...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
KANSAS...

...SUMMARY...
Isolated severe thunderstorms may develop across western and central
Kansas late this afternoon and early evening, with hail and locally
severe wind gusts possible.

...Western/central Kansas...
The region will be glancingly influenced by an eastward-progressing
upper trough over the northern Plains. Ample insolation and robust
heating of a boundary layer, characterized by limited moisture (40s
F dewpoints), will result in convective temperatures being reached
by peak heating near a southeastward-moving front. Isolated to
widely scattered convective initiation is expected around or after
20Z, when 30+ F T/Td spreads will be in place. High-based multicells
will be the likely storm mode, as strong northwesterly flow aloft
will contribute to elongated, straight hodographs. The strongest
storms may produce hail and severe wind gusts on an isolated basis.

...Southern Florida...
A couple of stronger storms with gusty winds could again occur
today, mainly across the southeast part of the Florida Peninsula
this afternoon. Any severe threat should remain relatively marginal
and localized given the overall setup and thermodynamic environment.

...DISCUSSION...
...Saturday/Day 4 to Monday/Day 6...
On Saturday, mid-level southwesterly flow will strengthen over the
central U.S., as an upper-level system moves to near the West Coast.
A moist airmass will be in place over the southern and central
Plains, as a low-amplitude shortwave trough moves across the region.
Large-scale ascent along with warming surface temperatures will
result in scattered thunderstorm development over much of west Texas
Saturday afternoon. MLCAPE is expected to peak near 1000 J/kg in
some areas, with 0-6 km shear being in the 30 to 40 knot range over
much of the southern High Plains. This should be sufficient for a
severe threat, with large hail and severe wind gusts possible.

From Saturday night into Sunday, strong moisture advection is
forecast over the Great Plains. By Sunday afternoon, moderate
instability is expected to be in place over much of this airmass.
Isolated to scattered severe thunderstorms are expected throughout
much of the moist sector during the afternoon and evening. Some
model forecasts move a 50 to 60 knot mid-level jet through central
and northeast Texas during the afternoon and evening. If this
happens, then a substantial severe threat would be possible from
parts of central and north Texas into Oklahoma. Severe storms,
including supercells with large hail, wind damage and a tornado
threat would be possible in areas that destabilize the most.

On Monday, a moist and unstable airmass is forecast to remain from
the southern Plains extending north-northeastward into the Upper
Midwest. Strong to severe thunderstorm development will be possible
over much of the instability corridor in the afternoon and evening.
The greatest potential for severe storms is forecast from the
southern Plains north-northeastward into the lower Missouri Valley
and upper Mississippi Valley, where the models develop moderate
instability and have 0-6 km shear mostly in the 30 to 40 knot range.
Severe storms with large hail, wind damage and a tornado threat will
be possible.

...Tuesday/Day 7 and Wednesday/Day 8...
The western U.S. trough is finally forecast to approach the southern
Plains on Tuesday, where a moist and unstable airmass should be in
place. Some solutions suggest that a mid-level jet will move into
the southern Plains Tuesday afternoon. This would create strong
deep-layer shear over parts of the moist sector, suggesting that a
substantial severe threat will be possible. Although there is still
spatial uncertainty regarding this scenario, current model forecasts
would support supercells with large hail, severe wind gusts and some
tornadoes.

On Wednesday, a shortwave trough is forecast to move through the
central states, with a southwest-to-northeast corridor of moderate
instability in place by afternoon from northeast Texas into western
Ozarks. This would be favorable for severe storms. However, at this
extended range, considerable uncertainty exists concerning severe
threat magnitude and spacing.
