Tonight: Overnight tonight skies are likely to be clear initially which will allow temperatures to drop very quickly after sunset. Like last night we may well see -10C breached in a number of areas. However, later in the night the temperature fall may be arrested and even partially reversed as a band of cloud tracks westwards across the region. Potential for snow of 5cm in Oldham from 00:00hrs tonight. Wind direction 3-8mph NNE rising to 5-10mph by morning.
