...Heavy rainfall and severe weather possible across portions of the Lower
Mississippi Valley and Deep South...
...Heavy snowfall possible across the higher terrain of the Intermountain
West and into the Northern Plains Monday and Tuesday...
Widespread showers and thunderstorms are expected along and ahead of a
frontal boundary as it moves through the Mississippi Valley today and into
the Ohio Valley and Eastern seaboard states by Tuesday. The heaviest
rainfall is expected across portions of the Lower Mississippi Valley into
the Tennessee Valley on Monday and again on Tuesday into Wednesday as the
southern portion of the boundary stalls and a second system approaches
from behind. WPC is highlighting a marginal to slight risk for excessive
rainfall across these regions on both days. In addition to the heavy
rainfall, plenty of instability along and ahead of the boundary will allow
for organized strong to severe thunderstorms across the same area, with
the Storm Prediction Center forecasting an enhanced risk on Monday, and
slight risks Tuesday into Wednesday from eastern Texas to Alabama.
Cold air and upper level dynamics on the backside of the surface low in
the Upper Midwest from this initial system will allow for heavy snowfall
across portions of the Northern Plains on Monday. A second system on its
heels however keeps the threat for heavy snowfall across not only the
Northern Plains but also much of the interior West and Rockies through
Wednesday. Winter storm warnings, watches, and winter weather advisories
are in effect across much of the Northern Plains as well as the higher
elevations of the Rockies and Intermountain West. Gusty winds across the
entire region are also expected to create blowing snow and hazardous
travel conditions.
As one storm exits the mountains, another makes its way onshore across the
Pacific Northwest. Another round of rain and higher elevation snow is
possible across much of the Northwest by Wednesday.
