Rainy Sunday, Warm Next Week, Watching Winter Weather

Temperatures dropped to around 29° last night. However, southerly surface flow should help warm temperatures to around 53° by this afternoon. The southerly wind will be around 10 to 15 mph, but with gusts up to 25 mph possible.

Moisture will also begin to spread into the region. This could lead to the development of showers by 3 AM. Overnight lows will drop to around 36°. Nothing better than a cold rain!

Soggy Sunday

A soggy Sunday is in the forecast. Southerly flow will pump moisture into the region leading to widespread showers throughout the day on Sunday. This will also limit highs to around 50°. The Hi-Res NAM Model says Bowling Green could receive up to a quarter inch of rain.

The rain should exit the region by late Sunday afternoon and into the evening hours. Mostly cloudy skies will stick around as lows drop to around 40°.

Early Week Warmth

The warmth really looks to return early next week! A deep trough is expected to develop over the southwestern United States. This sets the stage for prolonged southwest flow. As a result, temperatures on Monday will top out in the mid 50s despite mostly cloudy skies.

Looking Ahead

It is beginning to look like there is good potential for the development of a winter storm around Christmas Eve. The question is where does the precipitation set up. As expected, models are constantly changing the location of the precipitation axis. As seen below, the GFS Model puts the precipitation axis right across the region. However, the European Model suppresses precipitation well to the south of the region.

All in all, we’ll just have to continue watching the models until they have a better grasp on the system. However, treat this as an early “heads up”, there could be a few travel hiccups come Christmas Eve and Christmas Day.
