onfirmation of Actions TReC Case Selection Conference Conference time: 200311150900 Outlook: Beyond Thursday 20th there is growing agreemnt among deterministic models and NCEP and ECMWF ensembles for trough amplification in the sector from mid-Atlantic to western Europe, but with a grest deal of uncertainty in the detail and actual longitude. There is scope for an interesting case verifying around Friday 21st with the potential for strong cyclogenesis in the base or forward side of the trough. Existing cases : Identifier: TRec_013 verification region: Northern Europe sub region: 57N 00E verification time: 200311191200 (Wednesday) observation time: 200311181800 (Tuesday) priority: low actions: It looks very unlikely that there will be any interesting developemnts as the wave runs east across Scotland on Wednesday 19th. There remains a small chance of developing if the upper trough to the rear moves east fast enough to engage the wave, but sholud this happen it is likley to be a lst minute event and hopefully could be caught by targeting a short range forecast as suggested above. We are therefore not holding a conference this afternoon and there are no requests for any additional sensitive area calculations today or flights on Sunday or Monday. There will be no morning conference tomorrow and no afternoon conference unless notice is given on the ftp site or by e-mail before 1000UTC tomorrow (Sunday 16th). The next routine conference will be at 0900UTC Monday 17th.
