and early afternoon hours. Surface winds will shift to a westerly
direction during the mid to late afternoon hours. Westerly
transport winds will strengthen this afternoon, creating good
dispersion values. Surface winds will shift to northwest to

overnight as a cooler and drier air mass filters over our region.

not expected through this weekend.
