Mawsynaram leads the All India SWM Rainfall Toppers from 01.06.2014 to 15.07.2014

This year SWM Toppers are giving a bleak picture compared to last 4 years race. The stand out performer is Mawsynaram which is leading the 2nd place Cherrapunji by 1000 mm, which is still in deficit. But the rains in Karnataka and Maharashtra have picked up after 15th July. Hence, watchout for the month end toppers. There would be drastic change in the toppers.

Major Developments:

Monday 21st: The current UAC over Odisha (on Sunday) is expected to track Westwards . The upper air trough subsequently formed, will guide the UAC westwards, and as it tracks west, it may form a Line of Wind discontinuity within the trough on Monday 21st. IF this materialises, then very heavy rains can be expected in Eastern/Central MP...roughly covering the regions around Jabalpur and Bhopal. 
Anyway, good precipitation is expected on Monday in Central MP and parts of adjoining Vidharbh.

Rainfall In Mumbai from 8.30 am to 8.30 pm IST Tuesday: Colaba 127 mms and Scruz 78 mms

Colaba season's total crosses the 1000 mm mark and is 1037 mms...NOW ABOVE NORMAL

Nagpur Lashed with 109 mms in 9 hrs from 8.30 am !! Wardha gets 85 mms and Amraoti 48 mms in the same period.

Reasoning and Answer to a query: Except for an unusual 119 mms at Colaba, we have seen between 20 mms and 50 mms at a majority of stations in Konkan and coastal Karnataka on Tuesday. 

The UAC from BB-3 has formed a UAC  in the gulf of Cambay. This was mentioned in Vagaries' Sunday blog. However, the  500 upper air level also sees a horizontal trough along the 20 N line (approximately)..

Mumbai Close Up Satellite..Monday Evening..Surrounded by Medium heavy rains...

BB-3 has weakened. The associated UAC at 500 hp is prominent over Central India and would run as a trough westwards next 12-18 hrs. UAC descends to 700 hp over Eastern MP/Chattisgarh...
