New Delhi, Snowfall and rain are expected over Jammu & Kashmir and Himachal Pradesh over the next 24 to 36 hours. Northwesterly winds would continue over Gangetic plains during the next 24 hours. Subdued rain is likely to continue in the southern most parts of Peninsular India and rain would reduce over northeastern states of Assam and Arunachal Pradesh during this period.
The Western Disturbance has arrived over Jammu & Kashmir and is expected to affect the region during the next two days. The weather system is weak and unlikely to bring much of a rain or snowfall yet one or two places in Jammu & Kashmir and Himachal (in the higher altitudes) could receive snow or rain.
The weather system would stop the flow of northerly winds over the northwest region and this could raise the temperatures further. The region is already experiencing above normal maximum temperatures by 2 to 3 degrees. The sky will be cloudy to party cloudy over the region. Hills will be mainly cloudy. Another Western Disturbance is expected from December 11 over Jammu & Kashmir.
But the northerlies would continue in the Gangetic plains as the winds associated with the latest Western Disturbance are blowing much higher than the northwest plains. The night temperature would remain below normal by 1 to 2 °C in some parts of the Gangetic plains during the next 24 to 48 hours.
In the south, the cyclonic circulation over Comorin area in Kerala has turned insignificant, so rain would further reduce over Kerala along with Tamil Nadu, Rain is likely at a few places over south Tamil Nadu and south Kerala and at one or two places over rest of Tamil Nadu and Kerala.
The cyclonic circulation over the northeastern states has moved out in an eastward direction. This will reduce rain over the region. The weather over rest parts of country is dry.
