The minimum temperatures are likely to rise by 2 to 3°C in northwest India as a Western Disturbance is expected to make its presence felt by cutting off the northwesterly dry and cool winds. It would also bring clouds in the region, which will lead to a drop in daytime temperatures as sunshine may reduce during the next 24 to 48 hours.
The Western Disturbance is currently placed over Pakistan and will arrive tomorrow over Jammu & Kashmir. This would bring snowfall and rain in the northwest hills and the plains. Heavy snowfall or rain could occur at one or two places over Jammu & Kashmir. Snowfall activities would increase over this region after 24 hours. Snowfall or rain is also likely at one or two places over Himachal Pradesh and Uttarakhand during the next 24 to 48 hours.
The plains in the region over Punjab, Haryana, Delhi and west Uttar Pradesh could also experience thunder activities along with light rain at a few places during the next 48 hours. Moisture in the winds could also create shallow fog during the morning hours over these places.
The weather system(WD) would also push some energy towards Indo-Gangetic plains to raise the minimum temperatures. The region is witnessing below normal minimum temperatures for the last fortnight. However, the prevailing northerly cool and dry winds over eastern parts of the country over east Madhya Pradesh, Chhattisgarh, Jharkhand Orissa and West Bengal would mix with the easterly winds from the Bay of Bengal. This mix up would lead to rain in this region during the next 48 hours.
The effect of Western Disturbance over northwestern parts of the country would continue as this weather system is being followed up by two other Western Disturbances slated to affect the region till December 16.
A trough of low pressure area extends from southeast Arabian Sea to east-central Arabian Sea. Under its influence, rain would occur at a few places over Lakshadweep islands and at one or two places over southern parts of Tamil Nadu and Kerala during the next 24 hours.
