If the weather gets warmer while the barometer is high and the wind northeasterly, we may look for a sudden shift of wind to the south. On the other hand, if the weather becomes colder while the wind is southwesterly and the barometer low, we may look for a sudden squall or a severe storm from the northwest, with a fall of snow if it be winter time.
A sudden rise of the barometer is very nearly as dangerous as a sudden fall, because it shows that the level is unsteady. In an ordinary gale the wind often blows hardest when the barometer is just beginning to rise, directly after having been very low.
A rapid rise of barometer indicates unsettled weather. A slow movement the contrary, as likewise a steady barometer, which, when continued, and with dryness, foretells very fine weather.
