EC week 2 forecast relents wave 1 forcing a little during week 2, but really ramps it up again during weeks 3 and 4 with a very coherent N.Pacific pattern for displacement to continue..... Volgens Stewart, gebaseerd op EC32, ik heb deze hieronder geplaatst. Let wel, zijn opmerking betreft dus het kanon op de juiste plek te zetten, zodat de beschieting (wave) van het fort (vortex) kan beginnen.
A brief overview of the latest EC32 update
The anomaly on the 13th LP Alaska, with ridge into GOA, and SW US with HP NE Canada, A trough NE Atlantic and eastern Europe. So mostly unsettled but tending towards a N/S split.
The next week up the 20th initially brings an intensification of the trough in the eastern Atlantic bringing some very unsettled weather to all before settling down to a slightly quieter zonal flow.
This theme continues but signs of some ridging from the south west/ south east around the 24th – 28th so more settled conditions, certainly in the south with temps a little above average.
After this there is a tendency for the trough to the NW to move east accompanied by slight pressure rises to the west.
Summary
A flow from the westerly quadrant for the whole of the period which will bring periods of very unsettled weather as systems move in from the Atlantic. Quite wintry in the north with some snow and strong winds. The latter could even affect the south at times. This though interspersed with more settled periods particularly in the south. Temps will vary quite a bit around the mean as systems move through and with the interplay of the Pm and Tm air.
Keep in mind this is not taken from the full suite output so some nuances will be missed although broadly speaking it wont be far from the money.
I should have added that the control at the end of the run has strong ridging to the west and a trough to the east.
-> Volgens EC32 dus voorlopig geen winterweer. Wel is de setting gunstig voor wave 1 (zie laag bij de Aleoeten)
