US Morning Demand Note, Sunday, August 2, 2026
EnergyReader.io | Pre-Open ~6:40 ET
The dominant signal this morning is a national heat anomaly running roughly double normal across every major demand region, a broad, synchronous pattern that is extending and intensifying on the latest model run.
The 15-day gas-weighted CDD total has printed 236 to 246, a delta of plus-10 against a normal of 116. That 130-unit anomaly is not concentrated in one region, every tracked zone is running well above climatology simultaneously, which points to a persistent upper-level ridge anchored over the central and eastern US rather than a transient heat plume. The key synoptic question into next week is whether that ridge axis holds its position or begins to elongate eastward under the influence of any emerging Atlantic trough. If the ridge maintains its current geometry, the anomalies in the Northeast and Midwest, both running well over 100 CDDs above normal, will continue compounding through the medium range. If the axis sheds east, the interior heat relaxes first while coastal demand remains sticky. The run-to-run signal on this evolution is the one to watch: the widest daily divergence between model runs is concentrated at August 13, where consecutive-run disagreement touches 5.3 CDDs in a single day, that date is the current inflection point and where pattern confidence thins.
Zone-by-zone, the demand story is consistent but the mechanisms differ. The Northeast is the sharpest mover this run, printing plus-14 on its 15-day CDD revision and now running 132 units above normal against a sigma of 16, that is a statistically extreme anomaly for Algonquin and TETCO M3 pricing. Any ridge persistence that keeps the upper high parked over New England sustains power burn at levels that price pipeline capacity tightly. The Midwest tracks similarly, up 13 on the run with a 107-unit anomaly; Chicago Citygate and MISO are both lit, suggesting the heat is deep enough into the interior to sustain sustained coal and gas displacement dynamics in the power stack. ERCOT is the one zone that pulled back on this run, off 8 CDDs, but its absolute anomaly of 225 against a sigma of 24 still places it in extreme territory; the revision is a magnitude adjustment, not a regime shift. South and West combined added 7 CDDs and sits 184 above normal, with Transco Z4 and SoCal both receiving the signal; the western component bears watching if the ridge axis shifts, as SoCal heat is more sensitive to offshore flow patterns than to the central US upper high directly.
The picture changes materially if the August 13 model spread begins to resolve, three consecutive runs in the same direction would either lock in the extended heat or signal the ridge is losing amplitude sooner than the consensus currently prices. A secondary signal to track is whether the ERCOT pullback this run is the leading edge of a broader southern ridge erosion or simply intrarun noise at a high-anomaly base. Any model convergence on the ridge exit timing is the primary variable from here.
