‘Pakistan under severe heatwave since 10 days’
The cultural hub of the country came close in setting a new all time high temperature on May 23 as the highest temperature in the month of May occurred in 1990 (23 years ago) that was 47.4 °C according to NOAA. On May 23, the severe heatwave that has engulfed much of Pakistan since mid of May caused the temperature to rise at 47 °C thus coming close but not breaking the monthly temperature.
Lahore breaking day high records!
From May 18 till May 23, Lahore has witnessed new high temperature record for the day, following are recorded temperature;
- May 18 – 45 °C
- May 19 – 45 °C
- May 20 – 45 °C
- May 21 – 46 °C
- May 22 -46 °C
- May 23 – 47 °C
On May 23, Jacobabad (Sindh), Nawabshah (Sindh), Bhakkar (Punjab) and Nurpur Thal (Punjab) were at 50°C.
When will Lahoris be free?
Well, it is well known that load-shedding is intolerable in the city therefore the relief has to come from nature. From tomorrow there are chances that temperatures might start decreasing in the northern areas including Lahore. Tomorrow the mercury can be at 45 °C till 46 °C in Lahore. From May 24 night/May 25, a western trough ’08’ is coming to the northern areas that could bring drizzle/isolated showers with dust storms to those parts. Mostly cloudy with sudden dusty winds can occur in Lahore during the weekend with further drop in temperature.
The heatwave is under control for long!
On May 8, PWP predicted that a strong heatwave would affect Sindh from the coming week of May. On May 15, it gripped the entire country and gradually intensified on May 16/May 17. This heatwave will continue till the end of May as written in Monsoon III. Though some decrease of 2°C to 5°C from current situation could occur in the northern areas while slight decrease would occur in the central and southern parts. The heatwave would weaken by the first week of June.

Look at http://www.ecoseeds.com/5-23-2013-dust-cloud.png shows why it is so warm, without any rain, because the Pakistan-Arabia Dust Cloud has moved eastward over India to block the monsoon rains. Until the Dust Cloud moves aside, it may stay warm and dry for a while.
Northern areas are going to get a relief from tonight, western winds have started penetrating.
Babar bhai again this dust cloud issue is raising as mentioned by Mr. Craig……………………………….. how will it effect the western disturbances and monsoons in North eastern Punjab…….. ? im very concerned ….
Western trough is getting their way to northern areas. Some chances of pre-monsoon rain to in NE punjab in June.
What would cause pre-monsoon rains in Sindh ?
That second circulation can cause some activity, also some pre-monsoon thunderstorms could be over Gujarat that might affect SE Sindh.
Update on the Pakistan-Arabia Dust Cloud today, a massive amount of monsoon moisture at http://www.ssec.wisc.edu/data/comp/latest_cmoll.gif is backing up and being blocked by the Dust Cloud, and may cause torrential rains and floods in areas where the clouds are stalled, like Bangladesh and eastward. I hope that the weather services of Pakistan and India are keeping daily track of the Dust Cloud, because it has such an important influence on the floods and droughts of the region.
You can see the ability of the Dust Cloud to stop the monsoon clouds and cause floods today in Bangladesh, at http://pavelgospodinov.com/flooding-in-chittagong-bangladesh/
ISLAMABAD always gets pre monsoon shower.What will happen in isb and khaur.
Models do show some activity in there as well.
PRE-MONSOON WILL BE POSSIBLE THIS JUN IN KARACHI ?
Yes possible.
