Pressure and weather in Shrewsbury
Shrewsbury's medieval centre sits inside an almost complete meander of the River Severn, on low ground in the middle of the Shropshire Plain with the Welsh hills rising twenty miles to the west. Those hills give the town a real rain shadow, so it is drier than most of the English west and considerably drier than mid Wales, but they do nothing at all to stop the river. The Severn drains a large steep Welsh catchment, and heavy rain over Powys reaches Shrewsbury a day or so later as a flood peak, which is why the town floods in winters when the Atlantic storm track parks itself over Britain. That storm track is the whole barometric story. North Atlantic depressions cross the country in families from October to March, each bringing falls of twenty to thirty-five hPa, gales and rain over a few hours, sometimes three or four in a single week. Between those spells a blocking high can settle in for a fortnight with a flat high barometer, frost in the river valley on clear nights and fog that clings to the meander until late morning. Summer is mild and changeable, with the storm track displaced north and low-amplitude variation.
What this means for you
Atlantic winters deliver storms in families, so the barometer can fall and rise three times in a week. Counting the cycles on a barometric pressure forecast describes the load better than any single reading.
