A series of weather systems will bring three rounds of snow to the area this weekend. The first arrives this evening. Snow is ongoing over our far southern counties this evening. This snow will try to creep northward toward the I-90 corridor, but whether it can actually make into the immediate La Crosse area is still in question. Areas north of I-90 look to see little more than flurries, if that. Snow will end late tonight. As far as accumulations are concerned, look for the heaviest snow to fall across parts of Allamakee, Winneshiek, Crawford, Richland, southern Junuea and Adams Counties. Snow totals in these areas will range from 2 to as many as 4 inches. Farther north, toward La Crosse, amounts will quickly drop off to a dusting. No accumulation is expected north of I-90. Look for lows tonight to range from the upper single digits in the north to the middle and upper teens from I-90 and points south. Look for a breezy night as north winds blow between 10 and 20 mph. This could cause some blowing and drifting of snow across the south.

As we head into tomorrow, look for a break during the first half of the day. By afternoon, another ripple of energy will move northeast across Iowa and Illinois. It will bring another round of snow to the region for the afternoon into Saturday night. Just like tonight, the area most likely to see accumulations will lie across our far southern and eastern counties. Another 2 to 3 inches of snow are possible in these areas. Farther north, toward La Crosse, look for a chance of light snow, however, accumulations look to remain under one inch. There is still some question as to how far north this area of snow will get. In fact, some of the early evening model data suggests that the bulk of the accumulating snow may stay just south of the our area. Be sure to check the latest forecasts as snow amounts may have to be adjusted depending on the track of the system. Look for highs in the upper teens to lower 20s in the north and lower to middle 20s in the south.

A WINTER WEATHER ADVISORY  has been issued for Winneshiek, Allamakee, Crawford, Richland, Juneau and Adams Counties through Saturday night. These areas could see anywhere from 4 to 7 inches of snow through Saturday night. Those of you with travel plans over the southern third of Wisconsin should prepare for snow covered roads and slick travel. As mentioned above, these amounts may need to be lowered depending on the track of tomorrow’s system. In La Crosse and the I-90 corridor, snow amounts will range from a trace to around an inch through Saturday night but may need to be adjusted downward, depending on the track of tomorrow’s system. Areas north of I-90 will not see more than a dusting through Saturday night.

As we head into Sunday, look for a quiet start to the day into Sunday night. Another upper air disturbance will track into the region late in the day and bring yet a third round of light snow. This time, it appears much of the region could see some light accumulations. Look for highs on Sunday in the upper teens to near 30F in the south.

Looking ahead… We are in for a fairly active period next week as a series of weak to moderate weather systems move through the region. Each will bring a round of light snow with some accumulation possible. Timing these systems out is tricky, but it appears teh best days for seeing snow are Tuesday, Wednesday and Friday. Temperatures look to be all over the place, with highs in the 20s this weekend. They will warm into the 30s Monday and Tuesday, then crash into the teens and lower 20s from Thursday through next Saturday. Overnight lows will fall for the 20s into the single digits and tens for the last half of the week. All in all, it is possible many areas may actually see several inches of snow on the ground by the ed of next week. Stay tuned!
