Satellite loops show thunderstorm developing in bands across the area. Surface observations reveal pronounced convergence zone with low T-Td spreads and dew point values between 19 and 21 °C. Corfu's stations report Temperatures around 25°C and dramatic drop in pressure. These conditions, combined with the fact that mean tropospheric flow (around 15 m/s) is parallel to the convergence zone, point to a very high threat of cell training and subsequent excessive rainfall events in NW Greece and Albania the next 4 hours.

Moreover, with LLS above 10 m/s and low LCLs (~900m), if storms can develop rotation, perhaps aided if they move over the convergence zone with enhanced vorticity, tornadoes can not be ruled out.
