 19th May

As on 19th, Monsoon not been established in Kerala, and therefore there is no official declaration of the Monsoon ( By IMD or Vagaries)....Explained below, it will be another 4/5 days before the Monsoon sets in over Kerala in strength.

A brief note on Southwest Monsoon - When Onset happens over Kerala, an offshore trough forms off the coast. Cyclonic circulations embedded in the UAC are common features, which help in northward advance of the Monsoon. 

At present, at 850  levels, the west/northwest wind convergence is seen near Kerala due to the UAC located near Kerala/TN border. There is no offshore trough. 

Tropical easterly jet at 200 hpa hasn't set in either. Additionally, the westerlies are not seen extending well into Tamil Nadu due to the UAC. 

With heavy falls over Kerala, the notion of Monsoon rains seems practical, but not as a set system...Such pseudo onset like conditions have happened  in the past, and mentioned in Vagaries a few times earlier. The rain with low clouds feels like Monsoon. But technically, considering the various above factors, proper atmospheric conditions of the Southwest Monsoon have not been established..

 

Maharashtra: Pre-Monsoon thunderstorm outlook for May 19-20.

🌧Rain/thundershowers likely in south Madhya Maharashtra districts of Kolhapur, Sangli, Solapur and Satara during next 2 days. 

Parts of Pune and Ahmednagar districts can get patchy rain/thundershowers.

Southern districts of Marathwada region such as Latur, Beed and Nanded can expect some thundershowers in parts. 

With the UAC expected to move north over land, parts of north Karnataka to also receive moderate to heavy thundershowers. 

महाराष्ट्र: 19-20 मे साठी मान्सूनपूर्व वादळाचा अंदाज.

पुढील 2 दिवसांत दक्षिण मध्य महाराष्ट्रातील कोल्हापूर, सांगली, सोलापूर आणि सातारा जिल्ह्यांमध्ये मेघगर्जनेसह पाऊस पडण्याची शक्यता आहे.
पुणे आणि अहमदनगर जिल्ह्यांतील काही भागांत ढगांच्या गडगडाटासह पाऊस पडू शकतो.
मराठवाड्यातील दक्षिणेकडील जिल्हे जसे की लातूर, बीड आणि नांदेडमध्ये काही भागात मेघगर्जनेसह पावसाची शक्यता आहे.
