Maximum temperatures recorded over large parts of northwest India during the 24 hours ending on Tuesday morning have ranged between 41 to 44 deg Celsius, an India Meteorological Department (IMD) update said.

Many parts of Punjab, Haryana, Rajasthan, Gujarat, Madhya Pradesh and Vidarbha and parts of Uttar Pradesh, Bihar, Chhattisgarh and Telangana were among those which witnessed these maxima, above normal by 2 to 3 deg Celsius.

The highest maximum temperature of 44.9 deg Celsius was recorded at Sri Ganganagar in Rajasthan.

But the IMD did not see significant change in maximum temperatures over the plains of northwest and adjoining central India until Friday.

This is also the period when a fresh but feeble mercury-killer western disturbance is expected to cross into the northwest and affect the hills and plains.

On Tuesday, however, a predecessor western disturbance over Jammu and Kashmir and neighbourhood was moving away eastwards.

A weather warning valid until Friday said that isolated dust storms or thunderstorms would break out over Rajasthan and west Uttar Pradesh.

Isolated thunder squalls would roll over east Uttar Pradesh, Jharkhand and West Bengal and Sikkim.

An extended forecast valid until Sunday said that isolated dust storms or thunderstorms could continue to hold sway over the plains of northwest India.

But fairly widespread rain or thundershowers may unfold over the Northeastern States and isolated over adjoining east India.

On Tuesday, the IMD traced an upper air cyclonic circulation to over west Uttar Pradesh and neighbourhood.

A trough from this system ran east-southeast towards Manipur across east Uttar Pradesh, Bihar, sub-Himalayan West Bengal, Sikkim and Bangladesh.

The trough would allow moisture-laden southeasterly winds to blow in from the Bay of Bengal and fuel the ongoing thunderstorm-driven turbulent weather in east and northeast India.

Satellite imagery on Tuesday afternoon showed the presence of convective (rain-causing) clouds over parts of east-central Bay of Bengal and Andaman Sea.
