Possible Wintry Precipitation by Week's End

The cold weather that the area has experienced over the past day or so will continue throughout the area, as more arctic air makes its way into the southeastern United States. It's so cold in fact that central Florida and interior portions of southern Florida are preparing for an incredibly intense cold spell later this week. During Thursday and Friday morning, temperatures in the lower 30s(F), and possibly upper 20s(F) in some places, will be a commonplace.

The operational weather models continue to indicate a prolonged event of unseasonably cold temperatures during the next week. Even on the islands of southeast Georgia, where sub-freezing temperatures are not traditionally observed, widespread temperature readings in the 20s could be experienced. In fact, some models, namely the GFS, are showing surface temperatures below 20°F on Skidaway Island. The next low pressure system will move through the area during the same time frame, increasing surface temperatures slightly by the end of the week--Thursday and Friday. This system could result in an increase in overall moisture, and if the colder air is able to stay uniformly through the atmosphere before the bulk of the precipitation moves offshore, some type of frozen precipitation could occur. And that temperature profile of the atmosphere will ultimately determine what--if any--precipitation will result. It's unlikely that we'll see any precipitation in Coastal Empire though as model runs of the GFS, and more so of the DGEX have backed off the idea of wintry precipitation.

We'll see what happens. In the meantime, stay warm!
