The seasonal anomalousness, as well sheer spatial extent, of upcoming record-shattering Western U.S. heatwave is genuinely startling. This will be associated with, by far, the strongest ridge ever observed during (at least) any Nov-Mar month. #CAwx #AZwx #NMwx #NVwx #UTwx #COwx
In fact, this will approach the Jun 2021 PacNW/BC heat event in terms of meteorological anomalousness (though not, fortunately, in terms of absolute surface temperatures. It is still *March*, after all!) Western snowpack, however, will plummet at an unprecedented pace.
