Another cold blast is on its way into the Lowcountry, with the cold front arriving this afternoon. Temperatures will make it back to about 60 before brisk west winds kick in and start bringing colder Arctic air into the area once more. Precipitation will be light at worst with the smart money saying we’ll stay dry. The incoming dry air along with gusty winds will elevate our fire danger this afternoon; please don’t burn outside if you don’t have to. Gusty winds may also cause some travel issues on the bridges with gusts to 40 MPH possible; NWS has a wind advisory for us for said strong gusts from 1 to 7 PM.
Here’s the temperature trend over the next few days:

Expect lows in the 20s starting Wednesday morning; Wednesday and Friday, we’ll be lucky to break 45. Things start to rebound on Saturday.
The forecast does not necessarily show the degree of dangerous cold we had on January 7-8; however, strongly consider taking similar cold weather precautions each night starting tonight: drip a faucet, bring in pets, and check on loved ones (especially the elderly).
Wind chills in the teens will also be a factor Wednesday and Friday mornings, so bundle up at the bus stop appropriately:

If you’re further inland or in a more rural area, things may be a little cooler than advertised here; alternatively, the closer to the coast you are, the warmer you’ll be (albeit not by much; NWS is still advertising upper 20s for lows in downtown Charleston).
As far as sensible weather goes, don’t expect much in the way of precipitation for the next several days with a very dry airmass in place.
