Interesting the latest Euro for next Sunday tries to establish a semblance of a banana high with a coastal resulting in only 30s for highs n+w and some wet flakes even in northern Md . Gfs in contrast maintains some strong energy to the west northwest . I'm sure details will change being 7 days out but a coastal is looking more and more possible next weekend. Hopefully the beginning of many coastals this season

Giving us good practice for coastal tracking this winter. ❄️

Day 6/7 need to be watched for our first chance at a trackable storm for the Western burbs, and maybe a 'first-flakes' thing for others as well. There is a signal and EPS members jumped on board a little at 12z. Nothing to hype up but something I'll be watching carefully, especially given that I now live closer to the western burbs. ^_^

Euro verbatim would be fun Saturday evening. Heavy rain with temps west of 95 low to mid 40s with wind gusts over 50 mph 

CMC never fails to impress...has a 967 low over @C.A.P.E. house.  High elevation snows and 2-4" of rain over the region....gale/storm force winds.  Will be fun to track the first coastal of the season!

GEFS getting onboard... surprised less chatter, even though I realize odds are stacked.

LWX now including that 4-letter word in their Saturday/Sunday forecast.

(snip)Friday into Saturday, the upper level ridge to the north will
start to break down as a upper level trough builds into the
Tennessee River Valley and the Smokey Mountains. A broad upper
level trough will be positioned over eastern Canada and northern
Maine. The upper level trough over Tennessee and Kentucky is
forecast to broaden and expand further southward into
Mississippi and Alabama. This will lead to a tapping of the warm
and moist air from the Gulf Mexico. The models are pointing to
a low pressure system forming over the Gulf of Mexico on
Thursday and moving east to northeastward toward Florida and
Georgia early on Friday. This low pressure system is expected to
get caught up on the east side of the upper level trough and
move northward along the eastern sea board. Both the 00Z GFS and
Euro agree that a coastal storm will form and move northward
along the east coast. The GFS takes the upper level trough and
kicks it eastward forcing the coastal storm further off the
coast while the Euro keep the trough further inland over
Arkansas and Tennessee. The Euro is wetter and faster than the
GFS. The Euro brings the coastal storm northward and moves
precipitation into our region by 18Z (2pm) on Friday. The GFS
brings the outer bands of precipitation into the region around
6Z (2am) Saturday morning and remains further off the coast
leading to lesser rain event. Both models agree that some
semblances of precipitation will likely occur on Saturday with
there being a chance for precipitation starting sometime late
Friday afternoon into evening. The 1000 to 500mb thicknesses
seem to indicate that this weather event should be mainly a rain
event with some snow potential late Saturday into Sunday for
the higher elevation areas. A slight warm up will occur Friday
into Saturday as winds become more southerly.

Sunday, the coastal storm will shift further northeastward out of
our area. Some lingerings rain and snow showers over the higher
elevations will be possible on Sunday. The GFS tries to bring a
secondary cold front Sunday afternoon while the Euro tries to keep
this boundary mainly dry.(snip)
