quick_answer: Quick answer: On I-30 between Dallas and Fort Worth, rain costs you through slower speeds, more crashes, and the first-rain slick. Add 30–50% to expected drive time in steady rain, more at peak. If rain is forecast for 4:30 p.m., leave thirty minutes early. Do not reroute first.

faqs[5]{q,a}:
  Does rain make Dallas–Fort Worth traffic worse?,Yes. Rain slows speeds, raises crash rates, and the first rain after a dry spell is the slipperiest. A reasonable planning rule: add 30–50% to expected drive time in steady rain, and more if it hits a peak period.
  When does weather hurt I-30 the most?,When a moderate storm arrives during the evening peak, around 4:30–6:00 p.m. The same rain that costs about five minutes at 11:00 a.m. can cost twenty-five at 5:00 p.m. because the corridor has no spare capacity.
  What weather actually disrupts this corridor?,Spring convective lines and hail (March–June, often late afternoon), flash flooding in underpasses, rare ice on elevated I-30 (December–February), summer heat breakdowns, and crosswinds on the open mid-corridor.
  Should I reroute or leave early when rain is forecast?,Leave early. Forecast rain during peak: shift departure, do not hunt for a clever detour first. I-20 is the better wet-weather default if you must change roads, because it usually has more spare capacity than I-30.
  Is the TRE a weather backup?,For downtown-to-downtown trips Monday–Saturday, yes. Scheduled TRE runs stay about 60–70 minutes in rain. TRE does not run on Sunday except during the State Fair, so a bad-weather Sunday has no rail fallback.
