Observe plants carefully
Getting down on your hands and knees to take a closer look at grass, flowers, fungi and pine cones can give clues to the oncoming weather. Look for these particular signs:
Check grass for dew at sunrise. If it is dry, this foretells clouds, strong breezes and possible rain. But if dew is present, chances are it won’t rain. If it rained during the night, then obviously this method will be unreliable.
Some plants fold up their flower petals before a rainfall. Dandelion, clover, tulip, morning glory and chickweed are among this sensitive group.
Blooms tend to be more fragrant before a rain
An increased growth of mushrooms, moss and lichens indicates moist weather
Oncoming stormy weather winds can make the leaves on trees flip and toss and show their undersides
Pine cones have long been used as an indicator of precipitation. They change shape according to how much moisture is in the air. When the air is dry, the cones open up, but return to their normally closed-up shape as moisture increases.
