...MOISTURE INCREASING THROUGH MIDWEEK...
.BROADCAST DISCUSSION...Monsoon moisture will continue to increase
across the area through at least Wednesday, bringing increasing
coverage of showers and thunderstorms, improving humidity, and
higher chances for wetting rain, particularly early next week.
.DISCUSSION...Monsoon moisture will continue to increase across
the area through the middle of next week. The increase today will
be subtle, but more substantial for Sunday into Monday. This will
bringing increasing coverage of showers and thunderstorms, a
greater likelihood of wetting rains, and improved relative
humidity values. There is a chance that lingering cloud cover will
limit the coverage of convection on some days, particularly after
Sunday. Current thinking is that the amount of moisture will peak
Wednesday with a slow decrease thereafter.
***Thunderstorms imply strong, gusty and erratic winds***
