WEATHER FRONT is a solid example of the tried-and-true theme type, "revealer pointing to first words." It's a broad category, with many variations, such as BEGINNING OF FALL (words that can precede FALL), FRESH START (synonyms of FRESH), and OPENING DAY (themers starting with days of the week).
I enjoyed the fresh phrases Kyra chose, CLOUD STORAGE a modern term. THUNDERBIRDS is fun, and seeing LIGHTNING BUGS is always a highlight of visiting my in-laws in Indiana.
I wondered if CLOUD, THUNDER, and LIGHTNING were apt WEATHER terms, though. The WEATHER forecast calling for rain or snow, yes, but THUNDER (not thunderstorms?)? A lonely CLOUD? These sky phenomena do fall into the WEATHER category, but it felt loosey-goosey.
Loved so many of the bonuses! EONS AGO sings. MORONIC is a word I (and others) use to describe myself. DRAGONs are fun. Even BOTOX and PRISM spruce things up.
Three potentially tougher terms to mention:
I love the word KVETCH (Yiddish, for complain). Several friends of mine were baffled by a Yiddish puzzle I co-constructed, though, so that's given me more pause about putting it in early-week puzzles. Lest the kvetching feedback continues.
DMING is not D-Ming, the Democrat from Mongo. (DM-ing, or direct messaging — social media shorthand.)
As a finance guy, I'm more tolerant than others to terms like ETAIL and IBANK, because they're common finance lingo. I wouldn't trust any online bank that calls itself an EBANK, though.
I would have loved more grid flow out of the NW corner, perhaps by moving the three black squares above DMING to the right. That would have opened up a juicy long slot in DMING's place, too.
All in all, a fairly smooth Monday solving experience, if not that sharp an a-ha moment. Wish I had caught the progression — reading Kyra's thought process did help elevate my impression.
