Weather update: Monday – January 15, 2024
From Monday to Monday night: cloudy. Light to moderate snow at times. Snow will be mixed with some sleet across north Georgia. Snowfall amounts could total 2-4 inches across the northwestern half of the News12 viewing area including the Cumberland Plateau generally along and north of the line from Winchester and Monteagle to Whitwell, Soddy Daisy, Athens and Madisonville, Tennessee. In this area tonight, more snow will accumulate and snow totals by dawn Tuesday could reach the 3-5 inch range. South of this line, in a corridor running from Scottsboro, Alabama northeast through the Chattanooga metropolitan area, Cleveland and Etowah, Tennessee, snowfall totals could reach about 1-3 inches by late afternoon. This corridor will see additional snowfall accumulation tonight which could bring total amounts to around 2-4 inches by dawn Tuesday. Points south of this “middle corridor” from around Fort Payne, Alabama northeast through Lafayette and Dalton, Georgia to Ducktown, Tennessee and Murphy, North Carolina may see only a light dusting of accumulating snow later in the afternoon with a prevailing mixture of sleet, rain Freezing and snowing for most of the day before turning to snow in the evening. In this southern region, temperatures should finally cool enough for all of the precipitation to be snow as totals could reach about an inch by 7 a.m. EST Tuesday. Highs: Mainly in the upper 20s to lower 30s. However, farther south across parts of Hamilton, Bradley and Polk Counties in Tennessee and the lower elevations in Cherokee and Clay Counties in North Carolina, as well as southern locations including DeKalb County, Alabama across much of northern Georgia should be warm in the mid-30s. For a brief period around midday, before temperatures gradually drop below freezing in the late afternoon and early evening. Wind: northeasterly 5 – 10 knots per hour.
Tuesday: It will be mostly cloudy in the morning, becoming mostly sunny by mid-afternoon. Highs: Mid to upper 20s. Wind: North 10-15, with gusts up to 20 mph, bringing wind chill indexes down to 10-15.
Overnight: Mostly clear. Perishing. The lowest ranges from 5 to 10 degrees. Wind: northwesterly 5-10 mph. The combination of temperature and wind will create wind chill indices between zero and minus 5 by dawn Wednesday.
Wednesday: Sunny and very cold. Highs: upper 20s to lower 30s. Wind: Northeasterly, speed of 5 knots per hour, becoming light and volatile in the afternoon.
Overnight: Clear. Another very cold night. Minimum temperatures range from 15 to 20 degrees. Wind: South 5 mph.
The winter storm will create dangerous driving conditions across the region today through Tuesday morning and soft spots will remain through Wednesday with temperatures remaining below freezing in much of the region. Please drive carefully when heading to work and if you must travel for other reasons. High temperatures will be mainly limited to the upper 20s and lower 30s today while lows will drop to between 15 and 20 degrees by Tuesday morning. The bone-chilling cold air mass will only warm into the middle and upper 20s by Tuesday afternoon and wind chill values will drop into the single digits as healthy northerly flow develops on the north side of the departing storm system’s surface trough. Tuesday night will be a true “polar night,” with temperatures expected to drop to around 5 to 10 degrees. However, with northwesterly winds of 5 to 10 mph, wind chill indices will drop to near zero and lower!
Also, don’t forget the possibility of another southerly push of Arctic air into the region, after a short break in the movement on Thursday. Computer models forecast that more Arctic air will invade the region late Friday night into Saturday. At this time, Arctic air will remain in place throughout the entire weekend, according to the latest computer modeling solutions.
But wait! Before this cold air returns to the area, there will be a chance of a mix of rain and snow later Thursday and into the early morning of Friday. While precipitation amounts appear to be lower with this system, temperatures should be cold enough to transition to full snow Thursday night into Friday morning. This can be another problem for traveling late in the work week!
The Climate Prediction Center’s 8-14 day forecast from Tuesday, January 23 to Monday, January 29 features above normal temperatures and above normal precipitation during this period.
“Short-term and long-term drought conditions improved this week across the Southeast, associated with the passage of two storm systems. Category 1 improvements were widely warranted from the central Gulf Coast northward into the southern and central Appalachians, where many locations received more than 2 inches of precipitation this week. However, despite the heavy rainfall, the long-term deficit remains largely intact, especially in northern parts of Alabama and Georgia, where many locations are still experiencing a precipitation deficit of more than 8 inches. During the past six months.
