PUBLIC SEVERE WEATHER OUTLOOK NWS STORM PREDICTION CENTER NORMAN OK 0840 PM CDT MON MAY 19 2025 ...Severe thunderstorms expected over parts of the southern Plains into the Ozarks and mid Mississippi Valley this evening and overnight... * LOCATIONS... Western and Northern Arkansas Missouri Far Eastern Oklahoma North-Central and Northeast Texas Southern Illinois * HAZARDS... Widespread damaging winds, some hurricane force Several tornadoes, a few intense Scattered large hail, some baseball size * SUMMARY... A significant severe weather episode should continue tonight across parts of the South-Central States. Strong tornadoes, scattered to widespread damaging wind swaths, and very large hail remain possible. Preparedness actions... Tornadoes at night can be particularly dangerous because they are usually fast-moving and difficult to see. Stay tuned to NOAA Weather Radio, weather.gov, or other media for watches and warnings. A tornado watch means that conditions are favorable for tornadoes to form during the next several hours. If a tornado warning is issued for your area, move to a place of safety, ideally in a basement or interior room on the lowest floor of a sturdy building. Read more

Mesoscale Discussion 0890 NWS Storm Prediction Center Norman OK 0702 PM CDT Mon May 19 2025 Areas affected...Parts of the Tennessee Valley Concerning...Severe potential...Watch unlikely Valid 200002Z - 200130Z Probability of Watch Issuance...20 percent SUMMARY...Isolated risk of marginally severe hail and locally damaging wind gusts will persist for a couple hours. A watch is not expected. DISCUSSION...Isolated cellular convection is evolving in the vicinity of a warm front draped across the TN Valley, where earlier heating of a moist boundary layer (upper 60s/lower 70s dewpoints) contributed to moderate surface-based instability. An elongated/straight hodograph (around 30-40 kt of 0-6 km shear) sampled by regional VWP may support marginal/brief splitting supercell structures -- capable of producing marginally severe hail and locally damaging wind gusts. However, with shortwave ridging across the area and loss of daytime heating, the overall severe risk should remain too isolated/limited for a watch. ..Weinman/Gleason.. 05/20/2025 ...Please see www.spc.noaa.gov for graphic product...

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0759 PM CDT Mon May 19 2025 Valid 200100Z - 201200Z ...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS IN NORTHWEST ARKANSAS...SOUTHWEST MISSOURI...AND FAR EASTERN OKLAHOMA... ...SUMMARY... A significant severe weather episode should continue tonight across parts of the South-Central States. Strong tornadoes, scattered to widespread damaging wind swaths, and very large hail remain possible. ...TX/OK to the Mid-MS/Lower OH Valley... While extensive overturning has already occurred, there are several primary areas of concern for severe storms tonight. In the near-term, the greatest tornado/wind potential should exist with a pair of supercells embedded within a broad southwest/northeast-oriented QLCS from the Ozark Plateau to the Red River. With the most pronounced low-level shear ahead of this portion of the QLCS, strong tornado and significant severe wind potential should persist into late evening. Despite stronger large-scale ascent focused west, the organized nature of the QLCS suggests that embedded wind gusts of 60-75 mph could produce a potentially widespread damaging wind swath that may persist east-northeast overnight. Have expanded outlook categories farther east across the Mid-MS/Lower OH Valley. The trailing portion of the QLCS has been stubborn to accelerate east, but should begin to do so in the next couple hours. Short-term guidance has been insistent on additional convection developing back west with strengthening ascent ahead of the primary shortwave trough from central to eastern OK tonight. This could pose another round of severe hail/wind threat persisting into the early morning. ...KS and the Lower/Mid-MO Valley... Scattered severe storms should generally wane during the late evening. But similar to the OK redevelopment, post-dryline/frontal high-based convection should expand east-northeast and likely impinge on lingering strong to severe storms across eastern KS. This could maintain at least isolated severe storms lingering overnight. ..Grams.. 05/20/2025 Read more
