An upper-level disturbance and an associated inverted surface trough will produce heavy rain across
the Northeast between Thursday and Friday this week. A deep upper-level trough will amplify and
produce heavy rainfall over much of the Central US between Friday and Sunday. An occluded surface
low pressure system associated with the upper-level trough will develop over the Northern Plains
and propagate eastward toward southern Quebec through Monday. There's a chance for severe weather
over the Central Plains and Middle/Upper Mississippi Valley on Friday as a result. There's a strong
signal of rainfall exceeding 1.5 inches across the Central Plains and Midwest as the cold front
associated with the surface low tracks across the nation's midsection this weekend. The threat for
heavy rainfall will persist across the Central US into the beginning of next week. Heavy rainfall
is likely over parts of the Central US, while particularly heavy rainfall in excess of 4 inches are
possible for parts of the Central Plains and Middle Mississippi Valley this weekend, where flooding
from the Mississippi and Missouri Rivers remains a concern.
An upper-level ridge will cross the central states on Wednesday leading to above normal
temperatures for parts of the Southern Plains through next Monday. An area of excessive heat is
likely for southern Texas where heat indicies could exceed 105 degrees. No major hazards were
issued over Alaska.
