HAPPINESS

IS A WARM CUP

March 17, 2026 11:25 am

High pressure will strengthen this week with all-time record strong high pressure for March for most of the southwest states and surrounding areas for the latter half of the week will all-time record heat for March for inland areas. There will be weak offshore flow today with east to northeast winds gusting to 30 to 40 mph along and below the coastal slopes of the mountains. For Sunday into early next week, weakening high pressure aloft and onshore flow will allow cooling to spread inland, but with high temperatures remaining well above average, as much as 10 to 15 degrees above average through Tuesday of next week for inland areas.

An anomalously early heatwave begins to intensify and expand east across the western U.S.. Record cold across the Deep South this morning will shift into the Southeast by Wednesday morning. Deep cyclone and potent cold front exit New England early this morning with lake-effect snow gradually tapers off later today. Wet across western Washington states as light snow moves through the northern Plains and upper Midwest.
