.DISCUSSION...

Conditions Saturday will be slightly warmer as a weak warm front
moves through the Northland. As a result, chances for showers
continue into Saturday at the burn site. Accumulations, however,
are expected to be light - up to 0.1". Chances for thunderstorms
is little to none, as the best environment for general
thunderstorms will likely remain south of Highway 2. As the low
pressure to the west approaches, initially gusty easterly winds in
the morning will taper off through the afternoon.
