.DISCUSSION...

Clear conditions to start out this morning will become
increasingly cloudy by early afternoon as a system will bring rain
showers and isolated thunderstorms for northeastern Minnesota.
Precipitation onset may be delayed or only sprinkles as the rain
fights to overcome the dry air near the surface as minimum RH dips
down to the mid to upper 20s. Nevertheless, showers and
thunderstorms are expected in the vicinity of the burn site this
evening and into overnight tonight.

Skies will clear throughout the morning on Sunday and will lead
to even lower RHs in northeastern Minnesota, with widespread low
20 percents and isolated areas reaching into the teens. Winds will
also increase out of the northwest at 10-15 mph with gusts up to
20 mph. While currently marginal, if the forecasted winds trend
any higher, a Red Flag Warning may be needed for Sunday.
