Dear Restaurant Operators and Energy Managers,

Here’s your concise, actionable weekly briefing: a potent spring storm system tracks across the central US mid-week with elevated severe thunderstorm potential, while a cold front brings below-normal temperatures to the North and a warm ridge holds in the South and Southwest. This creates HVAC mode-switching pressure and targeted storm risks amid otherwise favorable patio conditions.

Severe Weather & Storm Alerts

Hurricanes or Tropical Systems: None active or forecasted for the continental US in the next 21 days. Likelihood of any impact: <1%.

Tornado & Severe Thunderstorm Risks:

• 7-Day (Apr 27–May 3): Quiet start. Slight Risk Wednesday–Thursday (Apr 29–30) across the central Plains into the Midwest and Ohio Valley for large hail, damaging winds, and isolated tornadoes. Cities: Kansas City MO/KS, St. Louis MO, Chicago IL, Indianapolis IN, Louisville KY. Likelihood: 20–35% any severe thunderstorm; 5–15% tornado in Slight-risk corridor. Risk drops sharply by weekend.
• 14-Day & 21-Day: No organized outbreak signals. General spring severe potential stays moderate. Regional likelihood of a notable severe day: 10–25%.

Restaurant Impact: Mid-week wind/hail threats to outdoor seating, signage, and refrigeration in the central corridor. Likelihood of operational disruption (brief outages or patio closures): 15–25%. Secure equipment early.

Extreme Temperature Alerts & HVAC Impacts

Extremes defined as: highs >95°F, lows <40°F, or departures ≥15°F from late-April seasonal averages. These trigger rapid HVAC load swings and efficiency drops.

7-Day (Apr 27–May 3): Cold front North, warm ridge South/Southwest.

• Cold extremes (lows <40°F + ≥15–25°F below avg, likelihood 55–75%):
  • Minneapolis MN, Milwaukee WI, Detroit MI, Chicago IL: lows 28–38°F.
  • Northeast corridor (Boston MA, New York NY): lows 32–40°F.
• Hot extremes (highs >95°F + ≥15°F above avg, likelihood 40–60%):
  • Phoenix AZ, Las Vegas NV, San Antonio TX, Houston TX: 95–102°F peaks.
• HVAC Impact: Northern locations face renewed heating demand and potential system strain. Southern/Southwestern sites see climbing AC runtime. Energy volatility risk: moderate-to-high (45–65%).

14-Day (~May 4–10): Transition toward above-normal temperatures across the eastern and southern US. Northern cool-down eases. Likelihood of sustained mild/warm pattern: 60–75%; notable anomalies ≥15°F above avg: 45–65%.

21-Day (~May 11–24): Above-normal temperatures favored across the southern tier, Southeast, and West (per CPC). Likelihood of continued warm anomalies: 55–70% most areas; ≥15°F departures in southern/western zones: 40–60%. Cold extremes unlikely (<15%).

Restaurant Impact Summary: Mid-week storms add localized risks in the Midwest/Ohio Valley, but the temperature split drives heating costs North and cooling costs South. Longer-range warmth should ease loads and boost outdoor traffic.

GWT2Energy Recommendations:

• Perform quick heating-system checks and filter changes in Upper Midwest and Northeast markets ahead of the cold snap.
• Schedule AC coil cleaning and refrigerant checks in Phoenix, Las Vegas, and Texas locations.
• Monitor SPC for Wednesday–Thursday severe risk and prep generators/outdoor assets in central corridor cities.
