SLOW MOVING CONVECTION PRODUCING TORRENTIAL RAINS OF 2+ INCHES/HR NOW DEVELOPING ON NOSE OF MODEST 20-25KT LLJ ACROSS SOUTHWEST PORTION OF THE CWA. ISENTROPIC LIFT/WAA WILL PERSIST THROUGH MIDDAY WHILE 850MB 20-30KT JET WILL TRAVERSE THE CWA AFTER SUNRISE. THIS IS DUE IN PART TO THE UPPER WAVE THAT IS SAGGING SOUTHEAST INTO THE REGION.
