Today was the first real chase day that showed some potential for severe storms. A thermal trof was swinging in from the west and coupling itself with a cold front descending from North Dakota into Eastern Nebraska. The best lapse rates were right on the nose of warm air where there was a southeasterly wind field. The biggest problem at the time was a lack of good 500mb support but otherwise bulk shear numbers were set to rise as the day progressed.
