Yep, we're really taking a hit with this one. Up to 3.05 for this afternoon. Agree, haven't had flooding IMBY like this in a few years. Quote Share this post Link to post Share on other sites

C.A.P.E. Posted July 22, 2018 Just a parade of vorticity impulses moving through over the next 48 hours on the NAM. Looks like as the closed low sinks a bit south and east, the track of the vort maxes/associated enhanced lift, and thus the threat for heavy rain, will shift/expand a bit further east tomorrow. Round 4 today just missed here again. Pretty amazing looking at the storm totals per radar for today. A north-south axis of 2-4 inches through Talbot and Queen Annes counties a few miles to my west, and nothing here. Quote Share this post Link to post Share on other sites
mattie g Posted July 22, 2018 Glad we got basically shut out in Burke today. Aside from about 20 minutes of moderate rain around lunchtime, we’ve only had spotty drizzle a couple times. Quote Share this post Link to post Share on other sites
JWilliam9830 Posted July 22, 2018 Picked up 0.09 inches of rain so far today, 0.04'' in the small cell that just passed over me. 79/79, RH 99%. Downright muggy Sunset 10 minutes earlier than a month ago. One small step closer to winter, hope we get buried. Quote Share this post Link to post Share on other sites
09-10 analogy Posted July 22, 2018 Streets around here were raging brooks last night, I think the city needs to clear some gutter infrastructure, it was vaguely reminiscent of June 2006. I know yesterday was a historic event, not downplaying it all, but there weren't any periods what I would call torrential rain (but I may have missed them, wasn't monitoring all day), just long extended periods of heavy rain. ( Then again, "torrential" is one of those notoriously subjective words used to describe weather that helps to make boards like this rock with such vigorous disagreement. With me, it's a bias, I suppose: unless there's t&l (or tropical) involved, I tend to not categorize rainfall as torrential. Again, totally subjective.. Certainly the statistics and reported rainfall verify that Saturday was indeed an area-wide heavy rain event of significance. Along with the windstorm in March, probably the two most noteworthy weather events of the year so far, off the top of my head. Well, that and the extended cold that kicked off January. With the breezy winds and the relatively cool temps, yesterday had the feel of a fall nor'easter (I'm sure someone's noted that before, haven't read through the thread.) Interesting to read about t/l, especially to the east, did not notice any of that, yesterday or today. Today has featured some picturesque cloud contrasts; no towering c-nimbus or low rolling shelfs, of course, but just recently the southern horizon was dark and ominous and the northern was much brighter with some grey scud moving across. This has been, IMO, an eminently tolerable summer so far; except for a few days earlier in the month and maybe last week, it hasn't been very oppressive at all. I think DCA has topped out at 97 so far? That's not bad at all. Quote Share this post Link to post Share on other sites

Looks like either side of the bay got hit hard today. Multiple rounds of storms over the same areas. Makes sense given the location of the vort max moving through just to the west over central VA/MD as advertised by the meso models early this morning. Probably some bay breeze contribution at the lower levels as well. Quote Share this post Link to post Share on other sites

I just got a pix sent to me from some family outside San Antonio. They got into their dark, parked car, and the temp read 140 degrees! To keep this on topic, I got .40" rain around 2pm today. DCA got .86 around the same time. It's been dark since, but further rain seems to have missed us. 1 Quote Share this post Link to post Share on other sites

Could be a weak impulse, but a more impressive one looks to swing through tomorrow. There is also a stationary boundary lying SW to NE from southern MD to SE PA associated with the action today, so that may continue to serve as a focus for any convection that occurs overnight, although it will probably be weaker due to loss of insolation. 1 Quote Share this post Link to post Share on other sites
C.A.P.E.

CONCERNING...HEAVY RAINFALL...FLASH FLOODING LIKELY VALID 222158Z - 230145Z SUMMARY...A COUPLE OF COMPLEXES FED BY SWLY ONSHORE FLOW FOCUSED BY RIVERS POSE LIKELY FLASH FLOODING ACROSS SE PA TO CENTRAL MD OVER THE NEXT FEW HOURS. DISCUSSION...MCV LIFTING INTO CENTRAL PA CONTINUES TO HAVE AN ACTIVE CONVECTIVE COMPLEX ALONG THE EASTERN PERIPHERY OF ITS INFLUENCE IN SE PA/EXT NE MD AND N DE ATTM. STRONG SFC FLOW UP THE DELAWARE RIVER AND SLIGHT TURNING AT THE APEX OF THE CHESAPEAKE BAY LEADING TO VERY STRONG MST CONVERGENCE AND BACKBUILDING GIVEN STRONGER INFLOW AT THE EDGE OF THE MID-LEVEL TROF/CONFLUENCE BAND. THIS ALSO INTERSECTS GENERALLY WITH THE WARM FRONT THAT CONTINUES HANG THROUGH SE PA INTO ANNE ARUNDEL COUNTY MD INTO THE PIEDMONT REGION OF VA. STRONG MST CONVERGENCE ALONG THE WARM FRONT IS SUPPORTING CONVECTIVE DEVELOPMENT ALONG ITS LENGTH INTO VA BUT GIVEN THE STUBBORN NATURE OF THE RIDGING OVER WEST CENTRAL MD INTO NW VA...THERE CONTINUES TO BE SLOW NNW MOVEMENT OF THE FRONT ALLOWING FOR BACKBUILDING ALONG THE UPSTREAM EDGE AND COMPOUNDING RAINFALL TOTALS DOWNSTREAM. THE BEST TRAINING REMAINS WHERE THE FRONT IS MORE PARALLEL TO THE MEAN FLOW ACROSS SOUTHERN MD TOWARD BALTIMORE CITY. IN ADDITION ANOTHER SUBTLE S/W WILL HAS INCREASED WAA ACROSS THE NORTHERN NECK OF VA LIFTING NORTH SUPPORTING A BAND OF CONVECTION THAT WILL LIKELY BE ENHANCED BY THIS PARALLEL NATURE TO THE FRONT AND THE INCREASED LOW LEVEL FLUX/CONVERGENCE CONTINUING THE FLASH FLOOD THREAT FOR THE NEXT FEW HOURS ALONG THE LENGTH OF THE CHESAPEAKE BAY. 1 Quote Share this post Link to post Share on other sites
Stormpc Posted July 23, 2018 .60 at my house just since sunrise. .52 from that shower earlier this evening. .08 from a lunchtime shower. Radar is popping discrete cells to the south that may train right up 95 toward PW and Fairfax. We will see. Big 2 day event. No doubt. Quote Share this post Link to post Share on other sites

ThePhotoGuy Posted July 23, 2018 Really heavy rain this afternoon/evening. Another 2.50 inches for a total of 7.50 for the past two days. I was coming home, local roads were covered over and flooded in spots that never flood. I noticed in my neighborhood a couple yards that had at least 4-5 inches in it flowing to the house. My neighborhood never floods during rainstorms and only floods in some spots during storm surge from tropical storms. It was impressive to see it today. 1 Quote Share this post Link to post Share on other sites
