midatlanticweather Posted August 28, 2021 Share Posted August 28, 2021 Mesoscale Discussion 1628 NWS Storm Prediction Center Norman OK 1205 PM CDT Sat Aug 28 2021 Areas affected...South-Central Pennsylvania...Western Maryland...Eastern West Virginia...and Northern Virginia Concerning...Severe potential...Watch unlikely Valid 281705Z - 281900Z Probability of Watch Issuance...5 percent SUMMARY...Isolated damaging wind gusts possible with the strongest storms this afternoon. DISCUSSION...Visible satellite shows strong insolation this morning has given way to scattered convective development over the northern part of region. Surface temperatures have warmed into the mid 80s F amid rich low-level moisture (dew point temperatures in the upper 60s and low 70s F). This is yielding around 1000 J/kg of MLCAPE. With weak convective inhibition and continued heating/destabilization, additional pulse-like storms are expected to develop throughout the afternoon and gradually move southeastward with time. Weak flow throughout the atmosphere will limit storm organization, however, a few isolated damaging wind gusts will be possible with the strongest storms given at least marginal low-level lapse rates near 8 C/km that should develop, particularly over parts of northern Virginia and vicinity later this afternoon. Given the expectation for an isolated damaging wind threat, watch issuance is not expected. ..Karstens/Grams.. 08/28/2021 1 Link to comment Share on other sites More sharing options...

yoda Posted August 29, 2021 Share Posted August 29, 2021 00z NAM hitting on Tuesday afternoon for some good severe 1 Link to comment Share on other sites More sharing options...
CAPE Posted August 29, 2021 Share Posted August 29, 2021 With a more NW track, looks like there may be a decent risk of severe for I-95 and points east. Mount Holly mentioning the possibility in their AM AFD. Models are converging on the eventual track of the remnant low, with the 00z CMC making a noticeable shift northward, much more in line with the ECMWF/GFS. The consensus track would lead to the heaviest rainfall axis generally in the northern half of the CWA, with alarming QPF of 2-5+ inches in a broad region along and north of the track of the low. Meanwhile, the warm sector may sneak into the southern CWA, where a threat of strong to severe storms would exist (given sufficient instability and strong vertical shear). In short, the latest models suggest a multi-faceted and rather impactful event for the region. Continue to monitor the latest forecasts, as we continue to fine-tune the forecast axis of heaviest rainfall and the areas with the highest risk of severe weather. 3 1 Link to comment Share on other sites More sharing options...
