All India weather forecast till March 24, 2024:

Pre-monsoon rains batter east and north-east India.

Weak Kalbaishakhi events were triggered last week, starting Friday, in parts of east India and are all set to intensify in the coming week. A trough as a confluence zone of dry north-west winds and moist south-easterly is present over Odisha, West Bengal, and Jharkhand. This is creating high instability in the lower and mid-layers of the atmosphere. As a result, the upcoming week, starting March 18 until March 23, will host widespread norwesters in east India.

Morning hours will be mainly dry, but thunder clouds will start developing in the afternoon hour and peak during late evening and night.

Widespread moderate to heavy rain, hailstorms, lightning strikes, and thunder are expected across West Bengal, Jharkhand, Odisha, Chhattisgarh, Telangana, Andhra Pradesh, Vidarbha, east Madhya Pradesh, and south Bihar for the next four to five days.

This prolonged spell of rain will also ensure a drop in daytime temperatures and restrict the entry of summers in the eastern parts of the country for another week, as temperature anomalies will be 4 to 5°C below normal.

The climate pattern this year seems to be pretty normal; south-east winds will start reaching north-east states over the upcoming week. This will ensure on time the start of pre-monsoon showers in Meghalaya, Mizoram, Manipur, Nagaland, Tripura, Assam, and Arunachal Pradesh. The rains during the upcoming week will remain mainly light to moderate in nature and restricted to the second half of the day; hence, afternoons will remain warm and humid.

Southern parts of India would continue to bake under hot weather as pre-monsoon rains have yet to set in. Normally, light to moderate rains start in Kerala and the south interiors of Karnataka, including Bangalore, during the second half of March; however, this time it would continue to stay relatively drier, resulting in abnormally high temperatures.

From March 18 to March 22, moderate to heavy rains and thunderstorms will occur in parts of Telangana and Andhra Pradesh. This would bring significant relief to the states from building heat; day temperatures will fall by at least 2 to 3°C. No major change is planned in Tamil Nadu, Kerala, Karnataka, and Goa, which will continue to experience dry and hot weather till March 24th, 2024.

Spring will fade away steadily in north India as weather models hint at a rise in temperature over the upcoming week in the absence of any major western disturbance.

One of the major factors controlling the rise in temperatures won’t be approaching northern India for the next week or two. As a result, north-west winds will start becoming warmer. Both minimum and maximum temperatures are predicted to increase by 3–4 °C during March 19–24 across Rajasthan, Haryana, Punjab, Delhi NCR, Uttar Pradesh, and Bihar.

In the Himalayas, winters will still prevail, as nights are likely to stay chilly under clear skies. A weak western disturbance around March 21 will bring a spell of fresh light snowfall over the upper reaches. The strength of the upcoming western disturbance will remain feeble for the rest of March, and one can expect the onset of summers at least in Rajasthan towards the end of March.
