FORECAST:

A weak trough is exiting with a weak ridge building for unsettled weather in a North Westerly flow aloft. The freezing level could easily reach 2000 meters today dropping back down to 1500 meters by tonight. Low will send a weak trough for tomorrow with periods of light precipitation starting later in the am into Saturday morning. A more vigorous trough pushes onshore Saturday morning with light/moderate precipitation and cooler temperatures. A little less rain on Sunday as the cool wet pattern continues into early next week. Guesstimates: 0 mm by Friday morning, 1-3 mm by Saturday morning, 5-20 mm by Sunday morning.
