Friday evening update...

A little break from the cold wetaher this weekend... And we need it !! Officially 20.1 inches of snow in Louisville for the winter and yes sir... that is above average. This go around however, it looks like it'll be all rain.

We do have a weak system passing through overnight. The low layers are super dry though so only very light precip expected - with the best chances to the north of the metro. Low level temps suggest that there could be a quick bout of light frzg rain / sprinkles in these areas.

Clouds are expected to thim some for Saturday afternoon allowing for temperatures to climb into the upper 40s making for a decent afternoon. Later Saturday night into Sunday, a few WAA showers may skirt the area with the best chances just north of the Ohio River. By midday into the afternoon, we are expecting mainly dry conditions with a few breaks in the clouds possible. Temperatures in the boundary layer suggest low to perhaps mid 50s by later Sunday afternoon. The main storm will push in for Sunday night and early Monday with rain but also continued mild temperatures.

Much colder air will shift back into the region for next week as temperatures once again settle to levels way below average with also the increased chance for snow showers by Tuesday night or Wednesday as much of the data is closing off a strong surge of H5 energy in the Ohio valley.

These colder than average temperatures look as if they will hold firm into next weekend as well. So let's talk big snow ??? chances ??? not great at this time. If (and only if) we get phasing occurring between the northern and southern streams just to our west then will we see those bigger snow chances increasing for our area. At this time though... I don't see it happening - which by the way won't disappoint me all that much as it's time to bring on Spring and thunderstorms !!

have a great weekend all

Jay
