This will be a big problem in a grid down event or SHTF event. It will be scary not knowing.

One important part of everyone’s preps should be communication technology and tools. I don’t have a HAM setup, but I did manage to squirrel away a couple baeofengs and found my local repeater frequencies. I can communicate (or listen) to whats happening a couple hours West of me, and I know which way the wind blows.. HAM operators can dispense such information nationwide, so even listen-only capability should be investigated.
I use Starlink internet vs. corded options for several reasons, this being one of them. I only need my own power, to access satellite based internet (assuming the downlink stations still work). If catastrophe strikes locally, I should still have access. As we saw here during Helene, and elsewhere around the globe, its a powerful tool in emergencies.
Lastly, local, local, local. Theres one old lady in the neighborhood who controls the corn planting. “I heard the whiporwill last night” gets posted to facebook and the next morning the seed drills are out in the field. I don’t need to know when the last frost is, I just need to know when old Mrs. Johnson gives the all clear.

When weather forecasting is unavailable people will do what our grandparents and earlier generations did. Prepare for the worst and hope for the best. Without satellites weather forecasting was poor under the best of circumstances. For most of history meteorology didn’t exist.
