Another shot of Intense Heat for next week

I like to try to focus the forecast generally a week out from the given date so for this post, I would like to talk about next week. Next week is going to be hot...probably the hottest weather we have had all season. As we head towards July, if the temperature at 5000 feet above sea level is 20 degrees for example, and its Sunny(Not overcast) and its July or Late June, you can add 15 additional degrees to that and forecast your temp on the surface. For Example, The 00z European model run has for next Wednesday at 7pm 850mb(5000 feet) temps at about 20.2. Since its Late June, if you tack on 15 to the 20.2..you get 35.2. 35.2 C at 7pm is 95 degrees. At 7pm! So what is it going to be at 3pm? Well the shorter term more high resolution models can break it down by the hour but I'm guessing Next Wednesday, We will see temps near 100 degrees. Here is a chart courtesy of (www.wxrisk.com) that gives a good general rule of thumb of how to use the 850mb temps to make your forecast.



So next week, its going to be hot again for probably Tuesday,Wed and Thur before it cools down again. I dont see much rain in the next couple of days but in the summer, there is always a chance for a late day shower or TStorm
