The Feb 10-12 storm threat, real or imagined?

yea I got educated , thanks. Control FTW? lOl

http://mathsci.ucd.i...s/ECMWF-EPS.pdf

ECMWF Ensemble Prediction Systemconsists of one control forecast startingfrom the best guess initial conditions,and 50 members starting from slightlyperturbed initial conditions. The leftpanels show the initial mean sea levelpressure for the control run starting on22 January 2009 (top left) and for oneof the ensemble members (bottom left).The differences between these startingconditions are hardly visible. However,these similar initial conditions produceforecasts that are very different after only48 hours forecast time

Ah yeah there ya go....says it much better than I did. :lol:

On the euro there might actually be BL issues for a decent sized chunk of SNE....doesn't necessarily mean much right now but that's something to keep in mind going forward.

How sucky is it that the first week of Feb we have BL issues from high SSts with a circulation like this. Like you said early but can you imagine, geezus

East of the ct river would have issues on that map, perhaps even in the hillier terrain, west is best no marine taint.

The marine taint only goes back as far west of 495.....it's pretty apparent on the map that Steve posted that there is ageostrophic flow to the west of that line.

The CT River valley still may have issues because the airmass blows, but the hills west of 495 would be fine.

I'm not sure what map that is but the maps I'm looking at during the actual storm have the 32F line from about Ray to BDL and the 35F isotherm is way down in SE MA and central/S RI. SW CT to the cape is torching though.

looks like the hillier terrain would be fine on that run...maybe right even into BOS.

euro has the 925 0C line running from like DXR NE to PVD up to just south of BOS with SE flow so that always just makes me think BL issues for a sizable area of the CP.

but like scooter was saying...5 days out so whatever.

regardless...point in earlier post wasn't to imply rain...just something to keep in the back of our minds with that set-up mid to late week as it's not ideal if something comes along in the flow.

Well def south of a HFD to BOS line would probably have issues...but like where Ray is would be totally fine and most of metro west BOS and probably north suburbs of PVD and up 95 toward BOS....probably a wet snow there, but I'd think snow. The flow is actually turning more ENE by 132h as the low starts to bomb a bit.

But yeah...details at 132 :weenie:

Yea details at 132, solid 850's below to the coast and with the 925s as Phil described not bad. Hope it holds and the Euros warm BL bias is in play.

yeah i hate even digging down into anything at this time frame. it's just so boring right now it's hard not too start looking at these things in greater detail...it's a sickness.
