09-10 analogy Posted August 6, 2023 Share Posted August 6, 2023 If I'm reading Sterling's discussion correctly, if the storms hold off until later Monday afternoon/evening, the LLJ would give a boost to mesocyclone development. Is this akin to what I often read in discussions of Dixie tornado threats, which often mention a nighttime tornado threat being heightened by a nocturnal LLJ? And, no, I'm not comparing tomorrow to Dixie outbreaks. There is, however, this August event: https://michigan-weather-center.org/the-tornado-and-the-burning-of-washington-august-25-1814#:~:text=The tornado tore through the,of homes and scattered about. 3 Link to comment Share on other sites More sharing options...

AmericanWxFreak Posted August 6, 2023 Share Posted August 6, 2023 Here’s the 3k for this evening/tonight and tomorrow. Brings a pretty healthy looking line towards us this evening but it goes poof right before reaching our area. 4-5 hours later it brings some cells up from the south for some of us tonight. Pretty active radar simulation for tomorrow but there’s definitely a focus on south of 70 again - just cherry picked one image which doesn’t tell the whole story.

Seems like some agreement among models for the first round to dry up but for there to be a cluster of storms moving along 95 around 10pm-1am tonight. 2 Link to comment Share on other sites More sharing options...
87storms Posted August 6, 2023 Share Posted August 6, 2023 I would get 0 rain from the NAM. Not expecting much anyways considering I’m in the MRGL.I just go by feel at this point. It’s humid (check)…and there’s sun (check). Rest is tbd like almost every other event here lol. What I do know is this is absolutely my kind of weather aka sunshine/humidity and a chance of storms later. I have no interest in cool/dry/cloudy/windy in the summer (we get enough of that from November to April). 1 Link to comment Share on other sites More sharing options...

George BM Posted August 6, 2023 Share Posted August 6, 2023 ...OH Valley to Mid-Atlantic to the southern Appalachians and Carolinas... Scattered showers and isolated storms are forecast to be ongoing over the OH Valley Monday morning with more widely spaced convection trailing west-southwest into the Mid South/Ozarks. Considerable cloud cover with northward extent over a large moist/warm sector will limit destabilization into portions of PA and north. Farther south, heating of a very moist boundary layer will yield a moderate to very unstable airmass (1500 to 3000+ J/kg MLCAPE) from PA southward into the southern Appalachians. Multiple bands and clusters will likely begin to develop towards midday over the upper OH Valley and central Appalachians. Less certain is convective timing over the TN Valley where a large spread of model solutions is currently depicted. Nonetheless, scattered thunderstorms will likely develop by early to mid afternoon and become quite extensive from northern AL/GA into PA/VA/WV/MD. A mix of semi-discrete cells and clusters are possible initially and a risk for all severe hazards is expected given favorable shear profiles for storm organization/low-level rotation. Upscale growth is expected as storms move into the northern VA/MD and Chesapeake Bay vicinity during the late afternoon/early evening where the wind risk will seemingly be maximized. Much of the activity will eventually move east of the Mid-Atlantic coast during the evening and areas farther south through the Carolina Piedmont and into the coastal plain. Fun sounding disco for this region. Link to comment Share on other sites More sharing options...

Amped Posted August 6, 2023 Share Posted August 6, 2023 Best chance for discrete cells will be in northwestern areas when the storms first develop. It will probably merge into some sort of an MCS by the time it gets to I95 leading to more of a widespread wind threat. 1 Link to comment Share on other sites More sharing options...

I think some of it will depend on how much sun we get tomorrow morning with regards to cloud debris, as you and others have mentioned. If we can get sun going by like 10am... we might be off to the races. I expect some decent tornado potential tomorrow with the curved hodo's and low LCLs as well. 1 Link to comment Share on other sites More sharing options...

yoda Posted August 6, 2023 Share Posted August 6, 2023 Afternoon AFD from LWX about tomorrow .SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY NIGHT/... Given the persistent low-level warm advection overnight, low clouds and patchy fog will likely blanket portions of the area. How quickly the mid-summer solar angle can erode these stratus clouds will dictate the timing and intensity of Monday`s convective weather event. All severe parameters are coming into alignment, accompanied by rather extreme shear profiles for early August. A robust shortwave tracking from the Upper Great Lakes will arrive during the peak in the diurnal heating cycle. Further, between 18Z Monday and 06Z Tuesday, 12-hour height falls are likely to run between 5-7 dm which is impressive for the time of year. The Storm Prediction Center has highlighted the entire area in an Enhanced Risk for severe thunderstorms. While the main threat is damaging to locally destructive winds, a few tornadoes and large hail reports are also possible. If convection is able to thrive into the mid/late evening, an increasing low-level jet will lead to enlarged 0-1 km hodographs. This would support some degree of tornado risk if the event persists. An additional issue will be the risk for flash flooding given the threat for 1-2 inches of rainfall, locally up to 3-5 inches. The HREF signal really jumps off the charts with some of the Day 2 totals noted in a few of its ensemble members. Depending on how this evening`s convection pans out, this will dictate areas which would be vulnerable to additional heavy rainfall. 2 Link to comment Share on other sites More sharing options...
