Winter is an unusual time for India. Due its vast geographical diversity, the minimum temperatures during the season could vary from below zero degree Celsius temperatures to tropical 21°C. Usually the areas in North India witness single digit temperatures in early in November, but somehow that is not the case this time around.
At present, cold wave conditions are prevailing over most parts of Vidarbha and some parts of Marathwada and Madhya Maharashtra, even areas like Telangana, Chhattisgarh and interior Odisha and Jharkhand are experiencing cold wave condition.
Temperatures are below 5-7°C over many places in Vidarbha, for example Akola is presently at 11°C which is 7°C below normal. Amravati is 6°C below normal with a minimum of 11.4°C. Temperatures of many other places are hovering between 10-11°C.
All these areas are receiving cool northeasterly winds for last many days, that is why temperatures have fallen significantly. However other parts of Maharashtra such as Madhya Maharashtra are witnessing variability in wind direction.
This is why temperatures are fluctuating as the temperatures rise whenever winds change direction. Like if winds are blowing from northwest directions as these winds are warm from Arabian Sea. And when the wind directions changes to north-northeasterly, then the temperature falls.
Usually minimum temperatures in Vidarbha and Marathwada remain between 15°C to 17°C, but as of now the numbers are much lower than the minimum. It floats between 10°C -11°C. So we can say many areas Central India are much cooler than northern parts of country such as North Madhya Pradesh, West Uttar Pradesh and Delhi.
Cold Wave is declared whenever normal of minimum temperatures are 10°C or more and departure from normal is 4-5°C which is the current case in Central India.
