Temperature: 12°C (54°F) Cloud: 7/8 Oktas, Cumulus, Nimbus Activity: Light rain passage of a cold front air now unstable at 030° Possibly thundery on back edge Wind: 10mph W (variant NW)
MSL be prepared for thunder - I can see that cloud its very very black and go an overshooting top - possible tornadic although im right in thinking it is moving away though a might be wrong
Well the cold front has passsed that is going to drag down cold air anyhow - I think the fact that the massive low is from a cold source and that the air is so unstable dragging down cold air from the upper atmosphere
