Dear Restaurant Operators and Energy Managers,

Here’s your concise, actionable weekly briefing: severe weather potential builds modestly mid-to-late week across the central US while a broad spring warm-up continues to favor above-normal temperatures across the southern tier and West. This pattern supports patio expansion but introduces isolated storm risks and growing early cooling demand.

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 20–26): Quiet early week. Marginal Risk possible Thursday–Friday (Apr 23–24) across parts of the central/southern Great Plains into the lower Midwest for large hail, damaging winds, and isolated tornadoes. Cities: Oklahoma City OK, Dallas-Fort Worth TX, Kansas City MO/KS, St. Louis MO. Likelihood: 10–20% any severe thunderstorm; 2–8% tornado in risk areas. Quiet before/after.
• 14-Day & 21-Day: No major outbreak signals. General spring severe potential remains moderate. Regional likelihood of a notable severe day: 10–20%.

Restaurant Impact: Brief wind/hail threats to outdoor setups and possible short power outages in the central corridor mid-week. Likelihood of operational disruption in risk zones: 10–20%. Secure patios and refrigeration backups.

Extreme Temperature Alerts & HVAC Impacts

Extremes defined as: highs >95°F, lows <40°F, or departures ≥15°F from mid-April seasonal averages. These accelerate cooling demand and strain early-season HVAC efficiency.

7-Day (Apr 20–26): Warm pattern dominates South and West.

• Hot extremes (highs >95°F + ≥15–25°F above avg, likelihood 45–65%):
  • Houston TX, Dallas TX, and southern Plains metros: 92–98°F peaks with record-challenging warmth.
  • Phoenix AZ and Southwest: continued 95–102°F.
• No cold extremes (lows <40°F or ≥15°F below avg) signaled.
• HVAC Impact: Rising AC runtime across the South/Southwest (efficiency drop 15–30% possible on systems transitioning from winter). Energy spike risk: moderate (40–60%) in affected zones.

14-Day (~Apr 27–May 3): Above-normal temperatures favored across the southern tier, western US, and Mid-Atlantic (per CPC). Likelihood of sustained warm pattern: 55–70%; notable anomalies ≥15°F above avg: 45–65%.

21-Day (~May 4–17): Mixed signals but above-normal probabilities lean highest across the western CONUS, southern tier, and Mid-Atlantic. Likelihood of continued warm anomalies: 50–65% most southern/western areas; ≥15°F departures in favored zones: 40–55%. Cooler signals possible in parts of the Northeast/Upper Midwest. Cold extremes unlikely (<10%).

Restaurant Impact Summary: Mid-week storms pose localized risks in the central US, but the broader warmth drives strong outdoor dining nationwide while increasing cooling costs and HVAC wear in the South and Southwest.

GWT2Energy Recommendations:

• Monitor SPC for Thursday–Friday central US storm threats and prep generators/patios in OK, TX, KS, MO markets.
• Prioritize AC tune-ups, coil cleaning, and filter changes in Houston, Dallas, Phoenix, and southern locations.
• Optimize setbacks and scheduling to capture efficiency gains from the mild pattern.
