**Current National Weather Service and model guidance indicate overnight lows in Dallas on October 4 will likely settle in the mid-60s°F under partly to mostly clear skies and northerly winds of 5–10 mph following recent showers.** High dew points near 65–70°F from lingering Gulf moisture will moderate radiational cooling, while the shift to drier northerly flow and reduced cloud cover after daytime heating supports temperatures dropping into the low-to-mid 60s by early morning. Historical October 4 normals place the average low near 63°F, providing context for the tight market split between the 61°F-or-below bucket and warmer outcomes; subtle differences in cloud timing, wind speed, or boundary-layer mixing could shift the minimum by a few degrees either way. Updated model runs and NWS briefings through the evening of October 3 will refine these variables ahead of the overnight period.
