Another Messy Storm System Approaches

A system approaches for Sunday and Monday, bringing a messy commute to the area.

All eyes are on the next storm system which will approach our region Sunday. Before I dive into that mess, here is a quick look at the warm-up we are expecting as we approach the weekend....

Friday GFS

Above is the 850 mb temperature and wind forecast for Friday.  I would like to point out the relatively strong temperature/pressure gradient we are seeing that day. This can be seen with the stripes of colors over our region... going through 3 shades of blue in the state of Ohio. This strong temperature gradient will likely bring gusty winds to Ohio on this day.

SAT GFS

Progressing into Saturday, the above image shows a southwesterly flow developing. As a result, warm air will advect into our region, with the green shading indicating a temperature of 8 degrees celsius at the 850 mb level (mid 50's at surface). Something to look forward to!

Meanwhile on Saturday, we will see the next rain system developing to our southwest. By 1 AM on Sunday morning, the GFS expects the system to move northeastward and start bringing rainfall to our region.  (Refer to picture below) 

The GFS model expects the rain to continue throughout the day on Sunday, before exiting the region around 4 PM Sunday evening. (Refer to picture below).

It will remain warm enough throughout the duration of the storm for the precipitation to fall as rain. However, a strong rush of cold air will enter the region Sunday night with a developing northwesterly flow. (Refer to picture below). 

A seperate band of moisture will push into the region from the northwest for early Monday morning. With cold air already in place, this moisture will likely fall as snow. The GFS model expects snowfall to start around 7 AM Monday. (Refer to picture below) 

Road conditions will be slick for Monday morning. In addition, the remainder of next week will be influenced by cold arctic air, and we will likely see more snow showers into the new year!
