RESULT IN ISOLATED TO SCATTERED SHOWERS NEAR THE LOW MAINLY ACROSS
WESTERN PORTIONS OF THE STATE. FARTHER EAST CLOSER TO THE

PRESSURE WILL BE AN INCREASE IN CLOUDS AND PERHAPS A BRIEF
SPRINKLE.

WINDS WILL BE TRICKY WITH A LIGHT NORTH WIND AT THE
PRESCRIBED BURN SITE REPORTED...AND A SOUTHWEST WIND AT THE ROLLA
