OK…after having changed clothes due to trying to film the passage of the comma-head of the bow echo here in Trussville, I checked the Birmingham airport observations. Some things you don’t see in there every day.

The GR means hail, and the “GR 1″ in the comments at 0814Z indicates 1” hail (about half-dollar size).
The SQ means “squall”, a sudden burst of wind. Peak wind was 41 knots (47 mph) at 0802 UTC.
CONT LTGICCCCGCA means constant lightning, intracloud, cloud to cloud, cloud to ground, and cloud to air.
P0062 means 0.62″ of rain fell between the last hourly ob at 0753 and 0814.
Got some southerly winds here in Trussville, some debris flew past me (leaves and twigs). My wife commented she was glad it wasn’t something heavier.
