DISCUSSION
..TODAY-FRIDAY
GOES-WEST IMAGERY SHOWS LINGERING PATCHY FOG AND LOW STRATUS AT
THE TIME OF THIS WRITING. VISIBILITY WILL CONTINUE TO IMPROVE
THROUGH THE AFTERNOON. UPPER LEVEL RIDGING DOMINATES THE
PATTERN THROUGH THE END OF THE WEEK; COUPLED WITH THE RECENT
PRECIPITATION, FOG IS POSSIBLE THE NEXT FEW MORNINGS AS WELL,
THOUGH THE SPATIAL EXTENT SHOULD BEGIN TO SHRINK STARTING TUESDAY.
OUTSIDE OF THE MORNING FOG, SEASONABLE HIGH TEMPERATURES WITH
PERIODS OF OFFSHORE WINDS ARE EXPECTED TO CONTINUE THROUGH THE
WEEK.
..THIS WEEKEND
CLUSTER ANALYSIS AND ENSEMBLE GUIDANCE CONTINUE TO SUGGEST THE
POTENTIAL FOR THE UPPER LEVEL RIDGE TO BREAK DOWN AND FOR LOW
PRESSURE TO DEVELOP AND APPROACH THE WEST COAST. CONFIDENCE IS
BEGINNING TO INCREASE IN A MINIMALLY IMPACTFUL WEATHER
PATTERN. SOME LIGHT MOUNTAIN PRECIPITATION IS POSSIBLE, BUT LITTLE
TO NO IMPACTS ARE EXPECTED FROM THIS. BREEZY WINDS ARE EXPECTED
SUNDAY INTO MONDAY AS WELL. WE WILL CONTINUE TO MONITOR FOR ANY
CHANGES TO THIS SYSTEM, SO BE SURE TO CHECK BACK FOR UPDATES AND
FOR LOCAL FORECAST INFORMATION AT WEATHER.GOV/STO.
