Rain Chances are on the Increase Heading Into this Weekend!

Throughout the rest of this evening and heading into tomorrow morning, slightly warmer temperatures will advect into the Ohio River Valley, thanks to light winds out of the south. Overnight temperatures around the area are going to be a lot warmer than they have been over the past few nights. Temperatures will hover around the 50° mark throughout the night and into tomorrow morning. Rain chances are on the increase heading into the overnight hours as a weak shortwave disturbance propagates just to our north. This disturbance will tap into some of the moisture located in the lower levels of the atmosphere and spark off some shower activity. QPF (Quantitative Precipitation Forecast) will remain fairly light, with rainfall totals by daybreak right around a tenth of an inch.

Heading into your Friday, extensive cloud cover will limit the temperatures from rising too much throughout the day, but temperatures will still remain well above average. The high temperature on Friday will hover right around the 60° mark. Shower chances will remain on the higher side for Friday night, as a boundary will hover around the Ohio and Tennessee River Valleys, triggering some showers around the area. Models are in agreement, indicating that a half to three-quarters of an inch of rain could fall by Saturday morning. The LLJ (Low-Level Jet) will crank up out of the southwest as a surface warm front moves north through our area. Low temperatures for Friday night, heading into Saturday morning will remain in the mid-50s.

Any shower activity lingering around the will move on out of the area by the mid-to-late morning on Saturday. Slightly drier air will try to nose into the region, breaking up some of the cloud cover, areas west of the I-65 corridor could experience some sunshine during the early afternoon hours. As of right now, the area still has a shot of seeing some strong thunderstorms during the afternoon and evening hours on Saturday. The Storm Prediction Center has the Bowling Green area under a marginal risk (1 out of 5 on the Categorial Outlook Legend) for severe weather.
