    ...Synopsis...
    Widespread elevated fire weather conditions are likely this
    afternoon across portions of the Great Basin, northern Sierra, and
    northern Rockies. This activity will largely be driven by
    strengthening mid and upper-level flow across the West as an upper
    trough shifts into the Pacific Northwest. A modest surge of moisture
    into the southern Great Basin will introduce the potential for
    scattered showers and thunderstorms for southern NV. 
    
    ...northern Sierra...
    The approach of the upper-level wave into the Pacific Northwest will
    induce broad surface pressure falls across eastern WA/OR and
    northwest NV. In response, west to southwesterly winds will increase
    to around 15 mph. Terrain influences will likely result in stronger
    winds in the immediate lee of the Sierra. Downslope warming and
    drying will support RH reductions into the teens, and possibly upper
    single digits. While elevated conditions are likely, modest fuel
    readiness will yield an overall modest fire weather threat. 
    
    ...Great Basin to southern Wyoming...
    A weak upper-level wave noted in morning water-vapor imagery will
    shift into the southern Great Basin through the day. Strengthening
    southerly downslope flow will result in breezy conditions across
    southern NV. Winds between 15-20 mph will likely coincide with RH
    reductions into the 10-15% range during the early afternoon hours.
    Elevated conditions appear probable, and a few locations in southern
    NV may see transient critical conditions. Increasing
    rain/thunderstorm chances during the late afternoon and evening
    hours may limit the duration of the threat and aid in RH recoveries.
    Further to the northeast, more localized elevated conditions are
    expected across UT and southwest WY, but may linger well into the
    late afternoon hours. 
    
    ...northern Rockies...
    Lee troughing in the lee of the Canadian Rockies juxtaposed next to
    a surface high over the northern Plains will support strengthening
    southerly winds across the northern Rockies. Sustained winds between
    15-20 mph are likely with gusts up to 25-30 mph possible. An
    unseasonably dry air mass over MT coupled with some downslope
    influences will yield RH values in the single digits to low teens,
    supporting elevated to locally critical fire weather conditions. The
    highest potential for critical conditions will reside across
    northeast ID into adjacent areas of MT where fuels are near the 97th
    percentile, RH values below 10% are likely, and terrain influences
    will support pockets of 20+ mph winds. However, confidence in the
    coverage and duration of these conditions remains too low for a
    critical area.

    Concerning...Severe potential...Watch possible 
    
    Valid 170553Z - 170700Z
    
    Probability of Watch Issuance...40 percent
    
    SUMMARY...Strong to locally severe gusts are possible as a squall
    line moves east across southern MN.
    
    DISCUSSION...Latest surface mesoanalysis places a pre-frontal
    boundary oriented from southwest MN northeastward into parts of
    central MN ahead of a squall line advancing east.  The surface wind
    shift will probably continue to serve as a focus area for the
    northern periphery of stronger outflow winds.  South of the
    boundary, surface temperatures are warmer with low-mid 70s observed.
    The Sioux Falls, SD 88D VAD showed a strong southwesterly LLJ this
    evening (50+ kt) beneath a weakness in flow evident in the hodograph
    in the 3-6 km AGL layer, surmounted by stronger flow above (50-65 kt
    in the 6-9 km layer).  This wind profile undoubtedly favors a squall
    line mode.  It appears the orientation of the squall line is at
    least marginally favorable with respect to the mean flow in the 1-6
    km layer.  So despite appreciable convective inhibition from a
    slow-to-cool boundary layer, the strength of the wind field may
    continue to enable localized severe gusts with the squall line.  A
    plethora of surface observations during the past hour seem support
    this notion (e.g., KFSD, KPQN, KBKX) with gusts ranging mainly in
    the 40-45 kt range.

    ...NO SEVERE THUNDERSTORM AREAS FORECAST...
    
    ...SUMMARY...
    The risk for severe thunderstorms currently appears negligible
    across the U.S. Saturday through Saturday night.
    
    ...Synopsis...
    Models indicate that generally zonal westerlies, across the northern
    mid-latitudes of the Pacific through North America, will undergo
    amplification through this period.  It appears that this will
    include large-scale mid-level troughing evolving across the
    northeastern Pacific into the northwestern U.S. and western Canada. 
    Within this regime, one significant short wave trough is forecast to
    accelerate inland across the British Columbia and Pacific Northwest
    coast, before continuing across the Canadian Rockies and Prairies
    accompanied by the development of a broad and deep surface cyclone. 
    To the south of this feature, deepening surface troughing appears
    likely through much of the higher U.S. Great Plains.  This may be
    accompanied by modest low-level moisture return on southerly flow,
    but this will occur beneath a narrow plume of warming and capping
    elevated mixed-layer air.
    
