Great summary and chase account with forecast maps by Skip Talbot<\/a><\/p>\nA potent spring-time upper-level trough was approaching the High Plains from the west, providing excellent mid-level winds and the shear necessary for severe storms. \u00a0Surface low pressure was near Hays, Kansas, with very nice dew points of 68F-70F just east and northeast of the surface low. \u00a0Even better, an E-W outflow boundary due to morning convention near the KS\/NE line was stalling out across north-central KS. \u00a0Low clouds were still in place north of this boundary during the early afternoon as we headed south from Red Cloud into Kansas. \u00a0The main difficulty for this forecaster was where to play east-west along this boundary. \u00a0SPC seemed to heavily favor areas east of U.S. 81\/I-135. \u00a0Tornado risk percentages were 10-percent (hatched) from Salina to Topeka and Kansas City, whereas the area around the surface low, near Hays, was pegged at less than 5%. \u00a0There was also the dry line through central KS and OK to consider, but surface winds were much more favorable for tornado development along this outflow boundary in northern Kansas. \u00a0I directed the group southward through Lebanon and Tipton into the mid-afternoon, and we broke out of the stratus overcast as we neared Hunter on Route 181. \u00a0I had decided that this area along the boundary and just northeast of the surface low would be a satisfactory target area. \u00a0We drifted south of Hunter a couple of miles into the sunshine and warmer temperatures. \u00a0There was nothing important bubbling up yet, so we went back into Hunter to poke around and kill some time.<\/p>\n
