Predicting weather is a NOT a easy job

Throughout the globe observations are taken at three hours interval starting from 0000 [hrs UTC]. There are different charts that are prepared and based on the charts [1] High & Low pressure are plotted [2] prevailing winds direction and speed are noted [3] and other meteorological and basic weather parameters like surface air temperature, rainfall etc are incorporated in surface chart. Later this chart is being analysed. Similarly upper air charts are also plotted analysed. Then the meteorological parameters are fed into models which uses dynamical equations, hydro static equations and the equations of motions and climatology of the region to evoluvate weather.The model out put is used for forcast.Then based on their experience and based on the climatology of a place a forcast is evolved. However some time, alas, whether parameters drastically change [especially in tropical areas] amd of course the result also varies. (You are right.)

All India Summar Monsoon Rainfall AND Farmers ..???

Farmers mainly depend on the timely forecast on RAIN. All India Summar Monsoon Rainfall [AISMR] is a major rainy season for entire India except Tamilnadu. However the vagaries of monsoon in time and space affects mainly agriculturalists. A simple solution is to have more dependentable raingauges in all locations at an interval of say 10km [i.e roughly one raingauge for every 250 square km]. This will help identify rainfall pattern of a patricular region say taluk wise. Taluk level rainfall summary, even if possible to block level, will help enumurate drough and flood in a precise manner. Long term irrigation plans based on the taluk / block level rainfall data will be more realistic. This will help farmers too. Irrigation and agricultural stragies can be planned on the rainfall summary. Precise drough / flood affected locations can be identified. In real practise each state government is maintaining atlest one raingauge st taluk level. No taluk level rainfall summary is arrived at by any taluk or district level administration in India. Of course IMD is disseminating district level rainfall summary. But atleast taluk level rainfall summary will be more useful. Since district some time may spread to different climatological zones at certain places and at certain time the district level summary may not reflect realistic rainfall distribution.

Western Disturbance

The weather system popularly known as Western Disturbance (WD) affects
day to day weather of northwest India during the winter season. The approach of WD is usually associated with cloudy sky, rise in night temperatures and precipitation on some occasions. In the rear of the system, clear sky and cold wave conditions are the common weather phenomenon over the Indo-Gangetic plains. On some occasions, dense fog and cold day conditions is also a common phenomenon over this region. Such stable weather conditions sometimes continue till another WD affect the region.
This January, a WD caused light to moderate precipitation at many places
over northwest India mainly on 2nd and 3rd. Thereafter due to the favourable conditions of moisture, temperature and winds, dense fog is prevailing over most parts of Indo-Gangetic plains except on 6th and 7th when the density and duration of fog was lower due to strong surface winds. Cold day conditions prevailed over Punjab, Haryana, north Rajasthan, Uttar Pradesh and Bihar where the maximum temperatures fell below 16° C. Delhi also experienced dense fog and cold day
conditions during this period. The lowest maximum temperature of 12.1° C was recorded on 8th January 2010 which was 9.0° C below normal. However, such extreme cold weather conditions are not very uncommon during January. In the recent past, Delhi recorded the maximum temperature of 12.1° C on 4th January 1980, 11.6° C on 10th January 1999, 12.4° on 5th January 2001, 11.2° C on 1st January 2003, and 12.4° C on 1st January 2004.
Fog/Shallow fog conditions are likely to prevail during next 1-2 days over
Indo-Gangetic plains.
The latest meteorological analysis suggests that a fresh western disturbance is likely to affect northwest India on 12th and 13th January. It will cause fairly widespread snowfall over Jammu & Kashmir, Himachal Pradesh and Uttarakhand.
Light rainfall at a few places would also occur over plains of Rajasthan, Punjab,Haryana, Delhi and Uttar Pradesh. In view of obscured sky conditions due to lifted fog/low clouds, cold day conditions may continue. Dense fog conditions may reappear over Indo-Gangetic plains after 14th provided wind remains favourable.
In addition, due to confluence/merger of winds, light to moderate rainfall is also likely over parts of central and east India during 11th to 13th January.

On Jan 15, watch the ring of fire

In a week, a rare celestial event will mesmerise skygazers in southern Tamil Nadu and parts of Kerala. A ring of fire will adorn the afternoon sky

over Dhanushkodi near Rameswaram, Thiruvananthapuram, Tirunelveli, Nagercoil, Kanyakumari, Madurai, Thanjavur and Nagapattinam for 10 minutes on January 15, making it the first annular solar eclipse to be seen from India in 45 years. The rest of India will have a partial sighting.

An annular solar eclipse happens when the disc of the moon covers the central part of the sun, leaving only a ring-like peripheral region visible from some parts of the earth. This happens when the earth comes closest to the sun while the moon is at its farthest position in orbit. In such a situation, the disc of the moon cannot completely cover the sun's surface and a fiery ring is visible beyond the moon's edge. The last time an annular eclipse was viewed from India was on November 23, 1965. The next one will be on December 26, 2019.

The track of annularity, or the patch of land from where this celestial event can be viewed, will start from Africa and cross the Indian Ocean to end at Shandong Peninsula in China. "The temple town of Rameswaram will lie very close to the central line and the annularity there can be seen for a duration of 10 minutes and 7 seconds starting at 1.17 pm and ending at 1.25 pm. This is a very long period given the average durations of annular eclipses," said M P Birla Planetarium director (research & academic) Debi Prosad Duari.
