...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms will be possible today from the southern Plains into
the Arklatex and Ozarks. No severe threat is expected.
...DISCUSSION...
The upper-level pattern across the continental United States today
has a trough near the coast of New England, with another deepening
system in the Four Corners region. This trough will become more
amplified as it approaches the southern and central Rockies late
this afternoon. Ahead of the trough, southwest flow will enable
southerly flow to strengthen from the southern Plains into the lower
Missouri Valley. Elevated thunderstorm development will be possible
this afternoon and evening along and near the axis of a 40 to 50
knot low-level jet, oriented north-northeastward across central
Texas and east-central Oklahoma. Instability along this corridor
will remain weak, suggesting a severe threat will be unlikely today.
Elsewhere across the continental United States, thunderstorms are
not expected today or tonight.
