Valid 132209Z - 132345Z The severe weather threat for Severe Thunderstorm Watch 102 continues. SUMMARY...A multicell cluster of storms may produce occasional wind damage into early evening. Local extension in area of WW 102 is possible, but additional watches are not expected. DISCUSSION...A cluster of multicell storms continues east near the Indiana/Michigan border. Recent observations show max convective gusts in the low 40 kt range. Water vapor imagery shows modest shortwave ridging over this area which has lead to marginal effective shear values. Downstream of this activity, dewpoints have mixed down into the upper 50s F. The current expectation is for this cluster to continue to produce occasional damaging winds with a general decrease in intensity/organization with time. The strongest activity may remain on the southern flank where dewpoints are slightly higher. While local extensions of WW 102 may occur, additional watches are not expected at this time. ..Wendt.. 04/13/2026 ...Please see www.spc.noaa.gov for graphic product...

Valid 132246Z - 140015Z The severe weather threat for Tornado Watch 103 continues. SUMMARY...A favorable corridor for tornadoes will exist along the warm front over the next 2-3 hours. As additional storms form this evening, storm interference may eventually modulate the tornado threat. Large to very-large hail is also possible. DISCUSSION...A favorable corridor for tornadoes exists along the warm front from west-central Wisconsin into central Wisconsin. Here, low-level shear will be maximized and will likely increase early this evening as 850 mb winds intensify. The strongest storm is currently along the Goodhue/Wabasha County line. This storm poses the greatest threat for large/very-large hail and tornadoes in the near term. The main question will be whether a storm can become dominant and move along the warm front. There will likely be a window during the next 2-3 hours where this is possible. Beyond that time, increasing low-level warm advection will probably promote additional storms and storm interactions will make the tornado risk less clear. ..Wendt.. 04/13/2026 ...Please see www.spc.noaa.gov for graphic product...
