The outing for the "Mumbai Birdwatcher's Club" at Uran turned out to be favourable, weatherwise, with a great opportunity for the birders to spot and identify many types of grassland birds (a rare albino Prinia) and plenty of water species. Most of the 15 mm of rain had fallen on Saturday evening/night, and the day was cloudy.

Well, the rain has just eased a bit on Sunday, as at least 25-30 mms of rain is now expected on Monday and may extend into Tuesday. An upper air circulation formed over south Maharashtra should result in heavy rain in madhya Maharashtra, Marathawada and south Gujarat on Monday/ Tuesday. As the circulation dissolves in the Arabian Sea, the effect of the rain will diminish.The circulation over south Maharashtra and a distorted wind formation, away from the seasonal expectation, is seen in this map.
But with the Bay showing no signs, as yet, of brewing another low in the next few days, drier weather will return mid week onwards in most parts of central, southern and northern India. As is seen in this temperature map, the red area (hot) has now crept southwards.

Many parts of the Middle East are still very hot, with Basra (Iraq) being the hot spot at 48 c and Yenbo Airport (S.Arabia) at 47 c. Pakistan's highest was at Bhawalnagar which recorded 41 c. Keeping a track at the Gulf and Pakistan day temperatures is necessary so as to keep a track of the changing wind pattern and subsequent rising of sea level pressure over Arabia/Pakistan, indicating change of season. However, the temperatures are still too high for a change yet.
