.DISCUSSION...

Very brief periods of drizzle remain possible through 10 AM this
morning, though measurable rainfall (>0.01") is very unlikely
today. Otherwise, cloud cover should slowly diminish into this
afternoon, with light winds turning from northerly to
east/southeasterly towards sunset.

More impactful weather is expected on Tuesday. While relative
humidity is expected to remain >30-40% at the burn site, gusty
southerly winds (up to 40 mph) are expected from the mid-morning
through evening. There is also a medium (30-50%) chance for a
thunderstorm from the early evening hours into Wednesday morning.
Any nearby thunderstorm(s) will introduce potential for gusty/erratic
winds and heavy rainfall.
