Thunder and lightning last night, more next Sunday?

We had a decent convective line plow through here just after midnight last night, providing the first thunder and lightning of the 2010 season. Given the above graphic for next Sunday there may be potential for a chase that afternoon. The model graphic shows us to be in the warm sector of a system that is poised to send a cold front blasting through the region that afternoon. The upper level support seems to be pretty far north, but if enough moisture and temperature contrast is available we could see some convective storms (crossing fingers...).
