August heat gets the heave-ho!

It’s been a brutal summer for heat. It started with the 3rd hottest June on record.

August 2010 (through the 23rd) is also running among the top 3 hottest on record.  Those are 1952, 2010, and 1951 in that order.

Of course, with milder weather here, this year will probably drop down in the list. Based on my projected temperatures through the end of August, (highs 88-93, lows 64-72) we'll still wind up somewhere between 6th and 10th hottest, but probably below August of 2006 which was the 4th "toastiest" in record books.

Now, we’re seeing a welcome change with mild air moving southward. A large bubble of Canadian air will dominate much of the Plains for several days. It’s behind the "strongest" front to move through in three months.
 
The "strength" of the front refers to the temperature difference across it. Highs will run in the 80s and 90s with lows in the 60s. Some upper 50s are possible in the cooler locations of southern Oklahoma Thursday and/or Friday morning!
 
Surface moisture will begin to increase over the weekend, but a return to 100-degree readings is not in the outlook through the end of the month. Why? The upper high which made the past month so hot is weakening and moving away. Also, a deeper southerly flow should allow for more clouds and a daily chance of showers beginning Sunday.
 
Although daily record highs remain over 100 through much of September, the odds of seeing 100-degree weather decrease with each passing day this time of year. The sun is getting lower in the sky and we're losing two to three minutes of daylight each 24 hours. Since we will not have the pronounced sinking motion under the high (which heats the low-level air), it's unlikely we'll have any more triple digit heat, at least for a while.
 
The pattern evolving for this week will provide us a nice little preview of early fall. I hope that you enjoy..I know I will.
 
Take Care,
