Looking good for team wales today / this eve- Have fun !!

Dyma rai o'm lluniau gaeafol (Dydd Mawrth - Wythnos diwethaf) Here are some of my wintry scenes from Tuesday, last week Lleoliad/ Location: Blaenau Clwyd 230masl  (Between Corwen and Rhuthun)

Some photos from this morning up on the Rhigos between Hirwaun and Treherbert. Here we are around 480-500m asl  it was stunning with amazing views over the Brecon Beacons and beyond. The mountain

I am using a app called ventusky and i paid the subscription of only 79p a month so you can see the snow maps '

You can go forward and i went forward to tomorrow and its showing a decent snowfall from 11am until 1500pm then again from 1600 until 1800pm .

Just fingers crossed it is right .

Everything tomorrow is moving in the right direction in favour South Wales for sure. Superb event in progress. The sheer marginality for so many down here adds to the thrill of the chase. Beacons and mid Wales buried?

Temp 2.5C and slowly rising probably as the colder air starts to mix out as the front approaches? Meto forecast shows rain up until around 5pm tomorrow when its forecast to get colder and turn to snow, which would fall inline with the back edge snow as it wraps back around?

It's showing 1.5 C outside now and with our little bit of elevation I am hoping to see some snow tonight after all.  The rain has reached Haverfordwest and Milford Haven but the temps there range from 3-5 C - hopefully as the air temperature drops this will turn to snow by the time it reaches me!  Anyway there should be snow falling over large areas of west Wales tonight - who would have thought we would be saying that even four weeks ago.  Maybe this bodes well for midwinter - January is the most likely month to bring prolonged cold.....  We shall have to wait and see.

Okay guys

remember the front crossing into West country now is a warm front

It becomes Occluded around the time it catches  us , I believe even with the warm front there has been some sleet on hills. 

Now also if we are lucky the centre of the low will be below the Bristol channel, winds around the Northern side coming from the east, As it passes through we want to see the centre of the low intensify, so we get a circle in the Oval shape dragging winds around from Nw  ( all around from the East) behind it. 

The low could actually be centred just on shore as winds run into the low so even if we are in the circle around the edges air will be moving anticlockwise and inwards.

I think Places like Cardiff will see early wet snow, followed by sleet and rain before more snow later tomorrow.

However any lying snow helps to modify temperatures. 

Heavier precipitation assists where temperatures are marginal with evaporative cooling

However this is really only enough on its own to turn sleet to Snow or rain to sleet , where each droplet moves a parcel of cooler air towards the lower atmosphere and ground

hey all good luck all, i think mid wales , Valleys  and Welsh borders will get a hammering - lucky sods but i would be surprised if by end of tomorrow North cardiff does not have 2CM or more

Will it depend on elevation again Andy? 

 

not necessarily especially as we end up on the left hand side of the low and winds and temps dive back down - but it'll be interesting to see where the major totals end up - it's gonna be somewhere in Wales i'm sure
