  1. Gfs looks good today for most parts of TN, some rains also pushing near the vicinity of Chennai later this week

  2. Update from the US: Heavy rains expected through Monday for New York, New Jersey, Washington DC and Philadelphia. An inch or two of rain possible along with isolated hail storms. 40% chance of tornado forming close to north of Philadelphia and south of New Jersey.

  3. The national capital on Sunday witnessed the hottest day of the season so far as the mercury level crossed the 40-degree-mark for the first time, settling four notches above the average. For Monday the maximum and minimum temperatures are likely to hover between 41 and 23 degrees Celsius,” Imd

  4. Today convergence of eastern and western winds expected in the north interior TN…and thunder storm activity is expected

    • There is no much use in predicting weather rain occurs or not at a place….its value in predicting destructive hurricanes/ cyclones to minimize the loss of life and property is a boon

  5. A low pressure area with combination of warm southerly winds and cold air aloft moving in out of Siberia continue to produce strong to severe thunderstorms resulting in heavy rainfall across Japan and some breaking rainfall are expected across central Japan today.

    It dumped huge rains in some of the islands ofJapan in extreme South on April 18th.
    Tokorono (Yonoguni Airport ) – 251mm
    It has received 220mm in just 3 hrs and out of which 123mm in just an hour.
    Yonogunijima – 210mm
    Iriomotejima – 96mm

    • This system pounded some areas of Okinawa islands from Yesterday 5pm and till 12 noon today few notable rainfall are as below

      Amagi – 228mm out of which 183mm today
      Isen – 203mm out of which 124mm today
      Koniya – 157mm

      • Meanwhile JMA have warned landslides and flooding warning to entire central Japan coastal areas.

        Many stations of Kochi, Tokushima, Mie and Nara have record over 100mm already and today Shizuoka Prefecture and coastal areas of Tokyo and it’s surrounding Chiba and Kalakaua ptefecture might end up with surprising huge numbers as per JMA.

  6. A high pressure area in place provides dry and pleasant weather for Portland, Oregon. The rain will return on Wednesday with a cool down.

    The temperature might cross 25 C on Monday, which is summer like for Portland!

    • Expecting this convection will further flare-up (strengthen) and will throw up pre-monsoonal LPA over the same area???

  7. Rsrao

    Even i have the same feel around 23rd to 25th, there may be some rainfall activity.
    Forecasts suggest even till 27th there is a chance. I feel that 24th and 25th would be the day.

    parthasri35, Rajakilpakkam • 3 days ago

    UAC – 23rd to 25th seems to be promising, CC at 850 HPA over North Coastal TN, Lower level ridge at 700 HPA just above Chennai latitude, this might pull something??

  8. Moderate Rains continue in Tamil Nadu ending 8.30 am on 19.04.2015

  24. 24th Night / 25th Morning looks like a deluge kind of spell. This time the build up will be more. Blog should get hyper active on 24th/25th/26th/27th.

  25. Today in Chennai almost all towering clouds were spreading out into an anvil kind of structure in mid levels , right from the morning I was able to see almost all clouds behaved the same way till the day ended ..The reason I feel could have been behind is the mid level negative vorticity ….

  26. Vignettes from the past- 2005 NEM.

    Northeast monsoon arrives early in Tami lNadu.

    The northeast monsoon has arrived, bringing cheer to citizens and water managers alike.

    The Meteorological Department said in an official release, “The monsoon has been active over Tamil Nadu and Kerala.” The current spell of rain was caused by the presence of a low-pressure area over the south-west bay and Tamil Nadu. Besides Kerala and Tamil Nadu, the adjoining areas of Karnataka and Andhra Pradesh received rain in the last 24 hours ending 8.30 a.m. on Wednesday.

    The maximum rainfall of 14 cm was recorded by Ponneri in Tiruvallur district, followed by Thanjavur – 11 cm, Chennai, Thuckalay, Melur, Devakottai and Tirupattur (Sivaganga district) – 9 cm each and Dindigul – 8 cm.

    On Thursday, rain or thundershowers are likely at most places in Tamil Nadu, Pondicherry and Kerala, many places over south coastal Andhra Pradesh, Lakshadweep, coastal and south interior Karnataka and a few places in Telengana and north interior Karnataka.

    Monsoon forecast

    Though the department has not yet come out with the monsoon forecast, the International Research Institute for Climate Prediction, part of The Earth Institute at Columbia University, United States, in its climate outlook bulletin issued last month for Asia had said, “Enhanced probabilities for above normal precipitation are forecast for southern India and Sri Lanka.”

    On an average, the State receives 48 cm rainfall during October-December, accounting for 50 per cent of the annual rainfall. Meteorologists feel that given the less predictable character of the monsoon, it is an uphill task to make any forecast.

    No satisfactory forecast model is available for the northeast monsoon. Different research organisations are working in this direction.

    What has gladdened water managers is that after a gap of eight years, the monsoon has arrived in the first half of October. The last time this happened was in 1997, when it set in on October 13.

    Since then, it has been in the second half of October or early November.

    In 1997, the State received 52 per cent more rainfall than normal.

    Except in 1998 when the State had excess rainfall, there was deficient or normal rainfall in the last seven years.

    During this year’s southwest monsoon (June-September), Tamil Nadu and Pondicherry had normal rainfall with 29 cm against the anticipated 32 cm. Except for six districts with deficient rainfall and Tirunelveli recording excess, all others fell under the “normal” category. Chennai was among the deficient districts, receiving 32 cm against the normal 44 cm.

    Point to note from the report..

    On an average, the State receives 48 cm rainfall during October-December, accounting for 50 per cent of the annual rainfall. Meteorologists feel that given the less predictable character of the monsoon, it is an uphill task to make any forecast.

    No satisfactory forecast model is available for the northeast monsoon. Different research organisations are working in this direction.

  27. The average rainfall at the three reservoirs — Red Hills, Cholavaram and Satyamurti Sagar at Poondi — was 585 mm -2005 October..

    The highest rainfall for October in the last four decades was 656 mm in 1969.

    Till now, the rainfall in October 1972 had the second best tag with 506 mm..

    Past 2005, i doubt whether the three reservoirs would have got any close to the above figures..

  28. As per news report Kunderipallam Dam, 20 Kms from Sathyamangalam, Erode District, Tamil Nadu.over flowing and flood alter has been given for 10 villages
