Mesoscale Discussion 1860 NWS Storm Prediction Center Norman OK 0630 PM CDT Wed Aug 07 2024 Areas affected...Central High Plains Concerning...Severe Thunderstorm Watch 611... Valid 072330Z - 080130Z The severe weather threat for Severe Thunderstorm Watch 611 continues. SUMMARY...Hail and wind threat will spread east with convection this evening. DISCUSSION...Water-vapor imagery suggests a weak disturbance may be encouraging upscale convective growth over the central High Plains early this evening. Upper anticyclone remains positioned over the Great Basin and northwesterly 500mb flow should strengthen a bit over northeast CO into western NE tonight. Scattered robust convection is gradually increasing in areal coverage as it propagates downstream into somewhat more buoyant airmass, especially along/south of the synoptic front that currently extends across the NE Panhandle into southeast WY. Prefrontal wind shift is also aiding convection across northeast CO and this activity should gradually advance toward northwest KS later this evening. Several supercells are noted within the larger convective complex, but mixed storm mode should linger for several hours before possible MCS evolves over northeast CO/southwest NE after sunset. ..Darrow.. 08/07/2024 ...Please see www.spc.noaa.gov for graphic product...
