GARDENERS & GROWERS:

Freeze Warning / Growing seasons in the Inland Northwest: 

Freeze Warnings are typically issued by the National Weather Service

when freezing temperatures are expected during the growing season,

which is defined as the dates between the average first freeze and last

freeze dates for a geographic area. However, every growing season is

different, so it's possible Freeze Warnings may be issued outside of the

usual growing season. For example if the first 3 weeks in April are

unusually warm and free of any freezes in the Spokane Area, then a

freeze warning may be needed prior to May 1st if freezing temperatures

are expected.
