In Grandview and, more broadly, across the state of Washington: The rest of the day will feature mostly cloudy skies with temperatures ranging from the low 40s to upper 50s. Light southeast winds at around 3 mph, with occasional gusts up to 5 mph, will add to the cool feel. There is a chance of light rain, with total accumulation around 0.08 inches, and the highest likelihood of rain occurring during this period. Overall, it will stay quite mild in temperature, but the cloud cover and light rain could make it feel a bit damp and chilly. No significant wind is expected, so conditions should remain relatively calm throughout the afternoon.
