HIGH PRESSURE BUILDING IN ACROSS THE REGION WILL RESULT IN A WARMING TREND IN TEMPERATURES AND DRY CONDITIONS THROUGH FRIDAY NIGHT. NORTHWESTERLY WINDS WILL DECREASE EARLY THIS EVENING AS THE PRESSURE GRADIENT RELAXES, WHICH WILL ALLOW OVERNIGHT INVERSIONS TO SET UP. WITH THAT THERE IS POTENTIAL FOR PATCHY FOG DEVELOPMENT EARLY FRIDAY MORNING OVER NORTHERN AND EASTERN ZONES, HOWEVER, IF MORE UPPER LEVEL CLOUD COVERAGE MOVES IN FROM THE WEST COMES THAN CURRENTLY FORECAST TEMPERATURES MAY NOT DROP FAR ENOUGH TO BRING SURFACE DEWPOINT DEPRESSIONS ENOUGH. FOR NOW HAVE OPTED TO INCLUDE MENTION OF FOG IN THE FORECAST FROM EARLY MORNING UNTIL SHORTLY AFTER SUNRISE FOR THESE AREAS. A SHORTWAVE WILL BEGIN TO PASS OVER THE FORECAST AREA LATE FRIDAY AFTERNOON BUT IS NOT EXPECTED TO HAVE MUCH IMPACT ON SENSIBLE WEATHER AS THERE IS VERY LITTLE MOISTURE TO WORK WITH.
