Now 2cm down.

Got heavy snow now.

Very likely February's CET will be atleast 6C.

Still got 2/3ft drifts next to dry stone walls.

Spah1 Glossop too low down too sheltered.

20cm level here.

7cm level snow.

Does anyone below 200m have settling snow?

5/6cm here now.

Looked again closer could be a fairly widespread area of moderate wet snow 8am-1pm, very locally up to 2cm but generally a dusting west Lancashire with more limited accumulation east of the M6 until you get above 150m East Manchester, down to 100m North of Manchester.

I'm not seeing anything more than a dusting away from the favoured Pennines. Perhaps parts of West Lancashire / Wirral may reach 1-2cm but very limited bulk of Greater Manchester and Cheshire.

In general forecast amounts have increased over 300m and decreased on low ground. This due to a faster moving front which pushes in milder air quickly but as conducive conditions persist at elevation, above around 300m will benefit from the heavier precipitation associated with a more northerly track. As it stands a spell of sleety precipitation within the shield Macclesfield to M6 with some brief wet snow with dustings possible above 200ft around the Wirral. This phase lasting 2-3 hours before a quick lift of the snow line to 250m+ and North East of Macclesfield forecast by around 2pm, and 200m+ North East of Oldham. To the East of the Pennines again brief accumulation to lower levels before the snow line rises to 200m+ through the afternoon.

Thoroughly knackered today so no update.

northwestsnow You do well in an easterly front aswell especially 250m+. Remember it's the drop in elevation on the western side of the Pennines that causes the air to dry and warm. So if Manchester was above 200m it'd still get snow, albeit lighter than 200m further East. @Joe Bloggs it's very rarely discussed.

Joe Bloggs Blame the last 800 million years of geological uplift and last 10 or so glacial periods for calving away the central Cambrian mountains. It's because of how extensive the high ground is. 60-70 miles of 300-600m land to your South East, whereas only 30-40miles to your east but Kinder plateau is there. However in a convective flow the topography to your east allows some intensification into Glossop / Oldham and into East Manchester and helps keep some intensity further West aswell. This is not the case on a frontal system as convective flows have different physics involved.
