134 ACUS11 KWNS 032228 SWOMCD SPC MCD 032228 KSZ000-COZ000-032330- Mesoscale Discussion 1525 NWS Storm Prediction Center Norman OK 0528 PM CDT Wed Jul 03 2024 Areas affected...east-central CO into far northwest KS Concerning...Severe Thunderstorm Watch 501...502... Valid 032228Z - 032330Z The severe weather threat for Severe Thunderstorm Watch 501, 502 continues. SUMMARY...The greatest risk for significant severe hail between 2-2.5 inches is anticipated through about 7 PM MDT over east-central Colorado near the I-70 corridor. An increase in severe wind potential is expected towards the northwest Kansas border. DISCUSSION...A pair of slow-moving supercells between Denver and Limon will have the greatest potential to produce large hail beyond 2 inches over the next 2-3 hours. These storms will move towards the peak buoyancy plume characterized by MLCAPE of 1500-2000 J/kg along the CO/KS border area. With favorable westerly speed shear above 2 km AGL per the FTG/PUX VWP data, in conjunction with a modest increase in low-level south-southeasterly flow in the next few hours, intensification of these supercells is plausible. This will also include a risk for increasing severe wind gusts, as persistently indicated by recent WoFS guidance. ..Grams.. 07/03/2024 ...Please see www.spc.noaa.gov for graphic product...
