FORECAST:

A weak ridge of high pressure will bring sunny skies to our zone this morning in a Northwest flow aloft. We will likely see some cloud development this afternoon with the FL rising to 2200 meters.
Unsettled weather continues Monday through Wednesday with a weak system spilling some cloud into the area before an upper trough out of the Gulf of Alaska reaches the area on Thursday. Monday through Wednesday will see the FL rise each day to a high of 3000 meters by Wednesday. The air mass will remain fairly warm on Thursday with the arrival of the front, which is forecasted to be fairly wet. Cool showery weather will follow on Friday.
Guesstimates: looks dry for the next 4 days with the slight chance of the occasional intermittent light shower.
