.



Whilst it's all eyes on a far reaching snow band stretching all the way from Missouri, Kentucky, West Virginia all the way east to the Delmarva tonight, to the south, it's heavy, wind driven rains that could well help ease drought conditions across Georgia but some of these cells may transform into strong thunderstorms with embedded severe weather.

North of the storm, and there will likely be a sharp cutoff from cloudiness, from Philadelphia north through Trenton, Newark, New York all the way to Boston and up into Maine. Like this morning, here, temperatures will fall sharp and already are. The major cities from Philly to Boston will drop into the mid-20s with Boston perhaps aiming for 20 degrees by morning. Outlying suburbs of Philly and New York may even get into the low 20s withhilly terrain of NW Jersey perhaps hitting the 10s. Most places this morning fell well into the 20s with 21 degrees at Toms River, on the central Jersey Shore. Asbury Park was at 24 degrees, Philadelphia 27, Central Park, NYC 26 and all these sites saw biting wind chills at 20 degrees or colder. Places like Philadelphia may see a little more cloud as it is closer to the storm system, thus not getting as cold as it did this morning.

WEATHER TALK
By Mark Vogan

Although clocks move forward by one hour at 2am Sunday morning, why is it then classified 'official UK summertime'?

It's bad enough that you loose an hour out of your life by springing forward once but, unfortunately, during my recent visit to the US, I happened to time my holiday during the weekend in which the clocks went forward. Tonight, it's the UK's turn and my turn TWICE now... not a happy chappy to be honest, however it could be worse I guess, I could have work to get up for tomorrow and thankfully I don't.


Our clocks now changing means US Eastern Daylight Time which once changed two weeks ago put us here in the UK only 4 hours ahead of Miami, DC and New York but as of 2am Sunday morning it returns to the traditional 5 hour gap.


Ok, I better get to the point of all this. For the UK, once we 'spring forward', that is 'apparently' official British summertime. So, even if we get snow tomorrow and that isn't incredibly difficult to do here in late March, that would mean it's snowing in summer. Surely, summer is a season that congers up images of sun, sand, sea and most importently HEAT, am I right?? So, who in their right mind decided that when we change our clocks forward, hey, we might as well call it 'summer'?!


In the USA, once the clocks change, they change and nothing else, then, on the following Monday at around 7.21pm ET, some 8 days after the clocks sprung forward do they declare 'official springtime', makes sense right?, and yes that's not a typo, it's spring I wrote.


Meteorologically, summer commences in the USA as of June 1st, but actual summer doesn't start until June 21st, which I do agree is pretty late considering that May can see hot weather and summer conditions. However I agree with the June 1st start to summer and believe that our change of clocks declaring 'official British summertime' is simply rediculous. There is too much winter weather potential well into April here, never mind we rarely warm up proper until at least late April.


To round up, I believe we here in the UK should go more by America on this one, afterall whilst it's very possible to see late March snow in "summer" here, there have been a few April heatwaves in recent times across the Eastern US which produced 90s all the way to Boston and that's in spring there and hotter at times during during June, July and August!!!

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

The Bay of Bengal is starting its seasonal buzz. B1 is born, and its "baby name" is 93B.


Pleas glance thru Vagaries' Forecast for the weekend, put up on 23rd, before reading this post ! -:)


93B has formed as Vagaries estimated, on Saturday, 26th, and is presently just "young" at 1008 mb. It is centred at 9.1N and 93.7E. Expected to deepen, and attain a "well marked low" status by Monday, at 1004 mb. In the next couple of days, rainfall will be heavy and tropical in the Bay Islands.


But, Vagaries maintains, the system is not going to effect the Indian Coast, and may just fizzle out, by reaching 1002 mb at the peak, by mid next week. What will be seen is a big spread of clouds, that will "infalte " by Tuesday, covering the entire Bay.


When a system deepens, and gets stronger, the clouds are concised within a limited radius, and stick together. But when a system weakens, the clouding spreads over a larger area.


M3, also which has kept its Saturday schedule, is precipitating over Northern Pakistan today, Saturday. regions in India , the hill states, have also become cloudy, and seeing snow in the Northern most regions of the Himalayas. Like mentioned, M3 will slide into Nepal by Sunday/Monday, and give pockets of precipitation, including Kathmandu.


For the rest of the regions, Pakistan and Nepal, the weekend forecast mentioned holds good. Pakistan and India, both were contained to a maximum of 40c today.


Since vagaries forecast is up to Sunday, next 4 days forecast will be put up on Sunday night.


The clouds anticipitated in central India, including Vidharbh, featured in Vagaries' forecast map on the 23rd. This as explained, is a result of the line of wind discontinuity across this region.


Now, the line still persists, (though this was not anticipated. We thought it to survive for 2/3 days), and quote from a IMD report of 26th. "The trough/wind discontinuity at 0.9 km a.s.l. now runs from Bihar to south Tamil Nadu across Jharkhand, Chattisgarh, Vidarbha, Telangana, Rayalaseema and south interior Karnataka.''


Please make a point of clicking here to see Rajesh's blog who is in partnership with Weather & Climate Through the Eyes of MV. It's very informative, scoping not only the Radar across India, but the Sub-Continent as well as abroad. The best of it is, it's all from from a locals perspective!
