Thursday's weather update from WTOC meteorologist John Wetherbee

April 2, 2013 

A Canadian high pressure system is reaching southward from the Great Lakes, anchoring the lovely spring weather, which should last through Wednesday.

Temperatures are a little cooler thanks to northeast -- and later southeast -- breezes on shore. Some high clouds will start to build into the region tonight.

Storms, especially for our southern counties, are likely Thursday. The high pressure system will slide east into the Atlantic. A low pressure system is developing over the northwest Gulf. That system is triple point, meaning three different sources of energy are merging. Models are struggling to predict the system's track and timing.

So far, it looks like the low pressure system will generate a warm front that will move up the Gulf coast early Thursday, with some overrunning precipitation into Georgia. If the system follows the coast severe weather will likely form off shore. But if it tracks further inland, we could see some severe weather.

With that in mind, we need to be alert to this developing system. The good news might be that this is all done by Friday lunch, and the weekend forecast looks fabulous. We will keep you updated. Meteorologist John Wetherbee, CBM
