9:30pm Heat Update

I would agree with those of you below talking about the warm night ahead.   I can’t believe it’s 9:45pm and the temperature at our station is still 89 on the roof!
This may be the warmest/muggiest night many of us have ever seen in Portland.  What could be more "perfect" for a warm night?  A record high temp, then thick cloud cover arrives immediately following peak heating.  Plus the dewpoint is well into the 60’s now.  So I’m forecasting 72.  Our RPM model shows about 76.  Of course the all time record is 74 at PDX, so this will be one of the warmest nights ever in the metro area. 
I dropped tomorrow’s forecast to 97, assuming that the cloud cover would be pretty persistent through midday.  If it breaks up quickly, we’ll be back to 100.  The radar looks impressive this evening, but there’s hardly any rain reaching the ground.  In fact there have been NO lightning strikes in Oregon today or this evening.  All moisture appears to be above 10,000′.
Not much cooling Sunday, then a pretty good push Monday to put us back down to 90 or so.  That should feel much more comfortable.
