For the forecast, a cold front moved onshore early this morning bringing heavy to moderate precipitation in a Southwest flow aloft. The front will weaken as it moves East and we should see light precipitation by this evening as it exits our zone. Freezing levels will slowly lower to about 1800 meters this evening but should remain above most of the local peaks for the better part of the day. A strong upper level ridge will develop over the Pacific for Saturday bringing unsettled conditions with cooler temperatures. The FL should drop to around 1600 meters for Saturday as the flow becomes Northwesterly. Sunday into Wednesday looks mostly sunny with the possibility of some cloud development on Monday. FL were forecasted to drop but that has changed and it looks like the air mass will be fairly warm through the sunny weather. We may get some inverted temperatures. Guesstimates: 15-25 mm of precipitation by Saturday morning. We may see 3-5 cm at 1650 meters by tomorrow morning.

Yesterday a brief cooling occurred and we received 4 cm at 1650 meters. The temperature there dropped to +.5 between 13:00-13:30 Hours.
