Pictured above is the surface weather map for Thursday November 15, 2018. It shows the incipient Nor’easter storm leaving our area and heading up the Atlantic Coast. If you’ve been paying any attention at all you will have noticed how frequently we’ve had low pressure systems traveling across the deep south from Texas to the East Coast either just North of Georgia or along the Gulf Coast to the GA/SC Coasts and sometimes coming Northeast out of the deep Gulf of Mexico.
It’s almost as if mother nature is trying to tell us something about the pattern for winter.
Many of these systems have been either a “Miller A” or a “Miller B” type low pressure system (extra-tropical cyclone).
These systems usually bring Georgia bad weather, rain or snow/ice if there’s a strong wedge, and sometimes severe thunderstorms if there is no wedge or a wedge breaks down as the cold front arrives.
Our wet weather this week has been thanks to “the Millers” and our temperatures have been at January levels thanks to “wedges” (CAD events).
Regardless of what type of weather Georgia gets from one of these, they often become much stronger as they reach the Mid-Atlantic and New England states producing major wind, rain, flood, wave, beach erosion, and snow.
Depending on whether you like or hate snow or ice these type systems can be your friend or your enemy. They have been described by various NWS offices in the charts that follow. See below for examples:
Keep in mind no two Miller storm systems are ever alike. Here are some real life examples from the past:
If you read my winter forecast blog back in mid October you know I showed expected storm tracks and the higher odds for “The Millers” to visit the Southeast states in the coming winter.
Another point of origin for the Millers is just off the Texas coast:
