Spot Forecast for Rock Ridge SNA west...MN DNR

.DISCUSSION...
A pretty strong cold front has drifted through the Marshall and Tracy
locations, giving their winds a northwesterly direction. However all
indications that we can find, show this cold front not slipping any
further south. Therefore it is anticipated that eye level, 20 foot,
and transport winds will be out of a southwest, perhaps south southwest
by late morning. Before then, the directions could be a bit more west
to west southwest. They will become pretty breezy by midday and early
afternoon, but probably not quite as breezy as the spot location
southwest of Marshall. At this location, gusts this afternoon should
be 23 to 25 mph. Smoke dispersal will be fair to good already by
9 to 10 am. Finally, the dew points will be dry today, producing
dry minimum humidity values.
