4/22/2013 Frost Warning
Cold Temperatures on Tuesday and Wednesday Mornings
Time Period High risk: Tuesday morning Moderate risk: Wednesday morning Low risk: Thursday morning and beyond
Locations Affected Much of central and eastern Washington, and possibly colder areas of western Washington like Olympia.
Temperatures Low to mid 20s in colder locations to the 30s in warmer areas.
Stable conditions will promote areas of frost in central and eastern Washington on Tuesday morning. Despite warming temperatures aloft, clear skies and less wind than this morning will allow temperatures to drop into the mid 20s in colder locations on Tuesday morning, with 30s expected elsewhere. In general, Tuesday morning should be slightly colder than Monday morning, with strong inversions present. Areas that are most likely to be colder tomorrow morning relative to Monday morning are low lying areas of south central Washington such as Moxee. Some areas in north central Washington from the Wenatchee area to the Okanogan, as well as many slope and hilltop regions, may experience similar or even warmer conditions tomorrow morning.
Areas of frost are expected again on Wednesday morning in the colder areas, although conditions will be warmer than Tuesday morning, and the frost coverage area will be notably less. Milder temperatures on Thursday morning suggest safe conditions for most if not all areas. While there is a chance of increased frost risk by next Sunday or Monday morning, it is too early to say with confidence at this point.
