I have just received the following forecast from the North West Met Office:
“A fragmented band of mostly light sleet/snow is currently edging its way slowly NE’wards across the region with Cheshire, Merseyside and west Lancashire the areas affected at the moment. A flash warning for heavy snow covering a swathe of the country including Cheshire was issued by the Met Office at 0240 this morning but the radar appears to confirm that most of the precipitation is currently light. This band of sleet/snow will continue to make erratic NE’wards progress across the region today. Amounts of snow are likely to be small (typically less than 1cm, in some places no more than a dusting) although parts of Cheshire and possibly Merseyside may see a little more but not the amounts likely to cause any significant disruption to transport networks etc. Temperatures today, like the last few days, will reach around +1/+2C at low levels so where little or no new snow falls further slight thawing of existing old snow will take place. Higher up any thawing will be minimal. This evening and tonight precipitation will gradually die out from the south leaving most parts dry but cloudy. Temperatures hovering around freezing for many so still an ongoing risk of meltwater re-freezing.
Tomorrow will be another cold, cloudy but largely dry day with continued slow thawing of any lying snow at low levels and similar temperatures to those of today.
Then for Friday and Saturday the weather will turn more generally unsettled with rain and strengthening winds spreading to all areas by Saturday, accompanied by slightly higher temperatures (typically +3 to +5C at low levels). Whilst this should ensure most, if not all the leftover snow/ice thaws away at low levels the picture is not quite as straightforward as it seems. There is a definite possibility that over the Pennine areas (and possibly the Cumbrian Fells too) Saturday’s rain will turn to sleet/snow as colder air is drawn back in for a time.”
