With sufficient model agreement on ascent and available moisture, increased POPs to categorical. Another trough rapidly advancing from the Upper Midwest should maintain shower chances Tuesday night and Wednesday with it`s approach and passage. Temperatures are expected to average 10 to 20 degrees above seasonal levels. && .LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/...
