So the data shows that the event was associated with cloudiness upsurge. It looks like the most dense ("thunderstorm-like") clouds detected by radars were in the area about 1-2 hours before the event.

Satellite's pictures (taken about every 30-minutes) show some new details - development of thick high-altitude cloudiness in the area.
Below are GEOS-12 pictures (taken from the National Oceanic and Atmospheric Administration (NOAA) Satellite Active Archive for the region N 27.7-29.7 deg., W 80.3-82.3, i.e. centered at the place of the event
