The upper level ridge will bring mostly sunny skies to the area today with a Northwesterly onshore flow. There is still some scattered high cirrus cloud but it should burn off by this afternoon. The FL is just below 4000 meters and there is a slight inversion. The high pressure will  persist into Tuesday before a rapidly approaching upper trough pushes in from the North by Tuesday night. We should see come cloud development Tuesday afternoon and there is a chance of some precipitation early Wednesday morning. The FL will drop to 1500 meters by Tuesday night as the trough moves through, with some moderate/strong winds in the alpine. Wednesday will be mostly cloudy with some scattered showers and the FL will gradually rise back up to the 2500 meter range. Unsettled weather for Thursday as the trough moves East and a ridge begins to build for the end of the week.
