...DISCUSSION...
In general, the latest medium-range model output suggests that the
prevailing split flow will continue to evolve in a manner that
results in a broadly confluent regime developing across and east of
the Rockies by mid week through next weekend. Within the northern
branch, it appears that a mid-level low will develop and deepen
within broad troughing overspreading the Northeast, while an
initially prominent subtropical high, centered over southern Mexico,
becomes suppressed, as the first in a series of developing southern
stream lows is forced inland across the southern tier of the United
States. It appears that this will be preceded by broad cool surface
ridging overspreading much of the central and eastern U.S., as far
south as the Gulf Coast region by Thursday. While associated
forcing for ascent and destabilization might support increasing
thunderstorm development across parts of central and southern Texas
late this work week, mostly above/to the cool side of a stalling
frontal zone, into Florida and adjacent portions of the Southeast by
late next weekend, the risk for severe weather appears relatively
minor at this time.
