At first I didn't believe it but the rain gauge is reading 1.85 in the past 35-40 minutes. I checked a couple local weather stations on Weather Underground and they are reading 1.84, 2.0, etc. WOW! Still pouring across the Pataspco from you. Link to comment Share on other sites More sharing options...

87storms Posted July 28, 2017 Share Posted July 28, 2017 this is the point where analysis/paralysis sets in. i'm gonna just sit back and enjoy the fact that i can have the screen door open and listen to rain that lasts for more than the typical 10 minute backyard summer shower. rain in warm weather > rain in cold weather.

Bob Chill Posted July 28, 2017 Share Posted July 28, 2017 DCA may rack up and inch+ over the next hour. So far, the waves of rain have expanded and intensified as they drift north. The one approaching DC will probably do the same. Link to comment Share on other sites More sharing options...

Kmlwx Posted July 28, 2017 Share Posted July 28, 2017 Very cool radar watching today. Let's see what this next line does as it drifts north. Have been in the lull here in Potomac/Rockville - saw some peaks of sun too. Link to comment Share on other sites More sharing options...
Eskimo Joe Posted July 28, 2017 Share Posted July 28, 2017 Updated LWX AFD: Quote We have launched an 18Z balloon. Flash flood watch area remains in effect into Saturday afternoon. Coverage expected to increase tonight with the heaviest rainfall as the upper low moves across the forecast area and the surface low moves over the Delmarva. A storm total of 2-4+ inches is possible on average over the watch area. Although FFA extends to Greene County I remain most worried about northern VA up to the PA border - as I've seen in writings 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 20-25." 12Z Euro shows rapid deepening of the low tonight as it moves over the Delmarva and strong northeastly flow pushes moisture into the northern part the forecast area. Given the rainfall that north DC/Montgomery Co. have already received with several inches more possible tonight this will bear close watching. While hydro issues are the primary threat...some severe thunderstorm potential does exist...with area places in a marginal risk from SPC. The primary threat is isolated strong wind gusts due to modest instability and relatively strong shear profiles. East of I-95 has been placed in a 2% 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.
