G2 Weather Signal™ Report: March 23, 2026
The roof is on fire ...
“It is said that the darkest hour of the night comes just before the dawn.” —Thomas Fuller
Spring arrived this week in the data before it arrived on the calendar. A broad heat wave is running across most of the country — the West and Southwest are 15–20°F above normal, the interior is accelerating, and even the Northeast has flipped positive YoY. For Q1, the weather environment is broadly improving heading into Easter.
The forward signal holds through April. Above-normal temperatures are the base case across most regions for the full month. The one exception that matters: the Northeast, the country’s highest-revenue retail market, is forecast near-normal after a warm April last year — a softer setup than it looks on the surface.
Precipitation is the variable to watch. Wet conditions in the Northeast this week are suppressing foot traffic despite the temperature recovery. The pre-Easter cold snap in the Southeast next week is the sharpest near-term adverse signal in the dataset — Charlotte, Atlanta, and Philadelphia all in the bottom five heading into the most important shopping weekend of the spring.
The weather signal is as clean as it gets right now. But it needs to be read inside a fragile economic environment. The administration’s military escalation in Iran has pushed gas prices sharply higher and introduced a level of consumer uncertainty that the weather model doesn’t capture. Favorable weather is a necessary condition for spring demand — it is not a sufficient one when consumers are watching prices at the pump and questioning what comes next.
This week’s Flash Report covers three time scales: last week’s actuals (NRF Week 8), this week’s in-progress forecast (NRF Week 9 — the dominant signal for Q1), and next week’s pre-Easter outlook (NRF Week 10).
The extended NOAA Week 3-4 probability outlook and the full April monthly forecast — with year-over-year comparisons against April 2025 actuals — are included for subscribers, along with the company-level Q1 weather signal for Home Depot, Lowe’s, Costco, BJ’s Wholesale, Ross Stores, and Burlington.
The weather signal accounts for the weather environment. What it cannot account for is a consumer who is paying more than $4 at the pump and reading headlines about military engagement in the Middle East. Both things are true this week.
The signal is favorable. The backdrop is not.
