Almost similar case ! This generally happens during the reinforcement of Northeasterly winds in response to strengthening of Eq Trough !!1

There is no possibility of dryline TS formation during NEM. Many twitter handles/newbies have been misleading people for many years without knowing the real meaning behind it. Dryline TS forms as a result of interaction of hot,dry winds with moist maritime air mass. In our…

See how many attempts these clouds are making to break the inversion & develop freely as Congestus & subsequently into a thunderstorm.. Interesting time-lapse shows the early morning developments associated with land breeze convergence near the coastline adj waters. Mobile…
