A potentially unprecedented stretch of March heat is underway in Northern California. Daily records will easily be broken and all-time March records are within reach Tuesday through Saturday. Sacramento is also likely to tally up the most 80 degree days in any March going back to 1941. This unusually early heat has seasonal blooms and crops growing fast. Meanwhile the Sierra snowpack seems to be shrinking even faster. On Monday, the UC Berkeley Central Snow Lab said in a social media post that if current projections hold, the lab site could be without snow as early as the first week of April.Below is a summary of the records observed so far as well as the forecast from the KCRA 3 weather team.

Record-breaking high temps are forecasted for the next several days, which will accelerate snowpack melt.
Given current melt and lack of #snow in the forecast, we may see melt-out as early as the first week of April, ~5 weeks earlier than normal.#CAwx pic.twitter.com/icaa2Gi659

Next week’s weather pattern could challenge the record for warmest March day & most days in the 80s.
In those ways, this pattern would be unprecedented.
It’ll be uncomfortable for some, but the 1st stretch of high 80s usually is. Until we get out first stretch of high 90s. 😉 pic.twitter.com/qJiCxLCtC0

Spring is Northern California’s second-fastest warming season. This time of year is warming the fastest in Arizona, New Mexico and south Texas.
The climate science community is in strong agreement that increases in global temperatures are mostly being driven by human greenhouse gas emissions.
