Westerlies may spark thunderstorm season

India Meteorological Department (IMD) has predicted the possibility of isolated thunderstorms or dust storms over the vast plains of Haryana, Delhi, Rajasthan, Uttar Pradesh and Bihar during the rest of the weekend.

An evening bulletin on Thursday said that isolated rainfall occurred over north Rajasthan, Haryana, Madhya Pradesh and Vidarbha in northwest and central India.

Towards the east, rainfall has also been reported from Assam, Meghalaya, Arunachal Pradesh from presiding atmospheric features.

In the south, Kerala and Andaman and Nicobar Islands benefited as an easterly wave persisted over southeast Bay of Bengal.

A weather-making upper air cyclonic circulation has showed itself up over Haryana and neighbourhood.

To the immediate east, a north to south upper air trough ran down from Bihar to south Tamil Nadu across Chhattisgarh and Andhra Pradesh.

This churn in the atmosphere could be the prelude to the advent of the seasonally violent weather, called locally as “andhis,” triggered when cooler and moisture-laden northwesterlies force themselves downstream over the heated-up plains to the east-southeast.

At the far end to the southeast, they could spark the flare-up of severe thunderstorms, known locally as Nor'westers, given the direction from where they originate, or Kal Baisakhi, for the damage to life and property they portend.

Localised cyclonic circulations in the lower levels, one of which lingers over the Assam and Meghalaya region, mop up incremental moisture from the Bay of Bengal to add to the strength and intensity of the storms.

These forecasts need to be read in the context of expected arrival of a fresh western disturbance over the next couple of days.

The IMD has maintained the forecast for a low-pressure area springing up as the easterly wave peaks in activity.

Maximum temperatures changed little over the country during the day on Wednesday.

MERCURY TRENDS

They were above normal by 2 to 5° C over parts of western Himalayan region, Punjab, Haryana and Delhi and by 2 to 3 deg Celsius over parts of west Uttar Pradesh and central, east and northeast India.

The highest maximum temperature of 41.5 deg Celsius was recorded, for the second consecutive day, at Gulbarga in Karnataka.

Satellite image early on Thursday morning revealed the presence of convective clouds over parts of south Bay of Bengal and Andaman Sea.

Forecast valid until Sunday said that fairly widespread rain or thundershowers would continue over the Andaman and Nicobar Islands

Fresh ‘active’ westerly keeps date with hills of northwest India

Upper reaches of northernmost and northwest Kashmir and adjoining slopes have all been ‘whitened up’ by a fresh ‘active’ western disturbance keeping date with the forecasts early this (Tuesday) morning.

Associated clouding and moisture has enveloped Uttarakhand, Himachal Pradesh, Punjab, Haryana, Delhi and parts of west Uttar Pradesh even as a feed streaked in from north Gujarat and across adjoining southeast Rajasthan.

The clouding has brought down the maximum temperatures to below normal by 3 to 5 deg Celsius over many parts of Rajasthan, Uttar Pradesh, Madhya Pradesh and Orissa, Chhattisgarh and Jharkhand towards the east.

An India Meteorological Department (IMD) update said on Tuesday morning that the active western disturbance would affect the western Himalayan region from today (Tuesday) onwards and the plains of northwest India mainly from Thursday to Saturday.

A weather warning valid for Friday said that isolated thunder squalls or hailstorms may occur over the plains of northwest India. Satellite imagery on Tuesday morning showed the presence of convective (rain-bearing) clouds over parts of Jammu and Kashmir, around the peninsular tip and south Bay of Bengal.

A short-term outlook valid until Friday for specific regions said that scattered rain or snowfall would occur over Jammu and Kashmir today and increase thereafter. Isolated rain or snowfall would occur over Himachal Pradesh and Uttarakhand from today and increase thereafter.

Over the plains, isolated rain or thundershowers has been forecast for Punjab and west Rajasthan on Thursday, with the rain belt expected to scale up thereafter and extend to many parts of northwest India.

In the south, isolated rain or thundershowers would occur over Tamil Nadu and Kerala until Wednesday morning and increase thereafter.

East and S-E India :: Thundershowers ahead for rest of the week

Global forecasts favour a situation where northwest India, east-central India, the east coast and the southern peninsula staying wet through the week to sign off February.

The European Centre for Medium-Range Weather Forecasts finds scope for yet another “active” western disturbance around February 26.

In the east and south, residual moisture in east India and accretions fanned by southeasterlies from the Bay of Bengal could feed thunderstorms during this week.

THUNDERSHOWER REGIME

The US National Centres for Environmental Prediction is also in agreement with this outlook.

Meanwhile, an India Meteorological Department (IMD) update said that northwest India and east and east-central India have already been brought under the influence of a sustaining string of thundershowers. Thundershowers enveloped the plains of northwest and even marched into east and east-central India with localised heavy rainfall being reported from isolated places in the region during the 24 hours ending Monday evening.

