...Synopsis...
In the wake of a robust midlevel trough and attendant cold front
moving from the Rockies into the Plains, strong westerly surface
winds and 25-35 percent RH will overspread the southern High Plains
during the day. However, preceding rainfall atop already unreceptive
fuels will limit fire-weather concerns. Elsewhere across the CONUS,
a minimal overlap of dry/windy conditions will also limit
fire-weather concerns.

...Discussion...
An amplified upper trough will translate over the Great Plains into
the Upper Midwest on Day 3/Tuesday, advecting abundant Gulf moisture
into the MS Valley. An attendant surface low will traverse the Great
Lakes region into southeastern Canada through the week, sending a
cold front across the central to eastern states through Day
5/Thursday. Along the front, widespread precipitation is expected to
bring much anticipated relief to drying fuels in the Appalachian
Mountains. A shortwave trough will trail the main trough on Day
5/Thursday, bringing additional precipitation chances to the
southern Plains. In the wake of this system, much of the Interior
West to south/central U.S. will be under northwest-westerly flow
aloft, maintaining near-average temperatures and mostly dry
conditions. Extended guidance indicates the potential for another
shortwave trough to dive into the Great Plains next weekend;
however, ambiguity in model trends yields low confidence in the
progression of the overall pattern. Nevertheless, fire weather
concerns will be reduced across almost all CONUS locations through
the forecast period.
