Scattered large hail and isolated very large hail events to 2 inches in diameter possible Isolated damaging wind gusts to 70 mph possible SUMMARY...Widely scattered thunderstorms will intensify early this evening across central Oklahoma and drift eastward across the watch area. Initial storms will pose a risk of large hail, with an increasing threat of gusty/damaging winds later this evening. The severe thunderstorm watch area is approximately along and 50 statute miles north and south of a line from 35 miles northwest of Chickasha OK to 15 miles east northeast of Mcalester OK. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU2). 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 681... AVIATION...A few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 28030. ...Hart Read more

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0443 PM CDT Tue Sep 24 2024 Valid 261200Z - 021200Z A closed upper-low will develop and become cut-off and remain across portions of the Mississippi Valley through much of the extended period. During this period, Hurricane Helene will also be absorbed into the broader upper flow and bring an anomalously moist airmass into the region. The combination of cool and moist conditions associated with this upper pattern will alleviate most fire weather concerns across the eastern CONUS through the extended period. Ridging will result in warm and dry conditions across much of the western CONUS during the period. While critically dry fuels are mostly sparse across the western CONUS presently, this extended warm/dry period may result in larger regions of critically dry fuels (particularly fine fuels) by the end of the weekend when the next trough crosses the western CONUS. At this time the forecast winds/relative humidity are not strong/dry enough to warrant any Critical probabilities, especially given the questionable/sparse dry fuels presently. ..Bentley.. 09/24/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

Valid 242001Z - 242200Z The severe weather threat for Severe Thunderstorm Watch 681 continues. SUMMARY...Isolated risk for strong/damaging gusts and marginal hail continues in/near WW 681. DISCUSSION...Latest radar loop shows scattered thunderstorms ongoing near and ahead of a slowly advancing surface cold front that stretches from Indiana to the Tennessee Valley. Isolated stronger/occasionally severe storms continue across this area, where a favorable combination of moderate instability and moderate speed shear exists. Risk should continue in a relatively steady-state manner over the next few hours, shifting gradually eastward with time. ..Goss.. 09/24/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 2102 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR SOUTHERN LOWER MICHIGAN INTO INDIANA AND NORTHWESTERN OHIO
Mesoscale Discussion 2102 NWS Storm Prediction Center Norman OK 0110 PM CDT Tue Sep 24 2024 Areas affected...southern Lower Michigan into Indiana and northwestern Ohio Concerning...Severe potential...Watch unlikely Valid 241810Z - 242015Z Probability of Watch Issuance...20 percent SUMMARY...Local risk for a couple of strong gusts and marginal hail, and possibly a brief tornado or two, is expected to evolve across the southern Lower Michigan/Indiana/northwestern Ohio vicinity this afternoon. Isolated/marginal nature of risk may preclude the need for WW issuance, but we will continue to monitor evolution. DISCUSSION...Latest visible satellite imagery shows cloud cover decreasing slightly ahead of a mid-level cyclonic circulation moving northeastward across the area. This, combined with associated/cool temperatures aloft and modest afternoon heating has resulted in development of 500 to 1000 J/kg mixed-layer CAPE. Within the zone of broad/background ascent, some convective increase is noted over the past hour, with an associated uptick in lightning. This trend should continue over the next couple of hours -- likely resulting in a few relatively vigorous/low-topped storms which may prove capable of producing marginal hail and a strong gust or two. A brief tornado or two will also be possible, particularly across southern Lower Michigan and northern Indiana where low-level flow is backed/east-southeasterly near and north of a weak warm front. At this time, overall risk is expected to remain localized -- too isolated for serious WW consideration. However, we will continue to monitor short-term trends across this area that could warrant reconsideration of the need for a watch. ..Goss/Guyer.. 09/24/2024 ...Please see www.spc.noaa.gov for graphic product...

See previous discussion below. ..Bentley.. 09/24/2024 .PREV DISCUSSION... /ISSUED 0155 AM CDT Tue Sep 24 2024/ ...Synopsis... A trough will transverse eastward across the northern portion of a western US ridge on Wednesday, bringing enhanced mid-level flow over the Cascades into western Washington and Oregon. Across southwestern Oregon, sustained winds around 15-20 mph will overlap relative humidity reductions to around 20-25 percent. Elevated fire weather conditions will be possible. Receptive fuels in this region are spotty, which leads to low confidence in including an area at this time. ...Please see www.spc.noaa.gov/fire for graphic product... Read more
