Summary of Daily Weather Date Being Summarized: 26 April 1995 A famous weather date in Oklahoma severe weather history again resulted in severe storms. A strong but compact upper level disturbance moved across southern Kansas and Oklahoma during the afternoon. The northwest flow system peaked in intensity during the morning as it rounded the base of the mean trof position and kicked out to the northeast. Thus, an associated surface low weakened and moved rapidly northeast during the day, allowing cold canadian air to move southeast across Oklahhoma and north Texas. A secondary low, partially generated by thermal effects (high lapse rate air in West Texas which became well-mixed to nearly 600 mb), became a weak triple point low as the front marched into North Texas. After vortex forecasters issued a forecast of possible targetable storms from Paris, Texas to McAlester, OK., 15Z and 18Z soundings indicated northward formation of a formidable cap into North Texas ans Oklahoma. Low 60 dew points made it only as far north as the Red River and southerly winds began to veer ahead of the front, adding further uncertainty to afternoon expectations. Soundings were released but the intercept mission was scrubbed by mid-afternoon. Nevertheless, the steep-sloped front caused sufficient lift to trigger two lines of storms - one from near Tulsa to Paul's Valley and Ardmore; the second one from near Jacksboro TX to Comanche, TX. A number of hail reports and at least one weak mesocyclone occurred with the Texas storm. Severe hail was also reported east of I-35 in Oklahoma. One mesocyclone triggered two tornado warnings in extreme southern Oklahoma, east of Lake Texhoma. No tornadoes were verified.
