Key points from the present forecast
The next 20 days forecast indicates that
 Western disturbance activities are likely to cause precipitation over the
western Himalayan region during last 3 pentads with above normal
precipitation during 2nd and 4th pentads.
 A feeble easterly wave trough is likely to cause normal rainfall activity over
southern parts of Tamil Nadu during the first pentad.
 Remaining parts of India is likely to experience dry weather which is normal
during this part of the season.
 North India may have respite from cold wave with normal to above normal
temperatures during all the 4 pentads. Below normal night minimum
temperatures are likely over south peninsula during 1st , 2nd & 3rd pentads
due to clear skies and radiational cooling resulted from continental dry air
replacing the warm & moist maritime air.
 MJO associated convection is moving towards Central Pacific and a fresh
spell of MJO associated convective anomaly is expected to appear over
Western Indian ocean and expected to move eastward.
