nw baltimore wx Posted July 28, 2017 Share Posted July 28, 2017 Man, I know everyone is rooting for a big time event, but I hope Ellicott City and the Woodberry section of Bmore are spared this time around. Link to comment Share on other sites More sharing options...

yoda Posted July 28, 2017 Share Posted July 28, 2017 Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 1123 AM EDT Fri Jul 28 2017 .NEAR TERM /THROUGH TONIGHT/... We are already issuing FFW`s just west of Washington DC. Radar estimates up to 3" of rain in an hour in eastern Montgomery County. The 12Z IAD sounding had a PWAT of 1.77" and that should continue to increase this afternoon. We are hearing reports of water rescues. See the Mesoscale Precip Discussion that WPC issued at 1040 am - excellent discussion of the meteorology expected for this afternoon and evening. I remain most worried about northern VA up to the PA border - as I`ve seen in writing this does appear to bear some similarity to Nor`easters and makes me think of some of the bigger snowfalls I`ve seen here where the CHO area might get 8" and central MD/eastern WV over 20" - as the low pivots off the coast snow will cease in the central Shen Valley but a band will hang on for many hours from Balt and westward. Obviously we`re not talking snow here but believe the rain will hang on through midday Sat across the aforementioned region. {...} Coverage expected to increase by afternoon, with the heaviest rainfall expected from late afternoon into the overnight as the surface low rides crosses the area as it traverses the frontal boundary.

yoda Posted July 28, 2017 Share Posted July 28, 2017 Oh @Kmlwx and @WxWatcher007 check out this last paragraph from LWX morning update to their AFD... Quote While Hydro issues are the primary threat today...some severe thunderstorm potential does exist...with a Marginal risk from SPC. The primary threat is isolated strong wind gusts due to modest instability and relatively strong shear profiles. While we are nopt outlooked for a tornado threat we feel spin ups could be a concern given low level helicity this evening. This is not in a normal quandrant on the hodograph given the easterly flow but still bears watching. Link to comment Share on other sites More sharing options...
