...Freeze watch remains in effect from late tonight through Saturday morning... ...Freeze watch remains in effect from Saturday evening through Sunday morning...

* temperatures...readings will fall to around the freezing mark Saturday morning. Colder readings are expected Sunday morning as The Heart of a much colder airmass moves across the Ohio Valley. Expect temperatures to drop into the 20s for many locations.

* Timing...breezy conditions Friday night will keep readings from falling too fast. Freezing temperatures should begin a few hours before daybreak and continue past sunrise. Calmer conditions Saturday night will mean a quicker drop in temperatures...with some locations reaching the freezing mark late Saturday evening.

* Impacts...the freezing temperatures this weekend should bring an effective end to the growing season. In addition... scattered snow showers are forecast early Saturday morning east of the I-65 corridor. A brief accumulation is possible in areas where the snow rate is highest. Road temperatures will be too warm for accumulations...however moderate snow will reduce visibilities in some spots making driving hazardous.

Precautionary/preparedness actions...

A freeze watch means sub-freezing temperatures are possible. These conditions could kill crops and other sensitive vegetation.

Special Statement
Statement as of 3:11 AM CDT on October 31, 2014

...First snow of the winter season expected for much of the area tonight and early Saturday morning.

Overview...

A very strong weather disturbance will drop southward out of Canada and down through the Ohio Valley later today and tonight. This feature will bring widespread rain showers and windy conditions to the area. Northwest winds of 15 to 20 mph with gusts of 30 to 35 mph will be possible this afternoon and tonight. Much colder air will filter into the region tonight resulting in the rain showers changing over to snow showers before diminishing late tonight.

Snow potential...

As colder air pours into the region tonight...surface temperatures are expected to drop from the upper 30s down into the lower 30s by Saturday morning. Rain showers will change over to snow showers during the evening hours. Some bands of moderate snow may develop over portions of east-central Kentucky. While this snow will be fighting relatively warm ground temperatures...a inch or less of slushy snow on grass and elevated surfaces will be possible in areas east of a line from Frankfort to Albany Kentucky. In areas out toward I-65 and points west...little if any snow accumulation is expected.

Cold temperatures...

Temperatures late tonight and early Saturday morning are expected to drop to near freezing. However...even colder conditions are expected Saturday night and Sunday morning as temperatures are expected to drop into the mid to upper 20s. If temperatures drop this low...this will result in a killing freeze and bring an end to the growing season. At this time...freeze watches are in effect for tonight and again on Saturday night.

Societal impacts...

With temperatures falling into the 30s tonight and winds gusting into the 25 to 30 mph range...wind chill readings will make it feel like it is in the lower 20s this evening. While light snow is expected to fall tonight...surface temperatures are expected to remain above freezing. This will result in area roadways remaining simply wet. It is possible that a few icy spots may develop on area bridges and overpasses toward sunrise on Saturday as temperatures approach 32 degrees.
