Its a Wash, Rinse, Repeat Weather Pattern: rain, clouds and bouts of cold...

Good Wednesday to everyone…an unsettled weather pattern continues today across the Western Carolinas.

 

Cold air damming settled in overnight and is firmly in place across the region here at the late morning hours. Temperatures after being in the upper 50’s and lower 60’s just 24 hours ago are a solid 15+ degrees colder.

For the rest of today clouds, mist and drizzle will continue as warm air is overriding this cold pool. Expect little change in temperatures the rest of the day, everyone should remain in the 40’s.

 

Another in a long line of disturbances in the jet stream will traverse the southland late tonight and early Thursday morning. This will help continue the overrunning process overhead and models are responding by having another round of light showers move through overnight…amounts shouldn’t be heavy but it will work to help sustain the CAD. As a result Thursday will likely remain cloudy for most areas slowly moderating temperatures.

We then shift our attention to the next frontal boundary that will approach on Friday and deliver a shot of winter-like cold to the region…thanks in part to a massive surface high that will slide across the Great Lakes Region and into the Northeast…

 

Friday will feature partly cloudy skies and high’s in the 50’s but by first thing Saturday morning a 1037 mb surface high will be located over Southern Ontario with the cold air funneling southward. Temperatures will really tank by Saturday morning bottoming out in the upper 20’s for everyone bringing a hard freeze to the region.
