WW 658 SEVERE TSTM IL IN WI LM 272210Z - 280400Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 658 NWS Storm Prediction Center Norman OK 510 PM CDT Tue Aug 27 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Northern Illinois Northwest Indiana Far Southeast Wisconsin Lake Michigan * Effective this Tuesday afternoon and evening from 510 PM until 1100 PM CDT. * Primary threats include... Scattered damaging winds and isolated significant gusts to 75 mph possible Scattered large hail and isolated very large hail events to 2 inches in diameter possible SUMMARY...Thunderstorms should continue to grow in coverage and intensity this afternoon and evening as they move east-southeastward. Large hail around 1-2 inches in diameter will be a threat with any supercells, but severe/damaging winds generally around 60-70 mph may also occur if thunderstorms can grow into a small cluster. The severe thunderstorm watch area is approximately along and 45 statute miles east and west of a line from 15 miles west of Racine WI to 55 miles southeast of Marseilles IL. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU8). 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... AVIATION...A few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 65 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 30025. ...Gleason Read more

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...

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0447 PM CDT Tue Aug 27 2024 Valid 291200Z - 041200Z In the wake of a midlevel low advancing eastward across the northern Plains, an expansive mid/upper-level ridge will temporarily build over the West through around Day 5/Saturday. While weak surface winds should generally mitigate fire-weather concerns during that time, boundary-layer warming and some drying of fuels is expected, most notably across the Northwest. Thereafter, a midlevel trough/low will approach the Pacific Northwest, with weak midlevel height falls beginning to impinge on coastal OR/WA as early as Day 5/Saturday. Forcing for ascent will not be particularly strong at that time, though gradually increasing midlevel moisture/instability may support an isolated thunderstorm risk along/west of the Cascades (though confidence in this scenario is low). On Days 6-7/Sunday-Monday, the midlevel trough/low will continue east-northeastward across the Northwest, with more substantial midlevel height falls overspreading the region. Increasing midlevel moisture atop a relatively warm/dry boundary layer will support mixed wet/dry thunderstorms, given the ample large-scale ascent. Confidence in thunderstorm development is currently highest across portions of OR on Day 7/Monday -- when the strongest ascent should phase with favorable PW/instability. Dry Thunderstorm probabilities have been withheld owing to uncertainties regarding fuel receptiveness and overall timing of thunderstorm development, though probabilities may eventually be needed as those details become more clear. ..Weinman.. 08/27/2024 ...Please see www.spc.noaa.gov/fire for graphic product...
