Cold and getting colder

Everyone knows that it’s getting colder when December rolls around, so to start the month with a forecast that feature descending temperatures is insult to injury. It’s made worse by forecasts being warmer than what ultimately verified, as was the case in Tulsa at the beginning of the month. A cold front that was unencumbered with moisture brought brisk winds and chilly temperatures progressively through our forecast period. It started colder than expected and stayed that way. Accuweather had the best line on the chilly weather, not that it was a great forecast.

Today’s forecast takes us to another part of the country that is known for strong spring time weather, after Decatur earlier this week. Will Tulsa see cool and calm like Decatur did, or will we see something different?

At 953AM, Tulsa was reporting a brisk 42 degrees with mostly cloudy skies and wind gusting over 20mph. The jet was quite strong, which is not unusual for the time of year, and ridging through the center of the country. High pressure centered over the Ohio Valley was generating the brisk wind on it’s back side, with return flow bringing some of the cloud and chances for rain in the southern Plains.
Over the Rockies, this same strong jet is producing a trough, which hasn’t fully materialized into a surface low yet, thanks to the local terrain. Expect a deep area of low pressure to emerge over South Dakota tomorrow morning, enhancing the windy conditions over Tulsa. Flow will be from the southwest, with high pressure still nosing into the northern Gulf, and this will staunch moisture flow into Oklahoma. The associated cold front will arrive late Friday with similarly gusty winds, and a significant Saturday cool down.

The high on Saturday will probably come at midnight. The WeatherNation hourly forecast doesn’t extend that far out, but they shouldn’t be too far off. Check out the satellite, showing clouds wrapping around high pressure in Texas and Oklahoma.

Tulsa, Oklahoma

Tonight we head to the Southern Plains to see how Tulsa is setting up for the rest of the workweek. Will the Golden Hurricanes of the namesake university see a peaceful couple of days? Or is there a tempest brewing?

At 1053pm CST, the temperature at Tulsa, OK was 63 degrees under partly cloudy skies. An area of low pressure is working through the Midwest, trailing a cold front through the Southern Plains that will bring rain showers and a few scattered thunderstorms during the day. However, temperatures will be falling throughout the day as cooler air works in from the morning as high pressure works down into the Northern Plains. As the boundary continues to push south Thursday into Friday morning, a few lingering rain showers are anticipated over the region, though the heaviest activity looks to be off to the east. Conditions should dry up as the day goes on, but even cooler temps will work their way into the state as high pressure pushes further south over the Central Plains.

Thursday: Chances of showers and thunderstorms. High 62, Low 42.
Friday: Widespread showers. High 41, Low 34.
