Climate Watch
Wednesday, November 11 - After unseasonably mild weather a week ago, this past week ending November 7th saw a return to somewhat cooler temperatures across southeast Michigan. The average maximum temperature for the week was 51.9F, the average minimum temperatures was 33.8F and the total precipitation was 0.04 inches. These conditions were a tad bit cooler than the climatological averages for the period: 52.6F for the maximum temperature and 36.3F for the minimum temperature. While our cooler than average conditions persist, at least we have experienced some relatively dry weather across the area.....a welcome site after having passed our annual average rainfall total several weeks ago! The melted equivalent precipitaiton total for the year to date is 36.78 inches (annual average = 35.43 inches). There were 150 heating degree days last week, given us a year-to-date total of 4883.
The Climate Prediction Center is suggesting that our mild weather is not over yet, with above average temperatures a good possibility heading into the week of Thanksgiving. Additionally, the CPC indicates that our El Nino conditions continue to strengthen, with Sea surface temperatures (SST) at least 1.0ºC above-average across much of the central and east-central equatorial Pacific. The also note that based upon current observations and model forecasts, this El Niño is expected to continue to strengthen and last through at least theNorthern Hemisphere winter 2009-10. This typically means mild temperatures.....time will tell.
