Southerly winds will increase ahead of an approaching cold front
on Thursday and along with the well above normal temperatures,
will lead to an increase in the fire spread potential during the
afternoon.

The combination of increasing tropical moisture and a cold front
moving into the region will bring increased rain and thunderstorm
potential and cooler temperatures late this week and into the
weekend. Locally heavy rainfall and flooding will be possible.