‘ACTIVE' WESTERLY

Scattered rain or snowfall occurred over Jammu and Kashmir and Himachal Pradesh and isolated over Uttarakhand ahead of the arrival of an “active” western disturbance from across the border on Tuesday.

Widespread rainfall has been reported from Orissa while it was fairly widespread over Haryana, east Madhya Pradesh, Jharkhand and Chhattisgarh.

It was scattered over Punjab, east Rajasthan, Gangetic West Bengal and Vidarbha.

The fresh “active” western disturbance would affect western Himalayan region from Tuesday onwards and the plains of northwest India mainly from Wednesday to Saturday. A weather warning issued by the IMD said that isolated thunder squalls or hailstorms may occur over Orissa, Chhattisgarh, Gangetic West Bengal, Jharkhand and north Andhra Pradesh until Tuesday evening.

SOUTHERLY RAINS

The weather will shift gradually to south India, with an outlook valid until Saturday saying that scattered rain or thundershowers would occur over Tamil Nadu, Kerala, Rayalaseema and south Karnataka.

Back-to-back westerlies to trigger heavy weather

Active weather has once again broken out over the western Himalayan region with cascading impact for the plains of northwest India and the east as back-to-back western disturbances were on their course to hit the region.

On Sunday, an incoming western disturbance dropped anchor over north Pakistan and adjoining Jammu and Kashmir and was slowly moving into further east and southeast.

‘ACTIVE’ SYSTEM

This will be followed close on the heels by yet another ‘active’ western disturbance, which will start affecting the western Himalayan region from Tuesday onwards and adjoining plains from Wednesday onwards.

A weather warning issued by India Meteorological Department (IMD) on Sunday evening said isolated thunder squalls or hailstorms may occur over Orissa, Chhattisgarh, Jharkhand, Gangetic West Bengal and north Andhra Pradesh on Sunday and Monday.

Punjab, Haryana, Delhi, north Rajasthan, west Uttar Pradesh and Vidarbha could well be among those regions to have been taken the hit through the day on Sunday itself.

RAIN BELT

Extended forecast valid until Friday spoke about the rain belt shifting entirely to the south with fairly widespread rain or thundershowers indicated for Tamil Nadu and Kerala and scattered over coastal Andhra Pradesh, Rayalaseema and south interior Karnataka.

But fresh fairly widespread rain or snow could be unleashed over western Himalayan region and scattered rain or thundershowers accompanied with isolated squalls or hailstorms over adjoining plains presumably under the influence of a fresh western disturbance.

The emerging pattern of rains had been signalled at least two weeks ahead by some international models, which have largely retained their outlook in the latest updates.

WIDESPRAD RAIN

Meanwhile, overnight on Sunday, fairly widespread rain or snowfall was reported from Jammu and Kashmir, scattered over Himachal Pradesh and isolated over Uttarakhand as the incoming westerly system sat across the northwest border.

Scattered rain or thundershowers also occurred over Orissa, Chhattisgarh, Gangetic West Bengal and Jharkhand while it was isolated over Madhya Pradesh, Andhra Pradesh, west Rajasthan, Vidarbha and Arunachal Pradesh.

Minimum temperatures were below normal by 2 to 3 deg Celsius over east Uttar Pradesh, Bihar, Punjab, sub-Himalayan West Bengal and Assam and above normal by 2 to 3 deg Celsius over Rajasthan, Orissa and Andhra Pradesh.

The lowest minimum temperature of 6 deg Celsius during the last 24 hours ending Sunday morning was recorded at Adampur in Punjab in the plains of the country.

CONVECTIVE CLOUDS

Satellite imagery on Sunday afternoon showed convective (rain-bearing) clouds over parts of Jammu and Kashmir, Himachal Pradesh and Punjab, ready to ‘cream up’ the hills and down the slopes in the northwest. .

A short-term outlook until Wednesday said that scattered rain or thundershowers are likely over Orissa, Chhattisgarh, Vidarbha, Gangetic West Bengal, Telangana and coastal Andhra Pradesh on Sunday and fairly widespread on Monday.

Fairly widespread rain or thundershowers would occur over Punjab, Haryana and Delhi; scattered over east Rajasthan and west Uttar Pradesh; and isolated over west Rajasthan, east Uttar Pradesh and Madhya Pradesh on Monday.

SOUTHERLY RAIN

Isolated rain or thundershowers would occur over Rayalaseema, south interior Karnataka, Tamil Nadu and Kerala on Monday before scaling up thereafter.

Minimum temperatures would fall by 2 to 3 deg Celsius over the plains of northwest and central India during next three days. 

