.DISCUSSION...Westerly flow expected to persist through Wednesday but
by Thursday a new low pressure system will be moving into the region
causing flow to shift and become low overnight into Thursday before
westerlies then return. This system will bring a chance of showers and
thunderstorms on Thursday, and current expectations are that moisture
with these storms will be plentiful and will help limit critical fire
starts from lightning. That being said, gusty and erratic winds near
storms could cause localized issues. With this, minimum humidities
should range around 25%, with fair to good overnight recoveries.
