FORECAST:

The offshore low will send a vigorous front our way in a Southwest flow aloft. Light precipitation with periods of moderate precipitation, strong winds and the FL hovering in the 1200 meter range hopefully dropping to 1000 meter with the trailing edge of the front. Lingering cloud on Sunday with periods of light precipitation and the FL spiking to 1600 meters. Ridge appears to rebuild for Monday into Tuesday before another weak front pushes through on Wednesday. Models are still in disagreement for early next week so stand by for a better forecast as we get closer.
Guesstimates: 8-12 cm by Sunday morning, 1-3 cm by Monday morning.
