I think the met got to get this one right because it will affect more people , unlike friday when it snowed in the night this is rush hour, more slack to be had if they get it wrong.

Still nothing forecast on the websites, it's now just 14-18 hours away what the hell! If the charts are right then people are going to have a shock tomorrow since no one really knows it's forecast to snow here. shok.gif

If they leave it at yellow then perhaps mo disagree's but if mo agree's then it would better for them to put out a amber warning and overestimate it than to underestimate it.

I think if they put out a amber waring it will be around half 4.

For me living in the south west of Wales, the 12z NAE is a big upgrade with us joining in the fun also tomorrow. Need future runs to back this up however. We will see.

Do you think this could be less marginal for coastal area's than last fridays event as things stand with the NAE at the moment?

still looks pretty marginal but less marginal for your area than Friday. So it depends on your location. Not sure on the 12z NAE as the precip is further west than previous runs however you would hope it is starting to get a better idea now considering its tomorrow.

Sleet in Bridgend need to get the dewpoints down a little I fear this does not bode well for coastal areas later when humidity rizes with oncomming fromts

2 gegrees here with dewpoint at 0.5 giving wet sleet

GFS plays it diferently with snow right thru till Thursday. So models struggling with how this will evolve in under 18 hours.

I think it will be now casting but the met office will look at outputs from all models and try to find areas consistantly being forecast to be at risk, put them on Amber and areas that models are on their own for, on yellow Alert. It really is one of those situations. I think somewhere will have a pasting and late on someone will get a red warning a second in under a week.

Some decent showers building to the south should reach S Wales soon.

The dew point has been all over the place today as in the last hour is gone from 0.5 down to -1.5 and then back up to the current reading 0.9. As someone mentioned the wind is a westerly and it must be dragging in less cold air.

Looks a lot more marginal to me than Fridays event as temps and dewpoints were dropping all the time, this time, dew points are likely to rise, even on higher ground, and there will be sleet/rai. On extreme coasts.

Snow in the Bristol channel moving west should be here by 5pm, with temps at 2C and starting to drop and dew point at -0.5 (humidity at 83%) hopefully it will fall as snow when it gets here!

Interesting from the UKMO, for 60hrs right up to 72hrs, it shows some quite heavy precipitation falling across Wales, with -5/-8C uppers and the flow coming in from the continent dew points would probably be in the negative figures for most of the UK, with these all combined, snow could be on the agenda again, it is 3 days away but just showing how snow can seemingly pop out of nowhere!
