A surface ridge developing to the South will possibly give us a few sunny breaks in the mix later today.  The FL should top out at around 2000 meters later this afternoon. Similar day tomorrow with some light precipitation possible in the afternoon. The ridge strengthens for Sunday with warm temperatures and sunny skies. Seasonable temperatures should rebound by Monday night with the FL dropping back down to the surface with sunny skies early next week and a fluctuating FL. Guesstimates: trace to 2 m by Saturday morning, trace to 2 cm by Sunday morning.
