Tonight: Lingering light rain will with us until around midnight and then all of the moisture will quickly move east. Our sky will be mostly cloudy through Tuesday morning. Lows will fall into the 40s with some upper 30s in the mountains.
Jackets on Tuesday: As the cold front passes, our winds will switch to the north-northwest. These north winds will pull in colder air and you will be able to notice the change tomorrow. Along with the cool breeze, a mostly cloudy sky will keep temperatures from warming much. Highs will only reach the 50s in Upstate towns with some 40s for Western NC towns.
Chilly Wednesday: Another weak low pressure system will cruise closer to us Wednesday narrowly missing to the south. Rain will likely fall south and east of us down toward Columbia and Charleston, but we will be close enough to this system to stay cloudy most of the day with a few rays of sun possible. Meanwhile, Western NC will have a mixture of sun and clouds. Also, a wedge of cool air funneling down from the northeast will keep temperatures cool on Wednesday. Highs will only make into the upper 40s and low-middle 50s area-wide.
Thursday Sun: The sunshine will return Thursday and so will comfortable conditions by afternoon. We'll start the day chilly, but highs will reach the upper 50s for the Upstate by mid-afternoon.
Update: Intense Storm Possible Next Week: There's no real way to tell specifically what sort of storm we will be dealing with by early next week and more importantly how that storm will affect our region. But, odds are in favor of an intense storm system affecting parts of the southeast Monday, Tuesday or Wednesday of next week.
There are a couple of different forces battling it out right now in a northern hemispheric game of tug-of-war [(1)a fast pacific flow and (2) the Canadian cold)]. The battle between these two flows is making for erratic swings in what's being projected on forecast models. Nevertheless, it looks as if an intense storm will be part of a trigger mechanism inviting a pattern change to colder air which is set to occur toward the 17th or 18th of December. Keep in mind that this pattern change won't be sustained cold for weeks, but it will be colder air than we have seen in a while and potentially periods of colder air with a suppressed storm track opening up the possibility for southern storm systems.
I'm betting we will deal with a system early next week that brings rain and t-storms to our area which will then be followed by some colder air. Of course, there's still a lot of time to evaluate what sort of weather conditions we will experience.
