At present, Southwest Monsoon is in its withdrawal phase and has already started withdrawing from many parts of the country. However, most parts of the country excluding a few are still witnessing good rains.
Southwest Monsoon has already withdrawn from entire Jammu and Kashmir, Punjab, most parts of Himachal Pradesh, West Rajasthan and some parts of Haryana. Because of this, most of these areas are experiencing an above normal temperatures while some are settling at a temperature below their normal range.
Minimum temperatures are appreciably above normal over Punjab, Jammu and Kashmir, Himachal Pradesh, Uttarakhand, Uttar Pradesh, East Rajasthan, Madhya Pradesh, Gujarat, West Bengal and Sikkim.
Reason for these above normal temperatures over the eastern and northern parts of the country including the hilly areas can be attributed to the moist easterly winds blowing from Bay of Bengal. These winds are comparatively warmer in nature and hence minimums are rising.
Moreover, humid winds from the Arabian Sea are affecting the weather conditions prevailing over West Rajasthan and Gujarat. Thence, parts of both these states are witnessing an above normal temperatures during early morning and night.
Now, the winds are expected to converse and start blowing from northwest direction in next 2-3 days. Therefore, temperatures over most parts of northern plains including Punjab, Haryana, Delhi and Rajasthan including West Uttar Pradesh are expected to fall. As the humidity level will start decreasing significantly, dry and cool northwesterly winds will continue to blow.
Most of the regions are also witnessing an above normal maximum temperatures. Places like Assam, Meghalaya, Bihar, Jharkhand, Gangetic West Bengal, East Uttar Pradesh, East Madhya Pradesh, Andhra Pradesh, coastal Karnataka and Kerala are all witnessing a 3-5 degrees above normal day’s temperature.
Reason for these high day temperatures can be associated with prevailing dry weather conditions along with isolated showers over all these areas. In the absence of rain and cloud cover, these temperatures are continuously witnessing a rise.
Areas where maximum temperatures are below normal are the region which are presently witnessing rains. These areas include Gujarat, West Rajasthan, Madhya Maharashtra, southeast Rajasthan and Konkan and Goa.
Now, it is expected that rain activities over many parts of Rajasthan will start reducing significantly. Therefore, the day’s temperatures will gradually scale up over the area.
As per Skymet Weather, October is considered as a transition phase from warm weather to commencement of winters. In a week time, entire northwestern plains will start experiencing relatively cooler mornings and nights and it will mark the beginning of winter season. By the latter half of the month, light rains will commence as well.
