1256 PM GMT WED SEP 17 2025
DISCUSSION
FOR THE MOST PART, CONDITIONS CONTINUE TO BE HOT AND DRY. SHOWERS
EXPECTED TODAY HAVE BEEN RATHER SLOW TO DEVELOP, BUT ISOLATED
SHOWERS AND THUNDERSTORMS WILL STILL BE POSSIBLE WITH DAYTIME
HEATING THIS AFTERNOON.
HOT AND DRY CAN BE EXPECTED FRIDAY AND SATURDAY WITH LITTLE TO NO
RAIN CHANCES ANTICIPATED. DAYTIME RH VALUES IN THE 30 TO 50
PERCENT ARE EXPECTED. AREA KBDI VALUES HAVE NUDGED INTO THE 600S+,
MAKING FIRE WEATHER DANGER AN INCREASING CONCERN IN THIS DRY
PATTERN. HOWEVER, WINDS ARE ALSO VERY LOW WHICH IS KEEPING THE
THREAT RATHER CONTAINED AT THIS TIME.
