A WEAK SYSTEM WILL BRING A SLIGHT CHANCE OF RAIN SHOWERS AND THUNDERSTORMS TO
SOUTHERN AREAS SUNDAY AND MONDAY. OTHERWISE, HIGHER PRESSURE WILL GRADUALLY
BUILD IN ACROSS THE SOUTHERN HALF OF THE STATE THROUGH MIDWEEK. THIS WILL BRING
WARMER TEMPERATURES, RISING TO NEAR OR SLIGHTLY ABOVE NORMAL BY MIDWEEK. STORM
SYSTEMS WILL PASS THROUGH SOUTHERN CANADA THROUGH THE WEEK, KEEPING
TEMPERATURES COOLER WITH BREEZY CONDITIONS AND OCCASIONAL RAIN AND HIGH
MOUNTAIN SNOW SHOWERS NEAR THE CANADA BORDER. A WEAK SYSTEM MAY BRING COOLER
TEMPERATURES AND INCREASED WINDS TOWARD THE END OF THE WEEK ACROSS THE SOUTH,
BUT CONFIDENCE IS LOW.
