Weather Alert in Kentucky
Special Weather Statement issued February 22 at 10:39PM EST by NWS Jackson KY
AREAS AFFECTED: Fleming; Montgomery; Bath; Rowan; Estill; Powell; Menifee; Rockcastle; Jackson; Pulaski; Laurel; Wayne; McCreary; Whitley; Knox; Elliott; Morgan; Johnson; Wolfe; Magoffin; Lee; Breathitt; Owsley; Clay
DESCRIPTION: Some light snow accumulations are expected through Monday as rounds of snow showers track across the area. Wind gusts as high as 20 to 30 mph could occur in the heavier snow showers. This, when combined with the falling snow, could produce sudden sharp visibility reductions and quick light snow accumulations, especially on Monday afternoon. Event total snow accumulations between a dusting and around 1 inch are expected, with locally higher amounts possible where snow showers are the most persistent overnight into Monday. Temperatures tonight will be in the low to mid 20s, so expect times of slick, slushy, or snow covered roads. Any untreated roads and surfaces, including bridges and overpasses may be icy in some locations. If traveling tonight or on Monday, slow down and exercise caution. Allow plenty of extra time to reach your destination.

Precipitation in the form of water droplets is called rain.
Rain generally has a tendency to fall with less intensity over a greater period
of time, and when rainfall is more severe it is usually less sustained.
Rain is the most common form of precipitation and happens with greater frequency
depending on the season and regional influences. Cities have been shown to have
an observable effect on rainfall, due to an effect called the urban heat island.
Compared to upwind, monthly rainfall between twenty and forty miles downwind of
cities is 30% greater.

Weather Topic: What is Sleet?
Home - Education - Precipitation - Sleet
Next Topic: Snow
Sleet is a form of precipitation in which small ice pellets are the primary
components. These ice pellets are smaller and more translucent than hailstones,
and harder than graupel. Sleet is caused by specific atmospheric conditions and
therefore typically doesn't last for extended periods of time.
The condition which leads to sleet formation requires a warmer body of air to be
wedged in between two sub-freezing bodies of air. When snow falls through a warmer
layer of air it melts, and as it falls through the next sub-freezing body of air
it freezes again, forming ice pellets known as sleet. In some cases, water
droplets don't have time to freeze before reaching the surface and the result is
freezing rain.
