What this means if you live in Dallas: neither drought nor hard freezing is an aggressive force on foundations here right now: your county isn't in significant drought this week, and your winter stays mild enough that freeze-thaw heaving is limited. That doesn't make a foundation maintenance-free — poor drainage and plumbing leaks move foundations in any climate — but the two big seasonal weather drivers are quiet for you at the moment. Because Dallas is our detailed-soil pilot, you can also look up the actual shrink-swell soil profile for your ZIP, which is what determines how hard these weather forces actually hit your specific lot.
What do the drought categories (D0–D4) mean?
They're the U.S. Drought Monitor's official national scale, released weekly: D0 is "abnormally dry," D1 moderate, D2 severe, D3 extreme, and D4 exceptional drought — the most intense. The percentage above is the share of your whole county sitting in D2 or worse, which is the range where expansive clay soils dry and shrink enough to stress a foundation. It's a real, current reading, not a historical average, so it changes week to week as conditions do.
Drought: U.S. Drought Monitor (NDMC/USDA/NOAA), most recent weekly release for Dallas County. Freezing-day counts: NOAA National Centers for Environmental Information, 1991-2020 Climate Normals. Comparison figures are computed across the metros ClearPick tracks, not a national survey. The clay-shrink mechanism applies specifically to expansive clay soils; a local inspection is the only way to confirm your lot's actual soil and risk.
