a weak band of showers North to South over these areas. Shower
activity will diminish over these areas through Wednesday
morning. The morning lows will be coldest for the next several
days as a warming, dry trend will begin to build into the region.
The lows will be in the 30s to low 40s. the highs will be in
the upper 50s and low 70s.

Thursday through Sunday: The period will be dominated by a ridge
off the coast. The ensembles are good agreement of dry, warming
trend through the weekend. Each Day will be a few degrees warmer
than the previous before peaking over the weekend. Temperatures
are expected to average 10-15 warmer than normal by the weekend.

The Central Basin could see some locations reach into the low
90s. Overnight lows will be in the upper 40s and 50s.

Monday and Tuesday: The ridge pattern begins to flatten late
Sunday breaking the warming trend from the weekend. The ensembles
are not showing much in the way of precip. There are a couple of
