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

Medium-range model output indicates generally low predictability concerning the evolution of the blocking pattern over the mid-latitude central into eastern Pacific, and downstream developments inland and across North America, through this period. Most certain, at this time, it appears that a fairly significant perturbation emerging from Intermountain West on Tuesday will be accompanied by deep surface troughing overspreading much of the mid/lower Missouri Valley through the Upper Midwest and Ohio Valley, before weakening across the Great Lakes on Wednesday. This will be accompanied by strengthening deep-layer wind fields and shear, conditionally supportive of organized convective development given sufficient destabilization. However, there has been little change from prior model runs, which have indicated that, despite an initially seasonably warm environment across much of the Great Plains and Mississippi Valley, the lack of appreciable Gulf moisture return will inhibit convective potential through at least the middle of next week.

Thereafter, in the mean, a broadly cyclonic to anticyclonic southwesterly regime may characterize the flow into next weekend across the southern Rockies and Great Plains through the Mid Atlantic, to the west-northwest through north of a fairly prominent subtropical high shifting from the Gulf Basin into Bahamas/Caribbean vicinity. It is possible that a short wave embedded within this regime may support significant lee cyclogenesis, as the Gulf boundary layer becomes supportive of a more substantive moist return flow. This, in turn, could become supportive of an increase in potential for severe thunderstorm development, but a clear and consistent signal has yet to emerge in the various medium range guidance.
