Valid 011200Z - 021200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe potential appears low on Tuesday.

....Discussion...

An upper ridge will remain centered over the High Plains vicinity on
Tuesday, with a mean upper trough persisting over the Atlantic Coast
states. A weak upper shortwave trough will migrate across western
Canada, modestly suppressing the upper ridge near the international
border over MT. Most guidance keeps any stronger forcing and
southwesterly deep-layer flow north across Alberta/Saskatchewan.
Modest mid/upper northwesterly flow will persist across parts of the
Midwest, but large-scale ascent will remain nebulous. While isolated
thunderstorms are possible in a seasonally moist/unstable and
modestly sheared environment from parts of the northern/central
Plains into the Mid/Lower MO Valley, severe potential appears too
low/uncertain to include probabilities at this time.
