4/15/2013 Frost Warning
Continued Cold Temperatures on Tuesday and Wednesday Mornings
Time Period High risk: Tuesday and Wednesday mornings Low to Moderate Risk: Thursday morning Low risk: Friday morning and beyond
Locations Affected Much of central and eastern Washington, and possibly colder areas of western Washington like Olympia and Sequim.
Temperatures Low to mid 20s in colder locations to the 30s in warmer areas.
Cold weather will continue to promote areas of frost in central and eastern Washington on Tuesday and Wednesday mornings.
During this time, lows will average in the upper 20s to mid 30s in central and eastern Washington. The potential exists for widespread critical temperatures, especially on Wednesday morning, although not all locations will experience critical temperatures. It appears that areas of clouds and wind may keep Tuesday morning temperatures similar to Monday morning. Despite a warming air mass, increased stability should allow Wednesday morning to be similar to, or slightly colder than Tuesday morning.
While periodic clouds and wind will keep some areas in the 30s, clear and wind-sheltered areas are likely to drop into the mid to upper 20s each night and morning. The potential exists for the coldest areas to drop into the low 20s.
Milder temperatures on Thursday morning suggest safe conditions in many areas, although a chance of isolated frost will persist in the colder parts of the Yakima Valley. From Friday morning and beyond, generally safe conditions are expected with much warmer weather.
Please continue to monitor AgWeatherNet for weather forecast updates during this variable and critical time period. The Frost Risk page is updated daily, and additional frost risk detail will be available in the Friday outlook.
