...INCREASING MONSOONAL MOISTURE...
.BROADCAST DISCUSSION...Increasing monsoonal moisture over the
area into next week will bring increasing coverage of showers and
thunderstorms and increasing RH. The storms will be initially on
the dry side, with increasing chances of wetting rains by the
weekend, particularly beginning Sunday.
.DISCUSSION...Increasing monsoonal moisture statewide will be the
main story of the entire 7 day period, with a secondary surge of
moisture arriving Sunday. Coverage of showers and thunderstorms
will therefore gradually increase each day, with an associated
increase in cloud cover, especially after Sunday. While gusty and
erratic outflow winds are the main threats for today and tomorrow,
as moisture increases and storms trend wetter, expect increasing
chances for wetting rains instead. Additionally, minimum and
maximum RH will increase by around 10 percent between Sunday and
Monday as that secondary surge moves in, with still a gradual
increase thereafter. Model guidance suggests the moisture peaks
around Wednesday, though this may still vary moving forward.
***Thunderstorms imply strong, gusty and erratic winds***
***All winds are 20 foot, 10-minute averages***
