Still potential for huge soakers, but the weaker steering currents argue against widespread coverage. The weekend could be a different story, with a very favorable upper pattern and tropical moisture still in place. 1 Link to comment Share on other sites More sharing options...

yoda Posted August 13, 2020 Share Posted August 13, 2020 Never heard of WOFs before... anyone else heard of it before? What kind of model ensemble is it? Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 946 PM EDT Wed Aug 12 2020 .SYNOPSIS... A front will stall over the Middle Atlantic through Thursday, then drift southward Friday into Saturday. The front will then lift back northward through the end of the weekend as low pressure lifts into the Ohio River Valley. && .NEAR TERM /THROUGH THURSDAY/... The heaviest rain has tapered off for the majority of our region. A line of thunderstorms have formed over western Maryland and the eastern Panhandle of WV. The WOFs or Warn on forecast experimental ensembles were hinting at this solution all night and this will remain the main concern area over the next few ours. A new thunderstorm has also formed over central Virginia in Orange County and if it happens to move over areas that received a lot of rainfall in our central Virginia counties , further flood warnings may be needed. Since we have ongoing storms that may linger through the next few hours we may need extend the Flash Flood Watch through the overnight periods.

What kind of model ensemble is it? https://wof.nssl.noaa.gov It's a hi-res ensemble, effectively run on-demand. You select a regional domain of interest and initialize it with new assimilation techniques to try to get the best initial conditions (environmental parameters and ongoing precipitation). The longer term goal is to have a system like this be good enough so that warnings can actually be issued by forecasts from the WoF instead of having to wait for radar signatures or ground truth. 3 1 Link to comment Share on other sites More sharing options...
