Much of the CONUS experienced good overnight humidity recoveries
alongside accumulating 24-hr precipitation across the Great Basin,
Southwest, and Great Plains. On the western periphery of an upper
ridge over the Southeast, several shortwave trough impulses will
promote scattered rainfall across the lower MS River Valley and
Mid-South. This will aid in the recovery of drought-stressed fuels
across the region with additional precipitation chances arriving
middle of next week. The lack of dry and windy conditions where dry
fuels exist will maintain a reduced fire weather threat today.

...Discussion...
An amplifying upper trough over the Intermountain West will eject
into the Great Plains on Day 3/Monday. A deepening surface low in
the northern Plains will increase southerly flow, advecting rich
eastern Pacific and Gulf moisture into the central CONUS. Leading
large-scale ascent and an eastward progressing cold front will
promote widespread precipitation across portions of the central to
eastern states through the end of next week. This should bring much
anticipated relief to dry fuels in the lower MS River Valley (and
perhaps the southern Appalachians). Extended guidance indicates an
unsettled troughing pattern and cooler temperatures will persist
over the western third of the CONUS through the forecast period.
Thus, any threat of significant fire weather remains low across
almost all CONUS locations.
