Synopsis...an old frontal boundary near the coast will wash out
leaving a weakness in the ridge. Next chance of rain be early next
week as moisture deepens in advance of a weak upper level trough.
Fair conditions return late Wednesday night as the trough moves
through and a zonal flow prevails. Chances for rain move back into
the forecast next weekend as a weak cold front moves to the coast.
Discussion...shaded temperatures higher today and Sunday as the
influence of middle level ridging from the northwest and surface
ridging to the east combine to increase subsidence over the area
with a lack of cloud cover. This tranquil weather pattern looks to
continue in the extended portion of the forecast as zonal flow
becomes anticyclonic in the middle and upper levels...minimizing the
effects of the frontal boundary next weekend.
