Record Shattered

Yes indeed; yesterday's high of 101 broke the previous record high for the date of 94 degrees set in 1994. Today the bar is raised considerably; 100 degrees in 2002. Forecasts are calling for 100 degrees, so it's going to be close, especially if the clouds go away. It also depends on the barometric pressure differential through the Gorge, and therefore wind direction. Right now, it's 29.88 in Portland, 29.90 in Hood River, and 29.94 in The Dalles. Since winds flow from high pressure to low pressure, we have a slight east wind currently. This will likely shift to a west wind sometime this afternoon or evening, and bring cooler temperatures with it.

Very interesting animated cloud pattern over the Western US this morning. Moisture originating from the Gulf of Mexico and the Pacific equatorial area is streaming north and west over Oregon and California. If this continues, we could be in for some pretty dramatic thunderstorm activity.
