WX summary; band of below average temps from Spain to C Europe to N Russia still in place for week 1; warmer over Balkans but cooler over Finland week 2. Dry over Scandinavia week 1 with areas of rain all around and indeed stretching down to the Med week 1; drier on Atlantic week 2 and a narrower area of rain Spain - Alps - Finland. Wet for England week 1, damp for all Britain week 2
Jet - nothing much near UK until beginning of May when loops appear, quite strong but from random directions in the region of UK
GFS - trough extending S over UK nearly gets pinched out midweek, but revives as LP over Biscay 1000mb Fri 22nd which with HP 1035mb Iceland gives E-lies for all. This LP/HP system shuffles around a bit; by Fri 29th LP is 1015mb E France and HP is 1030 mb Rockall with winds turning to the NE, quite strong at times, and finally on Wed 4th LP is 995mb Czechia and HP 1025mb W of Ireland with N-lies esp on East Coast.
GEFS - mean temps near norm through to Wed 4th but some v cold outliers appearing near the end esp in NE. Small amounts of rain at any time, rather more in SW.
ECM - develops differently from GFS after Sun 24th as LP moves N from Biscay to England looking like a shallow showery trough but then converges with GFS again by Thu 28th, though the pressure gradient is not as steep and winds lighter.
P.S. Hat-trick; 3 days without reply!
