Severe line of storms continues to race east across east central Kansas.
On the southern end of the line, the outflow has surged well ahead of the line into north-central Oklahoma. This may set off some new showers or isolated storms across far northeast Oklahoma this morning, so will keep some low pops in for the first part of the forecast. Otherwise, this Memorial Day should remain thankfully dry, and this will be the first dry day of the past few for northeast Oklahoma.
The chance for showers and severe storms returns for Tuesday, although the main threat may hold off until the late afternoon and evening. Upper low near the four corners will move northeast across northern Colorado as a surface low-pressure system moves into Kansas.
A cold front will be positioned across central Kansas by late Tuesday afternoon, with a warm and unstable airmass across much of central and eastern Oklahoma. Deep layer shear will support supercells forming in the afternoon, with all severe hazards possible.
The strengthening of the low-level jet by evening into the overnight hours may increase the tornado potential
Any additional rain is unwelcome at this point, given the ongoing widespread flooding. The potential for heavy rain is greater on Wednesday as the front makes its way across eastern Oklahoma and western Arkansas.
