THIS WAS BRINGING MOSTLY CLOUDY SKIESTO OUR PCWA AND THE CHANCE OF SOME LIGHT RAIN...MAINLY IN OURNORTHERN/NORTHEASTERN ZONES. THE UPPER LOW IS EXPECTED TO MOVE TOTHE MID-MISSISSIPPI VALLEY BY FRIDAY MORNING...AND THEN BE PULLEDTO THE NORTHEAST AS THE NEXT UPPER TROUGH SWINGS THROUGH THENORTHERN STATES. NORTHERLY SURFACE FLOW OVER THE WEEKEND THE FIRSTHALF OF NEXT WEEK WILL KEEP TEMPS GENERALLY BELOW AVERAGE. LAKEPONTCHARTRAIN SHOULD HELP TO MODERATE THE LOWS IN NEW ORLEANS ASTHE WINDS BECOME MORE NORTHERLY RATHER THAN NORTHWESTERLY. ONEOTHER CONCERN WILL BE THE FOG POTENTIAL FOR TONIGHT AS THE CLOUDSBEGIN TO SCATTER OUT. THERE MAY BE SOME PATCHY FOG...ESPECIALLY INTHE SOUTHWEST MISSISSIPPI AREA...BUT FOR THE MOST PART OUR AREA ISA FEW DAYS AWAY FROM THE SIGNIFICANT RAINFALL. THIS SHOULD HELPTO LIMIT SOME FOG DEVELOPMENT
