Show Know The Weather Why does a cold front often arrive unexpectedly, without warning? Does it move faster than its counterpart, the warm front? A COLD front often speeds along at 23 to 33 miles an hour and gives no high-in-the-sky advance notice, as do the cirrus cir-rus clouds of a warm front. This is because the cold front, unlike the warm, arrives on the surface before it passes over you nign aoove. Its leading edge slants backward. back-ward. Therefore, the first notice you may have is one of gusty, chiller winds, and often the cold front produces short, intense showers followed by colder, and clear weather. COLD FRONTS arrive all through the year and don't necessarily produce precipitation. precipita-tion. In summer you may notice nothing other than a cooling of the weather. This usually means a cold front has passed unnoticed, bringing with it more pleasant and usually drier air. In winter, the fronts bring with them cor- . respondingly colder weather, as would be expected. , |
