.DISCUSSION...Isolated thunderstorms will redevelop over the higher
terrain again this afternoon and evening. Lightning on dry fuels
that have reached or exceeded the 90th percentile ERC values is the
main concern, but any thunderstorms that develop will be capable of
erratic, gusty winds and brief heavy rain as monsoonal moisture has
been brought into the area from the Southwest. Drier conditions will
develop on Friday.
Forecast for 20 foot wind speed (valleys and ridge tops) are 10
minute averages reflecting RAWS winds.
