A mixed October; cool spells and some warmer periods too
*1st to 12th* October
The cool and unsettled conditions look as though they'll be continuing through the short term period it low pressure in control and providing all areas with a mixture of spells of rain followed by blustery showers and a tendency for cooler weather to dig in occasionally behind as the systems clear and the evidence of colder more northern latitudes are felt.
*12th to 15th* October
Around the middle of the 2nd week of October it turns milder but remains unsettled as the flow reverts to a mainly westerly to at times south-westerly orientated direction with low pressure in control. With this being mid-autumn as you would expect it'll be windy at times with gales in exposed western and north-western area, rain for all of us some of it potentially heavy and persistent, blustery showers and cooler weather following on behind.
*15th to 21st* October
The middle of October see's potentially the first 'dig' of true polar air, showers turning wintry over higher ground in northern Britain, these carried on a brisk and very noticeably colder northerly wind, pushing deep into southern England, showers scattered in western areas, widespread through eastern and northern parts.
21st to 31st October The conditions turn less cold for a time as pressures rise and settled, this quickly replaced by an unsettled milder weather, as low pressure 'steams' in off the Atlantic, wet and windy for all areas through the third week of October. Low pressure remains in control of the pattern through to the end of the month, the flow orientated from the west or northwest, bands of rain and strong winds, alternating between brighter and showery conditions and see-sawing temperatures as Atlantic and polar / North Atlantic sourced air crosses the UK.
