WX summary repeats yesterday's charts: for Britain the really hot weather is now week 2 and only for England SE of Exeter-York while N Scotland along with most of Scandinavia and (later on) W Russia remains cool. Rain now pushed north, to N Scotland and N Scandinavia and (week 2) N Russia while the extremely dry area settles over the Channel, extending E-wards to Baltic and Ukraine week 2. If anything the hot area and the dry area affecting the UK have shrunk a little.
Jet - bits and pieces of the jet around the UK this week; then nothing until about Tue 17th when a W-ly flow appears.
GFS - current trough system moving away slowly NE and replaced by HP 1030mb SW of Ireland Sun 7th (deferred from yesterday's chart) This transforms into SW-NE ridge until Fri 10th when LP moves in first from the S then on Tue 16th from the NW, but HP back from the Azores on Fri 19th.
GEFS - from cool Sat 6th rising to warm/v. warm Sat 13th (op & control more bullish than mean; earlier in N ) after which lots of disagreement; the mean is back to norm by Fri 19th but so much divergence that result v uncertain. Some rain even in the S after Sat 13th, more in N
ECM - after Fri 10th it's not so much a matter of LP moving in as HP withdrawing to the Atlantic - pressure still fairly high but winds go round to the NW
