Heavy rain will once again target the United Kingdom, threatening to renew flooding with the ground still saturated and rivers swollen one week after Storm Desmond.
The heavy rain will track from Ireland to north of England and the Midlands during the first half of the weekend. This includes Manchester, Liverpool, Leeds, York, Hull and Stoke. The rain will also target Caernarfon in northwestern Wales.
"The biggest concern is the rain," AccuWeather Meteorologist Tyler Roys said.
In general, a quick 20-40 mm (0.75 to 1.50 inches) of rain will fall in a span of just six to 12 hours with localized amounts to 75 mm (3 inches). The highest totals will mainly be measured on the west-facing slopes of the higher terrain.
Although the heavy rain will bypass London, a shower or two will occur and interfere with those putting up holiday decorations or heading to Christmas markets.
"Once again, there will be an enhanced risk of flooding," Roys said. "This could quickly lead to flash flooding as rivers are still swollen."
On Friday, the Environment Agency reported that 11 flood warnings remained in effect in the north of England and Wales.
"Environment Agency teams are also busy checking the condition of flood defences and the position of pumps and temporary flood barriers ahead of wet weather this weekend," the agency said in a press release.
The heaviest rain will bypass hard-hit Cumbria. However, there can still be some rain that will slow rivers from dropping below flood levels.
Storm Desmond dropped widespread rain totals of 180-200 mm (7-8 inches) across the Lakes this past weekend.
A rain gauge at Honister Pass measured a record-breaking 341 mm (13 inches) of rain in only 24 hours.
On the southern fringe of the rain, there can be a brief period of wind gusts to 45 mph (75 km/h) across Wales and the Midlands.
Meanwhile, enough cold air will be in place for the rain to mix with or fall as snow in some communities.
In the higher terrain near the southwestern border of Ireland and Northern Ireland, "Snow will mix with rain at times with the potential for around 5 cm (2 inches) into Saturday," AccuWeather Senior Meteorologist Alan Reppert said.
Snow will also develop in the Pennines on Saturday, while rain falls in the lowest elevations.
Any snow in the higher terrain east of Manchester will quickly change over to rain.
However, it will likely stay all snow in Pennines to the northeast of Manchester. A total of 8-15 cm (3-6 inches) with more locally threatens to cause travel disruptions.
On the heels of this rain, another depression will approach the British Isles later in the weekend. The associated rain will lift from Ireland to Scotland on Sunday.
"There could be snow issues in the Scottish Highlands later Sunday," Roys said.
Showers will then spread across the British Isles on Monday. Since the depression will be weakening, widespread heavy rain, renewed flooding and strong winds are not expected.
The depression will make it difficult to view the peak of the Geminid Meteor Shower Sunday and Monday nights. Southeastern England, will have the best opportunity to see some breaks in the clouds and catch a glimpse of the show Sunday night.
