...Synopsis...
A ridge of high pressure will transition into the western CONUS,
bringing warmer temperatures and a lighter wind regime to California
and the western Great Basin today. The center of an eastward
progressing mid-level low will enter New Mexico, gradually weakening
as it becomes reincorporated within broader troughing. Southerly
flow will deepen ahead of the low, providing ample moisture
transport bringing PWAT values above the 95th percentile across much
of the central CONUS into the Upper Midwest. This system will induce
widespread precipitation over an environment stressed by long-term
drought, particularly across portions of the southern Plains and the
New Mexico/Colorado Rocky Mountains. Ahead of the advancing
moisture, a residual hot and dry airmass will remain in place across
the lower Mississippi River Valley and Mid-South where receptive
fuels exist; however, light southerly winds of less than 15 mph
should limit a broader fire weather threat.
