TODAY'S WEATHER ACROSS AMERICA By Mark Vogan

Mid summer heat spreads upper 90s all the way to Nebraska today


TODAY'S WEATHER ACROSS UK & EUROPE By Mark Vogan

A cold upper and warm lower atmosphere over UK produced more t-storms and downpours, very warm air flowed up to northern Scandinavia, NW Russia


With the core of the dominant ridge now shifted eastwards and away from Britain thanks to the influence of the large upper low off Ireland, this aimed those balmy southerly winds from Spain up into central and even northern Norway, Sweden and Finland pumping 22-24C heat up there.

However, the Low Countries and central and eastern Europe remained warm and at least partly sunny once again. Western and even northwest Russia saw 27C today in a semi-permanent frozen region. This early season warmth would have been welcomed with open arms after a brutal winter here.

As for the UK, well highs did warm to 18C is many areas, slightly cooler further north into Scotland. However, south winds did bring mild air up, 20 to 21C was enjoyed across much of southern and central England again today, but with a much colder mid to upper level environment and this balmier lower level environment, this aided in bringing most areas of the UK heavy, intense showers which tended to come and go. Many produced thunder and lightning, including here around my area.

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

Heat Picking up....


With M1 now showing its back, we see the heating in the Northern plains taking shape.


Vagaries had predicted high temperatures from Monday, and this day showed, right away, a 45c at Ganganagar. The first 45c in India this year.

Various cities in the North are showing readings of 42-44c today.

In Pakistan, it Larkana and Mohen Jo Daro topping 48c today.(Recall, Mohen JO Daro touched 53c on May 26th 2010).

Night temperatures are getting hotter, with Kota showing a minimum of 33c on Monday morning. Coming days, nights, we shall see more minimums in the 30s!


Meanwhile, we see strong NW winds blowing across the plains of Northern India next few days, which may see the mercury rise further. New Delhi can gear up for 45c, and maybe some Rajasthan cities may head for 47c by Wednesday !Possibly this heat will be creeping into Vidharbha regions next 48 hrs.


A feeble M2 has crept in into Northern Kashmir. Not expected to have any significant effect on precipitation in the North. But, Next 2 days, we see M2 getting stretched due to strong NW winds,and forming a trough, almost at 998 mb, running along the Himalayan foothills. A trough will stretch from Northern U.P. into the plains of Nepal from Wednesday thru Friday, 11th-13th May.

Its eastern end is likely to attract moisture from the Bay and precipitate fairly good rains in the NE states, Sikkim and eastern Nepal regions these 3 days. Kathmandu, presently getting good showers, and will continue with these as the trough, extends eastwards from western areas of Nepal.

Next few days, I see a retreating MJO wave in the Northern Indian Ocean region. Covering the Arabian Sea and Bay, I see decreasing rainfall in the Bay, and the Bay Islands. In fact, very little rain is seen in the Bay Islands from 11th -15th May.


Retreating MJO and a eastwards pulling feeble (W.D.) trough will drive the upcoming rains eastwards into Myanmar, instead of increasing intensity over the Bay islands.


So, a delay in the SWM coming onto the Bay. Maybe after 16th now.
