With one half of 2009 in the record books, temperatures are running just about normal for the year so far. At BWI-Marshall, we have had 3 warmer than normal months and 3 cooler than normal months, leaving us just a few hundredths of a degree above the 30 year (1971-2000) average temperaature for January through June. And, there are no signals of an extreme weather patterrn in sight for the next 90 days. The outlook from NOAA’s Climate Prediction Center is calling for “equal chances” or warm or cool weather for July through September, and “equal chances” of wet or dry weather for the same time period.
