...MOISTURE INCREASING LATTER HALF OF WEEK INTO NEXT WEEK...
.BROADCAST DISCUSSION...High pressure will strengthen across
the region into Wednesday bringing a warming and drying trend.
Monsoon moisture will spread back into the region for the latter
half of the week, bringing showers and thunderstorms along with
cooler temperatures and higher humidities.
.DISCUSSION...High pressure over the area will continue to bring
warm and mostly dry conditions over the area through Wednesday.
Increasing moisture for the second half of the week and into next
week will then bring an increasing threat of showers and
thunderstorms to the area. Isolated high-based showers and
thunderstorms will be possible as early as Wednesday, with gusty
microburst winds the main threat. Then, expect a gradual
transition to scattered to numerous coverage and mainly wet
thunderstorms by the weekend and into next week.
***Thunderstorms imply strong, gusty and erratic winds***
***All winds are 20 foot, 10-minute averages***
