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

Wednesday/Day 4 to Thursday/Day 5

On Wednesday, model forecasts continue to move a mid-level shortwave trough across the southern Plains. A cold front is forecast to advance southeastward into Oklahoma as a moist and unstable airmass resides southward from the front over much of the southern Plains. Surface dewpoints across southeast Oklahoma and north-central to northeast Texas should be in the lower to mid 60s F, and moderate instability will be possible by afternoon. Thunderstorm development appears likely across parts of this unstable airmass from the mid afternoon into the evening. Moderate deep-layer shear should support a severe threat, with a potential for large hail and damaging wind gusts associated with supercells.

On Thursday, the shortwave trough is forecast to move into the mid Mississippi Valley, as a much larger upper-level trough moves through the Desert Southwest. A moist and unstable airmass should remain in place over the southern Plains. However, large-scale ascent should be weak between these two systems, which should dampen the severe potential across most of the south-central U.S. The most likely location for an isolated to marginal severe threat would be in the Ark-La-Tex Thursday afternoon.

Friday/Day 6 to Sunday/Day 8

At mid-levels, southwest flow is forecast across much of the central U.S. on Friday, as a large trough remains over the southwestern states. Moisture advection is expected to continue over the Great Plains and Upper Midwest along a corridor of strong low-level flow. Model forecasts are in general agreement that moderate instability will develop over much of this airmass by Friday afternoon, and that scattered thunderstorms will form. Convective development will be supported by the right entrance region of a mid-level jet ejecting northeastward through the central Plains. This mid-level jet will be associated with moderate to strong deep-layer shear, supporting scattered severe storms potentially across a large part of the moist sector. The current thinking is that the severe threat will be maximized during the late afternoon and evening from central Texas northeastward into the lower Missouri Valley. Large hail and damaging wind gusts are expected to the primary threats, but a few tornadoes remain possible.

On Saturday, the upper-level system in the central U.S. is forecast to move into the Great Lakes region, as a cold front advances quickly southeastward into the western Gulf Coast states, and lower Mississippi Valley. An isolated severe threat could develop ahead of the front Saturday afternoon, but confidence is low concerning the spatial distribution of any threat. On Sunday, isolated to scattered thunderstorms will again be possible in the Gulf Coast region. However, deep-layer shear is forecast to be weak over much of this area, suggesting any severe potential should remain marginal.
