Mixed precipitation — including some “thundersleet” — in the Texas Panhandle and around the southern Plains brought much-needed moisture to the region’s winter wheat crop, while snow fell in parts of the northern Plains and Midwest late Sunday and into Monday with some spots seeing totals of over a foot. The system in the southern Plains is expected to continue a northeastern march, taking precipitation through the region as temperature — especially in the upper atmosphere — helping determine whether that precipitation will be rain, sleet or snow. Meanwhile, high winds in the southwestern U.S. and California has fire danger spiking in three distinct areas from the Sacramento Valley to Los Angeles. See more on the weather to start the week.
