        Frost Forecast!

Wenatchee and
Okanogan Districts

Time Issued:  7 PM    

Date:  Monday, April 20, 2015

Discussion for tonight:  Warm air covers North Central Washington this evening. Highs made it into the 70s - even to the lower 80s in areas - and dew points ran in the 30s and lower 40s this afternoon. Skies are expected to be mostly clear tonight and with light winds expected in most areas, strong radiation will occur and minimums are expected to vary from the mid 30s in the colder locations to the lower 50s in the warmer areas. Protection is not likely to be needed.

Discussion for Tuesday through Saturday night:  The warm spell will be coming to an end Wednesday. The warm ridge of high pressure will move off to the east tomorrow, allowing low pressure in the Gulf of Alaska to begin sending cooler air into the area tomorrow night and Wednesday. This next incoming air mass does not appear to be unusually cold, but it could cause minimums to drop to the upper 20s in the colder locations Wednesday night through Friday night. It appears help from either clouds or wind will keep most minimums in the mid 30s to mid 40s, but partial clearing at night could allow some of the cold spots to drop to the lower 30s and light protection may be needed in a few of the coldest spots those nights. Another weather front rotating around the low in the Gulf will spread clouds and light rain into the area Saturday, keeping Saturday night on the warm side.
