LONG TERM [Saturday through Wednesday]...
The extended period begins with a brief dry period through most
of Saturday with deep layer ridging over the region. Then, another
disturbance lifts northeastward from the Gulf ahead of a deepening
upper trough crossing the central plains late Saturday. Rain
returns to the forecast and continues into early to midday Sunday
when the axis of the upper trough swings into the southeast CONUS
shunting the moisture to our south and east. The mid/upper level
flow quickly transitions to zonal on Monday followed by ridging
Tuesday through Wednesday. At the surface, high pressure and a
very dry airmass will be in place Monday through the remainder of
the period. Temps will be near to slightly above seasonal levels.
