US Morning Demand Note, Thursday, 16 July 2026

US Morning Demand Note, Thursday, 16 July 2026 A national 15-day gas-weighted CDD load of 208, sitting 84 units above seasonal normal, keeps the broader demand picture constructive even as the latest run trims 12 units from yesterday's estimate. The divergence between a cooling southern and western load and a softening northern one tells the underlying story: the ridge that has been sustaining above-normal heat is not retreating uniformly. The synoptic picture is a split regime. Across the southern tier, the pattern is intensifying, ERCOT and the South/West corridor are both running hotter in the new update, not cooler, with ERCOT adding 39 CDDs run-to-run (now 394 against a 172 normal, an anomaly of 222 units) and the South/West similarly extending. That is consistent with a ridge axis holding or nudging westward, concentrating heat across the Gulf Coast and interior West. The Midwest and Northeast tell the opposite story: both zones shed CDDs sharply, the Midwest down 26 and the Northeast down 31 on this run. The widest single-day revision in the 15-day strip falls on 29 July, where the models pulled back 3.1 CDDs, pointing to a meaningful model disagreement over whether the ridge sustains into the back half of the period or allows a trough to undercut from Canada. Until that question resolves across successive runs, the northern hub outlook carries more uncertainty than the southern one. For market pricing, the zones matter as much as the national aggregate. ERCOT at 222 CDDs above normal is the dominant signal, the power burn and regional gas pull from that zone alone is material for the South/Southeast gas flow balance. HSC and Waha are caught between that heat load on the demand side and Permian supply dynamics on the supply side; the CDD print supports the demand leg. SoCal similarly benefits from the western ridge extension, with the South/West anomaly at 181. Chicago Citygate and MISO are the relative soft spots, and at 80 CDDs above normal the Midwest still runs well above seasonal, but the directional trend on this run is lower, if the back-half trough scenario gains traction across the next one or two model cycles, that zone's forward cooling load will be marked down further. The market read remains supportive across both the gas and regional power complex, with cooling burn above normal the operative mechanism. What changes the picture: watch whether the southern ridge extension in tomorrow's runs confirms or stalls, a third consecutive run adding to ERCOT and South/West CDDs would represent genuine model convergence and firm up the back-half load. Conversely, if the 29 July gap widens further and the Midwest/Northeast trim deepens, the national aggregate could erode toward normal faster than today's strip implies, softening the northern hub picture materially while leaving the southern load intact.
