Winds become breezy on Wednesday and into the weekend. Daytime temperatures will be mild through this entire week. && .DISCUSSION...A very dry atmosphere, low surface dew point temperatures and nearly-calm winds tonight will set up across northern Arizona to create another round of chilly early morning temperatures for Monday. Freezing temperatures are likely again for some areas tonight, with some high country basins dropping into the low to mid-twenties. Minimum temperatures for tonight along the eastern Rim and in the White Mountains were lowered a few degrees with the evening update, otherwise the afternoon forecast package remains right on track. A warming trend and generally light winds will take hold through Tuesday to become near-normal. For the rest of the week, temperatures remain near-normal as a series of troughs pass to the north and prevent a ridge from setting up over the Southwest. Breezy southwest afternoon winds return Wednesday and last through the rest of the work week. Ensemble guidance is showing a cutoff low could set up off the southern California coast over the weekend. Confidence is low on the placement and magnitude this trough. Northern Arizona is set to see gusty southwest winds this weekend if the trend continues. && .AVIATION...For the 06Z package...Expect VFR conditions under clear skies.
