14 day UK: Cold and wintry

Issued Sunday 25th January 2015

Week 1

After a quiet start cold and wintry conditions return.

Monday: Rain clears away from the south to leave brighter conditions across the country, but in Scotland there could be scattered wintry showers. Temperatures ranging from about 4C (39F) in the north to 9C (48F) in the south west.

Tuesday: Across England and Wales cloud amounts will be variable and in the west there could be some light rain. Rain is also possible at times in Scotland. Temperatures remaining close to the late January average.

Wednesday: Heavy outbreaks of rain are expected to sweep south eastwards with colder and clearer air following behind. The rain could turn to sleet or snow in places along its back edge. In the clearer air heavy showers will develop and readily turn to snow in the north. Accumulating snow is expected, especially over higher ground.

Thursday, Friday, Saturday, Sunday: Cold conditions are expected to persist nationwide. Wintry showers could be heavy and prolonged at times, particularly in the north where significant accumulations of snow are possible. The best of the drier and brighter conditions are forecast to be in the south, but even here showers may bring a mix of rain, sleet and snow.

Forecast confidence is moderate to high on the general overview, but the snow risk during the second half of the week is uncertain.

 

Week 2

Cold but possibly becoming milder later.

The week is expected to begin with cold and showery conditions. Showers predominantly of snow in the north but more of a wintry mix farther south. The showers probably become increasingly scattered during the early part of the week. Sharp overnight frosts are likely.

During the second half of the week cloud and rain along with milder air may return from the west.

Forecast confidence is low to moderate.

Overview

After a quiet start to the period an unstable and cold north westerly flow is expected to develop. Temperatures at the 850hPa level in the south again look quite marginal. In the north the risk of snow is significantly higher.

Towards the end of the first week there is a chance of disturbances in the flow bringing an increasing risk of more prolonged spells of rain, sleet and snow. Details at this range are very uncertain and need watching in the coming days.

The early part of the second week could see high pressure bringing drier but still cold conditions and this may be when the risk of sharp nighttime frosts is at its highest.

Through the rest of the period a milder westerly flow is favoured to return.
