.DISCUSSION...

Good morning,

While relative humidities shouldn`t fall as low as they did
yesterday, there may still be a few hours where we drop down below
Fire Danger Criteria. Minimum RH this afternoon will be around
25%. Luckily we`re expecting RH values to climb in the next day or
two as winds become more southerly and a weak front approaches.
This will mark the beginning of a less dry period that will run
through the rest of the week.

Winds will start light and variable this morning and pick up late
this morning out of the south but remain less than 5 mph.

Please let us know if you have any additional concerns or
questions!
