Right now (9/30, Wed, 5 pm), two seeing forecasts are predicting excellent seeing from late Thursday night to Friday morning.
Clear Sky Clock says around 1 am Friday we'll see excellent seeing.
Astrospheric predicts the Flagstaff area will have excellent seeing as well starting sometime between 11 pm on Thursday and 2 am on Friday.
However, Meteoblue predicts a much more conservative average to above average seeing. I've seen meteoblue forecast .23 seeing and also some not-so-great 1.2 seeing so .53 seems to mean something like above average?
(It looks like meteoblue had some inaccurate seeing numbers for the last couple weeks. Those numbers should be multiplied by x4.)
(Later: I just learned about https://www.goodtostargaze.com and it shows seeing numbers (2.1 to 2.2 tonight) that feel a lot more accurate than Meteoblue. The free service only gives you maybe 1 1/2 nights but that will still be a useful data point.)
(Later, later: I just checked Meteoblue and it's reading in the .5's again so I don't know what to think, it seems accurate in a lot of other places in the country.)
