and expand in coverage by early evening. Severe weather is
expected into northeast Oklahoma by early evening and steadily
spreading eastward through the early morning hours Tuesday.
Conditions will support significant severe weather especially

likely especially during the evening hours including the risk
for strong long track tornadoes. Additionally, large hail and

if storms do develop by early Wednesday morning. A more widespread
severe weather risk is expected from late Wednesday morning through
the afternoon as a cold front sweeps eastward. Locations south and

considered.
