Delhi woke up to an unusually cool and damp morning on March 21 as a fresh western disturbance reshaped weather conditions across large parts of India, bringing an unseasonal chill to the national capital and triggering a broader IMD rain warning for multiple states. The temperature in Delhi dropped to around 16 degrees Celsius in the morning, while cloud cover, mist and overnight rain combined to create conditions that felt far more like late winter than the third week of March. Forecast data for Saturday also showed Delhi staying relatively cool for the season, with a low near 16 degrees Celsius and a high around 27 degrees Celsius.
The unusual Delhi March chill comes as weather systems intensify across northwest, east and parts of central India. The Indian Meteorological Department-linked outlook cited in local reports pointed to an active western disturbance as the key driver behind the current pattern, with rain, thunderstorms, lightning and gusty winds affecting Delhi, Punjab, Haryana and Uttar Pradesh. Nearby NCR cities including Noida, Gurugram and Ghaziabad were also expected to see partly cloudy skies with chances of rain as the system moved across the region.
In northwest India, the western disturbance impact has been most visible in the form of cooler daytime temperatures, cloud buildup and scattered rain. Forecasts for Punjab and Haryana show mild daytime conditions for March 21, with highs around 25 to 28 degrees Celsius and cooler overnight lows near 14 degrees Celsius, reinforcing the broader sense of a temporary temperature dip across the plains. In the western Himalayan belt, Himachal Pradesh and Uttarakhand were expected to remain much cooler, with showers and lingering instability continuing into the weekend.
The weather story becomes more volatile in eastern India, where the India thunderstorm alert is tied less to a temperature dip and more to the risk of stronger storm activity. West Bengal was forecast to see heavy showers followed by a strong thunderstorm on March 21, while Jharkhand and Bihar were also expected to receive showers and thunderstorms during the day. A separate report on Kolkata said the city was under an orange alert for rainfall, lightning and gusty winds of 40 to 50 kilometres per hour through the weekend, underlining the seriousness of the situation in the east.
The picture is more mixed in central India. While the broad IMD-based narrative included Madhya Pradesh and Chhattisgarh among states seeing unstable weather, forecast data suggests conditions may vary sharply within these states. Some local reporting from Indore confirmed rain, thunder and strong winds had already pushed temperatures down noticeably, with officials expecting a gradual warming trend after the system moved eastward. That makes the present Delhi weather update part of a wider but uneven national pattern, where some regions are getting storm relief while others may return to heat quickly.
Experts tracking the March weather pattern say the bigger story is its variability. Analysis published today noted that western disturbances have been triggering rain and snowfall across northwest and northern India at a time when many regions would normally be transitioning more decisively toward summer. That helps explain why the Delhi March chill feels so unusual and why the IMD rain warning carries broader significance for agriculture, travel and local infrastructure. Storms at this time of year can improve air quality and temporarily cut heat, but they can also damage crops, reduce visibility and disrupt transport.
For Delhi residents, the immediate takeaway is that the cooler spell appears real but temporary. Forecasts show the capital warming again by Sunday, with the minimum rising to about 18 degrees Celsius and the maximum nearing 29 degrees Celsius. Even so, the sudden cool start to March 21 has turned the Delhi weather update into one of the most closely watched weather stories in the country, especially as thunderstorms continue to threaten states stretching from the northwestern plains to the eastern belt.
Delhi March chill linked to western disturbance impact
The rare cool spell in the capital is closely tied to the movement of an active western disturbance across northwest India. That western disturbance impact has lowered temperatures, increased cloud cover and triggered rain in Delhi and surrounding states, making the morning feel unusually cold for late March.
IMD rain warning expands India thunderstorm alert
The broader IMD rain warning goes beyond Delhi, with reports and forecasts pointing to thunderstorms, lightning and gusty winds in eastern states such as West Bengal, Jharkhand and Bihar. This wider India thunderstorm alert suggests that the current weather shift is not isolated, but part of a larger national pattern driven by multiple active systems.
