DISCUSSION

BE ISOLATED. THURSDAY A COLD FRONT WILL PROGRESS ACROSS THE
FORECAST AREA BRINGING ANOTHER ROUND OF SHOWERS AND STORMS.
AGAIN,
STORMS WILL BE CAPABLE OF WETTING RAIN, BUT THERE WILL BE
LIMITATION IN AREAL COVERAGE.
DRY CONDITIONS ARRIVE THROUGH SATURDAY NIGHT. LIGHT WINDS WITH
LIMITED MIXING EXPECTED FRIDAY AND SATURDAY, BUT CONDITIONS ALOFT
AND AT THE SURFACE WILL BE QUITE DRY. ANOTHER COLD FRONT NEARS
SUNDAY WITH SOME SHOWERS, AGAIN PROVIDING LITTLE WETTING RAIN
CHANCES. HIGH PRESSURE THEN MOVES INTO THE REGION EARLY NEXT WEEK
THROUGH MIDWEEK.
