Planning Outlook

Low pressure north of Scotland on Tuesday brings showers with widespread gales, severe over Scottish Highlands with steady, heavy rain, turning to snow on high tops. Pressure builds from the south Wednesday but staying blustery with rain on and off for many, hill cloud clinging to high terrain, and haze towards the west coast. Wind will lessen and shift southerly on Thursday, more bright breaks, milder temperature, and little or no rain remaining. A frontal system brings rain and wind into western areas on Friday, pushing east into evening and perhaps a very unsettled start to Saturday, but then a trend towards high pressure is indicated as the weekend goes. Northwest areas stay cloudier and blustery into Sunday, then more widely settled early next week and possibly longer, cool to mild temperatures.
