The 12z ECM is enough for me.
**on 4th March, at T240, an anticyclone will be centred in the Atlantic to our west. It will produce a cool NW, or a cold northerly flow and temperatures in the UK will be generally below average. Snow is quite possible over the hills of northern Britain and there will be night frosts in many areas, if skies clear.** A cool start to March. |

Looking the same this morning, but the gfs does keep kicking out these very cold operationals, doesn't it? The 06z is a classic example. I don't think there's a chance of that being anywhere near the ensemble mean at 10 days. The ECM is where I think we'll be in 9 days. |

Certainly looking cool into March, but that gfs 00z is again a cold outlier. I wouldn't set store by the gfs operational at present, but the ECM has stayed closer to the ensemble mean and is probably the closest to what conditions will be at 10 days - an anticyclone will build toward us then retrogress, allowing a colder feed of air during the first week of March. |

its always a outlier when it doesnt fit your guess, sorry forecast.
fact is, it wasnt. On 24/02/2011 8:14 AM, Dawlish wrote: , but that gfs 00z is again a cold outlier.

Chances of some significant March cold can't be ruled out though. |

We'll be left with lots of sunny and mainly dry weather. Spring; albeit a coolish start. |