Forecasts differ on spread of easterly rains

International model forecasts continue to favour scattered rain along a northeast-southwest gradient along the east coast and immediate interior on Sunday and Monday. Moisture incursion has been indicated both from equatorial Indian Ocean (south of the peninsula) as well as from the coastal waters of the Bay of Bengal to fuel the precipitation.

Contrary to forecasts, there is no formation of any well-defined circulation in the Bay waters; it would just amount to a ‘perturbation’ of available moisture under the influence of easterly winds.

A feeble western disturbance is forecast to affect the western Himalayan region by the weekend but forecasts show the system getting some accentuation presumably from residual moisture from a prevailing ‘active’ western disturbance fanned up further by warmer easterly winds from the Bay.

This is what could likely trigger the rains along the coast and immediate interior, but which India Meteorological Department (IMD) seeks to confine to Orissa, Chhattisgarh and Andhra Pradesh.

An IMD outlook on Wednesday afternoon said that the active western disturbance would continue to affect western Himalayan region and the Indo-Gangetic plains on Thursday and the Northeastern States during the next three days.

An IMD heavy weather alert said that isolated heavy rainfall would occur over Uttar Pradesh, sub-Himalayan West Bengal and Sikkim on Thursday.

Isolated heavy to very heavy rainfall would occur over Arunachal Pradesh and Assam during on Thursday and Friday.

Isolated thunder squalls and hailstorms have been forecast over Uttar Pradesh, Bihar, sub-Himalayan West Bengal and Sikkim on Thursday and over Assam and Arunachal Pradesh on Thursday and Friday.

Meanwhile, during the last 24 hours ending Thursday morning said that widespread rain or snow occurred over Himachal Pradesh and Uttarakhand and scattered over Jammu and Kashmir.

Fairly widespread rain or thundershowers has also occurred over Haryana, Delhi, Uttar Pradesh and east Rajasthan.

It was scattered over Punjab, Assam, Arunachal Pradesh and isolated over Bihar and north Madhya Pradesh.

Minimum temperatures fell by 1 to 3 deg Celsius over Punjab, Haryana,Rajasthan, west Uttar Pradesh and north Madhya Pradesh. The lowest minimum temperature of 9.0°C was recorded at Erinpura Road (Rajasthan) in the plains of the country.

Satellite pictures showed convective clouds over parts of western Himalayan region and Uttar Pradesh.

Minimum temperatures are expected to fall by 2 to 4 deg Celsius over northwest and adjoining central India during the next three days, the IMD outlook said.

Active weather shifting base to east India

The ‘actively’ weather-making western disturbance is slowly moving away to the east of the country, which would be the focus of emerging weather over the next few days and into the weekend.

As this scene of action shifts to the east, there is a likelihood of a follow-up weakling system affecting the hills of the northwest where the India Meteorological Department (IMD) sees fresh scattered rains breaking out on Sunday.

Scattered rain or thundershowers would also occur over Kerala, Tamil Nadu, Andhra Pradesh, Orissa and the Northeastern States.

Meanwhile, an IMD weather alert said that heavy rain or snowfall is likely at isolated places over Jammu and Kashmir, Uttarakhand and Himachal Pradesh on Wednesday. Isolated thunder squalls or hail may occur over east Rajasthan, Haryana and Uttar Pradesh on Wednesday.

A weather update said that widespread rain or snow occurred over Jammu and Kashmir and Himachal Pradesh and fairly widespread over Uttarakhand during the day on Monday. Scattered rain or thundershowers was reported from Rajasthan, Punjab and Haryana and isolated over west Uttar Pradesh.

Maximum temperatures are above normal by 2 to 6 deg Celsius over central and adjoining east India.

Satellite cloud imagery on early Tuesday morning showed convective (rain-bearing) clouds over parts of Jammu and Kashmir, Uttarakhand Himachal Pradesh, east Rajasthan, Haryana, Delhi and west Uttar Pradesh.

The prevailing active western disturbance would continue to affect the western Himalayan region and plains of northwest India for the next two days and Gangetic plains and northeastern states from today (Tuesday) onwards.

Forecast valid until Friday said that fairly widespread rain or snowfall would occur over Jammu and Kashmir, Himachal Pradesh and Uttarakhand on Wednesday and decrease thereafter. Scattered rain or thundershowers would occur over east Rajasthan, Punjab, Haryana, Delhi and Uttar Pradesh on Wednesday and decrease thereafter.

Scattered rain or thundershowers would occur over sub-Himalayan West Bengal and Sikkim, Arunachal Pradesh and isolated over Bihar, Tamil Nadu and Kerala.

Maximum temperatures would fall over many parts of northwest India by 2 to 4 deg Celsius on Wednesday and Thursday as the westerly system fades away to the east.

Minimum temperatures, too, would fall by 2 to 4 deg Celsius over parts of northwest and adjoining central India during the next three days.
