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

Days 4-5/Tue-Wed

An active pattern with severe thunderstorm potential is expected Tuesday and Wednesday from the southern Plains to the Mid/Lower MS and OH Valleys. Medium range guidance is in fairly good agreement during this time. Starting on Tuesday, an upper low over northern Mexico will shift east/northeast, becoming an open wave as it begins to merge with a northern stream upper trough developing southeast across the northern/central Plains through early Wednesday. A belt of strong southwesterly deep-layer flow will overspread a large warm sector on Tuesday. Lee cyclogenesis is forecast across the central/southern High Plains, along with a second surface low developing over IA as the northern stream upper trough approaches. This setup will allow for a sharpening dryline/Pacific front across the southern Plains, while a cold front develops southeast into the MO/Mid-MS Valley overnight. Strong ascent should focus thunderstorm development across the warm sector ahead of these surface boundaries within a strongly sheared environment, and potentially widespread severe thunderstorm activity is possible.

The large-scale upper trough and attendant surface cold front will continue to progress eastward on Wednesday. Uncertainty does increase, especially with north and east extent of severe potential. How far east convection develops on Tuesday and how much downstream destabilization occurs is somewhat unclear. Nevertheless, a deepening surface cyclone is forecast to develop northeast from the Great Lakes into Ontario and Quebec, while strong deep layer southwesterly flow overspreads a moist warm sector ahead of the surface front. This should set the stage for at least isolated to scattered severe thunderstorm potential along the length of the cold front through Wednesday evening.

Given uncertainties mentioned above, these areas are likely to be adjusted in coming days as details become better resolved, but the overall pattern should support a couple of active severe weather days over a broad area.

Day 6/Thu

Uncertainty increases by Thursday as spread among medium range guidance increases quite a bit with respect to the evolution/timing of the upper trough. Some severe potential could persist/develop across the Mid-Atlantic region, but predictability is too low to include a 15 percent delineation at this time.

Beyond Thursday, severe thunderstorm potential will likely be low as the upper pattern become lower amplitude and stronger westerly flow remains confined to the northern tier of the U.S., along with Gulf moisture largely remaining offshore behind the cold frontal passage.
