Brihat Samhita
स्तनितं निशि विद्युतो दिवा रुधिरनिभा यदि दण्डवत्स्थिताः । पवनः पुरतश्च शीतलो यदि सलिलस्य तदाआगमो भवेत् ॥ २८-१२ ॥
If there is thunder at night, lightning by day appearing blood-red and standing upright like a staff, and if a cool wind blows from the front, then the coming of rain is to be expected.
