.DISCUSSION...Monsoonal moisture will continue to push into the
region, helping to fuel showers and thunderstorms over the next
few days. Strong outflow winds, heavy rain, and lightning will be
possible with any storms that develop. Dry lightning will be
possible across the northern and western portions of our forecast
area as the lower-levels of the atmosphere will be relatively dry
compared to the southeastern portion of our forecast area where
moisture will be more abundant. Hotter than normal conditions
will stick around for the next two days, with cooler than normal
temperatures returning next week. Outside of any outflow winds,
winds will remain relatively light through the period.
Note: Thunderstorms imply gusty and erratic winds.
