Rows marked NWS are NWS's own day (≈6a–6p) and night (≈6p–6a) periods. NWS is also one weighted source inside the blend values. Every other value uses the same sources, weights and calculation as its tool page: temperatures, precip and gusts from MODEL BLEND (models, ECMWF ENS, GEFS and NWS, using the blend recipe you picked there), snow chances from WINTER, the thunder signal from THUNDER. Change a model's weight on a tool page and this summary follows it. Overview cards use the printed local planning periods, with night lows and daytime highs explicitly labeled. At 2 PM, tonight and tomorrow lead; a smaller rest-of-today summary remains visible until 5 PM. Partial current-hour precipitation is counted in full and may include the elapsed part of that hour. The daily Blend table retains calendar days, so it can differ from these period values.
