The GFS 12z continues its cold and cyclonic theme.


Detail hard to pin down though from this range.

GEM,


Polar maritime air can deliver snow showers. Obviously there is not going to be a freeze up, but this is the best we can do at this time of year

A fair ole splash for some parts of the country that are usually among the driest areas in the next week. . The distribution of the rain is quite variable too.

Also showers are smoothed in time over 3 hours and made to look like persistent snow; this is something to bear in mind.


My advice is to use 0.25 degree charts on a European wide level. I'd also avoid netweather as their precip type chart viewer is badly coded (hint: GFS does NOT understand sleet; any GFS chart with sleet being shown on it is basically an advert saying: I haven't put enough time into making this chart!).


850s are of course okay but people abuse them so much by using some constant benchmark like the -6C line without taking into account any nuonce which is ridiculous given that on the dry air ahead of an ana warm front an 850hpa temp of 0C can support snow sometimes.

Agree WI. Little sign of much in the way of spring warmth again on this morning's output.

Generally cool though rather than wintry and also unsettled at times.

Morning all, the cool theme continues after the milder blip next week. I have not too much hope for snow in the reliable timeframe, Perhaps as we get into March it may change but in my mind it's too little too late again.

Ecm still tormenting us coldies with Jam tomorrow charts. Probably still just cold rain in he South though. Part of me wants to give up and look for Spring warmth now but there is little on show this morning.

Although the GFS at the same time has some nice Spring warmth.

The 564 line makes it to the Black Sea on the Fax charts; I always have a little spin when this line makes inroads into Europe/W Asia.

From a purely "scientific" point of view it will be interesting to see what effect the next warming stratospheric warming will have. This time it looks like a genuine major SSW (after the previous minor one). http://users.met.fu-berlin.de/~Aktuell/strat-www/wdiag/ts.php?plot=fluxes&alert=1&lng=eng 

Academic to an extent at this stage of winter but interesting nonetheless and not an overly good omen for a warm early spring.
