Saturday Weather Briefing: Showers developing today, will increase in coverage throughout the weekend

The next 24 to 48 hours is going to feature a lot of clouds and periods of rainfall across the Western Carolinas.  As you wake up this Saturday morning you’ll notice an increase of clouds across the area, this is just the precursor to a wet weekend across the region.

 

Looking at synoptic scale features we have a few things working for us. First off, high pressure is located off the East Coast of the US and that is allowing a return flow from the southwest not only near the surface but aloft as well. This is allowing a solid transport of moisture into the Southeast US. We also have a broad trough that by tonight will sharpen up a tad back across the Mississippi River Valley region.

 That also provides jet energy to help develop shower activity. A weak surface low will also be in the Gulf of Mexico through Sunday bringing an additional focus of shower activity.


 

As you can see on the latest model data, light amounts of moisture will begin to impact the region by the afternoon hours, spotty light rain showers are possible. Then as we get into the evening hours moisture will begin to increase in coverage across the entire Southeast thanks to the sharpening jet. That will result in an increase in shower coverage for tonight.

Widespread rain showers are expected for the start of your Sunday and should continue for a good part of the day peaking in the afternoon hours before finally tailing off by Sunday evening.

Rainfall amounts through Sunday continue to look modest with the lightest totals being in the ¼ inch rain while some spots of exceed ½ inch of rain and could approach ¾ of an inch.

Moisture will move out as the trough begins to pass through ushering colder air into the region to begin the new work week. Then what should we expect weather-wise heading into the first days of February? We’ll have that in an update later today.
