short-term weather forecast system

The author is located in an area with a lot of convective weather and hot and humid weather. I stared at it silently, and saw that the clothes to be dried came in and out five or six times a day... Weather forecast on the mobile app? Weather warning text message? It can only be regarded as a late report. I am lazy, do it myself, have enough food and clothing...
