In a warmer climate, the fraction of annual meltwater produced at high melt\udrates in mountainous areas is projected to decline due to a contraction of\udthe snow-cover season, causing melt to occur earlier and under lower energy\udconditions. How snowmelt rates, including extreme events relevant to flood\udrisk, may respond to a range of warming over a mountain front is poorly\udknown. We present a model sensitivity study of snowmelt response to warming\udacross a 3600 m elevation gradient in the southern Sierra Nevada, USA. A snow\udmodel was run for three distinct years and verified against extensive ground\udobservations. To simulate the impact of climate warming on meltwater\udproduction, measured meteorological conditions were modified by\ud+1 to +6 °C. The total annual snow water volume\udexhibited linear reductions (−10 % °C<sup>−1</sup>) consistent with\udprevious studies. However, the sensitivity of snowmelt rates to successive\uddegrees of warming varied nonlinearly with elevation. Middle elevations and\udyears with more snowfall were prone to the largest reductions in snowmelt\udrates, with lesser changes simulated at higher elevations. Importantly,\udsimulated warming causes extreme daily snowmelt (99th percentiles) to\udincrease in spatial extent and intensity, and shift from spring to winter. The\udresults offer insight into the sensitivity of mountain snow water resources\udand how the rate and timing of water availability may change in a warmer\udclimate. The identification of future climate conditions that may increase\udextreme melt events is needed to address the climate resilience of regional\udflood control systems
