.DISCUSSION...All of the data is pointing to it has been one of
the hottest, driest and windiest periods on record for this time
of year. Tomorrow there is a chance for dry thunderstorms, but the
coverage of lightning may be isolated. Although any showers that
develop will be capable of producing strong outflow winds with a
good portion of the area below 15 percent RH in the afternoon. On
Friday the coverage of showers and storms increases. Chance of
wetting rain is possible for the higher elevations, while dry
lightning and gusty outflows winds may still be possible for lower
elevations. Chances for afternoon showers continues into the
weekend, but we need to see what happens tomorrow and Friday to
access the threats.
...GUSTY ERRATIC WINDS CAN BE EXPECTED NEAR ANY SHOWERS
OR THUNDERSTORMS...
