Cooler-Hotter-Cooler-Hotter Update 6/23/17

After a brief warmup this week with upper 90s and a little over 100 (with wind), a significant cold front moved through this Friday morning.  Temperatures through the weekend will be some 15-25 degrees below normal!  The pattern that brought this cooler air also was responsible for the thunderstorms this week.  Quite unfortunately, the wind patterns from the surface to the higher levels were very conducive to produce supercell thunderstorms, capable of producing giant hail and wind.  There were good rains though, except that not all locations got wet.  Here is a map of rainfall during the past 7 days:

The best chance for thunderstorms with this current break in the heat will shift into southern Colorado, New Mexico, Texas and Oklahoma through this weekend.  But, then the pattern will shift north again bringing opportunities for thunderstorms into northeast Colorado, Kansas and Nebraska.  And then by the end of next week we're probably going to be back into the really hot air again.  There will be storm chances throughout the week, especially early but then shifting north with the heat.  Here is the precipitation outlook through early next Friday...

I still feel that the pattern won't get "stuck" going into much of July.  Meaning that the hot and dry will be offset by periods of cooler and chances for storms.  I'll try and get a little more detail later next week.
