Sindh (Pakistan) Report:
We have mentioned the axis falling a bit southwards, and travelling thru central India, but the extreme western end of the axis, has also slid dpown and is over SE sindh, with the "gift" of an embedded UAC in the region.
The Western End of the Monsoon axis is today over the SE region of Sindh and adjoining Rajasthan. Though not very strong on surface level (998 mb), it has an embedded UAC over Rajasthan/Sindh region, "enriching" the region with moisture. Upper winds coming into Sindh are from the WD aloft, and these winds interacting with the UAC have caused much needed precipitation and thunder activity due to upper air interaction.
Our regular reader, Nasir, reports of 50 mms of rasin from a location 35 miles east of Sukkur. Other overnight rains were meagre and low, like Chhor 18 mms, Mithi 12 mms, Thata 9 mms and Sukkur 2 mms.
Thunderstorms are active in Chhor as of Wednesday evening.
We can expect the rains to move into Karachi tonight. Hyderabad can get some thundershowers tonight and maybe tomorrow afternoon. Sukkur can also expect thunder and rain tonight.
Though the rain amount may not be much, it will be a welcome releif as the rain amount thus far this season in these two cities has been 0 mms and 2 mms in Karachi.
We may even expect rain in Larkana on Thursday. Would expect the UAC to fizzle out by Thursday evening, with rains decreasing after Thursday. This spell in Sindh will last 2 days restricted to SE and than Southern Sindh region, with Central areas getting lesser rains. Gusty dust and thunderstorms likely in Larkana, Hyderabad and Sukkur Thursday evening.
