  1. The GFS 18hrs run is another variation on the zonal theme, this time the Azores high is pushed east and puts the final nail in the coffin for European ski resorts which haven't been lucky with the recent snow.

    I thought it has been dumping in the Alps especially the French Alps. 30-50cm since Friday and some cover down to 1000m. However will it all melt if the Euro high returns?

  2. I've been watching the models dithering this week, trying to determine how the current blocked situation will develop. It's interesting to note the ECM keeps trying to retrogress the HP. For those looking for significant cold, there don't appear to be any strong indicators, although the pattern suggested by the ECM, if it persisted, with HP to the N or NW would certainly drag in some cold air from the NE.

    If you look at the current blocking pattern from an historical point of view, I cannot recall a situation where such a persistent HP as we have had over Europe all this time takes it upon itself to start retrogressing. Usually, any prolonged block of the kind where a NE flows develops over the UK often seems to occur when HP develops over or near the UK and then bullds to the NW (take a look at the classic January of 1881 to see this process working at its best!).

    All things considered, I would suggest that the GFS could possibly be right in the longer term, with the SW /W flow gradually displacing the Europe HP further S. However, I also suggest that the fact we have had this much blocking so far this autumn tends to favour its recurrence.

    We'll see!

    Not what I'd like to hear but I recognise the voice of experience here! :good:

  3. Just arrived in Coventry, after cycling from Edgbaston to Warwick, then Stoneleigh and Walsgrave. For the first hour of the ride, there was the very occasional frozen drizzle, then the second hour saw sporadic mixed graupel and snow. In the last hour (from Warwick onwards), the joy of seeing more sustained snow was tempered by the strengthening winds blowing the odd graupels in the face. In the last half-hour, I am looking at light to moderate snow whilst enjoying a well deserved lunch. No sign of snow settling yet.

    Snow? Today? Yowm 'avin a larf aint ya?

    No.

    Already 2cm+ wet snow reliably reported over some uplands of Glos. The WBFL is lower than initial NAE expectations and we modified forecasts this morning accordingly to bring the (transient) snow risk further southwards in the Midlands.

    Ian Fergusson on the midlands thread confirms snow in Glos. so transient snow is likely for most of the Midlands now. I guessed that would happen when the tenp overnight fell to 0c instead of the forecast 3c!

  5. well the weird thing is meto and all other radars have it vanishing aswell. maybe its not a glitch? anyone else under a place where it supposedly vanished got any update on whether its still snowing?

    We have had a steady but unexciting snowfall in the last 1 and half hours but the 20.00 and 20.15 radar pics showed the clouds near B'ham disappearing before reappearing at 20.30. Technical issue?cc_confused.gif
