Made it to a high of 75 yesterday and did watch the ISS flyover last night (which was for an extended time - i.e., several minutes flying overhead). There was a very thin deck of cirrostratus, but that did not affect the viewing.
Meanwhile the heat is coming (maybe the last gasp of mid-upper 80s or higher, but we'll see). After a "warmer" low of 55 this morning, it is currently 68 and mostly sunny, with a mix of cumulus and cirrus.
