Outlook for the coming Weekend, Friday,18th, Saturday19th and Sunday 20th April;

Friday: A-4 will be precipitating in the Northern Pakistan areas of Punjab and Upper Sindh and parts of South Sindh. Many Central Sindh cities like Nawabshah, Sukkur and Hyderabad are likely to get rains. 

In India also, the WD will precipitate in Kashmir, HP, Uttarakhand, Punjab, Haryana and some severe storms in Rajasthan and North MP.
The higher reaches of the Hill states are likely to get snow. Heavier showers in Western Nepal.
That means, continuing below normal day temperatures in the North.
A trough, and a semi formed LWD will get thunder showers to Southern Maharashtra and interior Karnataka. 
Belgaum can get the evening thunder shower.

Bangalore too can possibly get the long waited thunder shower on Friday.

Saturday:
A-4 moves east, and keeps the Sindh dry. Sporadic showers continue in Pak Punjab.
Northern India get another day of rains, which decrease by Saturday night. Rains in Punjab, Haryana and Northern Rajasthan plains will continue for another day.
Raipur can get another Thunder shower on Saturday/Sunday.
A-4 weakens and withdraws from the region. Rains almost cease in the North, bringing out the sun and heat from Monday.

Southwards, Thunder showers will lash Southern Maharashtra and Marathwada. The "line " of Thunde cells developing will be Southwards from Southern Maharashtra into adjoining N.I. Karataka, which too will get thunder showers. But rains decrease in S.I..Karnataka.

As the WD disintegrates , Kathmandu can get light showers on Saturday. Otherwise we see the days pleasant around 30c, heating up suddenly from Sunday.
Sunday:

But its Maharshtra special for Sunday,with the entire state barring Konkan poised to get thunder showers.Thunder showers cooling Nagpur and Aurangabad on Sunday.
