A Brief Warm-Up After the Rain

The rain and overcast skies finally cleared the Bowling Green area around noon today. The cold front responsible for these conditions was nearly stationary as it passed over us last night, but it briefly surged ahead this afternoon, only to stall over the Appalachians. Fortunately, this front is no longer a bother to us, and we will see continued clearing as the evening goes on. High pressure will slide in from the southwest as a response to this retreating frontal system. With plenty of low-level moisture in place thanks to the rain, this high will keep the moisture pinned to the ground. As a result, fog is expected, dense at times, tonight into early tomorrow morning. Use caution if you are driving during these hours.

Skies tomorrow should be virtually cloud-free as the ridge of high pressure parks itself over eastern Kentucky. This ridge may drift northward enough to allow warmth from the Gulf states to creep our way. Consequently, high temperatures tomorrow will have a shot at cracking 70°. This "warmth" will not stick around, though, as a weak cold front is expected to move through south-central Kentucky early Saturday morning. Temperatures will dip slightly, and a few showers will be possible, although the models indicate that the best chance for rain will be along and north of the Ohio River. Cloud coverage will increase as well, although the sun should return in time for Sunday.
Temperatures valid at 4 PM on Friday as modeled by the NAM

Friday: High of 68°. Dense fog is likely in the early morning hours, and may last until 9 AM. Abundant sunshine, though clouds will increase late Friday night. Winds from the southwest at 5 mph.
Saturday: Morning low of 46°. A 30% chance of rain before noon; no significant rain accumulation is expected. Mostly cloudy skies with a high of 61°. West winds at 5-10 mph.
Sunday: Morning low of 39°. Sunshine returns with a southwest wind at 5-10 mph. High near 65°.
