.SYNOPSIS...Last day of below normal temperatures today then a
ridge of high pressure begins to shift into the region Saturday,
strengthening through next week. This will result in dry
conditions and high temperatures warming to above seasonable
levels Sunday through next week.

&&

.DISCUSSION...Water vapor shows a trough to the south moving into
northern Mexico and Baja and a ridge building to the west in the
eastern Pacific. Saturday the trough gets absorbed into the mean
flow as it moves into central Mexico and the ridge begins to build
eastward. This will translate into slightly higher temperatures
Saturday compared to Friday with highs around normal or a degree
or two above it. Sunday through most of next week ensembles show
the ridge expanding eastward becoming centered over southern
California or just off the coast by late next week. This will
lead to positive height anomalies across the region leading to a
warmup as well as dry conditions. High temperatures will be 3-5
degrees above normal Sunday then 8-12 degrees above normal next
week. The NBM is hinting that Tucson could see highs of 80 degrees
late next work week into the weekend.
