CAPE Posted July 22, 2018 Share Posted July 22, 2018 46 minutes ago, dailylurker said: Almost 4" today. 2" fell in about 45 minutes. I've got flooding like I've never seen in my life. It's dumping rain as I type. 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. Link to comment Share on other sites More sharing options...

Tell me about it. 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.

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.

CAPE Posted July 23, 2018 Share Posted July 23, 2018 Wow what a great technical discussion from WPC- MESOSCALE PRECIPITATION DISCUSSION 0515...CORRECTED NWS WEATHER PREDICTION CENTER COLLEGE PARK MD 612 PM EDT SUN JUL 22 2018 CORRECTED FOR FLASH FLOODING LIKELY IN CONCERNING LINE AREAS AFFECTED...SOUTHEAST PA...CENTRAL MD...EXT NORTHERN VA...EXT NORTHERN DE... 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.

Stormpc Posted July 23, 2018 Share 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. Link to comment Share on other sites More sharing options...

ThePhotoGuy Posted July 23, 2018 Share 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.
