The approaching Western Disturbance is expected to raise the minimum temperatures over northwestern plains by cutting of the northwesterly winds during the next 24 hours. Drop in the humidity level as well as rising minimum temperature way above dew point would not let fog get denser. These areas would have moderate fog during this period.
The Western Disturbance is currently positioned over north Pakistan, near Jammu & Kashmir. It is moving east-northeastwards and would make an appearance by tomorrow in the region. Under its influence, rain or snowfall would commence over higher ridges of Jammu & Kashmir.
Snowfall or rainfall would increase after the next 24 hours and can spread to Himachal Pradesh and Uttarakhand. Jammu and Kashmir will have snowfall or rain at one or two places. Few places in Jammu & Kashmir will receive heavy snowfall during the next 24 hours. In the plains, Punjab and Haryana could receive rain or thunder showers at one or two places during the next 24 to 48 hours.
Fall in the night temperatures by 2 to 3 degrees is expected over Indo-Gangetic plains as northwesterly to northerly cooler winds would have an affect during the next 48 hours. So, Indo Gangectic plains would see dense fog and severe cold wave like conditions during the next two days as cool winds are mixing up with moist easterly winds.
In the southwest Bay of Bengal, an easterly wave would bring rainfall at a few places in coastal Tamil Nadu. Interior Tamil Nadu, Kerala and Lakshadweep would receive rain at one or two places during the next 24 hours. More places will witness rain in these places thereafter.
