10 hours ago, Cold Winter Night said:
Taken at face value, the weather with this chart would be very cloudy, rainy and chilly. Not much wind though (isobars far apart). Unpleasant weather for most still.
There would be some discussion in here about what the heights near Scandi will do, if they increase, they could move the cold West.
The Greenland High is retreating and will not help much, but the jet and the train of lows that accompany it are on a very Southerly trajectory, so it will remain on the colder side, rather than milder. Technically not a West-based negative NAO, but the effect is the same.However, this is so far in FI, you might as well take out your own crayons to create a nice looking chart and it would be equally likely to become reality.
If you want to learn how to "read" the developments, look at closer timeframes, in the Northern hemisphere view mode.
Look at how Highs and Lows interact, look at other charts, like the 850 hPa temperature charts, the jet stream chart to see how the flow is tilted in a direction that either promotes blocking (buckling jet) or a flatter, zonal pattern (high speed, straight jet stream).
Then try to predict what every next frame will look like and see where you were right or wrong.Thank you CWN, that was a really useful post about model watching/interpretations

I didn't think it was going to happen
Now we have snow falling and settling, I hope more falls for a bit longer into the night. It looks as though the back edge isn't too far off the coast now.
-
Alternating snow and rain on the top of Portland matching the intensity.

Liking what I have seen this morning. Expecting PPN here inside the next hour. Sure it will be rain on landfall but as it wraps, fingers crossed, the changing wind direction and dew points should increase snow potential for later on.
Going to stick my neck out and say, even for Weymouth, we will be unlucky not to have 2-3 cm laying snow before tomorrow morning. Knife edge still.
Choose a good day to be working from home that's for sure!
I think it will def be knife edge for us on the coast, sat watching the radar and waiting to see what arrives and how/if it develops on the top of Portland.

It will probably be just rain/sleet today across the SW but it looks like tonight there will be some decent snow showers around on the NW flow. Even us in Weymouth/West Dorset tend to pick up the odd shower in that setup.
-
I thought we were all done here and was expecting rain (as showing on the ppn radar)....but we have snow falling again on Portland.
-
Light snow again on the top of Portland.
-
Freezing rain overnight on the top of Portland. Everything is sheet ice. Roads, paths, walls, front door, side of house....I've never seen anything like it before. Lethal but extraordinary to see.

Portland i reckon!
It is snowing lightly here now.

It's been snowing on the top of Portland for the past hour or so.
-
We have a dusting here in Weymouth.
-
It has been snowing lightly in Weymouth most of the afternoon.
Weymouth, snow and April are words not usually used in the same sentence!
-
Light snow in Weymouth.
2.7c temp, 1.8 dp

Early afternoon in almost mid March with icicles hanging from shed roof,,,,,,,,,,,,,Didn't have that in mid winter,,
Still light snow here in Weymouth. I also had icicles - hanging off the underside of the car this morning.....can't complain at that for mid March on the south coast!

The rain has just turned to snow here in Weymouth

I know some would be horrified by the amount of snow fallen so far this winter in my back garden (solely on Friday just gone) but that's more than I get most winters, so no complaints from me, a good few cm of snow in any winter is a result down here! (sorry to Weymouthonians living near the harbour, I know it was a different story there)
It does seem that we will have to go through the pain to get the gain. A 5-7 day(ish) milder interlude seems almost inevitable though as the trop vortex on the western side decays and energy looks to track east, thereafter I suspect things are going to look a lot rosier.
GP has posted his thoughts on the Tech thread. Looks good going into Feb. Very much along with my thoughts in that when HLB shows on the chart output it's likely to pop up out of nowhere. Happy days.
Talk about marginal on Friday.....it was snowing on Boot Hill and settling yet along Westwey Road yards away along the inner harbour it was only rain before turning back to settling snow when past the Southill roundabout. Very odd.
Hopefully we will have several more interesting weeks ahead before the winter ends :-)
-
Certainly pepped up in the past half hour, small flakes and very wet stuff though. Difficult with no light to see if it's more sleet than snow but it does look that way. No complaints though as the back garden is sat under a very healthy white blanket right now
We have a thin slushy covering here just up from the harbour, it looks more like a heavy hoar frost.....but at least the kids can say they saw some snow when they wake up! :-)
-
Does anyone remember when the south coast central area got the Red Warning a few years back? Does anyone remember the circumstances around that, and why it was predicted to be so bad? (albeit it was downgraded to an amber within an hour or so)
I remember it well. A red alert was issued about lunchtime, all the media outlets flocked to mid-Dorset for the snow-fest and were broadcasting by mid-afternoon.......2 hours later the red alert was moved 50 miles up the coast to Hampshire who got all the snow.
-
I would especially like to hear the reports from the South Coast and any subsequent Dewpoint readings and lamp-post reports are always welcome.
Weymouth 5.7c air, 2.5c DP
-
Wind is still Southwesterly here on the Dorset coast.
Here's hoping for a more southeasterly influence as the front approaches.
Umbrellas or snowboots?
I'm thinking more umbrellas at the moment for us Kevvo :-0
-
All i will do now is hope and pray that i see reports of snow falling at Weymouth and Bridport as the front approaches...if i'm up in time.
I'm fairly skeptical about the forecast here in Weymouth. We have not been anywhere near zero in either air temp of dew point this week and I can't see enough of a drop happening when it arrives for snow to reach sea level. It is currently 6.8c air and 1.9c dew point.
-
Anyone have a temperatures for around the region?
BBC going for 7 in Devon. Anyone approaching 5?
4.2 here in Weymouth
-
Currently +2.5c air and +1.8c dew point......no chance of any snow here in Weymouth by the looks of it!

We've had some light snow falling on the top of Portland in the last half an hour.
