Sunday humid with scattered showers.

A broad ridge to our north continues to maintain easterly trade flow over us (surface animation). In the upper levels a trough dives south approaching our island (200mb animation). Recent model runs have trended farther west with the trough axis placing us in deeper moisture (700-300hPa moisture) with some low and mid-level converging winds helping to fuel windward showers. There doesn't appear to be much cold air associated with this event, which reduces the risk of thunder. Nonetheless deep moisture approaches 2" at times and this could fuel some heavier showers, especially with the favorable (easterly) wind direction.
