Rainy Tuesday, then much colder for a while
If you keep up with our daily posts, then you have known about this upcoming cold snap for quite a while. And, it's still on the way.
The first cold front approaches the Tennessee Valley during the day Tuesday. Showers beginning as early as before sunrise. Mainly scattered in nature during the morning, then the main line of heavier rain and even a few thunderstorms as the cold front moves through Tuesday Afternoon. Rainfall amounts could range from 0.75" to 1.25" across the viewing area. The risk of severe storms remains very low although some rumbles of thunder cannot be ruled out. Strong wind gusts could also accompany the front as it moves through during the afternoon providing a wind shift from the south to the north. Temperatures should be in the 50s to near 60 by late morning, then steadily fall back through the 50s by late afternoon (40s north and west)
Most of the shower activity should taper off before the colder air moves in. So, any "flurry" activity behind this front should be limited to higher elevations, mainly east. Temperatures through Tuesday Night should drop into the mid/upper 30s by daybreak Wednesday.
Cloudy and cold Wednesday with afternoon temperatures only reaching the mid 40s. Now, we will have to watch for some light precipitation trying to stream back in from the southwest starting during the morning hours. This could result in some periods of light rain/snow showers especially south from the morning and into the early afternoon. Then, some clearing into the afternoon.
A COLD & WINTRY PATTERN LOCKS IN FOR A WHILE
Successive blasts of even colder air should move in locally for late week and the weekend. Even the first flakes of the season are possible as well.
Thursday should be much like Wednesday with a mix of sun and clouds. Morning temperatures near 30 and afternoon highs in the 40s.
For Friday, a couple of things to watch. First, a stalled front south of Atlanta could allow for some overrunning precipitation to our south. For us, this should stay to our south along the I-20 corridor. But, I bring this up because this could mean a cold rain/wintry mix Friday Afternoon in the Atlanta metro and south. For us locally, more cloud cover and temperatures only reaching the lower 40s.
Now, while that chance of potential wintry weather could stay to our south, another system might bring us some flakes late Friday Night and into Saturday. A clipper system should accompany another blast of cold air for the weekend. This one even colder than the midweek blast. Clipper systems are not known for being big snow makers locally. But, enough moisture for some periods of light snow showers (wind driven too) and flurries. With limited moisture, any accumulation appears to be light and mainly at higher elevations (inch or less). But, all locations locally could potentially see flakes fly. As always, we will watch this and keep you updated....it's always a bit fun to track and report!
The bigger story with this clipper is the even colder air. Windy and cold Saturday with temperatures by afternoon rising only to the 40s, then quickly falling to the 30s before sunset. Temperatures by Sunday Morning could be in the lower 20s and even some upper 10s north. Sunday looks sunny to partly sunny with afternoon highs again only in the low 40s.
This cold spell should stick around for most of the following week providing a colder than normal first half of December, Much different than the warm patterns the past two Decembers!
