Guidance still shows good continuity/agreement for the overall
pattern. Expect moderate to brisk trades during the period with
strongest winds during the weekend when high pressure to the
northeast of the state is strongest. The pressure gradient will
gradually relax from Monday onward as the westward-drifting
surface high weakens somewhat. An area of enhanced moisture
accompanied by an upper level weakness crossing the area provides
some increase of windward/mountain rainfall along with showers
occasionally straying to leeward locations today. Guidance
consensus shows a drier trend for the weekend. Models and
ensembles show an area of lower heights aloft slowly passing
through around Monday-Thursday. This could lead to a some rebound
in showers, but precipitable water values should be modest.
