Unsettled conditions can renew flood threat across the United Kingdom

Updated Nov. 22, 2019 12:04 PM




A shift in the weather pattern this weekend and into next week will bring a parade of storms through the British Isles, increasing the risk of flooding.
This change in the pattern will come after a storm spread flooding rainfall into parts of France and Italy this weekend.
Rain will gradually taper off across the British Isles into this weekend as the storm moves away and into the Mediterranean Sea, but the brief dry spell for much of the region will be short-lived.
At the same time, a large area of high pressure over eastern Europe will begin to break down. This will shift the storm track across the continent farther north through next week.
This first storm will track across southern parts of the United Kingdom Sunday and into the beginning of next week. Rainy spells will begin to spread across Ireland, Wales and southern England Sunday night.
By Monday, rain will expand farther north into northern England and Scotland as the storm continues to spin over the region.
While temperatures across the region will be around 10 C (50 F) in most locations, temperatures closer to freezing in the Highlands can allow some wet snowflakes to mix in.
Showers can reach into France and Germany but should remain isolated before ending into the overnight hours. The next storm will follow quickly behind the first, bringing the next round of rain across the British Isles Tuesday and Wednesday.

This second storm is forecast to slow down over the United Kingdom, which can give it the opportunity to wrap up over the region. This can bring a batch of steadier rain to southern locations.
Flooding will once again be a concern with the amount of rain the area has received recently.
"Many streams are already high, so any additional rainfall can lead to areas of flooding," said AccuWeather Meteorologist Tyler Roys.
Flooding may not be the only threat from this storm depending on how much this storm is able to strengthen.
"Should this storm develop and track in a favorable fashion, wind gusts of 80-105 km/h (50-65 mph) will be possible," said AccuWeather Meteorologist Rob Richards.
The strongest gusts will be most likely along coastal areas in Ireland, Wales, western France and northern Spain. While this second storm gradually drifts into central Europe through the end of the week, another storm will take aim for the United Kingdom.
Rainy spells are once again expected to spread across the region, but this storm has the potential to bring another round of heavier rain. This will prolong the risk of flooding across the region.

With the holiday season quickly approaching, many Christmas markets have opened for business or will be beginning soon across Europe.
Those headed out to enjoy the market in Manchester next week should be prepared for outbreaks of showers almost every day.
Wet weather may impact popular Christmas markets in Vienna, Austria, Berlin, Germany, and Strasbourg, France, during the second half of next week.
