Good Wednesday to everyone, we’re at the mid-point of the week and today’s weather is pretty much summed in one word………..wet!
A strong upper level disturbance, surface low and warm front will combine to deliver a healthy rainfall to Western North Carolina today. As you can see on the water vapor image posted the upper low situated across the Southern Plains will charge eastward today helping to bring deep moisture up into the Southeast. A surface low will run from the Mississippi River in Northern Mississippi to across the Northern sections of Georgia and into Upstate South Carolina by late in the day.
The moisture overrunning north of the surface low track will yield a steady moderate to at times heavy rain while further south into South Carolina and Georgia a few thunderstorms are even possible.
Rainfall has moved in overnight and it should become steady by around daybreak and will remain that way through the lunch hour. That is where our region will see the heaviest rainfall totals.
Then as the surface low moves to our south, the rainfall will begin to transition into a more scattered nature but will last through the afternoon and into the evening hours tonight before ending.
Rainfall totals continue to look quite healthy for today, amounts will be in the 1 – 1.5 inch range, a few localized spots could exceed those numbers as well. Best chances of that might be in our southern tier or along the Blue Ridge.
Temperatures for today are not going to move a whole lot, stuck in the 50’s which is going to be a shock to the system compared to the warm temperatures of yesterday.
Our rain event will slide out tonight and some clearing might occur in the evening hours resulting in a cooldown. Low’s tonight will drop into the upper 30’s. Some fog may also try to form as well toward Thursday morning.
Speaking of Thursday, we are going to be looking at cooler weather. A surface high located across Pennsylvania will funnel a cooler airmass into North Carolina, at least temporarily on northeast winds. The jury is still out on exactly how much sun we see on Thursday. Some guidance is trending to keep the clouds in for a good part of the day, keeping high’s in the 40’s However if we see a bit more sun, a few low 50’s might pop up.
The cool down will only be temporary as high pressure slides off the coast on Friday, that brings milder weather for the end of the work-week and the first half of the weekend. It will also result in increased rain chances as an arctic front will approach the region.
Coming up later today on our briefing page, we’ll have a detailed update on the Christmas holiday forecast and take a look at the weather pattern that might be materializing for the timeframe after Christmas…stay tuned!
