is ahead if the wind is from your left and better weather if the wind is from your right. Knowing these basics of wind flow will never take the place of a good weather map and the information we get from the National Weather Service, but it can be helpful when the forecasts are all going sour.
             The strength of wind flow is governed by how much the barometric pressure changes within a given distance. As they tell you in basic meteorology, the closer the isobars are to each other, the stronger the wind. Strong winds mean the highs are very high and the lows are very low.
             Air assumes the properties of the area over which it flows: Warm air comes form the south, cold air from the north. Moist air comes from over water, dry air from over large land masses. The vigor with which the wind blows is an indication of how much moisture, or how much dry air, is overspreading the area. Winds in the middle and high levels tell the meteorologist a lot, too.
