oups.com... Are we going to get any storm action in the SE as was being mooted friday?..... someone was waffling on about a 'spanish plume' A risk for NE England and East Anglia later this afternoon, otherwise the main developments appear to be over the SW this evening, then more generally in the west overnight with the activity transferring east later tomorrow.

There's a thunder risk for NE England today. This morning skies see to
bear this out. There was a lurid red sunrise here this morning and the skies are full of accas and is that strange yellow colour. The GFS 06z run is showing LI -4 and CAPE in hundreds / thousands in a line stretching from Oxford to NE England. A day to watch. les keith w wrote: Are we going to get any storm action in the SE as was being mooted friday?..... someone was waffling on about a 'spanish plume' -- Les Crossan, Wallsend, Tyne & Wear 54.95N 1.5W Home of the Wallsend StormCam and the Backup USW FAQ - www.uksevereweather.org.uk |

Can anyone give an explanation as to what the Lifted Index and CAPE signify?
I've looked at the FAQ and I can't seem to find it. Or have I just not looked hard enough?? -- Rob Overfield Hull http://talkingtoomuchagain.blogspot.com Les Crossan wrote: There's a thunder risk for NE England today.

All you wanted to know about CAPE but were too afraid to ask!
Off Martin's website.... http://homepage.ntlworld.com/booty.w...opics.htm#CAPE Keep your camera handy Rob you're lucky to have all that flat ground there  les Rob wrote: Can anyone give an explanation as to what the Lifted Index and CAPE signify?

Thanks Les, I wasn't expecting a response so fast! Now I get what its about,
but I like the proviso that the thresholds are calculated from US situations, sometimes I think we follow it too slavishly in Europe. As for this next couple of day, well I live almost in the middle of Hull! Not very flat with all the houses, but I shall be keeping my eyes well peeled for the next 36 hours to see what heppens. If it happens, I'll log it! -- Rob Overfield Hull http://talkingtoomuchagain.blogspot.com Les Crossan wrote: All you wanted to know about CAPE but were too afraid to ask!

Best way to find such is to use .... http://homepage.ntlworld.com/booty.weather/uswfaqfr.htm and then choose either the "Site Search", or "Detailed Index" options. Not all the topics are within the FAQ document itself, but have, over the years, been added as 'daughter' documents.

The presence of high CAPE does not mean in itself that severe storms are likely but that if they do occur they may well be severe. The mechanism that triggers the release of the energy is the really difficult thing to forecast and involves subtle things like convergence lines. Tudor Hughes, Warlingham, Surrey. |

keith w writes Are we going to get any storm action in the SE as was being mooted friday?..... someone was waffling on about a 'spanish plume' Can't speak for the SE, but we had some here in Cheltenham this morning. Several cells moved through, producing 6.9mm of rain. -- Paul Hyett (change 'invalid83261' to 'blueyonder' to email me) |
