Analysis
Just what kind of feature is this?
Just what kind of feature is this? Answers on a postcard please. It would be so good if the UKMO released the SR (Synoptic Review) part two (if there still is such a bulletin) to answer …
Keep it simple
I don’t see how you can have dew points of 18°C and 19°C after the passage of a cold front, well to be exact the passage of an upper cold front inside a warm sector, then …
A simplified analysis
I don’t know if you like me long for the return to a more simplified analysis of the North Atlantic chart from the UKMO, rather than the nephanalysis that it’s turned into in recent years, replete …
Stratus not quite melting away as quickly as planned…
The low stratus didn’t just melt away as Stav Danaos suggested it would yesterday, it seems to be clinging to the higher dewpoint area that was across the same area on Friday, and probably connected to …

Upper cold front
I have my doubts about just how much of the intense rain in the weather radar crossing Scotland at the moment is actually reaching the ground. With the paucity of observing stations it’s impossible to verify …
The elusive quasi-stationary front makes a rare reappearance
I was only remarking in a recent post that the UKMO never seem to identify any quasi-stationary fronts these days on it’s analysis or forecast fax charts, so I was very surprised to see this morning …

Juliane a retrograde kind of low
My quite fanciful analysis of today’s 12 UTC chart but what the hell. It’s quite unusual that you get a retrograde kind of low like Juliane is forecast to be. Pressure is already falling quite nicely …
Whatever happened to the good old quasi-stationary front?
I was looking at the T+24 forecast chart from the UKMO this morning and it occurred to me that you rarely if ever see a quasi-stationary front on an analysis or forecast chart these days from …

Cold air pushes on south
The cold air that plunged down from the north yesterday across IONA is still pushing south today across central Europe with a lot of heavy rain across southern Germany that’s turning to snow over higher ground …
Cold front finally gets a wiggle on
I never really believed the forecast in the various models from earlier in the week regarding their forecast of today’s rain across the NW of Scotland, but it ultimately proved to be completely correct – isn’t …
12 UTC analysis 9 May 2020
Yet another miserable couple of days north of Inverness, although we do seem to have escaped the worst of the rain in Strathpeffer, and the sun has broken through a couple of times during the morning …
The ups and downs of MSLP since December 2019
This is a chart of surface pressure and anomalies since last December which I’ve gleaned from reanalysis data (for 55N 5W) includes peaks for the anticyclone of 1050 hPa that affected southern parts in mid January, …
April 2020 Analysis
You could almost use the midnight charts with an excessive number of fronts on them as a marker to when the Chief with a love of multiple warm sectors and occlusions was on shift. I can …
Last minute sex change for occluded front
After my emotional plea yesterday that the occlusion coming down across Scotland was in fact a cold front in disguise and never in reality been an occlusion at all, the Met Office had a change of …
How to identify a cold front passage
The cold front that’s now across the Moray Firth and moving quickly southward maybe not be a classic of it’s type, a low level feature with little upper or medium cloud on it, but it goes …
Cold front looks weak but isn’t
The surface cold front that’s now crossing the northwest of Scotland looks a pretty weak affair on the face of it, but it did produce a sharp drop in temperature and a burst of heavy rain …
The amazing stationary occlusion
Despite my earlier protestations that the occlusion the Met Office had drawn across Scotland in reality didn’t exist in their 06 UTC analysis when compared to the visible satellite imagery, undeterred the Great Oz confounded me …
So where exactly is this occlusion?
Where exactly did the occlusion that was supposedly over Inverness in the 06 UTC analysis go? It’s certainly not evident in the 0845 UTC satellite image, although the trough that’s following on behind looks to be …
Frontal analysis
I thought that I would just take a look back at the history of this pesky cold front that’s been quasi-stationary for much of the last five days over the northwest of Scotland and try and …
17 March 2020 – 15 UTC analysis
A flat warm front wave on the cold front running E’NE across Northern Ireland makes for an interesting plotted chart for 15 UTC today with a sharp temperature contrast north south across the UK. Looking forward …
