A vigorous Atlantic storm spreads its leading clouds over the British Archipelago as of 1100 UTC Wednesday, April 17, 2013. At this time, the storm center as well as the strong winds were still located south and west of Ireland. Storm movement was quickly towards the northeast.
The second of two windstorms striking in quick succession will roll through Ireland and the U.K. Wednesday and Thursday.
Localized severe wind gusts near 60 mph (about 95 km/h) will whip Ireland, Wales, northern England and southern Scotland.
The storm center will brush northwestern Ireland before crossing northern Scotland on its way to the northeast Wednesday night and Thursday. Strongest winds will spread eastward and northward south of the storm center.
Beginning Wednesday over southern and western Ireland, the strongest winds will spread quickly to the rest of Ireland, including Northern Ireland, along with much of western and northern Great Britain. Strongest winds will then let up Thursday afternoon and evening as the parent storm heads for western Norway.
The storm's rainy aspect will be limited, as moderate to locally heavy rainfall will be restricted to parts of Ireland, Scotland and northwestern England.
High pressure will afford the region a break in the weather Friday through Saturday before unsettled weather returns Sunday or Monday.
The early week storm brought high winds to much of Ireland through southern and eastern Scotland as well as northern England. Tuesday, top gusts in Scotland were clocked at 57 knots (106 km/h) at Dundee and 56 knots (104 km/h) as Lossiemouth.
An odd side-note to the wind was the observation of blowing dust northern Scotland, both at Lossiemouth and at Inverness. Recent rainfall in much of Scotland has been unusually low, thereby making possible this otherwise very unlikely event.
The plum rains are known as "meiyu" in China, the "baiyu" or "tsuyu" in Japan, and the "jangma" in the Koreas. The heart of the plum rain season stretches from early June to mid-July, with a tendency to shift south to north across the affected area.
In the wake of the mid-June cloudbursts, most of Pakistan to northwestern India last week saw a return to dry, hot weather typical of the weeks leading up to the Monsoon onset. It was as if the Monsoon withdrew to its "normal" position for the latter half of June.
The 38.5 degree C (101 degrees F) reading Tuesday in Ajaccio, Corsica, may have been tops in Europe.
Monsoon Onset was June 13th, 2013, in Delhi, almost two weeks earlier than average. The June 15th onset at Karachi and Islamabad was more like three week ahead of schedule.
In Pakistan, hit-or-miss downpours missed the Sindh capital, Karachi. One did hit Pad Idan, where it left 60 mm of rain Wednesday. This was more than 20 times greater than the normal June rainfall.
It is still possible that this scenario is over wrought as to the intensity and spread of rain in Pakistan and northwestern India. However, it is the hunch of the present forecaster that some very unusual weather is going to unfold in the Subcontinent during the next week!
