wxmeddler Posted January 17, 2013 Share Posted January 17, 2013 I'm actually getting slightly encouraged by the radar trends. Just did a cross section (more of a PPI) from LWX across DC to down towards Wes's house and beyond. zdr shows multiple seeder feeder dentritic growth bands in the range from 21kft down to 12 kft and precipitation making it down to 7000ft, which is knocking on the door of the dry air layer at ~850mb.

mitchnick Posted January 17, 2013 Share Posted January 17, 2013 sky across Shenandoah Valley to the south (left side of pic) is starting to become obscured so snow is starting to make its way to the ground to our WEST http://www.nps.gov/webcams-shen/pinnacles.jpg Link to comment Share on other sites More sharing options...

eurojosh Posted January 17, 2013 Share Posted January 17, 2013 that's gone up from nothing I think if we're going to have any last minute trends, this is the way to go because it means there's a greater <weenie> chance that it ends up more vs. a drier trend True - given that it's quite hard to go from nothing down...

Bob Chill Posted January 17, 2013 Share Posted January 17, 2013 I'm down to 39.1 now. Been a slow and steady fall all afternoon. IF I get precip I think I can get down to 34ish. Not so sure about 32. Kinda doubtful. Link to comment Share on other sites More sharing options...

SomeguyfromTakomaPark Posted January 17, 2013 Share Posted January 17, 2013 Looks like the precip wants to fill in near DC. Maybe by dark we can fall into the 30's and get some precip. Link to comment Share on other sites More sharing options...

J.Mike Posted January 17, 2013 Share Posted January 17, 2013 The folks at WJLA are feeling the love Faulty guidance and poor forecasting methods led to much of the hype surrounding the snow “storm” that would “hit” Washington. We passed along the WINTER STORM WATCH. We did not issue it. This was never going to be a major impact event and we have been playing down and throttling back the scope and impact since yesterday afternoon. Snow and sleet may develop this evening as colder air is entrained into two low pressure centers moving across the GA and SC. Very little impact is expected across the metro area and virtually no impact expected through the northern listening areas. Within and south of the ADVISORY areas, snow and sleet accumulations are still quite possible. Accumulations in the metropolitan Washington area will be less than an inch.

weathervswife Posted January 17, 2013 Share Posted January 17, 2013 OK, we've gone from slushy rain to very very wet snowflakes. The difference being the raindrops are not as aerodynamic. Link to comment Share on other sites More sharing options...

Ian Posted January 17, 2013 Share Posted January 17, 2013 The folks at WJLA are feeling the love kinda totally disagree with their first sentence. LWX made a call based on how they thought models were moving. they were wrong.. but they didn't just regurgitate guidance and actually did some forecasting. hopefully we stop beating a dead horse soon.

Deck Pic Posted January 17, 2013 Share Posted January 17, 2013 the delay in onset will probably help drop temps to the 35-37 range in the 1st hour of precip vs 37-39 ..FWIW Link to comment Share on other sites More sharing options...

snowfan Posted January 17, 2013 Share Posted January 17, 2013 I see everyone has their weenie 3D glasses on. Mine shows the large area of precip further to the SW being squashed ESE. Link to comment Share on other sites More sharing options...
