Administrators NorthGeorgiaWX Posted April 27 Administrators Share Posted April 27 MD 0545 CONCERNING TORNADO WATCH 145...147... FOR EASTERN KANSAS INTO NORTHERN MISSOURI AND SOUTHERN IOWA Mesoscale Discussion 0545 NWS Storm Prediction Center Norman OK 0340 PM CDT Sat Apr 27 2024 Areas affected...eastern Kansas into northern Missouri and southern Iowa Concerning...Tornado Watch 145...147... Valid 272040Z - 272215Z The severe weather threat for Tornado Watch 145, 147 continues. SUMMARY...The threat for brief tornadoes as well as damaging outflow winds and hail continues within the watch areas, and may spread east, necessitating additional watch areas. DISCUSSION...Supercells formed along a retreating boundary/warm front which now extends from northeast KS and northwest MO, and from southwest IA into southern WI. Low-level shear is maximized near this boundary with 0-1 SRH near 150 m2/s2 and weaker values into the open warm sector. Heating continues along the boundary, and the 18Z DVN sounding shows ample instability and lapse rates to sustain strong to severe storms, with generally unidirectional shear profiles. However, only minimal low-level hodograph augmentation may be necessary for a tornado risk with any supercells that move across northern MO/IA through the afternoon. As such, the threat may eventually extend beyond WW 147, and another watch and/or extension may become necessary depending on trends. Farther south into eastern KS and western MO, outflow from initial activity extends from northeast KS into north-central OK, while an unstable air mass remains just to the east. MLCAPE over 2500 J/kg as well as ample deep-layer shear will support supercells and or damaging bows this evening, with all modes of severe possible. ..Jewell.. 04/27/2024 ...Please see www.spc.noaa.gov for graphic product...
