...Locally heavy rainfall possible across parts of the northwestern Great
Lakes as well as the Southern Plains...
...Severe thunderstorms possible across the Texas panhandle Monday...
...Well below average temperatures from eastern Colorado to the Upper
Peninsula of Michigan tomorrow...
A frontal system will slowly sink through the Rockies today and tomorrow
with mostly rain but locally heavy mountain snow. Much colder temperatures
are forecast for the foothills into the plains of Colorado tomorrow (about
25 degrees colder than Sunday) northeastward to Minnesota and Wisconsin
behind the front. As it continues southward into the Oklahoma and Texas
Panhandles, severe storms will be possible on Monday. The Storm Prediction
Center outlined a Slight Risk area around Lubbock. Heavy rain may
accompany these storms. Along the boundary to the northeast, rainfall may
be enhanced across parts of Wisconsin and into the Upper Peninsula of
Michigan as well, where present snow cover coupled with modest rainfall
could lead to some flooding. Temperatures to the south and east of the
front will be above normal by about 10-15 degrees over the mid-Mississippi
Valley into lower Michigan.
In the east, the frontal system that moved mostly offshore will invigorate
a trailing system later today that will spin up another area of low
pressure off the Mid-Atlantic coast tonight. That surface low will lift
northward toward southeastern New England tomorrow and bring a chance of
more scattered showers to the area. Though amounts will generally be
light, any additional rainfall could exacerbate ongoing flooding in Maine
due to snowmelt combined with the rainfall. Turn around, don't drown when
encountering flooded roads. Most flood deaths occur in vehicles.
