Summary of Daily Weather Date Being Summarized: 27 May 1995 The strong trough that dug into the southern Rockies yesterday ejected into the Nation's midsection and closed off over the upper Midwest on 27 May (Sat). Overnight convection exited most of the VORTEX area by Saturday morning, allowing ample time for heating and recovery of the airmass. In fact, a warm front that sat across southern OK and northwestern TX for most of Friday lifted north into KS and MO by early morning Saturday as a surface low took shape over western KS. The dry line, which was not very strong but was present nonethe- less, punched east across all but the eastern parts of the VORTEX area during the afternoon. Surface winds veered to southwesterly across many areas ahead of the dry line, while the strongest part of the upper trough lifted across northwest KS into Nebraska during the day. The resultant lack of forcing, either aloft or at low levels, is probably why little or no convection developed in the warm sector across eastern parts of VORTEX. Some cold-core convection developed over the northwest half of the area during the day, but deep convection ended up developing well east and northeast of the eastern border of the VORTEX area. This included several strong tornadoes, described as 1/4 to 1/2 mile wide in several cases in IA. The evolution of events was fairly close to the excellent forecast made that morning by the VORTEX forecasters, which high- lighted two areas for potential development: One in eastern KS, and another potential area in eastern or southeastern OK into northeastern TX. The two areas just developed a little farther northeast than expected (Iowa and western AR). Branick
