DISCUSSION
HIGH PRESSURE WILL BUILD IN THROUGH TUESDAY. ANOTHER COLD FRONT
LOOKS TO DROP IN FROM THE NORTH WEDNESDAY BRINGING THE NEXT CHANCE
FOR SHOWERS AND A FEW THUNDERSTORMS. THE FRONT WILL CROSS BY
THURSDAY BEFORE RETURNING NORTH LATE IN THE WEEK.
MUCH COOLER TEMPERATURES ARE EXPECTED THROUGH TUESDAY WITH A
MODERATING TREND IN TEMPERATURES EXPECTED DURING THE MIDDLE AND
SECOND HALF OF THE WEEK. WINDS WILL BE ON LIGHT SIDE STARTING
TONIGHT THANKS TO HIGH PRESSURE OVERHEAD, BUT HUMIDITIES WILL BE
MARGINALLY LOW TO NEAR CRITICAL LEVELS. THE NEXT POTENTIAL FOR
RAINFALL IS WEDNESDAY INTO THURSDAY, BUT AMOUNTS LOOK LIGHT AGAIN.
