While much of the west coast has been breaking record highs left and right (Portland, Seattle, Spokane),  We here in the east have been dealing with the exact opposite… Chilly temperatures!  The numbers are in for the month of July and while we got close… we were just off of the mark for the number one spot of coldest July on record.

Here are the numbers from Dayton….   The numbers are a little different from what we were posting about a week ago, the records however have now been corrected.

1.  69.2  1947

2.  69.6  2009

3.  69.9  1984

4.  71.6  2007

5.  71.9 2000

Over all this July came in as the second coolest on record.  The reason for it… a large east coast trough, you can see it in the picture below.

With the jet stream to our south cooler air from Canada has had an easy time getting down into the Midwest and Northeast.  While this pattern will continue to hold firm this week… there are a few bubbles that will briefly push the jet northward for a few days.  The first will come on Monday and Tuesday allowing temperatures to get to about average.   The second will take place Friday and go into the weekend.  Right now it looks like some of the warmest air this season could push numbers as high as the lower 90s by the time Saturday and Sunday roll around.  Of course forecasts can change… but it looks like some August heat is on the way.
