SUNNY CONDITIONS. TEMPERATURES ARE EXPECTED TO CLIMB EACH DAY WITH
HIGH TEMPERATURES IN THE MID NINETIES BY THE END OF THE WORK WEEK

INFLUENCE OF AN UPPER RIDGE. THE AIRMASS WILL START OFF DRY BUT BY
LATE IN THE WEEKEND SOME MOISTURE WILL MOVE INTO THE FORECAST AREA
FROM THE SOUTHWEST. AREAS OF MOISTURE WILL CONTINUE TO FLOW THROUGH
THE UPPER RIDGE WHICH COMBINED WITH DAYTIME HEATING WILL LEAD TO

PRECIPITATION BEGINNING MONDAY THAT ARE CLOSE TO CLIMATOLOGICAL
