Remaining cold this weekend – further wintry precipitation
The cold and wintry conditions are set to continue, as I have been highlighting in previous blogs and whilst there is likely to be a window of quieter weather for most on Saturday there is now a growing risk of yet further wintry precipitation developing later on Sunday and into the new working week.
At this stage there are some uncertainties over which areas are at greatest risk as the weather patterns that are expected to bring this renewed risk of rain, sleet and snow are complex. However, latest forecast model data and thinking is that a weather front, in association with an area of low pressure to the south or southeast of the UK, is forecast to move north and west into central and eastern areas of England in particular later on Sunday and overnight into Monday.
Precipitation is likely to fall as rain or sleet at lower levels (coasts and below 100–150m) in eastern England but further inland and especially above 200m then further snowfall is expected across parts of Eastern England.
I have highlighted, on the forecast map which areas I believe are at greatest risk of snowfall in red and a lower risk across the yellow areas. At the moment snowfall amounts are likely to range between 2cm and 5cm within the red areas, but locally heavier bursts of precipitation cannot be ruled out and this may result in snowfall totals across parts of Yorkshire and the Pennines for example reaching up to 10cm.
The timing of this event may well coincide with the Monday morning rush hour across eastern areas of the UK and as a result some travel disruption may be possible.
