.DISCUSSION...
Sunny skies in store today. Expect northeast 20-foot winds around
9-12 mph with gusts up to 18 mph today and fair smoke dispersal at
ignition time increasing to good to excellent this afternoon.
Afternoon minimum relative humidity drops as low as 35-38%.
Surface high pressure and calm winds tonight is expected to allow
stout near-surface inversions to form and highly limit any smoke
dispersal right after sunset today. Scattered rain chances build
late Friday morning into the remainder of the day. Scattered
thunderstorms are expected to form Friday afternoon, and an
isolated strong thunderstorm can`t be ruled out during the late
afternoon into mid evening, with small hail and localized erratic
wind gusts as the main threats. Localized rainfall amounts of one
to two tenths likely, though slightly higher under any storms.
South to southwest winds Friday morning veer northwesterly by
mid-Friday afternoon, with 20-ft gusts increasing to around 15
mph during the afternoon. Minimum afternoon RH values will be
slightly higher, bottoming out around 40-45%.
