New Delhi, Jammu & Kashmir and Himachal Pradesh are expected to receive more snowfall and rain after the next 24 hours. Light rain would also occur in the National Capital Region Delhi along with Punjab, Haryana and west Uttar Pradesh during this period. With less sunshine, day temperatures may drop over these regions during the next 48 hours.
The Western Disturbance has moved away northeastwards. Another Western Disturbance over Pakistan and neighboring areas has moved to north Pakistan from Afghanistan during the last 24 hours and is expected to arrive by December 12 over Jammu & Kashmir.
So, northwest India may witness a brief pause in snowfall or rainfall activities during the next 24 hours but the expected movement of the Western Disturbance from Pakistan to Jammu & Kashmir during this period will again boost snowfall and rain in the region.
Snowfall activities in Jammu & Kashmir could continue for the next couple of days starting from December 13. One or two places in the state could even experience heavy snowfall of up to 300 mm during this period. Himachal Pradesh and Uttarakhand would also be receiving snowfall at one or two places and rain at a few places after December 12.
After a brief break on December 11, rain would also continue over Punjab, Haryana, Delhi and west Uttar Pradesh as the Western Disturbance affect would impact northwest plains. Shallow fog would again be witnessed during the morning hours in these areas during the next 48 to 72 hours.
The sky would remain cloudy to party cloudy to bring down the day temperatures further. The minimum temperature would rise due to a restriction on the cool and dry northwesterly winds over northwest India.
The moist southeasterly to easterly winds from the Bay of Bengal continue to have a brisk confrontation with dry and cool northwesterly winds over eastern India, thus forming a cyclonic circulation. East Madhya Pradesh, south Chhattisgarh, Orissa, Jharkhand and Gangetic West Bengal will receive rain at one or two places during the next 48 hours.
The cyclonic circulation close to Comorin and Maldives area would give rain at one or two places over southern parts of Tamil Nadu, Kerala and Lakshadweep during the next 24 hours. The trough of low pressure area over south Andaman Sea would continue to give rain over the Andaman & Nicobar Islands during the next 48 hours.
