...MOISTURE CONTINUES TO INCREASE...
.BROADCAST DISCUSSION...Monsoon moisture will continue to increase
across the area through at least early next week, bringing increasing
coverage of showers and thunderstorms. The storms will be initially
on the dry side, with increasing chances of wetting rains by
the weekend, particularly beginning Sunday.
.DISCUSSION...The state will stay under southerly flow over the
next several days as high pressure parks itself over the Four
Corners region. This will act to draw monsoonal moisture
northward. The increase will be gradual at first, with a more
pronounced surge late in the weekend. This will bring increasing
relative humidity values, decreasing temperatures, and increased
coverage of showers and thunderstorms. The moisture will initially
be high based, with gusty and erratic winds remaining the main
threat today before wetting rains become more likely this weekend.
Model guidance continues to suggest that the moisture will peak
by the middle of next week.
***Thunderstorms imply strong, gusty and erratic winds***
***All winds are 20 foot, 10-minute averages***
