KEY MESSAGE

- DRY FOR MOST OF THE AREA THROUGH THE WEEK WITH ABOVE NORMAL
TEMPERATURES CONTINUING.

ISSUED AT 246 AM EDT MON SEP 14 2026
A FRONT NEAR THE OH RIVER TONIGHT WILL PUSH SOUTHWARD AND CROSS OUR
AREA DURING THE DAY. IT WILL HAVE LITTLE IMPACT ON OUR SENSIBLE
WEATHER, AS WARM TEMPERATURES WILL PERSIST BEHIND IT FOR THE NEXT
FEW DAYS DUE TO A LARGE MID/UPPER RIDGE ACROSS THE REGION. DEWPOINTS
MAY BE A LITTLE LOWER BEHIND THE FRONT, IN THE MID 60S TO LOWER 70S,
WHICH MAY HELP KEEP THE HEAT INDEX BELOW ADVISORY VALUES. SOUTHERN
AND CENTRAL VALLEY LOCATIONS ARE EXPECTED TO SEE HEAT INDEX VALUES
OF 100 TO 105 TODAY AND TUESDAY.
RAIN CHANCES WILL BE LOW THROUGH THE WEEK, AND MAINLY FOCUSED ALONG
THE HIGHER TERRAIN OF THE MOUNTAINS AND SW VA. THE UPPER RIDGE MAY
SHOW SIGNS OF WEAKENING AROUND THE WEEKEND, WHICH COULD ALLOW FOR
SOME BETTER RAIN CHANCES EARLY NEXT WEEK.
