Heat wave backs down briefly only to come roaring back

Main relief less hot and more comfortable mornings by Sunday

More record heat but then...

SOME relief is on the way as I’ve been advertising for days now, but it’s only relative to the extremes we are having now and it won’t last long at all before the heat ridge flexes its muscles again next week. Most obvious will be nicer morning lows Sunday/Monday. But then the heat wave comes roaring back.

In my prior tweets and blogs back to June 4th I stated the above-normal heat looked like it would last into at least early July and that still appears to be the case, BUT at least it looks like more normal summer heat for July/August at times, so not every day will be in the mid or upper 90s thank goodness.

However, there does not yet seem to be any real period of significant below-normal high temps through the rest of the summer.

UNLIKE most of the past 3 years true summer heat is back in business with help from the Pacific La Nina, the Global Wind Oscillation/Global atmospheric angular momentum and the Madden Julian Oscillation. (GWO), (GLAAM or AAM), (MJO).

Meanwhile the rain chances (hit or miss storms) continues low the next couple days, then the chance goes way down for an extended period of days and it looks like below-normal rainfall on average through the end of June.

500mb JET STREAM PATTERN AND THE HEAT DOME RIDGE:

Moisture in the atmosphere goes from steambath to more normal values briefly by Sunday:

Look at the HUGE DROP in dew points (measure of moisture in the air that impacts humidity) between now and late Saturday-Sunday/Monday:

But that slight reduction in temperature and the lower humidity does not last, as the 500mb heat ridge makes a comeback next week with more record threatening heat:
