The convergence of moist southwesterly winds in the lower levels aided by favourable upper-level wind pattern is likely to cause scattered to fairly widespread rain/thundershowers over Northeast India (Arunachal Pradesh, Assam & Meghalaya and Nagaland, Manipur, Mizoram & Tripura) and Eastern states (West Bengal, Sikkim, Odisha, Jharkhand and Bihar) during next 4 days, said the weather forecast report in its morning bulletin.
Thunder Squalls & hailstorms likely over these regions
Thunderstorms accompanied with lightning and occasional thunder squalls (wind speed 50-60 kmph and more), hailstorms at isolated places are also likely over these regions during this period with peak activities on 12 and 13 May when heavy rainfall also likely at isolated places over West Bengal & Sikkim and adj North-Eastern states.
Scattered rain/thundershowers over Western Himalayan Region and Plains of Northwest India
The Western Disturbance is likely to move further northeastwards and interact with the low-level circulation and easterlies over northwestern parts of India causing an increase of moisture incursion in the region. These features are likely to cause isolated to scattered rain/thundershowers over Western Himalayan Region and plains of northwest India mainly during 10th to 13th May 2020 with peak activities on 10 May. Thunderstorms accompanied with lightning, hail and gusty winds (30-40 kmph) at isolated places also likely over these regions during the same period.
Scattered rain/Thundershowers likely over Central & South Peninsular India
Due to trough/wind discontinuity, isolated to scattered rain/thundershowers very likely over central & south peninsular India during next 4 days. Thunderstorms accompanied with lightning, hail and gusty winds (30-40 kmph) at isolated places also likely over these regions during same period. Heavy rainfall also likely at isolated places over Kerala and Mahe and south Karnataka on 12th &13th May.
Maximum Temperatures are likely to remain between 41-44°C over some parts of Rajasthan, north Gujarat state, north Madhya Maharashtra, Marathwada, Telangana, and North Interior Karnataka during next 1-2 days and decrease thereafter for subsequent 2 days due to likely rain/thunderstorm activities over these areas.
As per yesterday's reports, maximum temperatures were appreciably above normal (3.1°C to 5.0°C) at many places over Nagaland, Manipur, Mizoram & Tripura; at a few places over Arunachal Pradesh and Assam & Meghalaya; at isolated places over Gangetic West Bengal while maximum temperature were appreciably above normal (3.1°C to 5.0°C) at isolated places over East Rajasthan and West Madhya Pradesh.
