Here is my latest stab at how I feel the Autumn Season will progress as we move well into the second half of the year now
So what will be the theme of Autumn 2013. Dry, Wet, Warm or Cold, read on and I will try and predict how I see things panning out. Autumns in general can be very changeable with some Septembers being like Summer with less daylight while Novembers can be cold, frosty and foggy at the other end of the spectrum. Here's how I see these three months in 2013.I think September as a whole will see a good deal of dry and settled weather with High pressure close to or over the UK for large periods of time with some warm weather to be head too with temperatures overall above the long term mean. There will be some shorter more unsettled spells with some rainfall but the month will probably end up drier than usual. Night's will be chilly at times and the incidence of mist and fog will increase as we move through the month with even the first touches of frost possible towards the end of the month. Sunshine is likely to be above average overall.
October looks likely to be turning more Autumnal with the Atlantic carrying some ex-tropical storms across the Atlantic making for much windier weather than September with some very wet periods too. Rainfall will likely end up above average in the North and West and near to or slightly above in the SE where some drier spells are likely. The month as a whole will most likely see temperatures close to average for the time of year with some colder interludes towards the North where wintry showers could make their presence felt by the end of the month along with frost at night. Sunshine amounts will more likely be close to or below average for the month as a whole, especially in the North.
November looks like the month will be characterized as rather cold but rather drier with a lot of cold, anticyclonic weather developing through the month, Mist and fog could well become a common issue night and morning persisting all day in places towards the end of the month. Frosts will become quite common too, especially away from the foggy areas. Some short milder interludes are likely too through the month when strong winds from the SW could bring areas of rain across the UK from the Atlantic. Temperatures over the month as a while will be below average with normal rainfall achieved from the short wet spells and sunshine rather lower than average. The incidence of snow is unlikely in November this year in the South but will fall on Northern high ground at times in showers following behind the short rainier spells.
In Summary this Autumn looks like a typical Autumn with highly seasonal weather from each month that we in the UK would expect. Some warm summery days are likely regularly through September with some Autumnal gales and heavy rain take hold in October before November becomes quieter again with fog and frost the main weather issues. Early snowfall looks like being reserved for the North this year, probably resulting from cold polar air masses behind cold fronts in late October and November but I don't see any particularly notable snowy events occurring over the UK this side of Winter starting in December.
TEMPERATURES NEAR TO AVERAGES OVERALL
RAINFALL AMOUNTS NEAR TO OR SLIGHTLY ABOVE AVERAGE
SUNSHINE AMOUNTS CLOSE TO OR SLIGHTLY BELOW AVERAGE
FOG AND/OR FROST SLIGHTLY ABOVE AVERAGE
GALES SLIGHTLY BELOW AVERAGE OVERALL
My next seasonal Prediction will be released in mid November or shortly afterwards.
