Another Yellow Warning for snow and ice has been issued for the North West.
All of Cumbria and Lancashire could be affected from 5am until 10am tomorrow.
The Met Office says they're not certain about where exactly the greatest snowfall will be.
An update from The Met Office says: "Showers or outbreaks of rain will turn wintry overnight, with the risk of a more prolonged spell of snowfall late in the night and during Wednesday morning, especially in the south.
"This will give a covering of snow with 1-4 cm possible in places and locally 5-10 cm, these higher accumulations mainly above 200m. Icy stretches on untreated roads and pavements are also likely to form.
"Please be aware of some difficult driving conditions and the potential for travel disruption into the Wednesday morning rush hour."
Met Office Advisor Kevin Wadsworth said: "It may be the first day of meteorological Spring, but I’m afraid it’s not going to feel very Spring like. The next few days are going to be pretty cold, with temperatures low enough for some snow in places.
"Mostly dry this afternoon, but we’ll see some showers this evening. These will be rain or sleet at low levels, but some snow on the Fells and Pennines, where a covering is possible, especially above 200 m. It’ll become dry for a time in the middle of the night, but more showers are expected in the early hours, lasting through the rest of the night. These are going to give 1-4 cm of snow in places, locally 5-10 cm (mainly above 200 m).
"Lancashire and the Greater Manchester area look especially prone to seeing a few cm of snow on the ground from some heavy snow showers on Wednesday morning, leading to some localised traffic disruption. The showery nature of the precipitation means that some of us will see very little, whilst adjacent areas get a covering. The likelihood does increase with altitude though, and it’s certainly above 100-200 m where we’re more likely to see accumulations of several cm, leading to some tricky conditions. Clear spells between the showers could lead to some icy stretches on any untreated surfaces.
"We have a Yellow Warning of Snow and Ice in force (medium likelihood, low impacts), valid from midnight tonight to 10:00, which covers all of our area. Low impact warnings are not ‘pushed’, but you can view them in the usual way on Hazard Manager, or our website.
"Temperatures will rise a few degrees above zero tomorrow, so any snow at lower levels will melt. Staying closer to freezing on the highest routes, so any thawing here will be more gradual.
"Sunny spells on Wednesday, but more showers are likely in the afternoon/evening. These will fall as rain, sleet or wet snow at low levels, with more snow content as you gain altitude – weather warnings will be kept under review.
"Remaining cold through Thursday, Friday and the weekend, with overnight temperatures close to freezing and daytime temperatures typically 5 to 7 Celsius (colder on high ground, where snow cover remains). There should be a good deal of fine, dry weather, but we will monitor the risk of any further wintry showers."
