Prediction for September 19, 2017

Posted to the Web September 18, 2017, 6:05 PM EDT.

Change in Futures (Avg.): +0.006

Change in 2nd-Lowest Retail (Avg.): +0.019

Pressure: (Avg.): +0.022

Trend for tomorrow: Up

Trend for next 2-3 days: Up

Recommendation for tonight: Buy gas tonight.


  1. Average pressure is very weakly upward, but the local picture is getting complicated again. The strongest downward pressure is in cities where retail prices rose sharply over the weekend, but there is also regional downward pressure in the Southeast. Check your local prediction, but on average, retail prices are going up a little bit tomorrow.
  2. We have mixed pressure tonight. Nine cities in our national model have upward pressure, two have steady pressure for tomorrow with downward pressure for the next 2 to 3 days, and one has downward pressure. Although the numerical average pressure is very weakly upward, it is still possible for the average retail price to move downward tomorrow. Today's average price among our 12 cities is $2.669 per gallon, and our predicted price range for tomorrow is 2.666 - 2.684. We will call this a successful prediction if the average price moves upward (regardless of how much) or if it moves down as far as $2.666.

Why bother? Gas prices are just going up and up, so what's the big deal about a prediction? Prices are simply going up and there's nothing you can do about it, right? Not really! Once in a while, prices halt in their upward trend, and even move downward. That is your opportunity to save money on gas. If you know when prices are going to fall, you can make sure you have room in your tank to take advantage of it. Or if you know prices are going up tomorrow, you can fill up before they rise. And that's what is all about!
