Short-term models are predicting a significant outbreak of snow showers/flurries this afternoon and evening.  With temperatures in the 20’s, snow will accumulate and slick roads will develop.  With the cold air around, the light, fluffy snow could accumulate to several inches this evening.  Water content will be very low, but dry snow accumulation features plenty of air to fluff it up.  The low water content, however, should allow roads to stay  in fairly good shape.

Snow should begin in Louisville area by mid afternoon.  Accumulating snow will end before midnight.  The whole area should get about an inch of snow. However, systems like this usually form some heavier “cells” of snow showers.  If one of these hits you, 2″-4″ inches will be likely.

So as an estimate:  within a 40 mile radius of Louisville…                                                                        up to 1″ – near 100%                                                                                                                                        1″-2″ –   about 50% of the area                                                                                                                      2″-4″ –  about 20%                                                                                                                                            4″+   – about 5%

Since yesterday, I found the traditional greeting for the season

Lo Saturnalia   (lo is pronounced    “yo”)

Saturnalia is the reason Christmas is celebrated on Dec. 25th
