Winter attempts a comeback this weekend
70s return for Today, but remember it is still Winter! Old Man Winter will try to remind us of that over the weekend.
*Overall thinking hasn't changed much, but models are coming in cooler*
FRIDAY MORNING RAIN/RUMBLES
A fast moving cold front moves in late tonight and through Friday Morning. This should bring a quick round of rain during the predawn hours Friday then tapering off by or just after sunrise. Rainfall amounts between .25-.50". A few rumbles are possible by the severe risk is very low. The morning rush hour could be wet, or at the very least the roads.
The drier afternoon should also be a bit breezy with temperatures in the upper 50s and low 60s.
WINTER FIGHTS BACK THIS WEEKEND
The track of a low pressure system will be the key to precipitation type Saturday Night and Sunday Morning. These are the types of systems in March that can bring a quick round of wintry weather. High temperatures both Saturday and Sunday will be above freezing, but all it takes is just enough time for the upper levels to chill to get a quick round of wintry weather. And, that is a possibility through Sunday Morning. (Sunday is also the 24th anniversary of the 1993 Superstorm - but the system we are tracking is completely different).
The forecast maps above show the NAM (North American Model) that came out around 10am. For you forecast model trackers.....yes, I have seen the other models and will watch the trends, this run is colder. But, it all comes down to the exact track of the Low pressure system. So, these models will no doubt jump around and change precipitation amounts/type in the days ahead. But, the main focus should be on the track of the system.
WHAT TO EXPECT:
- Again, a few miles and a few degrees will make a huge difference!
- Saturday should become cloudy as the system moves in from the west. Highs reaching the low/mid 50s. (Yes, the ground will be very warm).
- A chilly rain/sleet could begin late afternoon into the evening.
- Rain for some could change to snow during the late night/overnight hours. Some may start as snow/sleet
- The more favorable location locally could be the northern half of the viewing area (and mountains)-BUT this could change
- The southern half (GA/AL) may have longer a period of rain becoming a mix or changing to sleet and snow. (May stay all rain).
- This looks to be an overnight event with the system quickly moving out by Sunday Morning.
- By afternoon, it is drier with chilly temperatures but well above freezing in the upper 40s. So, while not a long duration event, it is still something to monitor Saturday Night and Sunday Morning.
HOW MUCH SNOW?
- This will vary and WILL change. Preliminary suggestions are 1-2" of slushy snow in the valleys around Chattanooga to Cleveland with more possible and in the mountains.
- Higher amounts north of Chattanooga/closer to I-40 and mountains east of I-75
- None to 1+" in North GA/AL with isolated higher amounts in the mountains.
- This WILL fluctuate. Could be more rain, could be more snow. Over all this system is quick.
- As always, things can change and we will keep you updated on this in the days ahead! Temperatures look to stay below average for this time of year through next week with a few more rounds of colder air moving in!
WILL WE HAVE SCHOOL MONDAY?
Most of the snow, if any, will melt on Sunday. Temps will dip close to or below freezing on Monday morning. Overall we don't expect a major travel impact, but I could see some delays in northern parts of the viewing area in the least.
