(WKOW) -- A winter storm watch has been issued for southern Wisconsin.
A potent winter storm is expected to dump well over half a foot across much of the area. Winds may also gust over 45 mph making driving nearly impossible Saturday night.
The watch is in effect through late Saturday night.
The daylight hours of Friday will be quiet with increasing clouds and cooler system on the back side of our first cold front dropping temps to the mid 30s.
A stronger storm system moves in from the Central Plains and by Friday night, snow will develop, especially farther south and east.
Accumulations Friday night have come up a bit and look like 2-5 inches will fall through Saturday morning.
The elongated low pressure will continue to impact our region on Saturday too, with snow redeveloping from SE to NW, especially by the afternoon and evening.
Snow wraps up Saturday night. There is a high chance of at least 4" of accumulating snow SE of Madison. Expect a sharp cut off with the snow NW of Dane County.
Final Totals will range from 4-8 inches west (this is the area with the highest uncertainty) And 8-12 inches for most of Central and SE Wisconsin.
The end of the weekend will be colder with temps in the low 20s and partly sunny skies. Another shot at a little light snow by Sunday night and early Monday.
