IMD 's Ranchi Meteorological Centre issued a Nor'wester alert on Wednesday for isolated pockets of Jharkhand on March 12 and 13.

Deputy director of the Ranchi Met centre Abhishek Anand said excessive heating of land coupled with moisture incursion into the atmosphere would trigger Nor'wester activity, aided by a cyclonic circulation extending upto 0.9 km above mean sea level.

"We have issued an alert of thunderstorm, lightning and rain due to the impact of a Nor'wester in western and central parts of Jharkhand on Friday, March 12 and Saturday, March 13. Partly cloudy sky is expected to prevail for the next three to four days," he said .

The Met office forecast indicated clear sky from Sunday, March 14.

Met statistics revealed that the maximum reading has already touched 38 degree Celsius in Jamshedpur, Daltonganj and some pockets of north western Jharkhand. Most places across the state recorded readings that were four to five notches above normal. IMD has already predicted a harsh summer this year.

Met statistics revealed a highest maximum temperature of 38.4°C at Jamshedpur and the lowest minimum temperature of 18.6°C

at Bokaro.

Wednesday's satellite pictures suggested a trough extending upto 0.9km above mean sea level from Karnataka to

northeast Madhya Pradesh across central Maharashtra and northern Marathawada. The trough will assist in rainfall activity in Jharkhand.

Apart from that two fresh western disturbances in quick succession are likely to affect the western Himalayan region and adjoining plains of north west India from March 11 to March 13.
