105 ACUS11 KWNS 092306 SWOMCD SPC MCD 092306 NJZ000-MDZ000-DEZ000-VAZ000-100030- Mesoscale Discussion 1563 NWS Storm Prediction Center Norman OK 0606 PM CDT Thu Jul 09 2026 Areas affected...Portions of the Mid-Atlantic Coastal States Concerning...Severe Thunderstorm Watch 474... Valid 092306Z - 100030Z The severe weather threat for Severe Thunderstorm Watch 474 continues. SUMMARY...The threat for damaging winds continues across WW 474 as a line of strong to severe thunderstorms moves eastward, and eventually, offshore. Thunderstorm wind gusts of 55-70 MPH remain possible. DISCUSSION...Linear convection within WW 474 continues to move east-southeast across the Mid-Atlantic coastal states and will continue to pose a hazard for damaging straight-line wind gusts. Sufficient buoyancy and deep-layer shear will continue to support linear bowing segments before ultimately moving offshore into the Atlantic. The best short-term corridor for damaging wind gusts appears to be across portions of Virginia and Maryland, where the combination of MLCAPE and deep-layer shear is best maximized and current radar trends suggest the strongest updrafts have developed. ..Halbert.. 07/09/2026 ...Please see www.spc.noaa.gov for graphic product...

Valid 092350Z - 100115Z The severe weather threat for Severe Thunderstorm Watch 475 continues. SUMMARY...The severe-wind threat may increase into this evening, in addition to a continued isolated hail threat. DISCUSSION...Convection across eastern CO has gradually evolved into more of a linear mode as of 2345 UTC. Steep low-level lapse rates, favorable low-level easterly flow, and increasing moisture/buoyancy downstream of this convection may result in an increasing severe-wind threat into the evening. MLCAPE of near/above 1500 J/kg and moderate deep-layer shear will remain supportive of organized convection, and a swath of 60-80 mph gusts will be possible if a more organized cold pool can evolve with time. The strongest embedded updrafts and cells ahead of or along the periphery of the developing line will also continue to pose a threat of isolated large hail into early evening. ..Dean.. 07/09/2026 ...Please see www.spc.noaa.gov for graphic product...
