EDT March 22 2019
Synopsis: The main weather hazard during Week-2
is expected to be heavy precipitation from a low pressure system that develops
in the lower Mississippi Valley and moves northeastward into New England by the
end of the forecast period. There is also a slight risk of much below normal
temperatures throughout the Plains early in the week, Mar 30-Apr 2, and heavy
precipitation in northern California at the beginning of April.
Moderate risk of heavy precipitation for the
Lower Mississippi Valley, Sat-Sun, Mar 30-31.
Slight risk of heavy precipitation for most of the eastern CONUS, Sat-Fri,
Mar 30-Apr 5.
Slight risk of heavy precipitation for parts of northern California,
Mon-Tue, Apr 1-2.
Slight risk of much below normal temperatures for the northern and central
Plains, Sat-Tue, Mar 30-Apr 2.
For Saturday March 30 - Friday
April 05: The main weather event during the Week-2 forecast period is
likely to be a low pressure system that develops in the Southeast early in the
period and moves its way northeastward during the week. There is generally good
model agreement regarding the development of the low and the broad region of
heavy precipitation that goes along with it. There is a slight risk of heavy
precipitation posted for the eastern CONUS during the entire forecast period.
We have also posted a moderate risk hazard for heavy precipitation over the
Lower Mississippi Valley on Mar 30-31. Although the exact timing and extent of
the heaviest precipitation after Mar 31 is difficult to pinpoint at this time,
the core of the heavy precipitation threat is expected to move northeastward
out of the Mississippi Valley by Apr 1 and continue into New England by the end
of the period. There is also the possibility for heavy precipitation over parts
of northern California Apr 1-2 as low pressure off the West Coast slides
Colder temperatures are forecast to overspread the Plains southward to
roughly the Texas/Oklahoma border, Mar 30-Apr 2. Many of these overnight
temperatures could be below freezing.
