Forecast
Last Week's Data
Forecast: We continue to be protected by the west coast ridge of high pressure that has produced our hot summer, and dry winter last year. Right now we are just about at the edge of the ridge. This means Pacific storms are passing by near the Canadian border.
For Shoreline and Lake Forest Park, I am expecting sunny days, morning clouds at times, and cool nights. As the ridge fluctuates through the next week we may have increased cloudiness on a couple days, Monday-Tuesday area, and again around Friday.
We may see some rain showers return next weekend, but forecasts are not agreeing with each other on anything past 4 days out so it's pretty uncertain right now. I will post an update if there is any significant changes in the forecast. Temperatures will probably average in the 60's for highs, mid-low 50's for a low. Some days might see 70°F for a short time in the late afternoon.

Last week's data:
High temperature: 67.8°F (Sunday)
Low temperature: 46.9°F (Friday)
Rainiest day: 0.54 inches (Monday)
Total rainfall: 0.54 inches
Warmest day: 57.2°F (Saturday)
Coldest day: 55.1°F (Sunday)
Average temperature: 55.7°F (Historic average: 55.5°F)
Below are two temperature graphs. In the first one you can tell where the first day of fall is. The average temperature went from a fairly level average to a sudden drop after about the 22nd of the month. I never noticed this before, but even the station historic average shows that same drop. I never realized how stable September was relative for temperature right up until the first day of fall. The second graph shows the daily low and daily high temperatures compared to the station's average for September. Six days in September were above 80°F for a high temperature. The interesting aspect is the low temperatures. You can see a low temperature heat wave from September 16th through about the 28th.
