WVclimo Posted September 27, 2011 Share Posted September 27, 2011 Picked up 0.21" from the pre-dawn thunderstorm, and another 0.25" from the one that just rolled through. Up to 6.60" for the month. Just looked at my Cocorahs reports for September submitted at 7 a.m. each morning. Tomorrow will be the 20th of 28 reports this month with rain.

canderson Posted September 27, 2011 Share Posted September 27, 2011 Supposed to go the Orioles-Red Sox tonight - anyone have any model reports as to the chances of getting the game in? Last I saw, it didn't look promising for Baltimore ... Link to comment Share on other sites More sharing options...
Ian Posted September 27, 2011 Share Posted September 27, 2011 storms are weak but they are wanting to rotate and stay discrete. kinda interesting for now i guess tho seems like we'll not quite get there? south of fredericksburg actually looks decent for the timebeing.

Last I saw, it didn't look promising for Baltimore ... Please flip off the team for me. I'm thinking about heading up for tomorrow's game but its dependent on tonight's outcome - not sure I want to put myself through that kind of heartbreak! Have fun tonight..hopefully they get it in and the sox win. Link to comment Share on other sites More sharing options...

Ian Posted September 27, 2011 Share Posted September 27, 2011 Rotation still kinda messy but it's been there a while. I think the little blowups it's sucking in are fueling it a bit but also keeping it slightly disorganized. It's less and less in it's own environment too.

wxmeddler Posted September 27, 2011 Share Posted September 27, 2011 Using base velocity out of LWX, you can def see the green and red close by each other Remember though that KLWX 0.5° (lowest possible) is hitting ~3500 AGL down there. If you look at TDWR ADW the 0.3° beam angle hits at ~1500 ft AGL. But then consider the shortened wavelength that TDWR's have, and those downfalls at that distance. It's like a pick poison scenario.

Bob Chill Posted September 27, 2011 Share Posted September 27, 2011 The cells firing just to the NE of CHO are probably the only chance that DC metro and western burbs will have at getting into some action.

Ellinwood Posted September 28, 2011 Share Posted September 28, 2011 Not sure if today warrants its own severe thread, but wooooooooooo 5% TOR let's go chasin! (it's 5,5,5 for probabilities, where the 5 wind/hail are the same area as the 2% TOR) ...MID-ATLANTIC REGION... EWD TRANSLATION OF THE UPPER-LEVEL LOW WILL AID IN MODEST STRENGTHENING OF LOW-LEVEL S/SELYS RELATIVE TO TUE AHEAD OF A QUASI-STATIONARY N/S-ORIENTED FRONT ACROSS WRN PA/VA. THIS WILL EFFECTIVELY MAINTAIN RELATIVELY RICH BOUNDARY LAYER MOISTURE CHARACTERIZED BY SURFACE DEW POINTS IN THE MIDDLE 60S TO LOWER 70S. DIURNAL HEATING WILL BOOST MLCAPE TO AROUND 500-1500 J/KG AND WITH MODEST MID-LEVEL HEIGHT FALLS...SCATTERED TSTMS SHOULD FORM ALONG AND AHEAD THE FRONT THIS AFTERNOON. ALTHOUGH STRONG S/SWLY MID-LEVEL FLOW SHOULD LARGELY REMAIN CONFINED WEST OF THE FRONT...EFFECTIVE SHEAR WILL HOLD AROUND 25-35 KTS WHICH WOULD SUPPORT MARGINAL SUPERCELL STRUCTURES PRODUCING LOCALIZED DAMAGING WINDS/SEVERE HAIL. HOWEVER...WITH 0-1 KM SRH INCREASING TO AROUND 100-150 M2/S2...POTENTIAL FOR A TORNADO OR TWO SHOULD BE MAXIMIZED FROM PORTIONS OF CNTRL VA TO S-CNTRL PA.

BethesdaWX Posted September 28, 2011 Share Posted September 28, 2011 Maybe we score at Sunrise? A good squall line moving north with plentiful lightning & decent base velocity readings. Would really take down tons of leaves locally. Might be best to go with the usual whiff scenario. Link to comment Share on other sites More sharing options...
