text_A: Average daytime highs are in the mid 70s°F to low 80s°F (24–28°C) throughout the state in July, with overnight lows in the mid 50s°F to low 60s°F (13–15°C). January temperatures range from an average high of on the coast to overnight lows below in the far north and at high elevations. Average annual precipitation statewide is roughly with some variation occurring in the White Mountains due to differences in elevation and annual snowfall. New Hampshire's highest recorded temperature was in Nashua on July 4, 1911, while the lowest recorded temperature was atop Mount Washington on January 29, 1934. Mount Washington also saw an unofficial reading on January 22, 1885, which, if made official, would tie the all-time record low for New England (also at Big Black River, Maine, on January 16, 2009, and Bloomfield, Vermont on December 30, 1933).
text_B: From the way Mount Washington's temperature record is described in the passage, would New Hampshire have be justified in boasting to tourists that their state had recorded the region's lowest recorded temperature with the same level of verity as when Vermont made the same claim (with only the dates differing)?
NO.
