Discussion... 
stage still appears to be setting up for a very busy few days 
with respect to severe weather across Oklahoma and western North Texas. Large 
scale western trough will bring several shortwaves into the 
Southern Plains through Tuesday before main trough moves through. 


For today... capping inversion has held things in check... but 
midday sounding across the area show only minimal cap still 
remaining. Expect storms to develop across western Oklahoma into 
western North Texas and with extreme instability and strengthening 
wind fields... severe storms are likely. 


Another round of severe weather is anticipated on Sunday with the 
main surface boundaries residing farther east and southeast in the 
main body of the state with afternoon storms developing in western 
Oklahoma and more likely affecting central sections of 
Oklahoma. Again instability and wind fields will be very 
favorable for high end severe storms. 


The latest model runs have slowed the eastward progression of surface 
boundaries down and keep much of central into eastern Oklahoma in 
the risk on Monday and perhaps even into Tuesday across southeast 
Oklahoma. The particulars will become increasingly dependent on 
what happens the day/night before. 


Otherwise very warm/hot and muggy conditions will continue the 
next several days before the surface front works through the area with 
some cooler and drier air working into Oklahoma and North Texas.
