Temperatures are in the lower 40s over all the plains with very weak surface winds in place. Models have zonal flow aloft today with an upper trough developing just upstream of the CWA. The main thing is the moisture and the energy from the upper trough.
Should see an increase in isolated/scattered convection over the region over the region well ahead of an approaching cold front/associated upper level trough. An upper trough is expected to dive southeast out of the Pacific Northwest and quickly strengthen as it moves into the Southern Plains on Wednesday. An isolated tornado threat will be a possibility especially along the warm front, which could act to locally enhanced low level shear profiles. A linear complex is expected to develop along the cold front Wednesday afternoon and evening.
