PATCHY EARLY MORNING FOG WILL BE POSSIBLE AGAIN TODAY, BUT IT SHOULD
BE MAINLY NEAR RIVERS AND LAKES.
A LARGE UPPER RIDGE TO OUR WEST WILL GRADUALLY SHIFT EASTWARD DURING
THE PERIOD AND SURFACE HIGH PRESSURE TO OUR NORTH AND NORTHEAST WILL
EXTEND INTO OUR AREA, KEEPING OUR WEATHER DRY INTO EARLY NEXT WEEK.
MODELS SUGGEST THE UPPER RIDGE MAY BREAK DOWN AND SOME MODELS HAVE A
FRONT APPROACHING BY MID WEEK, BUT EVEN THEN MOISTURE LOOKS VERY
LIMITED AND THUS WE HAVE A DRY FORECAST FOR THE ENTIRE PERIOD
THROUGH WEDNESDAY.
FOR THE ENTIRE PERIOD WE CAN EXPECT COOL NIGHTS AND PLEASANT
AFTERNOONS WITH HIGH TEMPERATURES EACH DAY NOT FAR EITHER SIDE OF
SEASONAL NORMALS. WE WILL ALSO SEE LOW RELATIVE HUMIDITY VALUES
DURING THE AFTERNOON HOURS.
