Thursday, January 12, 2012 - 11:57 am

The National Weather Service has issued an ice storm warning for the St. Lawrence Valley, through 7 p.m.

Icy conditions that are making driving and walking difficult are expected to continue, as rain falls and freezes immediately on roads, sidewalks, and car and truck windows.

The NWS warning says another half an inch of ice could build up.

As of 11:30 a.m., none of National Grid's 42,787 electric customers in St. Lawrence County had reported they were without power, but that could change if ice continues to build up on power lines.

If you’re traveling to the west, keep in mind that an ice storm warning has been issued for Jefferson County, and more ice accumulations are expected there.

Between now and when clear skies are predicted to return Sunday night, the National Weather Service continues to warn of combinations of snow, sleet and freezing rain across the St. Lawrence Valley and northwestern Adirondacks.

Temperatures today will top out at about 30 degrees with continuing snow and rain. Accumulations of snow and sleet today won't be more than an inch or two, but the ice could continue to form and build up.

Freezing drizzle, sleet and freezing rain are expected to continue tonight, tapering off a bit. The temperature won't drop below the mid-20s tonight. Additional sleet accumulations might amount to about half an inch, according to the NWS.

Friday, the chance of precipitation rises again to 90 percent, as more rain, sleet and snow are expected. Highs could reach the mid-30s.

The temperature will drop to the single digits Friday night, and a some light snow accumulation might be seen. Moderate winds with possible gusts up to 25 mph could send wind chill values into the minus-teens.

It will stay cold Saturday, with highs of 5 to 10 degrees under cloudy skies. Saturday night and Sunday, skies begin to clear, with lows at night between 10 and 15 below and highs Sunday around 10 above. Sunday night it will be clear again, with lows 0 to minus 10.
