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:

Predictability Too Low: This means that severe storms might be possible, but forecasters aren't confident enough about where or when they might occur. Think of it as the models showing different possibilities, like pieces of a puzzle that haven't come together yet.
Potential Too Low: This means forecasters are fairly confident that widespread severe weather is NOT expected on that day. While isolated storms might still occur, the chance of reaching severe criteria across any given area is very low.

DISCUSSION

Primary feature of interest will be a shortwave trough over MT at 12Z Sunday and its major amplification into a broad eastern CONUS/southeast Canadian trough through mid-week. Poleward moisture quality from the western Gulf will remain sub-optimal, but will improve through D5/Monday. The northeast extent of weak surface buoyancy should reach the OH Valley by Monday afternoon, where guidance has been trending farther south with an intense mid-level jet. Given a prior EML and the deep surface cyclone tracking over Lake Superior to central ON vicinity, convective coverage may be limited along the trailing cold front. Still, consensus of guidance suggests that some fast-moving convection should accompany the portion of the front in the OH Valley vicinity. Robust 700-500 mb wind profiles should offer at least a threat for damaging winds.

Depending upon timing of frontal passage, a limited-area severe threat may exist on D6/Tuesday along the Southeast Atlantic coast. A compact southern-stream shortwave impulse, approaching the backside of the broad east CONUS trough, indicates low-probability severe potential over the southern Great Plains on D7/Wednesday into the western Gulf Coast vicinity D8/Thursday.
