Cool Start to AugustJuly 29th, 2013 at 9:19 pm by Bill Steffen under Bill's Blog, Weather
On the left is the 6-10 day temperature forecast from Monday PM from the Climate Prediction Center and on the right is the 8-14 day outlook from CPC. This map shows the probability of above average and below average temperatures. You can see the large area expected to have a higher probability of cooler than average temperatures, including all of the Great Lakes area. The maps reflect the expected trough in the East and ridge in the West. Northwest flow may take the heavier precipitation relative to average to our south, leaving us with near to below normal rainfall here in Michigan. If you get rain, consider yourself lucky. This July G.R. has had 3.05″ of rain. For 2013, we are at 30.26″ and that is 9.37″ above average for G.R. and way ahead of the 18.42″ we had last year thru July 29. With a high/low of 79/50 that puts us 7 deg. cooler than average for the day. That brings Grand Rapids down to just 4/10ths of a degree warmer than average for July.
