...EXCESSIVE HEAT WARNING IN EFFECT UNTIL 10 PM PDT WEDNESDAY...

.DISCUSSION...
No major changes to the pattern through Monday as strong high
pressure aloft continues to bring hot and dry conditions to
the fire, capable of producing large vertical plume growth
during peak heating hours.  Winds will follow a typical
upvalley/downvalley diurnal pattern. The highest winds are
expected during the afternoon and early evening hours, with
southerly/upvalley winds 5 to 10 mph and gusts up to 18 mph
possible. Low humidities will continue on Sunday, with a slight
uptick likely on Monday. A slight influx of mid level moisture
may bring some afternoon cloud buildups near the fire. By
Tuesday and Wednesday, there is a slightly better mid level
monsoon moisture surge, bringing a 10-20 percent chance of
thunderstorms to the eastern San Gabriels. At this time,
it appears that that main risks with any new thunderstorms
would be isolated dry lightning strikes and gusty outflow
winds.
