…AREAS OF FOG TO CONTINUE INTO FRIDAY MORNING…

VISIBILITIES OF GENERALLY ONE MILE OR LESS HAVE BEEN OBSERVED ACROSS MUCH OF SOUTHERN IOWA THE PAST SEVERAL HOURS. THESE REDUCED VISIBILITIES WILL OCCASIONALLY DROP TO ONE HALF MILE OR LESS AT TIMES AND CONTINUE FOR THE REST OF THIS EVENING. RELATIVELY DRIER AIR WILL BE ADVECTED INTO IOWA OVERNIGHT WHICH SHOULD HELP LIFT THE FOG BY SUNRISE FRIDAY.

BE PREPARED FOR REDUCTIONS IN VISIBILITY…ESPECIALLY ACROSS LOW LYING AREAS. SLOW DOWN AND ALLOW EXTRA SPACE BETWEEN YOURSELF VEHICLES IN FRONT OF YOU.
