Looking at my weather station charts for today:

There was almost 2 mb sudden drop just before 0800 and then a few
hours later around 1300 a sudden 1mb rise. Not seen that before here.


How did that tie in with the weather? On the leading edge of the rain
yesterday afternoon, there was a line squall over southern
England noticeable on the radar. Passed through here just after lunch
with rain hosing against the windows for a short while. A neighbour's
SW-facing bedroom window was wide open at the time - as per usual - and
must have let a lot of rain in. Squall appeared to dissolve on reaching
London.
