.DISCUSSION...
Light winds are going to be the biggest challenge today. We are
expecting primarily a westerly direction but speeds will be very
light so could see local directional shifts of at least 60 degrees
to the north or south at times. Other than that expect sunny skies
and min RH values in the 20s by late afternoon. If you have any
questions call us at 952-361-6671. Have a great day.
