Discussion: The just-issued 0600 GMT GFS operational model is fiery hot with a 105.4 U.S. CDD total (67 is normal) for the (natural gas) week ending July 5. The demand is amplified by Northeast U.S. heat (Fig. 1) including a super heat wave in Boston featuring 92-97F for most of June 29-July 6 (Fig. 2). The forecast is likely too hot but the trend toward the implied heat is correct.
