Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0349 AM CDT Sun May 26 2024 Valid 291200Z - 031200Z ...DISCUSSION... In general, medium-range models indicate that larger-scale mid/upper troughing will slowly progress eastward across and offshore of the Atlantic Seaboard through the middle to latter portion of the coming work week. As this occurs, flow across the northern mid-latitudes of the Pacific into North America may trend less amplified, while flow across the southern mid- and subtropical latitudes trends a bit more amplified. It appears that this may include modest mid-level troughing approaching the California and Baja coast next weekend, upstream of building large-scale ridging across the southern Rockies through the middle and lower Mississippi Valley. Shorter wavelength developments are substantially more unclear throughout the period due to sizable model spread. Beneath this regime, moderate to strong potential instability, associated with seasonably moist boundary-layer air beneath steep lower/mid-tropospheric lapse rates, may mostly remain confined to the higher plains to the lee of the Front Range southward into the Pecos Valley. As mid-level heights fall to the south of the initially prominent trough slowly progressing to the east of the northern Rockies late this week, it is possible that storms developing in the late afternoons off the higher terrain could evolve into clusters posing at least some severe weather threat across the adjacent plains. However, due to generally low predictability, severe weather probabilities are being maintained at less than 15 percent. Read more

WW 311 TORNADO AR KS MO OK 260200Z - 261000Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 311 NWS Storm Prediction Center Norman OK 900 PM CDT Sat May 25 2024 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Northwest Arkansas Eastern Kansas Western Missouri Northeast Oklahoma * Effective this Saturday night and Sunday morning from 900 PM until 500 AM CDT. * Primary threats include... A few tornadoes likely with a couple intense tornadoes possible Widespread damaging winds and isolated significant gusts to 80 mph likely Scattered large hail and isolated very large hail events to 2 inches in diameter likely SUMMARY...Scattered clusters of severe thunderstorms, including supercells and linear bands, are forecast to move east into the Watch area this evening and persist into the overnight. The stronger supercells will potentially be capable of a tornado risk, in addition to a threat for large hail and severe gusts. Eventual upscale growth into one or more severe linear bands of storms is expected and the threat will primarily transition to a risk for damaging gusts and perhaps a couple of tornadoes. The tornado watch area is approximately along and 75 statute miles east and west of a line from 20 miles east northeast of Leavenworth KS to 35 miles west southwest of Fayetteville AR. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU1). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Tornado Watch means conditions are favorable for tornadoes and 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. && OTHER WATCH INFORMATION...CONTINUE...WW 307...WW 308...WW 309...WW 310... AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 70 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 26035. ...Smith Read more

MD 0968 CONCERNING TORNADO WATCH 311... FOR SOUTH-CENTRAL AND SOUTHEASTERN MISSOURI INTO NORTHERN ARKANSAS
Mesoscale Discussion 0968 NWS Storm Prediction Center Norman OK 0103 AM CDT Sun May 26 2024 Areas affected...south-central and southeastern Missouri into northern Arkansas Concerning...Tornado Watch 311... Valid 260603Z - 260800Z The severe weather threat for Tornado Watch 311 continues. SUMMARY...Storms continue moving eastward across central and southern Missouri and now, portions of far northwestern Arkansas -- within WW 311. As storms continue eastward, new WW issuance is anticipated. DISCUSSION...Latest radar loop shows strong/locally severe storms, including a pair of supercells (one crossing Polk and Dallas Counties in Missouri and the other over Delaware County Oklahoma and moving into Benton County Arkansas), moving eastward into/across the Ozarks area. Downstream from these storms, RAP-based objective analysis shows a favorably unstable airmass to the southwest of a warm front that roughly bisects Missouri from northwest to southeast. Given the available warm-sector airmass, and favorably strong/veering flow with height indicated across this region, it would appear that severe risk will continue to expand downstream from WW 311 over the next 1 to 2 hours, likely warranting new WW issuance. ..Edwards.. 05/26/2024 ...Please see www.spc.noaa.gov for graphic product...
