Questions
Is this the same as the Reading the Sky ebook?
No. The flip guide is a quick field reference drawn from the ebook. The ebook explains the science behind every number and warning sign. See the full ebook (coming soon).
Can I print it on regular paper?
Yes. If your printer cannot feed index cards, print on letter paper at actual size and trim each card to 5 × 3 in.
Do I need to be an experienced chaser?
No. The cards are written for weather hobbyists and new chasers. Pair them with free NWS SKYWARN spotter training before your first season.
What if I lose my download?
Your download link is in your purchase receipt email. If you cannot find it, contact us and we will resend it.
Be ready before the next chase
16 cards. One PDF. Instant download.
The flip guide is an educational reference, not a substitute for National Weather Service watches and warnings. Storm chasing is dangerous; you are responsible for your own safety.
