Busy Weather Pattern Next Week
After some drier weather in the last 10 days or so, the weather pattern is
forecast to become much more active next week, especially in the Midwest.

Early March was an active period that saw some really good precipitation
across the middle of the country. However, it wasn't enough to eliminate a lot
of drought across the Plains, South, or Southeast, which grew during the last
two weeks as the pattern became drier. But the weather pattern will be changing
again for the last couple of days of March and early April, a pattern that will
feature multiple systems moving through the country, widespread precipitation,
heavy rainfall and severe weather chances.
The last 10 days or so have featured a hot and dry upper-level ridge across
the West and Central, which has been the source of some record heat. But that
ridge will shift eastward and out of the United States next week. That will
open up the country to more weather systems, fronts and features that will
promote more widespread precipitation across the country.
That begins with a system moving into the Plains on March 30. Models
disagree with how widespread showers will be with this first impulse, but
additional impulses will move from the West through the Central and into the
Northeast through the rest of the week and into Easter weekend.
Overall, rainfall will target some places like the Midwest over others like
the Southwest or Southeast, where drier conditions are more likely than not.
Still, these areas may get lucky with at least some precipitation next week,
but the heaviest precipitation is likely to favor the middle of the country.
Even there, though, it may not favor the areas most in need of
precipitation. As the U.S. Drought Monitor showcased on its most recent update,
https://droughtmonitor.unl.edu/, drought has expanded significantly across the
Interior West, Central and Southern Plains, South and Southeast this week. Many
areas of D3, extreme drought, and some areas of D4, exceptional drought cover
vast areas of the country. Widespread, heavy precipitation is certainly needed
this spring, as many of these areas are dealing with significant deficits
during the last six months or longer.
Though the pattern will bring through plenty of opportunities for
improvement, those deficits will not be made up by a week of busy weather. And
not all areas are likely to be hit. Some areas of the southwestern Plains and
Southeast are unlikely to see much precipitation, and drought may worsen in
this busier pattern. In contrast, some areas that are not seeing drought could
see flooding after several consecutive days of thunderstorms, particularly in
the Midwest.
To go along with the heavier rain potential, severe weather looks like a
distinct possibility with each of the impulses moving through the country.
These impulses are not well forecast at the moment, and thus the areas of where
severe weather may occur will likely shift during the coming days. But given
that, there may be areas of severe weather east of the Rockies from Monday
through at least Saturday, April 4, allowing for many areas to be threatened by
strong thunderstorms.
While much of the focus is on precipitation and thunderstorms, temperatures
will eventually be low enough for some areas across the Northern Plains and
Upper Midwest to experience some accumulating snow. It may take until late in
the week for enough of the cooler Canadian air to move south to allow for the
snow, but this will be a possibility as well.
The active weather pattern may not stop at Easter weekend, either. Models
are insistent on multiple systems moving through the country through at least
the middle of April. It is too early to tell if there will be more help for
those areas in drought or not, but keeping an active pattern going is at least
giving these areas a chance to improve.
