SHOULD QUICKLY REBOUND WITH MOST LOCATIONS SEEING HIGHS IN THE
70S TODAY. OVERNIGHT LOWS LOOK LIKE THEY'LL STAY WARM ENOUGH IN
MOST LOCATIONS FOR WEDNESDAY MORNING. ALTHOUGH THERE COULD BE A
FEW SPOTS ACROSS THE UPPER SNAKE PLAIN THAT COULD SEE SOME
PATCHY FROST. TEMPS RISE TO NEAR 80 IN ACROSS MOST OF THE SNAKE
PLAIN AND EASTERN MAGIC VALLEY ON WEDNESDAY. MEANWHILE, A LOW
PRESSURE SYSTEM WILL WORK INTO THE PACIFIC NORTHWEST. THIS
SYSTEM WILL LIFT MONSOONAL MOISTURE INTO OUR REGION FOR
WEDNESDAY THROUGH FRIDAY RESULTING IN SHOWERS AND STORMS. THE
