Cold Temperatures Expected to Continue

Real Time Bowling Green Weather Radar:

Today 11/13 – Decreasing Clouds; Cold – High 37º / Tonight – Partly Cloudy; Cold – Low 20º

6am 29º – 9am 31º – 12pm 34º – 3pm 37º – 6pm 32º

Good morning, we are off to another cold start in southern Kentucky as current temperatures are in the upper 20s. Cold air advection in the low levels has actually helped to trigger some snow showers just to our south. It’s possible that we could see a snow flurry or two over the next few hours, but no accumulation is expected.

The pesky cloud cover that stuck around yesterday is still hanging around thanks to the influence of the upper- level trough centered over the U.S. The good news is that surface high pressure will move over Kentucky later today and help to push these clouds out. Expect skies to become partly cloudy this afternoon with high temperatures only reaching the upper 30s.

It looks like we have a good chance of seeing some of the coldest temperatures of the season so far tonight as lows are expected to tumble to near 20º. It would not be surprising to see a few rural locations drop into the teens overnight.

Fri – Mostly Sunny; Unseasonably Cold – High 36º / Fri Night – Mostly Clear; Cold – Low 19º

Not much change to the forecast is expected tomorrow as surface high pressure will move east over the Missouri Valley.

Sat – Partly Cloudy – High 42º / Fri Night – Mostly Cloudy; Iso’d Rain & Snow Showers – Low 32º

We will see a few changes in the forecast on Saturday as the jet stream becomes zonal Saturday. This will allow for some weak warm air advection that will help our high temperatures reach the 40s. Another disturbance looks to rotate through the upper-level trough Saturday night and spread some precipitation through the Ohio Valley.

At this time it looks like most of the forcing will stay north of the Ohio River. We still can’t rule out an isolated rain or snow shower Saturday night, but it looks like most of the precipitation will stay north of southern Kentucky. No snow accumulations are expected at this time.

The forecast certainly becomes more interesting on Sunday and Monday as an area of surface low pressure will attempt to make its way up the Appalachian Mountains. The potential for snow to fall somewhere in Kentucky is present with this system. Models will likely waffle back and forth with the position of this low over the next few days. If the low moves east of the Appalachian Mountains, most of the moisture will be off to our east. If the low moves west of the Appalachian Mountains, the air will be too warm for much snowfall. If the low tracks right along the mountains, this is historically a sweet spot for snow-producing systems in Kentucky. We will be keeping a close eye on this system.

That’s all I’ve got for this morning. For real-time weather updates be sure to check out @WxOrNotBG and @WarrenCountyWX on Twitter.
