Summary

• A single mid-March pattern is producing multiple weather extremes across the United States at once, including blizzards, strong winds, heat, heavy rain, and drought.
• Jet stream variability remains the main atmospheric mechanism used to explain the spread of regional extremes.
• Warm Pacific waters are repeatedly cited as an amplifier, especially for Hawaii rainfall and broader spring volatility.
• Drought still covers a large share of the country, and western fire risk is rising as heat and dryness persist.
• Climate change is framed as an enhancing factor, but the reports also preserve a strong role for natural weather variability.
• The topic is coherent and current, with little historical material and a dense concentration of near-term weather impacts.
