.DISCUSSION...Dry surface low pressure begins to push into the
region tonight and Saturday morning. This feature will have little
impact except on the winds. Winds will weaken as the center of the
low/trough nears central SD. Winds will also slowly shift to the
southwest and then west by around noon. Drier air in place will
keep the burn site from reaching full recovery in humidity tonight
or through the weekend. High temperatures on Saturday could range
between 84 and 88 degrees which would push RH down around 20
percent.
