A Western Disturbance over Jammu & Kashmir is expected to interact with the western end of monsoon trough and move southward towards the northwest plains bringing rain over north Punjab adjoining Haryana, west Uttar Pradesh and Delhi during the next 24 to 48 hours.
However, this spell of rain will not have much impact on the temperatures in northwest plains as days will continue to be warm here. But Jammu & Kashmir, Himachal Pradesh and Uttarakhand may witness a drop in mercury level during the period.
Meanwhile, rain is expected to decrease over Bihar, Jharkhand and Gangetic West Bengal as the cyclonic circulation over north Bihar is weakening. Temperatures may also shoot up in the region.
Northeast will continue to receive most of the rain as eastern end of monsoon trough (region of intensified moist winds) remains in the foothills. This will continue to pull moisture from the Bay of Bengal to bring rain at many places in the region.
Central India will remain hot and dry for the next two days as there is very little chance of rain here. However, Chhattisgarh and Orissa may witness some rain due to a cyclonic circulation over Orissa coast.
The north-south trough in south Peninsula will keep the possibilities of rain alive over south interior Karnataka, Rayalaseema, Kerala and Tamil Nadu. There is also possibility that this trough may join with the cyclonic circulation over Orissa coast to bring showers along the east coast from Orissa to Tamil Nadu during the next two to three days.
There is a fresh surge of moist southwesterly winds along the West coast near Gujarat which may bring rain to Mumbai in next 24 to 48 hours.
