Even though there won't be much in the way of moisture to keep track of this week, the temperatures and winds will be telling the story.
First off, computer weather models are bringing in a dry cold front to Green Country Monday afternoon. This will be marked by a pronounced wind shift (see model graphic above in the media player). Southwest winds are forecast for the morning and then north breezy winds by the mid to late afternoon hours. They could gust up to 25 or 30 mph as the system moves in. Forecasting the high for Monday is a bit tricky because if the front is faster, it will be a bit cooler. If the front is delayed, highs will be warmer. As of now, we are forecasting 73° or 74° for the Tulsa metro area. One model computed 78° and another one had 72°.
Behind the front on Tuesday, highs will be in the mid 60s with lows in the 40s continuing.
The next front arrives Thursday into Friday dropping our highs to the 50s Friday through the weekend and lows for Saturday and Sunday around 32° in Tulsa, but outlying areas will easily have 20s. So be prepared for the first frost/freeze scenario on the way soon. As of now, models are not generating much in the way of precipitation, but we'll continue to refine the forecast as the week wears on.
