Real-time Bowling Green weather radar:
Today 2/23 – Partly Cloudy; Cold – High 22º / Tonight – Partly Cloudy; Cold – Low 12º
6am 22°– 9am 19˚ – 12pm 20˚ – 3pm 22˚ – 6pm 20˚
Good morning, south central Kentucky! Be sure to watch for black ice on your morning commute, as temps will be hovering around 20º today. Mostly cloudy skies throughout the morning is expected to give way to filtered rays of sun by this afternoon.
This will be thanks to an area of high pressure that settles over the Ohio Valley this evening. The surface map below is valid for 6pm, and depicts the high over southern Illinois/Indiana:
This area of high pressure will usher cold air into the region today, and we may actually cool a few degrees this morning, before reaching the lower 20s again this afternoon. Northerly winds are expected to pester us at around 10 mph through mid-morning, meaning wind chill values could drop around 0-10ºF. Layer up, folks…
Fortunately, wind chills will rise as winds die down this afternoon. We can expect a cold night under the influence of calm winds and partly skies. Low temperatures will drop to the lower teens. Some rural locations could see single digit readings.
Tuesday 2/24 – Partly Cloudy – High 33º / Tuesday Night – Mostly Cloudy – Low 22º
The cause of this persistent cold is what we call a trough in the jet stream. This trough is currently positioned over the eastern U.S. with a ridge over the west. A few disturbances will rotate through the trough this week, meaning persistent shots of cold air will keep temperatures below normal across all of south central Kentucky.
Temperatures will warm to the lower 30s Tuesday afternoon under partly cloudy skies. This will be a good afternoon for much of the remaining snowpack to melt. A cold front is anticipated to move through the area Tuesday night. Although isolated snow showers will stay to our north, cold air will move in behind the front, with lows dropping into the lower 20s.
Wednesday 2/25 – Partly Cloudy – High 37º / Wednesday Night – Scat’d Flurries – Low 15º
Expect Wednesday’s weather conditions to look very similar to Tuesday’s, with the exception of us getting a few degrees warmer. Another disturbance will move through the trough in the jet stream Wednesday evening bringing….you guessed it, another shot of cold air.
There could be enough lift along Wednesday night’s cold front to bring some flurries to southern Kentucky, but as for now just expect another cold night with temperatures in the middle teens.
The rest of the week looks cold, but it appears likely that we’ll stay dry enough for the sun to melt most of the snowpack left across the Commonwealth.
That’s all I’ve got for this morning. Be sure to check out @WxOrNotBG and @WarrenCountyWX on Twitter for real-time weather updates.
