  1. I think I may interpret the above as the 'start ' of this seasons melt. I can see a 'flat line' section as the peripheral ice drifted outwards and now we appear to be losing extent.

    C.T. are a few days behind the AMSRE in their data and still show all the 'closed ' sea areas at max extent but Bering is showing a growth spurt. I would imagine that this is Bering starting to fragment and drift out into the ocean yet still satisfying the '15%' coverage (so is shown as extent 'growth') as it drifts outwards.

    In a few weeks I would expect we will see Bering undergo rapid ice loss as these 'free' chunks drift further apart and we loose the '15%' coverage. For me it will be interesting to see what happens behind the Bering straights as this occurs.

    The sea ice extent appears to have increased over the last 3 days as shown below

    Would this be due to the breaking up of the pack, or the very cold air over the Bering and Greenland/Barents seas forming new ice? Probably the latter I feel. This pattern is however allowing some very mild air into the Hudson bay area, but it doesn't look like persisting.

  2. I think after next weeks unsettled weather the month will be fairly dry again in the south, but further north it may remain changeable. I think the moth will be certainly above average in terms of temperatures, but nothing like July. I would say 17.0ºc

  3. I'm going to go for 14.8ºc. I think the month will hold some half attempts to drag warm air up, but the jet may be too strong to allow a full on scorcher so i don't think we will match the heat of last June.

  4. Not sure where to put this so i thought i would start a new topic

    October 2nd half: It seems likely that cold air will move into scotland and northern england this weekend as the greenland HP tries to build southwards. I would expect several air frosts here and showers particually down the east coast, snow above 300 metres in scotland (possably lower). The south the cold air is unlikely to arrive due to the lack of pressure gradient, howether sunday night may well be cold.

    As the new week begins rising pressure over the near continent and a low centred out in the atlantic will sweep a south westerly flow of air across the UK. Expect warm and sunny, but a bit windy weather in the south and east, but the the north west will likely see rain and near gale force winds.

    As the week progresses the atlantic should fire up and begin to fir active depressions towards the UK, howether conditions will be mild due to the persistance of the high to our south east, preventing north westerly winds. I expect this setup to persist for the remaider of the month.

    November should start cooler as pressure to our west rises giving a northwesterly flow of air. This HP may well move to be centred to our northwest giving cool but not particually cold northerlies due to being too close to the HP centre.

    With pressure still fairly high to our south east i can only see this high retreating eastwards and linking up with this high to once again bathe us in mild southerly winds. This may well persist until mid month.

    By mid month pressure should start to fall to our south east and east, and also rise significantly across Greenland which will cause the first southerly tracking lows of the autumn. Expect some decent northerly blasts on the back of LP's.

    Towards the end of November cold air will be transfering east from greenland, and pressure will be falling there. Full power LP's will be smashing into the UK at this time bringing significant rain and wind. November CET 1.3 Above Average.

    Beginning of December, cold block building across siberia in an HP. The UK will be mild as will much of europe with a general south westerly flow.

    Mid december, Siberaian high moving into Scandi. Central Europe freezes in easterly winds while the cold/mild battle is situated to the east of the UK. As we head towards the 20th low pressure will sat to the south of the UK opening the door for the cold air to pile eastwards. South of England will be coldest with LP near by and possably a warm front trying to invade which may give a white christmas here. The north may be less cold due to the rather thin HP which will begin to turn things mild across northern Norway and Sweden.

    As the month closes the cold source will die as it is cut off and temps will begin to rise. December CET- About Average

    Jan and Feb may well see a lot more from the east, with a negative NAO...
