Starting this weekend a ridge of high pressure will be in place through at least Monday 9-22.  (so above normal temperatures and below normal precipitation) will tend to be the pattern. However, models indicate that the ridge weakens Wednesday 9-24 (see map below) so some cooling and chance of showers. Finally, lower confidence in forecast from 9-24 onward.
