An incoming 'intense' western disturbance that had left Iran yesterday, has crossed East Afghanistan and North Pakistan and entered the western half of Jammu & Kashmir this morning.

India Met Department (IMD) expects an induced low-pressure area to form over West Rajasthan on Thursday even as a cyclonic circulation from a prevailing disturbance persists over South Haryana.

Interactive rain, hail

The westerly to north-westerly flows from the 'low' would likely interact with tropical easterlies kicked from the Bay of Bengal by a resident anticyclone for three days from today.

Under its influence, fairly widespread to widespread rain/snow with isolated hailstorms have been forecast over the Western Himalayan during this period.

Isolated heavy rain/snow is likely over Jammu & Kashmir and Himachal Pradesh tomorrow while scattered to fairly widespread rain/thundershowers and isolated hailstorms may lash North-West and Central India.

This is likely to pan out for three days from tomorrow, even as isolated heavy rains may prevail over the northern parts of Punjab, Haryana and Chandigarh.

The rainfall activity would shift towards East India from Friday and cause isolated to scattered rain/thundershowers over East India on Friday and Saturday.

Strong winds

Strong winds with speeds hitting 40 km/hr and gusting to 50 km/hr would prevail over the plains of North-West India and adjoining Central India on Thursday.

After the 'intense' westerly system and the 'low' weaken and pass over to East India and out of the country, a successor would rear its head over the international border across North-West India by Sunday.

While its influence would be felt over the hills on Sunday, it would bring to bear its grip over the plains of North-West India from the next day onwards (Monday).

Scattered to fairly widespread rain/snow has been forecast once again over the hills while scattered to fairly widespread rain/thundershowers are likely over North-East India.

Isolated rain/thundershowers has been forecast over the plains of North-West India, eastern parts of South Peninsular India and the Andaman & Nicobar Islands.

This could be attributed to the persisting moist easterly winds triggered by the location of the resident anticyclone, having been pushed to East India and adjoining Bay by successive strong western disturbances.
