.DISCUSSION...

A weak high will nudge into northwest Wisconsin today, while a
broad low develops over the eastern Dakotas. This will bring more
sunshine than clouds at the burn site this morning. Cloud cover
will increase as the day progresses. Winds will be southwesterly
through the day. The mixed layer will grow this afternoon and
expect gusts of 10-15 mph. There may be occasional gusts of up to
20 mph at times. Expect minimum relative humidities between 40-45
percent. Highs will be in the mid to upper 70s. The best
opportunity for showers and storms is tonight as the low slides
into the region. A few diurnally driven showers could develop this
afternoon near or over the burn site, however confidence in this
particular outcome is quite low due to the high nudging in.

Shower and thunderstorms will move in tonight and chances will
continue through much of Wednesday as the broad low moves through.
