9/21-9/28 heavy rain obs

Current Meso analysis at H5 features an ejecting parcel from the overnight, with another close on its heels rounding the bottom of the trough. As that and a favorable R entrance region jet drag up PWAT of 1.6++" in an almost straight north direction (as indicated by the 850 mb moisture transport), it could of course be the best threat for heavy rain in the near - med range. http://www.spc.noaa.gov/exper/mesoanalysis/new/viewsector.php?sector=19&parm=pmsl#

I notice that the 3z SREFS still play this out as a mostly east of I-95 event - until 0z Sunday at which time it pokes a spoke of additional QPF back into C. PA. That notion of a late weekend soaking is well supported by the 0z SKEW-T.http://www.meteo.psu.edu/~gadomski/compskwframe0z.html

I gotta say though, the WV imagery is not at all impressive - the tap root is only just touching the GOM as Hillary steals the real moisture available from the deep tropics. Plus the approaching jet streak rounding the positively tillted trough is not exactly coming through a bastion of moisture. That is likely the difference between the firehose we could have seen, and the sprinkler with a "heavy" setting that I expect. http://weather.unisys.com/satellite/sat_wv.php?inv=0&t=l3&region=he

Long range outlooks feature a persistant Omega Block that fades and flexes through mid-Oct. So expect something a bit like this for the next couple o'weeks.
