Temperature anomalies do have a marginal effect on NG net injections. As Hal noted, todays storage # was near or slightly below consensus, and low for the season, pointing indeed to the marginal effect of temperatures since, for the week in question, most of the eastern half of the country was in an early heatwave. This week, although the SE and Gulf states have remained anomalously warm, the big Philidelphia to Boston market was near seasonable or even a few degrees cooler than that. So next week's storage report I expect will show an injection slightly above the consensus estimate and near the seasonal average value.
If we are to believe the 14 day forecast, warm weather will return to much of the NE during the next 2 weeks, and so the injection report for June 30 should indicate a marginally below consensus number, and a generally low storage number for that point in the season.
The tropical storm issue is the elephant in the room. One model is hinting at some development in the SW GOMEX late next week, but these type of forecasts have a high false-alarm rate. I'll keep anyone who's interested posted.
