Strong Heat Event to Bring Cooling Degree Day Records This Week

GAITHERSBURG, MD - (June 12, 2017) A drastic change in the weather pattern brought near record high cooling demand to the Midwest and Northeast this past weekend and through much of this week. Readings in the low to mid 90s F began this weekend in the Midwest, including Chicago where the MDA Weather forecast has 90F or better each day from Saturday through Tuesday. The East likewise sees a prolonged period of heat this week, with the current forecasted Energy Information Administration (EIA) week ending June 15 featuring the highest national Population Weighted Cooling Degree Day (PWCDD) total for the period on record. This EIA forecast includes peaks early in the week in the mid and upper 90s F in Philadelphia, Washington D.C. and Richmond. Temperatures in the 90s F are forecast from Sunday through Thursday in Philadelphia and Sunday through Saturday in Washington D.C. this week. 

“A strengthened Bermuda High will be the catalyst for the upcoming heat wave,” says Bradley Harvey, Lead Meteorologist at MDA Weather Services. He adds, “PWCDD totals are forecast to rank near period records in the EIA week from June 9 to 15 not only nationally but also regionally in MISO, NEISO, NYISO and PJM.”

The current national PWCDD total for the period of June 9-15, 2017 is 70.42, the highest for the period since 1950.
