- The week ahead
- Rainfall or the lack thereof
- Last week's weather data
For the week ahead all models seem to agree that we will have continued high pressure dominating the region. Even though we will have sunny weather it will be cool with our highs topping out in the mid 60's for the week, some days may be a little cooler than others. Our next sign of rainfall may not be until the second week of October. Of course as always with models that look that far out, there is a certain level of uncertainty and things can always change within the next 5 days.
One of the biggest questions I've gotten recently is are we below average on our rainfall this summer, and in September so far? Well to answer these questions I had to go look at some historic data and here's what I found.
- June-July-August 3-year average total rainfall: 1.97 inches
- June-July-August 2012 total rainfall: 6.89 inches (5.94 inches fell in June 2012, 4.92 inches above normal)
- July-August-September 3-year average total rainfall: 4.00 inches
- July-August-September 2012 total rainfall: 1.54 inches (2.46 inches below normal)
- September 3-yaear average total rainfall: 2.77 inches.
- September 2012 total rainfall: 0.59 inches. (2.18 inches below normal)
I wanted to point out that we have actually received more rain than
Sea-Tac (official record keeping weather station) due to a convergence
zone that developed early in the morning on September 10th, 2012.
Last week's weather:
High temperature: 71.4°F (Friday)
Low temperature: 45.7°F (Sunday)
Rainiest day: 0.08 inches (Saturday before sunrise)
Total rainfall: 0.08 inches
Warmest day: 60.8°F (Friday)
Coldest day: 53.3°F (Wednesday)
Average temperature: 56.5°F
3-year average temperature for last week: 60.3°F (3.8°F colder than normal)
Warmest and coldest days are based on average temperature of the entire
day, starting at midnight. All other averages are based on the whole
week, starting Saturday morning at midnight. All weather data unless
otherwise noted is sourced from Carl's Shoreline Weather Station.
