yoda Posted May 27, 2022 Share Posted May 27, 2022 Updated morning AFD from LWX (as of 1025am) says that the afternoon/evening threat for severe is "still in play" .NEAR TERM /THROUGH TONIGHT/... Initial line associated with low level jet continues to slowly move eastward across the area. Tornado Watch remains in place through 2 PM. Some stabilization has been occurring with northward extent as storms interact with weaker instability and more CIN across our forecast area. Appears an effective warm front is lurking between DC and Fredericksburg, and theta-e advection along with some diurnal heating will result in higher instability spreading northward ahead of the line as it reaches the I-95 corridor during the midday hours. Therefore damaging winds and a brief tornado remain threats as low level shear values remain high. While the overall line will progress to the east, there is potential for brief training and we have seen rain amounts of 1-2 inches in an hour where this occurs. The second round late this afternoon and into this evening is still somewhat uncertain, but additional severe storms and localized flooding issues are still within play. 1 Link to comment Share on other sites More sharing options...

Eskimo Joe Posted May 27, 2022 Share Posted May 27, 2022 Latest HRRR has a decent 2nd line coming through during prime heating. Currently visible satellite shows outright clearing behind this first batch so it's certainly possible. 2 Link to comment Share on other sites More sharing options...

Currently visible satellite shows outright clearing behind this first batch so it's certainly possible. Will be interesting to see trends with further HRRR runs as this line gets out of the way and the airmass behind it is ingested into the model. 1 Link to comment Share on other sites More sharing options...

biodhokie Posted May 27, 2022 Share Posted May 27, 2022 Parents told me the SVR verified in Spotsy County. They looked to be a few miles NW of the circulation track as it crossed 208 by the courthouse so they couldn't tell me any verify for the TOR.
