Typical winter conditions throughout the forecast period with the subtropical high pressure ridge to the north of the region.

Some fog affected the region this morning with radiational cooling of moist low level air but some clouds hampered radiational cooling later towards the morning,largely dissipating the fog.

Some pre frontal showers in northwesterly flow tonight and into tomorrow before a cold front brings heavier showers and possible thunderstorms from evening.
