Day 4-8 Convective Outlook

...DISCUSSION...
An upper ridge will likely prevail over the Four Corners region
through the upcoming weekend. Weak mid-level disturbances may rotate
around the apex of the upper ridge and impinge on a moist low-level
airmass across the Plains from Day 4/Friday through at least Day
6/Sunday. Although some severe potential may exist each day in
association with these subtle features, predictability remains too
low to highlight any areas of greater severe potential across the
Plains.

By late this weekend into early next week, medium-range guidance
generally suggests that the upper ridge will flatten as a more
pronounced shortwave trough advances eastward across Canada and the
northern tier of the CONUS. Strengthening mid-level winds associated
with this upper trough overlapping sufficient buoyancy may support
at least some severe thunderstorm potential across parts of the
northern Plains into the Upper Midwest from Day 6/Sunday into Day
7/Monday. However, there are still significant timing/amplitude
differences regarding the upper trough at this extended time frame.
Therefore, predictability appears too low to include 15% severe
delineations at this time.
