Additional notes and correction to my earlier report for Wokingham.
Inspection of the hail pad shows that hail did fall in the squall this
afternoon, but the stones were nearly all 1 to 2 mm dia, with just an
occasional 3-4 mm one. Inspection of the Munro anemometer trace shows a
gust of 40 kt at 1526z. The pressure kicked up 1.8 mbar in the squall.
