Note on Medium Range Outlooks

You are looking at an outlook that is part of the medium range forecast (the outlook for days 4-8). The most important thing to note is that lack of a risk does not mean zero risk. Generally speaking, confidence has to be pretty high for the Storm Prediction Center to have an outlook area this far into the future.

When no specific risk areas are shown, you might see one of these phrases:

DISCUSSION

D4/Sunday

The upper-level trough over the West is forecast to take on more of a positive tilt on Sunday, as an embedded shortwave and attendant midlevel jet maximum move across the northern Rockies/High Plains. As this occurs, a surface low is forecast to move from SD toward the upper Great Lakes, as a trailing cold front moves through the northern/central Plains. Guidance varies regarding frontal timing, though generally agrees that stronger mid/upper-level flow will tend to lag behind the front.

While details remain uncertain, strong to potentially severe storms may develop near/north of the surface low across parts of the Dakotas/MN, and also along the trailing cold front into the central Plains.

D5/Monday - D8/Thursday

The upper ridge across the Southeast is expected to remain in place through at least early next week, with some guidance suggesting potential for deamplification by the middle of the week. Multiple shortwaves may emerge from the persistent (though weakening) western trough through at least Wednesday, resulting in some potential for strong to severe storms along the periphery of the upper ridge from the Plains into the upper Midwest and Great Lakes, and possibly parts of the Northeast. However, predictability remains quite low regarding the details of any organized severe threats during this time frame.
