Rain is likely to return to Delhi by Saturday. Other parts of the northwest region could see a surge in wet sessions from 15 February onwards. Also exopected are hailstorms in the plains and snowfall in Himachal Pradesh and Uttarakhand. The rainfall will shift east gradually thereafter.
A western disturbance is expected to move over the western Himalayan region from 15 February, which could again unleash rainfall and snow over Jammu and Kashmir, Himachal Pradesh, Uttarakhand and the plains of Punjab, Haryana, northern Rajasthan and western Uttar Pradesh for the next three days. The change in Delhi weather will be a consequence of this western disturbance.
The amount of snow and rain will depend on the strength of the weather system, basically a low pressure trough that travels east-northeastwards from its place of origin (the Mediterranean Sea and the Atlantic Ocean). The weather in Delhi during winter usually becomes cooler as the western disturbance leaves the area.
Till then, Delhi along with other areas in northwest plains will see a rise in night temperatures by 2-3 degrees during the next two days. Meanwhile, day temperatures are above normal in the region as well as in central India. Night temperatures are increasing under the influence of the present western disturbance over Jammu and Kashmir.
The ongoing western disturbance is weak and will not bring significant rain compared what we saw at the start of last week. However, higher altitudes will see an increase in snowfall and rain during the next 72 hours.
Madhya Pradesh and Maharashtra are witnessing a confrontation of southeasterly and northerly to northwesterly winds. This will continue to give rain at one or two places during the next two days.
The southern parts of Tamil Nadu, Kerala and Lakshadweep will also continue to receive rain during the next two days. The southern peninsular region has two low pressure areas on both its east and west flanks. The southwest Bay of Bengal has a low pressure trough near south Tamil Nadu and Kerala while Lakshadweep has one that runs up to the south Maharashtra coast.
