.DISCUSSION...
WARM AND SUNNY WEATHER TODAY AS HIGH PRESSURE MOVES THROUGH
SOUTHERN MINNESOTA. SOUTH WINDS AROUND 7 TO 12 MPH. TODAY...GOOD
MIXING AND SCANT MOISTURE BEING TRANSPORTED TO THE BURN SITE WILL
CONTRIBUTE TO LOW RH VALUES...A MINIMUM NEAR 20 TO 25 PERCENT IS
EXPECTED. A CONCERN TODAY IS THAT WITH DAYTIME MIXING RH VALUES
MAY DROP LOWER...AS SUCH A RH MINIMUM NEAR 15 PERCENT IS POSSIBLE.
SMOKE DISPERSION WILL BE VERY GOOD.
