Update Weds 20:25hrs: Gale warning for South coast and exposed hills: SW wind 30mph+ GUSTING 40-50mph Thursday pm. Channel will experience v strong winds.
A deepening LOW pressure is winding up off the west coast of the British Isles and will cross the UK this week bringing cloud, rain and strong winds and cooler temperatures. Reigate and the SE, however, will remain comparatively sheltered from the worst of the rainfall, probably only amounting to 10mm over the next 10 days or so, which isn’t much compared with the deluge elsewhere. The first fronts make an entrance tomorrow with moderately heavy rain for Wednesday, slowly clearing off in the afternoon. The most interesting bit of weather looks like Thursday overnight into Friday when strong south westerly winds circulating around the LOW cross our region, gusts around 50mph are possible in exposed areas like the North Downs around Reigate. The BIG map shows wind arrows circulating around the centre of the LOW as it moves across Northern England and Southern Scotland (wind speed in mph). Friday looks pretty wet all day and Saturday could bring a threat of thundery showers. The unsettled regime continues with blustery westerly winds throughout the weekend keeping temperatures around the mid teens. Weekend looks blustery and unsettled with showers Saturday, some thundery possible.
The longer term May forecast looks rather unsettled especially for Reigate with LOW pressure likely to sit over Europe bringing rain to the SE, while higher pressure sits over the North and West of the UK bringing better conditions to those regions. The graph shows more rain through the rest of May showing this sort of set up. Lovely!
