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.
