Severe Storm Risk
-There is a Slight Severe Storm Risk for your location. Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS OVER CENTRAL AND EASTERN OKLAHOMA THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM SOUTHERN NEW ENGLAND INTO THE DELMARVA...OVER THE CENTRAL HIGH PLAINS...AND FROM THE OZARK PLATEAU INTO SOUTHERN HIGH PLAINS SUMMARY Severe storms capable of severe winds with gusts in excess of 75 mph and isolated occurrences of large hail remain possible across Oklahoma, with more sporadic occurrences of large hail and damaging winds from the Ozark Plateau into southern High Plains. Damaging winds and some hail threat will continue from southern New England into the Delmarva this evening. Isolated occurrences of large hail and damaging winds remain possible over the central High Plains. Southern Plains into the Ozark Plateau Recent radar data indicate the evolution of a well-defined bow echo over northeast OK with the crest of that feature moving toward Tulsa at around 45 mph. Additional intense storms exhibiting some supercell characteristics are being observed on the western flank of the bow echo over north-central OK, with more widely scattered strong to severe storm development from northwest OK into east-central NM. The 00z OUN sounding is likely a good representation of the inflow air mass to the ongoing storms, featuring modestly steep lapse rates and with MLCAPE of around 2500 J/kg. The current KICT and KVNX VWPs are sampling stronger winds above 5-6 km AGL than those observed by the 00Z OUN sounding, suggesting that deep-layer shear is likely closer to 40-45 kt in the vicinity of the ongoing storms. Latest WoFS and HRRR data suggest the potential for a swath of intense straight-line winds with gusts in excess of 75 mph over the next 2-3 hours generally east of I-35 in OK in association with the bow echo. More sporadic occurrences of large hail and damaging winds will remain possible from western OK into eastern NM. For additional near-term information, see MCD 1507. Southern New England to the Delmarva Multiple clusters of strong to severe thunderstorms are ongoing as of 00Z with several reports of wind damage and a 58 mph wind gust at BWI Marshall Airport. The inflow air mass remains hot and moist this evening with MLCAPE of 1500-2500 J/kg, per latest mesoanalysis. Regional VWPs and the 00Z OKX sounding indicate the strongest mid-level flow and resultant vertical shear across the middle and lower Hudson Valley into southern New England, which will support embedded bowing and supercell structures capable of damaging winds and large hail. Weaker vertical shear with southward extent into the Delmarva is being offset by comparatively stronger instability, which should allow for a continued damaging wind threat with storms moving toward the coast. For additional near-term details, see MCD 1505. Eastern Colorado into Central Nebraska Clusters of strong to severe thunderstorms are ongoing this evening from the vicinity of Broken Bow, NE into northeast CO amidst a steep lapse rate and moderately unstable air mass, per 00Z LBF sounding. In the absence of appreciable forcing for ascent, storms should tend to weaken over the next couple of hours. In the near time, hail up to 1.5" and locally severe wind gusts will remain possible. For additional near-term details, see MCD 1506.
