Scattered showers passed through North Arkansas overnight, with more significant rainfall expected to arrive today as a weather system moves in from southwest Missouri. The National Weather Service predicts that isolated areas could receive between half an inch to an inch of rain, with some locations experiencing higher totals before the system exits later this afternoon. Following the rain, a noticeable drop in temperatures is forecast. On Thursday, high temperatures are expected to reach the 80s. However, Friday will bring blustery conditions, with highs only reaching the 60s and wind gusts anticipated between 20 and 25 miles per hour. Overnight lows will fall into the 40s on Friday night. By Saturday, clear skies will persist, with highs again in the 60s. Temperatures are projected to dip into the 30s Saturday night, leading to the potential for frost in some low-lying areas early Sunday morning. Residents are encouraged to monitor changes in conditions and take precautions to protect sensitive plants in areas at greater risk for frost.
