...Stormy weather across the Plains and cool temperatures for the Rockies
and New England...

The severe weather potential is beginning to gradually diminish across the
central plains and Midwest, after an active day on Monday.  The threat of
severe storms on Tuesday will be across Missouri and Arkansas, and will
not be as widespread as yesterday, with SPC having an enhanced risk of
severe storms across this region.  With the surface low weakening on
Wednesday, the severe threat will not be as significant.  Additional heavy
rainfall will once again be an issue, with the potential for 1 to 3 inches
of rainfall through Wednesday from eastern Oklahoma to northern Missouri,
and this may lead to instances of flooding. 

To the north and west of the surface low, temperatures are forecast to be
10 to 25 degrees below average across the Four Corners region, the western
High Plains, and much of the Intermountain West through Wednesday.  Late
season mountain snow is likely for portions of Wyoming, Colorado, Utah,
and Montana, where at least a few inches of snow could fall at elevations
above 8000 feet through Wednesday.  Behind the cold front and dry line,
very low relative humidity and high winds result in dangerous fire weather
conditions mainly across southern New Mexico and far western portions of
Texas.
