GFS 500-mb streamline analysis
As a a result, dewpoints are elevated and we're seeing some rumblers across the state. In St. George, where some thunderstorms moved through overnight, several sites are presently reporting a dewpoint of 67ºF.
But it's a dry heat, right? Here at the U, things aren't quite so humid, but the dewpoint is still 53ºF.
For comparison, our average for this time of day in July is about 41ºF. Those of you with swamp coolers will probably find their effectiveness is lower.
With all this moisture in place, perhaps Thor, God of Thunder, will pay us a visit again tonight.
