AREA...Eastern Oklahoma and Northwest Arkansas. ONSET...After 9 pm. DISCUSSION... A band of snow that developed across northeastern Oklahoma and northwestern Arkansas this morning continues to dissipate this evening. Little to no additional accumulation is expected from this activity. Another area of precipitation is developing across northern Texas and this precipitation will spread across portions of southeastern Oklahoma this evening and early tonight. As arctic air spreads toward the Red River this evening, any precipitation that forms across southeastern Oklahoma will likely fairly quickly turn to snow. Any accumulation from this activity will be light. Temperatures falling into the single digits and lower teens overnight combined with north wind of 10 to 20 mph will result in dangerously cold wind chill values from minus 5 degrees to minus 15 degrees. Frostbite of exposed skin is possible in these conditions in less than 30 minutes. SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...

Dangerously cold wind chill will persist into Tuesday afternoon across much of the region as temperatures recover only into the teens to around 20 degrees with a northerly wind continuing. The arctic system settles over the region Wednesday morning resulting in very cold temperatures but the wind will weaken. The coldest temperatures will be over snow-covered ground in far northeastern Oklahoma and far northwestern Arkansas. A strong storm system is expected to develop into the Southern Rockies late this week. Southerly low level flow will return to our region ahead of this system, allowing for a warming trend to begin Thursday and continue through the weekend. The main system will move through the Southern Plains late this weekend, resulting in showers and isolated thunderstorms across the area Saturday night and Sunday. contains additional information.
