F-1, the system will not move into the Northern India hill states as expected..but, will cover most Pakistan regions, Central and coastal Pakistan.

On Schedule. Many places in Pakistan received the F-1 rains on Saturday. While rains were recorded from Parachinar, Quetta, Dal Bandin and Islamabad, rains are moving eastwards along the Sindh coast. Karachi shouls see light showers on Saturday night...
Sunday shown below: though there is a "defiant" high pressure at 850 mb over Northern India. A very favourable 500 mb wind flow may help. i do not think it should create any hindrance to F-1 for moving into India on Sunday/Monday...F-1 moving into NW India and the hill States...with clouds in Delhi with light rain chances in some parts at night...
3rd Feb Sunday: The system now moves thru entire Pakistan and into NW India. F-1 moves into plains of Pakistan and Indian Punjab, Haryana and cloudy over Delhi NCR. Light rains over Delhi NCR on Sunday night, with SE winds gaining speed..
