So I know we have been enjoying the cooler than normal weather and some of you might be wondering if this is a sign that we will have a cooler than normal start to fall?
Right now, I feel confident saying that we will end the last days of summer with above normal temperatures. The long range models agree that we'll experience a slow warming trend through the weekend with highs ranging from 85° to 90°. Normal high is 86°.
While the GFS continues to show above normal temperatures with highs near 90° each day through the 29th, the EURO shows below normal air filtering in on Monday the 21st.
THE GFS MAX TEMPERATURE FORECAST FOR 9-21-15:
The reason we see a difference between temperature predictions is because the GFS shows the trough staying north of The Deep South while the EURO shows the trough digging farther to the south and bringing us cooler air.
As of now, the EURO is trending towards a cooler than normal start to fall while the GFS shows above normal temperatures persisting until the end of the month.
We will keep watching the predicted positions of the troughs and ridges via both long range models and will let you know if the data synchronizes at any point. For now, it's hard to say if fall begins above or below normal. The first day of Autumn is Wednesday, September 23 (my nephew Caleb's bday)
