But I would wait and watch to forecast precipitation alomg the Konkan regions. Because, by this time, an active W.D. coming along would dominate this southerly system, and not allow it to "grow" further.
Days in the western regions were very hot on Monday, with Chorr (Pakistan) at 38c, and Rajkot and Veraval also at 38c. Mumbai was at 36.6c ! ( IMD map shows the heat clearly).
With the W.D. we can expect a reasonably good drop in the temperatures,starting from the nortwestern areas, and more effectively in the night temperatures from this weekend. Also, rains could be expected in the plains of northern India and lower and middle hills from 4th. for a couple of days. And ofcourse snow in the upper hills.
