NWS issues dense fog advisory for parts of south-central Pennsylvania
THE ECONOMY. THE MEETING RUNS THROUGH SATURDAY. IT’S 451, AND WE ARE ONCE AGAIN WARNING YOU ABOUT A FOGGY START. IF YOU’RE HEADING OUT THE DOOR RIGHT NOW. SO BY NOW, HOPEFULLY YOU ARE PREPARED TO DRIVE IN THE FOG. IF YOU HAVE BEEN DRIVING IN THE LAST COUPLE OF DAYS, WE’RE GETTING USED TO THIS, CHRISTINE. WE SURE ARE. AND I’M TELLING YOU, WE COULD SEE ANOTHER ROUND OF FOG TOMORROW MORNING WITH SOME RAIN. SO THAT’S WHAT WE’RE GOING TO BE WATCHING OUT FOR TODAY AND TOMORROW UNTIL WE CAN GET THIS FOG OUT OF HERE, UNTIL WE CAN GET SOME WIND TO STIR UP THE ATMOSPHERE AND EXCHANGE THIS AIR MASS.

IF WE HAD WINDY CONDITIONS TODAY, IT WOULD BE PRETTY MILD DAY. THERE IS WARMER AIR ALOFT AND THAT’S WHAT LOCKS THIS COLD AIR IN PLACE AT THE SURFACE AND LOCKS THOSE POLLUTANTS IN PLACE AS WELL.

I DON’T THINK WE GET OUT OF THE 30S IN A FEW SPOTS. COULD TOUCH 40 IN OTHERS. TONIGHT. WIDESPREAD RAIN, AREAS OF FOG AND LIGHT WINDS. TEMPERATURES WILL BE AROUND 34 DEGREES FOR MOST SPOTS AND THEN RISING A LITTLE BIT OVERNIGHT AS WE HEAD INTO TOMORROW MORNING, RAIN WILL BE ENDING. A COUPLE OF SHOWERS ARE POSSIBLE LATER IN THE DAY, BUT I DON’T SEE MUCH. IT WILL BE A SEASONABLE DAY WITH HIGH TEMPERATURES AROUND 42 DEGREES, SO TH
