Updated Tuesday evening:
The predictions remain for icy weather, but the worst of the impact will be further to the east of Clinton than what was predicted this morning, more toward Heber Springs. Ice remains forecast for throughout Northern Arkansas with storms to the south.
Forecast as received Tuesday evening (emphasis added):
A storm system moving through the region will bring a chance of stronger storms to southern Arkansas and winter weather to the north. The area of most concern for icing is northeast Arkansas where an ice storm warning is in effect.
Isolated strong storms will be possible through the night over the southern and southeast third of the state. The primary concern with any stronger storms will be hailstones greater than an inch in diameter.
Of greater concern is the wintry precipitation. Freezing rain and possibly some sleet is expected over roughly the northern half of the state with amounts generally a tenth of an inch or less.
The heaviest amounts of ice are expected from Mountain View to Heber Springs northeast to Pocahontas and Walnut Ridge. In these areas a quarter of an inch or more of ice can not be ruled out and as such, an ice storm warning in in effect. This amount of ice is sufficient to bring down trees and power lines.
The heaviest ice and freezing rain accumulations are expected between 6 p.m. to Midnight. The freezing rain / ice will end from northwest to southeast after midnight. The primary impact from the icing is expected to be slick roads and hazardous travel conditions, especially over the northeast parts of the state. Temperatures on Wednesday will warm enough that road conditions are expected to improve.
- end update -
The National Weather Service North Little Rock office is forecasting hazardous weather beginning Tuesday afternoon into Wednesday morning, with possible sleet and freezing rain, centered in Clinton and to the west, into Cleburne County.
The forecast (emphasis added):
A winter weather advisory has been issued for much of northern and parts of north center Arkansas. Winter weather will affect Arkansas Tuesday evening through Wednesday morning. Weather factors are coming together and indicating an increasing chance that winter weather will affect the area, including measurable freezing rain and sleet.
A weather system will move through the area, and a cold air mass will filter into Arkansas, and freezing rain and sleet will develop. It will cause hazardous weather and driving conditions. A few hundreds to around a tenth or two of freezing rain and sleet may fall by the time the system pushes east of Arkansas on Wednesday. There is some potential if factors come together that isolated areas may receive more freezing rain amounts. Also ahead of the cold, scattered shows and thunderstorms will develop, with some stronger to severe storms that may produce hail around one inch. A marginal risk of severe storms has been issued by the Storm Prediction Center of much of central and southern Arkansas for this afternoon to evening to the early overnight.
Otherwise, another weather system will affect Arkansas this coming weekend and bring rain, and again some potential for winter weather. Uncertainty does exist in the forecast for winter precipitation and it is dependent on the amount of moisture remaining on the back side of the system and how quickly the cold air filters into Arkansas.
Please refer to the latest forecasts, advisories and possible warnings during this weather event.
We will make every effort to update this forecast as new information becomes available.
