Ian Posted July 20, 2012 Share Posted July 20, 2012 Was looking for it earlier, doesn't NCDC or someone have a good weekly/monthly regional precip map? Would be interesting to see bullseye downtown. this? http://water.weather.gov/precip/ Link to comment Share on other sites More sharing options...
aldie 22 Posted July 20, 2012 Share Posted July 20, 2012 I've seen less than 6" of snow since 2/11/10. Waaaaaaaa! (that should do it) LWX ARW and NMM look pretty good today. HRRR is less impressive. NAM is pretty lame through 11 hrs. Mountains really eating up the incoming stuff from the West...precip totals will be light unless things blow up Link to comment Share on other sites More sharing options...
EastCoast NPZ Posted July 20, 2012 Share Posted July 20, 2012 Very pretty vort: https://public.blu.l...bookend bow.gif Ended up with 1.34" in Clarksburg. Nice, soaking 0.31" in 1h15m after the initial 1.03" in 16 minutes. I don't recall ever seeing such a thing before. What is the cause of one of these? Does it have an official name? Is it associated with any certain type of severe weather? Link to comment Share on other sites More sharing options...
MN Transplant Posted July 20, 2012 Share Posted July 20, 2012 09z LWX WRF-ARX is still stormy (below). 12z NAM keeps most of the precip south. HRRR might be the most realistic, bringing the batch of lighter precip from WV over the DC area mid-day, effectively killing off any instability, then having storms blow up over the Blue Ridge, but staying out there and south.

Is it associated with any certain type of severe weather? It's called a bookend vortex, discussed a little earlier in the thread. Vortices are created by the faster (relative) windsperd rear-inflow jet in a bow echo segment.

Ian Posted July 20, 2012 Share Posted July 20, 2012 The LWX FFW effectively killed our chances if we get storms/widesperad activity i could see it coming to pass flooding wise but im just not sure we'll get a lot of activity. getting midday showers isn't usually helpful for the stormiest scenario. i'll wait to see the 12z gfs before writing it off.

CranberryWX Posted July 20, 2012 Share Posted July 20, 2012 It's been rather cloudy and much cooler today, just in the low to mid 70s so far, but still very muggy. Thin line of storms approaching from the northwest extends all the way from Pittsburgh to Loiusville...must be the front. Link to comment Share on other sites More sharing options...
TUweathermanDD Posted July 20, 2012 Share Posted July 20, 2012 My report to AKQ as I'm in OCMD this week. From Thursday, July 19 (Spotter: BL021) Storm that hit Ocean City, MD which began around 2:45 through a cell which rapidly developed west of town in Berlin shortly priorat 2:30 The cell continuously underwent backbuilding and re-intensified, with the worst of the weather coming after 4:30 PM, where Special Weather Statements were issued. A friend of mine called in a report yesterday, and I can verify the damage report. There were hundreds of trash cans knocked over on the beach, and the cell brought trashcans from further away then the beach tossing them into the Ocean. The special weather statement added rotation was detected, and judging by the scattering of trash and even lifeguard chairs being knocked over an down into the waves, this storm displayed severe winds. Located near Marty's playland on Worcester street, the winds unexpectedly came in from the south and quickly exceeded 50mph, with gusts sustaining themselves. A handheld anemometer reading of 64mph was collected, and is at least partially supported by the 55mph gust at the NWS Ocean City Inlet station on wunderground. Damage photos will be sent in a supplemental e-mail, but this looked to be a either a gustnado, or a microburst. Either way, the storm was certainly deserving of a severe thunderstorm warning, but judging by radar signatures, I can see why one was maybe not issued. I sent pictures also, I've never seen so much trash on the beach, I also added to them: There were tents ripped apart, chairs broken, and wood sheared apart like in the final picture. I've never seen so much trash and debris laying around, but it is certainly sensible considering the beach rules that people must leave their belongings only to return for them once the beach is safe from storms.
