A Quick Look Ahead; Keep Watering!

September 5, 2012

The big picture for the next 7-10 days (through mid September) looks the same today.  Just a chance for a few light showers or drizzle Sunday night or Monday morning as we get the tail end of a cold front dragging through here.   You get the idea here on the Monday morning (12z) ECMWF map:

 Otherwise, you’ll need to keep watering the lawn and garden since some sort of upper-level ridging (not sure how strong) develops over us starting next Tuesday.  The other models are similar; cool and a sprinkle/shower and then back to warm.

Here is the the 10 day rain forecast from the ECMWF.  It shows no other rain through the period, what you see there is the accumulation from Sunday night/Monday:

The GFS is pretty much dry through it’s 16 day run as well.  So the mainly dry weather continues.

An Interesting View of Climate Change

September 5, 2012

I found this nifty little climate website today.  Someone has taken NCDC climate data and turned it into easy to read graphics.  It displays overall changes in temperature and precipitation for each month since 1895. You can also see yearly and seasonal changes.

 You can change the time period and data (temp & precip) including month and seasons. 
It’s especially entertaining when you click a link on the right side of the page, it goes to the THE DAYS ARE NUMBERED blog.  Or at least that’s what showed up on my view of it.   But I came to the site just to see the maps.  Interesting to note that summers in the past 100 years have been warming in the West, but slightly cooler in the southeast USA.
Don’t miss out on my favorite part…the graph view.  Click on any climate zone (such as the Willamette Valley) and you can quickly see trends in temp and precip as a chart/graph pops up.  For example, there is no significant trend in summer temps since 1970 here in the Valley, but a little warming in the past 100+ years.
Enjoy perusing the data.
