4C rising to 8C, locally warmer western areas by afternoon.
Freezing Level
Frost inland glens and some sheltered higher areas at dawn. Otherwise above freezing to the summits.
Planning Outlook
Staying dry through the remainder of this week and likely into the weekend as high pressure centred to the north stays nearby. Strong and gusty easterly winds tending to lessen later in the week to leave mostly light winds onward into the weekend. Temperatures generally a few degrees above freezing on higher tops, though often some frost in valleys and sheltered higher terrain at dawn. Western areas generally sunniest and warmest, some low cloud banks over eastern hills in the mornings, early fog patches some valleys. Commonly dry weather likely into next week too, chance of local showers occasionally.
