coolio Posted August 7, 2020 Share Posted August 7, 2020 Pretty bad out in Leesburg. Worst part is that this front seems to be with us, maybe into Saturday morning. Thought it was gonna clear out by Friday afternoon. Seen this before here where a mass settles over an area and the sponge gets squeezed dumping water over an area. No wind just straight vertical rain. Link to comment Share on other sites More sharing options...

CAPE Posted August 7, 2020 Share Posted August 7, 2020 From Mt Holly AFD this morning- It looks like two primary rounds of convection remaining. The first opportunity is for the remainder of the overnight through mid morning today. This comes thanks to another convectively enhanced vorticity impulse riding up along the stalled frontal boundary. Radar overnight has been very unimpressive so far, as it was yesterday afternoon and evening. Strongly suspect that the unexpectedly vigorous MCS on Thursday morning really did a number on the atmosphere, and that we still have not recovered. Mesoanalysis indicates at least some modest amounts of elevated instability in place early this morning, and plentiful low level moisture with PWATs from 1.5 to 1.9 inches, highest to the south. Shear is weak, and storm motions are very slow from the southwest. So heavy rain remains the greatest concern through the morning. Quite a bit of uncertainty in how widespread this round of convection will be given concerns about the instability; so far it is struggling to get underway, but will wait awhile longer before cutting PoPs for the coming hours. Where storms do develop, flash flooding remains a possibility given the slow storm motions, possibility of training storms, and saturated ground. The second opportunity for convection comes this afternoon and evening, into the early overnight. This time, the trigger will be a combination of the approaching trough from the west as well as a little more energy streaming up from the southwest. The bolded part is interesting, That was intense(and unexpected) here, and it expanded/strengthened as it moved towards coastal NJ. 1 Link to comment Share on other sites More sharing options...

CAPE Posted August 7, 2020 Share Posted August 7, 2020 Excessive Rainfall discussion for the MA from WPC- Activity on Thursday was widespread and quasi-organized on larger scales. On Friday we may see lesser coverage and/or lesser longevity of individual storm clusters, as the upper trough continues to fill, experiencing height rises at its base over the Ohio Valley and mid Atlantic today. Sufficient heating of the still tropical airmass, however, is likely to lead to scattered initiation along sea breezes, over the mountains, and near a quasi-stationary front and inverted surface trough sitting over DE/MD/PA. Hi-res model consensus places the greatest concentration of rainfall over Maryland and southern PA to southern NJ, thus near and north of the surface front where both mid level and jet level forcing should contribute to somewhat greater lift compared to areas farther south. Models generally agree, and especially the various HRRR runs, that a flash flood threat could develop early in the morning as the tail end of a jet entrance region interacts with the CAPE gradient north of the front in Pennsylvania. Coverage of storms will then increase elsewhere by midday, with HREF odds of inch per hour rates peaking after 22Z in MD/DC/VA. The environment and model signal certainly support local rain rates nearing 2 inches per hour. Much of this region is quite saturated, to say the least, in the wake recent widespread heavy rain events. Once again, a lack of sustained forcing and the expectation of lesser coverage today is what keeps this event in the Slight Risk category, but wherever multi-inch rainfall occurs in urban areas or other sensitive basins, an isolated significant flash flood is possible.

Round Hill WX Posted August 7, 2020 Share Posted August 7, 2020 I ended up with 4.36" last night in Round Hill. There are some wild pics/video on SM this morning of true flash flooding in the area. Reinforces just how dangerous flash flooding is compared to other types of weather.... 5 Link to comment Share on other sites More sharing options...
