A yellow, be aware snowfall warning has been issued for parts of the Midlands & Southern England for tonight. A “trough” is expected to pep up precipitation across England & Wales tonight. This precipitation may fall as sleet or snow above 200 metres of elevation, producing potentially up to 2-5cm of snow for parts of the Central Midlands, East Wales and northern home counties in areas at or above this elevation (200m). A tricky forecast, because it remains uncertain whether or not snow will accumulate to lower levels, and the bigger populated urban areas.
The Met Office Snowfall Warning spans south east Wales, much of the Midlands & into East Anglia. A separate snow & ice warning has been issued for Northern parts, this encompasses showery snowfall expected in the coming few hours, from a polar maritime flow.
As explained, most areas are likely to see rainfall, especially to lower ground and especially south of the M4 corridor. The chance of snowfall increases for higher parts of Wales, the Midlands & East Anglia, above 100m the risk increases to around 30% and to around 50% above 200 metres of elevation. The snow should melt quickly on Thursday to lower levels. However, there is a risk of travel disruption as this precipitation is likely to coincide with the Thursday morning rush hour. Once again The Peak District is likely to be impacted by some snowfall early on Thursday. This morning may higher routes were closed, including the A57 Snake Pass, many of which are slowly reopening this morning.
