Cobb winter weather forecast

Cobb is not included in a winter storm watch that has been issued for northeast Georgia, but we’ll be getting a blast of wet and cold weather this weekend that could turn for the worse by the start of the week.

A winter weather system is moving into Georgia and metro Atlanta later Friday that could bring several inches of rain.

For starters, the National Weather Service has issued a flood watch from 7 a.m. Saturday to 7 p.m. Sunday for a good bit of Georgia, including Cobb. We’re expected to get at least a couple inches of rain, with chances for wintry precipitation on Saturday and Sunday evenings.

Areas of Northeast Georgia are already under a winter storm watch with temperatures expected to dip below freezing. Between 1-2 inches of snow is being forecast, as well as possible accumulations of ice.

Cobb and metro Atlanta are not included in that storm watch for now, although low temperatures Saturday and Sunday are forecast to be in the mid- to low-30s.

Cobb government spokesman Ross Cavitt said Cobb DOT crews have run exercises this week to refine routes and trucks are preparing to lay out brine and clear roads if necessary.

He also said Cobb Emergency Management is monitoring  conditions should road closures be necessary. 

They’re posting updates on the Cobb government Facebook and Twitter accounts.

UPDATE: Shortly after 4 p.m. today, Cobb schools sent out a message saying it also would be monitoring weather conditions, and “will update Cobb parents and staff multiple times over the weekend” on social media outlets.

Cobb schools post those updates on the district’s Facebook and Twitter accounts.

They’re also asking that parents check and update e-mail preferences with their childrens’ schools to receive those messages.

It’s almost exactly a year ago today that we had an unexpected winter storm in Cobb, with several inches of snow and several days of school cancellations.

Here’s more from a special weather statement issued by the National Weather Service this morning:

At this time, the best chance of seeing measurable ice accumulations will be north and east of a Homer to Gainesville to Dawsonville line. The rain-freezing rain line could move as far south and west as Canton to Cumming to Lawrenceville to Winder to Athens, where a mix of rain and freezing rain is possible.

Outside of the winter weather threat, across parts of north and middle Georgia, heavy rain Saturday into early Sunday could result in up to 3 inches of rainfall. This will likely elevate the threat for localized flooding or flash flooding.

Sunday night into Monday, wrap-around moisture in the colder air behind the system could result in some light snow showers across portions of north and central Georgia.

The chance of rain is around 90 percent Saturday and 50 percent on Sunday.

High temperatures are expected to be only in the low 40s on Saturday and the mid 30s on Sunday.

Similar weather is forecast for the start of the week on Monday. By Tuesday, the sun may come out a little, and fully sunny skies are in the forecast for the middle of the week.

Cobb winter weather forecast: chance of light snow starting Tuesday afternoon

NWS Forecast Map

UPDATED, 5:30 p.m.

The National Weather Service has issued a winter weather advisory for Cobb and most of north Georgia that begins at 4 p.m. Tuesday and continues through 7 a.m. Wednesday.

Cobb and Marietta are included in an area outlined in white in the map below, at right, that could get up to an inch of snow, starting late Tuesday afternoon. In addition, temperatures are expected to fall between five degrees above zero to zero Tuesday night and into Wednesday morning, in what the NWS refers to as wind chill values at “dangerous levels.”

In addition to really having to bundle up again—below freezing temperatures are back, along with wind chills that will make it feel like it’s in the single digits—there’s a chance of light snow for Cobb, metro Atlanta and most of northwest Georgia Tuesday afternoon.

The National Weather Service has issued a special weather statement that up to an inch of light snow is possible across an area above a line from LaGrange to Conyers to Commerce
as early as Tuesday afternoon and into Wednesday morning.

While Tuesday’s daytime highs could reach into the 50s, it’s in the late afternoon and evening hours that the precipitation is most likely to occur, and temperatures are expected to plunge into the high teens in metro Atlanta.

Wednesday’s temperatures are not expected to reach freezing, with lows also in the teens. Skies will be sunny, but the wind chill factor will linger at least through Wednesday.

Here’s more from the NWS advisory, which was issued early Monday morning:

Although forecast amounts will mainly be less than 1 inch, temperatures will be well below freezing Tuesday night. Any snow that falls, no matter how light will likely remain on the roads and ground through Thursday morning.

Low temperatures Wednesday morning will range from 12 to 20 degrees with wind chill readings from 10 above to near zero.

Temperatures are expected to drop into into single digits, so any snow that falls will stick.

We will update this forecast if it changes, which the NWS said is likely, including possible school closures.

The weather will get warmer for the weekend, with highs in the 50s and possibly even into the low 60s on Sunday, when a light chance of rain is in the forecast.
