Spokane, WA – A colder weekend is approaching the Spokane area, with widespread frost expected Sunday morning, Oct. 18, as temperatures fall into the 30s across eastern Washington. The National Weather Service forecasts a low near 34 degrees Saturday night before sunshine returns Sunday afternoon. The chilly conditions could affect gardens, outdoor plants and residents preparing for early morning activities. Another round of temperatures in the 30s is expected early next week, signaling a continued stretch of cold autumn mornings.
According to the National Weather Service in Spokane, widespread frost is expected mainly before 8 a.m. Sunday, following a mostly clear Saturday night. Temperatures are forecast to fall near 34 degrees, making the early morning hours particularly important for residents with frost sensitive vegetation. While the forecast does not indicate a widespread hard freeze, temperatures near the freezing mark can still create concerns for exposed plants, especially in sheltered or low lying locations.
Weekend Temperatures Take a Noticeable Turn The approaching frost follows a substantial temperature transition. Friday is expected to reach approximately 72 degrees before Saturday's afternoon high drops to around 65. By early Sunday, temperatures could fall into the middle 30s, representing a nearly 40 degree difference between Friday's afternoon warmth and Sunday's early morning conditions.
Saturday will also introduce changing wind conditions across Spokane County. The weather service forecasts southwest winds of 11 to 16 mph during the morning, with gusts potentially reaching 25 mph. A slight chance of sprinkles is expected after 11 a.m., although the day should gradually become sunnier. Winds are expected to weaken Saturday evening as skies become mostly clear, setting the stage for colder temperatures.
Frost Could Affect Outdoor Plans For residents across Spokane and surrounding communities, Sunday's frost potential may be most noticeable before sunrise and during the early morning hours. Gardeners may want to protect sensitive plants Saturday evening, particularly those still producing late season vegetables or flowers. Bringing portable plants indoors or using appropriate coverings could help limit exposure to the coldest temperatures.
Travelers using Interstate 90, U.S. Highway 2 and other Spokane area roads should also prepare for a chilly start Sunday. The supplied forecast does not establish widespread icy road conditions or travel disruptions. However, motorists should remain attentive to local conditions, particularly in shaded areas where temperatures can differ from nearby observations.
Cooler Conditions Continue Into Next Week Sunday afternoon should bring considerable improvement, with sunshine and temperatures reaching approximately 62 degrees. The milder afternoon will offer a contrast to the frosty morning, although another cool night follows. Sunday night's low is forecast near 38 degrees, with mostly cloudy skies developing across the area.
Monday continues the relatively cool pattern, with partly sunny skies and a high near 61 degrees. Temperatures should fall near 39 degrees Monday night before Tuesday brings partly sunny conditions and a high around 60. Wednesday is expected to remain sunny with a high near 61, while Thursday's high is projected near 59. No significant storm system or widespread precipitation event is identified in the supplied Spokane forecast through Thursday.
The immediate concern remains Sunday's early frost, especially for residents with outdoor plants or activities planned before 8 a.m. Temperatures should recover during the afternoon, but cool mornings remain part of the outlook through the middle of next week.
