Autumn chill returns

Temporary dip to below-normal temperatures

Another extended dry spell is on the way as we switch from a warm spell to a cool spell. But the cool spell will not be anything too dramatic and it will not last all that long.

As the jet stream goes, so goes the weather. When the jet stream goes up and a high pressure ridge develops we warm up and dry out, when the jet stream dips down South from the Northwest we cool off and dry out. The transitions are when fronts move through and can bring some rain.

Watch the jet stream pattern change. A Southwest to Northeast flow is warmer, a flow from the Northwest to the Southeast is cooler. A West to East flow is mild.

The “warm colors” are high pressure ridges and the “cool colors” are jet stream troughs of low pressure. The main jet stream flows between them along the lines:

After Sunday it looks dry the next 7 days.

Frosty temperatures will return for a few mornings, but NO hard freeze for Metro Atlanta. As expected our first official freeze of the season is running late. Our up and down pattern will continue through November.
