All Sleet, Sleet, Sleet

All sleet, sleet, sleet…OH YEAH!!

This Afternoon – Wintry Mix – High 40˚ / Tonight – Scat’d Showers – Low 34˚

3pm 40˚ ~ 6pm 36˚ ~ 9pm 37˚ ~ 12am 36˚ ~ 3am 35˚ ~ 6am 38˚

We are currently lodged between two surface boundaries.  A stationary front is located to our south, with a warm front lifting north of the viewing area.  This can be viewed on the surface model below, which displays current frontal positions and radar reflectivity:

Surface Model Valid 3pm 1/9/13

These forcing mechanisms (stationary & warm front) have coincided with available moisture and temperature profiles to create a mixed bag of wintry precipitation across south central Kentucky.

As I mentioned was possible in this morning’s forecast post, sleet/snow has gathered on grassy surfaces.  Temperatures are still well above freezing, so any traveling concerns should stay minor at best.  We’re already seeing sleet taper off, with a gradual transition to scattered rain showers taking place across south central Kentucky.  This should lend a helping hand for the evening commute.  Curious as to what’s occurring in our atmosphere to create the sleet/snow/rain mix?  Take a look at the following graphic for a better understanding:

Fri – Iso’d Showers – High 55˚ / Fri Night – Rain Likely – Low 48˚

A cold front will approach our area from the northwest, which will amp up moisture values across our proximity.  Isolated showers will gradually increase in coverage as we progress throughout our Friday as a result.  As the front advances west to east across the area Friday night into Saturday, widespread rain showers, along with a few storms are expected.  Nothing severe is on the table, however, moderate to heavy rains will be possible.

Sat – Rain Early – High 53˚ / Sat Night – Cloudy – Low 31˚

We’ll kick off our Saturday with widespread rain showers.  I fully expect activity to taper off as we get into the afternoon and evening, as the front advances east of the area.  The NAM simulated radar model below is valid for 3am Saturday morning.  As you can see, this particular run likes the idea of damp conditions at this time:

Clouds should break up throughout Saturday night, with rays of sunshine slated to return on Sunday, as high pressure takes over.  High temperature values are expected to remain in the lower 50s throughout the entire weekend.

That will wrap up the afternoon forecast post, folks.  Don’t forget to stay in touch with me @Wx_Or_Not for more frequent information.  Have a great day, stay safe, and thanks for reading.
