...DISCUSSION...

Severe storms appear unlikely over the CONUS through the extended

forecast period. An upper low is forecast to deepen over much of the

eastern US while ridging develops over the West. This will amplify

the overall pattern with strong northwesterly flow likely over much

of the central US. In response, a strong cold front and very deep

surface low will move offshore scouring available surface moisture

from the central US midweek next week. The persistent eastern US

troughing and high pressure in the wake of the cold front over the

central US will favor cooler, drier and more stable surface

conditions through the remainder of next week.
