MOISTURE TO RETURN TO THE AREA TODAY...WHICH SHOULD BE SUFFICIENT
FOR ISOLATED HIGH BASED SHOWERS AND DRY THUNDERSTORMS AROUND THE
AREA THIS AFTERNOON AND EVENING. GUSTY ERRATIC WINDS CAN BE
EXPECTED NEAR THUNDERSTORMS OR AREAS OF VIRGA. THIS SOUTHWESTERLY
FLOW IS EXPECTED TO SURFACE THIS AFTERNOON AND BECOME THE DOMINANT

THUNDERSTORMS MONDAY AFTERNOON THROUGH EARLY EVENING.

IN THE WAKE OF THIS SYSTEM...HIGH PRESSURE ALOFT IS FORECAST TO
STRENGTHEN ACROSS THE REGION DURING THE MIDDLE TO LATTER PORTION
OF THE UPCOMING WEEK. THIS WILL RESULT IN WARM AND DRY CONDITIONS
