MD 0470 CONCERNING TORNADO WATCH 115… FOR CENTRAL/EASTERN IOWA
Mesoscale Discussion 0470 NWS Storm Prediction Center Norman OK 0910 PM CDT Tue Apr 04 2023 Areas affected...Central/Eastern Iowa Concerning...Tornado Watch 115... Valid 050210Z - 050315Z The severe weather threat for Tornado Watch 115 continues. SUMMARY...Severe threat will continue beyond watch expiration. New Severe Thunderstorm Watch will likely be issued by 03z. DISCUSSION...Warm-advection thunderstorms have generally lifted north of ww115 as the warm front advances north ahead of the approaching short wave. Primary concern for convection the next several hours will be along the advancing cold front where the convective mode is becoming linear dominant. While isolated supercells will continue along the line, and perhaps ahead of the evolving squall line, it appears the main risks will now be hail/wind. New ww will likely be issued by 03z (before expiration) to account for this threat. ..Darrow.. 04/05/2023 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...DVN...DMX...
