Rain/snow generated by a prevailing western disturbance start to lift from Thursday but a successor would open a new weather front over Madhya Pradesh and parts of Central India from Friday/Saturday.

The prevailing disturbance over North Pakistan and adjoining Jammu & Kashmir may get a move to the East and out of the country, leading night-time mercury to fall over North-West and adjoining Central India over the next four to five days.

Rain, hail for Central India

This is because cooler westerly to north-westerly winds from across the international border would replace the warmer easterlies to south-easterlies commandeered by the ‘intense’ western disturbance till now.

An offspring cyclonic circulation from the erstwhile ‘intense’ disturbance has moved East-South-East while being embedded into a North-South trough. This would now anchor the flows from the successor disturbance expected in by Friday.

There is also an anticylonic circulation over East India (featuring clockwise winds) fanning into Central India, with its wind bands mopping up moisture from the Bay of Bengal into Central India.

Arrival of the fresh western disturbance would set up the stage for interaction of its westerlies with easterlies from the Bay triggering a lot of weather over Central India even as the North-West freezes. The India Met Department (IMD) said that the opposing winds would interact to trigger scattered to fairly widespread rainfall, isolated thunderstorms and hailstorm over parts of Central India and adjoining East and Peninsular India.

Wet climes for Peninsula

The wet weather would impact Madhya Pradesh, Uttar Pradesh, Vidarbha, and Chhattisgarh mainly on Thursday and Friday and parts of North Interior Karnataka, Telangana, and adjoining Coastal Andhra Pradesh around Sunday.

Meanwhile, towards the South, a low-pressure area over Equatorial Indian Ocean and adjoining central parts of the South Bay persisted, and is here for the longer haul, according to model forecasts.

It has been forced to stay put due to the feverish activity brewing over mainland India, and according to the weather tracker of the US Climate Prediction Centre, its wait might just have been extended for a few more days.

The ‘low’ may go on to become ‘well-marked’ or turn up even as a depression; but might weaken as it plots a track to the west-north-west towards North Sri Lanka or adjoining South-East Tamil Nadu.

Extended outlook for January 28 to 30 by the IMD has forecast isolated to scattered rain/snow likely over the hills of North-West India; isolated rainfall is likely over Andaman & Nicobar Islands; East and North-East India; as well as over South Peninsula.
