...DISCUSSION...
Severe potential is low through the extended forecast period. A
strong upper trough and jet over the central US will merge with a
broad upper low over the eastern US midweek. At the same time,
ridging will develop over the West, as the flow pattern aloft
amplifies significantly. This will drive strong northwesterly flow
across the central CONUS. An associated cold front will sweep
through the central and eastern US before moving offshore D4/Wed. As
the front moves offshore, a deep coastal low is expected to develop
and could promote isolated thunderstorm activity along the East
Coast or south FL late this week and into the weekend. However, the
persistent eastern US troughing and strong surface high pressure
behind the cold front will favor much cooler, drier and more stable
surface conditions across the CONUS. Thus, thunderstorm chances are
low with little severe risk through the extended forecast period.
