TODAY'S WEATHER ACROSS AMERICA By Mark Vogan

Another Day of Severe Weather, Flooding Rains etc etc

A very blocked up pattern has slowed the storm system causing all the bother across the Heartland because of another, larger ocean storm system off the East Coast. This system off the coast not going anywhere means that the front associated with the storm in the heart of the country is going to basically crawl one state at a time eastwards over the next 5-7 days and this will mean increased flooding risk across the already flooded areas as well as much of the East. 




TODAY'S WEATHER ACROSS UK & EUROPE By Mark Vogan

UK returns to normal temperatures but we've went back in time, we're now enduring 'April Showers' in May

It would appear that with a pattern more suitable for April with fast and often furious showers one minute and sunshine the next, the pattern has flipped opposite. We're experiencing April in May and May in April.

The low continues to do it's work as it slowly treks northeastward hurling in frequent showers which as they cross the cool ocean waters and then warmer land, we're seeing some enhancement to these showers these fast moving clouds get ejected upwards into the colder reaches, creating added instability which results in some thunder and lightning and hefty hailshowers.

The overall pattern is such that we see faster movement the further north in the UK you are. The winds blow quicker the closer to the centre of the circulation and thus, winds are lighter and showers perhaps longer lasting when over you and the sun shines longer also in between those showers in such regions as the southwest and southeast of England.

Southern Europe will remains mostly sunny and warm over the next 48 hours but the NW mainland will see cloudier skies and cooler temps as a result with both London and Paris only rising to the upper teens tomorrow and mid teens by Saturday.

WEATHER TALK
By Mark Vogan

Could last May's record 53.7C (128.3F) recorded at Mohenjo-daro, Pakistan be reached again as fierce heat builds over same region?


Overall, across the Thar Desert region which takes in the notably scorching Sindh province of Pakistan and India, it has been a relatively cool April with many cities recording 5 to 7C below normal, the exact opposite to around the same period last year where temperatures averaged 5-7C above normal and high pressure was persistently stronger than normal and a drought was more severe than normal across an already barren, arid part of the world.

During what seemed like an endless heat wave throughout the Indian sub-continent stretching from February right up until the massive monsoon floods in early June, temperatures on several days cracked the 50C mark with a remarkable 53.7C high recorded at Mohenjo-daro, Sindh, Pakistan on May 26. This was not only an all-time record high for Pakistan but it was also the highest reliable high temperature recorded on the vast continent of Asia as a whole.

The combination of extreme drought conditions in an already dry environment, time of year and where the strongest pressures in the Northern Hemisphere are typically positioned during the April-May period all played a key role in producing such a high reading.

Highest readings likely to top 50C in coming days

Up until now, the hottest temperatures have been averaging around 44 to 46C in the typical hot spots such as Jacobabad, Larkana and Nawabshah to name 3 but the surrounding region and throughout Pakistan and India, highs have been topping out at around 34-40C which for this time of year isn't all that hot.

Recent days has seen the hot spots soar toward 50C with a peak both today and yesterday of 48C, the highest so far. My fellow blogger and author of Vagaries of the Weather, Rajesh Kapadia of Mumbai, India has stated, saying that by the region normally sees 50C (122F) by mid to late May.

Temperatures reach record high in Pakistan

From Wikipedia

The weather extremes in Pakistan include high and low temperatures, heaviest rainfall and flooding. The highest temperature ever recorded in Pakistan is 53.5 °C (128.3 °F) which was recorded in Mohenjo-daro, Sindh on 26 May 2010. It was not only the hottest temperature ever recorded in Pakistan but also the hottest reliably measured temperature ever recorded on the continent of Asia. and the fourth highest temperature ever recorded on earth. The highest rainfall of 620 millimetres (24 in) was recorded in Islamabad during 24 hours on 24 July 2001. The record-breaking rain fell in just 10 hours. It was the heaviest rainfall in Islamabad in the previous 100 years.


Record-breaking 2010 summer heat wave


The hottest temperature ever recorded in Asia and the fourth highest temperature ever recorded in the world was in Mohenjo-daro, Sindh at 53.5 °C (128.3 °F) on May 26, 2010. Twelve cities in Pakistan saw temperatures above 50 °C (122 °F) during the extreme heatwave of summer 2010, which lasted from May 24 to May 31, 2010. On May 27, temperatures higher than 45 °C (113 °F) hit areas across Pakistan and at least 18 people died as a result. Also, during the extreme heatwave season, 11 cities saw their highest ever recorded temperatures of 50 °C (122 °F) or above, and five cities saw temperatures of 53 °C (127 °F). 11 cities also saw extremes of more than 45 °C (113 °F) but below 50 °C (122 °F). The previous record for Pakistan and for Asia was on June 12, 1919 at 52.7°C (127°F) in Sindh.
