MD 2021 CONCERNING SEVERE THUNDERSTORM WATCH 659... FOR PORTIONS OF FAR NORTHERN OHIO INTO EXTREME NORTHWESTERN PENNSYLVANIA AND EXTREME SOUTHWESTERN NEW YORK
Mesoscale Discussion 2021 NWS Storm Prediction Center Norman OK 0739 PM CDT Tue Aug 27 2024 Areas affected...portions of far northern Ohio into extreme northwestern Pennsylvania and extreme southwestern New York Concerning...Severe Thunderstorm Watch 659... Valid 280039Z - 280215Z The severe weather threat for Severe Thunderstorm Watch 659 continues. SUMMARY...Some severe threat will persist for a few more hours in and immediately surrounding Severe Thunderstorm Watch 659. Damaging gusts remain the primary concern. DISCUSSION...A pronounced cold pool, originating from a mature persistent elongated convective system, has surged southeastward across Lake Erie over the past couple of hours. At least a few severe gusts have been observed, and some convective rejuvenation has occurred along the cold pool leading edge. Buoyancy decreases/MLCINH increases with eastward and southward extent ahead of the ongoing storms/cold pool. However, the fast pace of the cold pool suggests that continued cellular regeneration and accompanying damaging wind gust potential will continue for at least a couple more hours. ..Squitieri.. 08/28/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 2020 CONCERNING SEVERE THUNDERSTORM WATCH 658... FOR NORTHEAST IL INTO EXTREME NORTHWEST IN/SOUTHWEST MI
Mesoscale Discussion 2020 NWS Storm Prediction Center Norman OK 0624 PM CDT Tue Aug 27 2024 Areas affected...Northeast IL into extreme northwest IN/southwest MI Concerning...Severe Thunderstorm Watch 658... Valid 272324Z - 280100Z The severe weather threat for Severe Thunderstorm Watch 658 continues. SUMMARY...The severe threat will spread southeastward through early evening. DISCUSSION...A supercell has developed across far northeast IL, with reports of severe wind gusts and hail up to golf ball size thus far. Large to extreme instability will continue to support vigorous updrafts early this evening. Deep-layer shear becomes increasingly modest with southward extent, but will remain locally enhanced near a lake-enhanced surface boundary draped northwest to southeast across the Chicagoland vicinity. The ongoing supercell may propagate southeastward near this boundary, with a continued threat of large hail and severe/damaging gusts. There is some potential for additional development near the trailing outflow, with increasing cumulus noted in Kane County. Depending on the number and proximity of storms that develop early this evening, some upscale growth into a southeastward-moving cluster will be possible with time. Downstream watch issuance is possible if a severe threat begins to approach northwest IN/southwest MI. ..Dean/Gleason.. 08/27/2024 ...Please see www.spc.noaa.gov for graphic product...

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0745 PM CDT Tue Aug 27 2024 Valid 280100Z - 281200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE SOUTHERN GREAT LAKES AND PORTIONS OF THE MIDWEST... ...SUMMARY... Severe thunderstorms capable of damaging thunderstorm winds and isolated large hail remain possible across the southern Great Lakes region and portions of the Midwest tonight. ...01z Update... Upper ridge is flattening across the Great Lakes this evening in response to a progressive short-wave trough advancing east across the upper MS Valley. This feature will deamplify as it shifts into the central Great Lakes by 28/12z. Westerly flow is gradually deepening across this region and low-level convergence is not particularly focused, though a synoptic front does currently extend from northern Lower MI/south-central WI arcing into southern NE. Multiple thunderstorm complexes have spread across WI/MI with the leading edge of one MCS now advancing southeast of Lake Erie. This activity should struggle as it propagates into eastern OH/western PA as buoyancy is not particularly strong across this portion of the OH Valley. Upstream along the trailing synoptic front, a reservoir of extreme instability has yet to be overturned from northern IL into northern MO. Robust convection is tracking southeast along a lake breeze near the Chicago metro. These storms will propagate into northern IN over the next several hours with an attendant risk for hail/wind. Farther southwest, weaker steering currents are contributing to slow-moving clusters along the front across northern MO into northeast KS. This activity will be more deviant in storm motion due to weak flow, driven largely by convective outflow and the presence of extreme instability. Hail/wind remain possible with these storms. ..Darrow.. 08/28/2024 Read more

WW 659 SEVERE TSTM OH PA LE 272235Z - 280400Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 659 NWS Storm Prediction Center Norman OK 635 PM EDT Tue Aug 27 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Northern Ohio Far Northwest Pennsylvania Lake Erie * Effective this Tuesday night from 635 PM until Midnight EDT. * Primary threats include... Scattered damaging wind gusts to 70 mph possible Isolated large hail events to 1 inch in diameter possible SUMMARY...A line of thunderstorms should continue to pose some threat for severe/damaging winds up to 60-70 mph as it moves east-southeastward this evening across parts of northern Ohio and eventually far northwest Pennsylvania. The severe thunderstorm watch area is approximately along and 25 statute miles north and south of a line from 15 miles south of Toledo OH to 20 miles east southeast of Erie PA. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU9). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes. && OTHER WATCH INFORMATION...CONTINUE...WW 656...WW 657...WW 658... AVIATION...A few severe thunderstorms with hail surface and aloft to 1 inch. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500.
