UPDATE: More Winter Weather Expected Overnight

Following a large swath of winter weather Wednesday morning, we are expecting more to impact much of northern and central Oklahoma overnight Wednesday into Thursday morning. Some areas may see heavy snow while others see freezing rain or a wintry mix. We'll outline what you can expect from this system by region.

NORTHWEST OKLAHOMA (including the panhandle) will see snow beginning later Wednesday night and lasting until around noon Thursday. Snowfall rates may be heavy at times, leading to significant accumulations. Between 4 and 8 inches of snow may accumulate across this region overnight. Strong southeasterly winds blowing at 15 to 20 mph with stronger gusts will also reduce visibility. Temperatures are expected to drop into the mid-to-upper-20s across northwest Oklahoma, further allowing any winter precipitation that may fall to become extremely dangerous as it makes the roads slick. Please drive with extreme caution if you must be out overnight or Thursday morning in this region. In some areas, especially the panhandle, temperatures may not rise above freezing on Thursday. WINTER STORM WARNINGS and WINTER WEATHER ADVISORIES remain in effect through Thursday afternoon/evening.

The wintry weather situation may be worse in NORTHEAST OKLAHOMA. Freezing rain is expected across this area as temperatures drop at or slightly below the freezing mark to the upper-20s overnight. Expect a wintry mix of precipitation (rain, snow, sleet, and freezing rain) before midnight, then freezing rain for the remainder of the night and continuing through mid-Thursday morning. By the afternoon, all areas in northeast Oklahoma will see any wintry precipitation change over to all rain as temperatures "warm up" into the mid-to-upper-30s. Though these highs are not much warmer than the overnight lows, they are still warm enough to prevent any further ice from forming. Note that WINTER STORM WARNINGS and WINTER WEATHER ADVISORIES remain in effect until Thursday afternoon/evening.

CENTRAL OKLAHOMA will see a wintry mix of precipitation (rain, snow, sleet, and freezing rain) after midnight continuing on through early morning. Then, all wintry precipitation will change over to rain. Some thunder is also possible. By the afternoon, all precipitation will end, and skies will begin to gradually clear. Expect high temperatures to rise into the upper-40s to low-50s, melting any wintry precipitation that has fallen. Any snow, sleet, or ice accumulations will be minimal across this region. Some WINTER WEATHER ADVISORIES are still in effect until noon Thursday, however, so please take caution when travelling.

Most of SOUTHERN OKLAHOMA will not see any wintry precipitation but rain showers and thunderstorms instead. Storms may be SEVERE in extreme southwestern Oklahoma, producing large hail and damaging winds. All rain and thunderstorms should end by mid-afternoon, and we'll see temperatures rise to the mid-to-upper-50s as skies begin to clear.
