MD 1952 CONCERNING TORNADO WATCH 640... FOR NORTHERN NEBRASKA AND SOUTHEASTERN SOUTH DAKOTA
Mesoscale Discussion 1952 NWS Storm Prediction Center Norman OK 0807 PM CDT Tue Sep 10 2019 Areas affected...Northern Nebraska and southeastern South Dakota Concerning...Tornado Watch 640... Valid 110107Z - 110230Z The severe weather threat for Tornado Watch 640 continues. SUMMARY...Thunderstorm activity may evolve into an increasing organized cluster which could pose increasing potential for strong wind gusts, mainly east-northeast of Valentine NE toward the Sioux Falls SD area, between 10 PM and Midnight. A new severe weather watch will likely be issued, replacing tornado watch 640 and severe thunderstorm watch 642 before their 10 PM expiration. DISCUSSION...Vigorous thunderstorm development is now largely focused within the zone of stronger lower/mid tropospheric warm advection, to the cool side of the surface front, across northwestern and north central Nebraska into southeastern South Dakota. Through 03-04Z, a southerly low-level jet is forecast to continue intensifying (including 30-50 kt at 850 mb) across the central Plains, with associated strongest forcing for ascent becoming focused near or just east of Valentine NE. As this concentrates inflow of seasonably moist air supportive of large CAPE, a corridor of renewed intensifying and organizing convective development appears possible, which may be accompanied increasing potential for damaging winds. This is then expected to shift into the Sioux Falls SD by 05-06Z, if not before. ..Kerr.. 09/11/2019 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...FSD...OAX...ABR...LBF...UNR...
