The Big 90?

Update 1:29 PM: Blogger images are now working.  NAM figure added.

Remember that long wet, cool spring?  It's over.  Summer arrived yesterday and Mother Nature is turning up the heat.

By tomorrow, 700-mb temperatures over Salt Lake are forecast by the NAM model to hit +15C, which should give is a high of about 90.

The heat will give us a serious pulse of runoff, including in the Cottonwood Canyons.  Little Cottonwood, for example, is expected to approach flood stage tonight (Wednesday night) and peak tomorrow night.
