which basin are you talking about? when I hear "basin", I immediately think Reno (i.e. Great Basin).
in terms of the weather I endured, yesterday we had a quick burst of heavy rain somewhere between 2 and 3 pm over on Carson Pass and then it was clear on the drive all the way back to Truckee, albeit thunder clouds were accumulating. probably around 6 pm (give or take) we had another burst of rain in Tahoe/Donner accompanied by thunder, but it lasted less than 10-minutes. haven't heard/seen any reports from elsewhere (i.e. Squaw/Alpine/Tahoe City, etc).
the one thing i have been observing is that these recent storms in the Tahoe area are really micro-climatized. for example, when I-80 flooded down near Verdi on Tues it was clear and balmy in Tahoe/Donner. we've had other recent storms where it was clear in Truckee but raging hail at Kings Beach.
