The W.D. mentioned moved eastwards into India, and formed a secondary low,aloft, at 25N. As a result,there was some rainfall in the states of Gujarat and Rajasthan, and some light rain in Mumbai on Friday/Saturday.The secondary low has attracted moisture clouds from the arabian Sea towards it.
But the W.D. has brought good rain/snow in the northern hills,especially in H.P.
Higher reaches in the upper Manali region experienced a fresh spell of snowfall while the lower parts of the areas received widespread rain.The Rohtang pass, gateway to Lahaul-Spiti district, including Pir Panjal ranges, Bhrighu ski slopes, Marhi meadows, Gulaba, Hamta ski slopes and Chanderkhani Pass also received fresh snowfall.
Higher reaches in Kullu had snowfall and the lower region had rains on Friday. Peaks of Mattikochhar, Mout Nag, Phungni Devi and Bijli Mahadev experienced snow today. The minimum temperature recorded at Bhuntar remained 2.7°C.
The IMD streamline map shows the winds turning to the north-south direction today. Hence, as a result, with the moving away of the current W.D.,we may expect the night and day temperatures to drop substantially in the northern states,after Tuesday. The minimums will also drop by 4-5c in the states of Gujarat and Maharashtra from Tuesday. Hence, the lows in Pune may go down to 10c, and in Mumbai 15c after Tuesday. Cities in Gujarat may see a low of 9-10c also.
Meanwhile, I do not see any more systems coming from the bay now.The ICTZ is now seen moving southwards. This is established by the fact that now 2 cyclones have been formed in the southern hemisphere in the last 3 days.Hence, the rain bearing systems bringing rain to T.N. cease.