    An upstream short wave trough is forecast to dig into the U.S.
    Pacific Northwest by 12Z Sunday.  The leading edge of stronger
    mid-level cooling aloft (500 mb temps of -20 to -22C) associated
    with this feature may begin to spread inland across the Pacific
    Northwest coast Saturday afternoon into Saturday night.  It is
    possible that this could contribute to instability sufficient for a
    few weak thunderstorms, but probabilities generally appear near the
    minimum threshold for a categorical thunderstorm area.
    
    In response to the progression of the trailing perturbation, weak
    mid-level troughing emerging from the subtropical eastern Pacific
    likely will accelerate northeastward, inland of the southern
    California coast.  It may become increasingly sheared as it does,
    but low/mid-level moistening ahead of it may contribute to scattered
    thunderstorm activity Saturday across parts of the eastern Great
    Basin and Colorado Plateau into adjacent portions of the Rockies.
    
    Downstream of the building mid-level ridge, it appears that another
    significant short wave trough will rapidly progress across Quebec
    through Newfoundland and Labrador and portions of the Canadian
    Maritimes.  This will be accompanied by the southeastward
    progression of another cold front across the lower Great Lakes, much
    of the Northeast and Mid Atlantic.  However, in the wake of a
    possible developing tropical cyclone east of the north Atlantic
    coast, it appears that the environment will generally only become
    conducive to widely scattered, weak thunderstorm activity.
    
    Seasonably high moisture content is expected to remain confined to a
    plume shunted off the northern and middle Atlantic coast, in the
    wake of the tropical perturbation, but still trailing southwestward
    and westward, inland across much of the Southeast, ahead of weak
    mid-level troughing over the lower Mississippi Valley/northwestern
    Gulf Coast.  This may contribute to fairly numerous, but generally
    weak, thunderstorm activity with daytime heating Saturday.

    Valid 171200Z - 181200Z
    
    ...NO SEVERE THUNDERSTORM AREAS FORECAST...
    
    ...SUMMARY...
    Severe thunderstorms appear unlikely across the contiguous United
    States today. However, a few strong storms are possible across parts
    of west Texas, and southern Arizona during the late afternoon.
    
    ...Great Lakes into the central Plains and into west TX...
    A fast-moving and deep upper trough will move from the northern
    Plains/Upper MS Valley across the Great Lakes through 00Z, lifting
    east/northeast into Quebec overnight. At the surface, a cold front
    will extend roughly from Lake Michigan into central KS and the TX
    Panhandle by 21Z, with 60s F dewpoints ahead of it.
    
    The strongest lift the upper trough will quickly depart the Upper
    MI/Lake Superior region, leaving behind weakening convergence along
    the boundary. Still, heating and sufficient moisture, as well as
    residual cool air aloft will likely yield regenerating storms along
    the front, from IL/WI southwestward into KS and western OK. Shear
    will be weak in these areas, with only short-lived updrafts likely.
    
    Other storms are expected to form during the peak heating hours from
    the TX Panhandle into the South Plains. Here, lapse rates will be
    steep below 500 mb, and could result in locally strong wind gusts.
    Most CAMs show storms initiating across the eastern TX Panhandle,
    propagating south/southwestward.
    
    ...Far southern AZ...
    Gulf moisture will begin to return to the border region of southern
    Arizona, possibly contributing to 500-1000 J/kg MLCAPE by late
    afternoon. Heating will result in inverted-V profiles, and a few
    storms may develop in this regime by late afternoon or early
    evening. Isolated, strong convective gusts cannot be ruled out, but
    being diurnally driven in a weak shear environment, any severe wind
    risk appears limited in magnitude, space and time.

    Severe Thunderstorm Watch Number 506
    NWS Storm Prediction Center Norman OK
    815 PM CDT Thu Sep 16 2021
    
    The NWS Storm Prediction Center has issued a
    
    * Severe Thunderstorm Watch for portions of 
      Central and western Nebraska
      Southern South Dakota
    
    * Effective this Thursday night and Friday morning from 815 PM
      until 300 AM CDT.
    
    * Primary threats include...
      Scattered large hail and isolated very large hail events to 2
        inches in diameter possible
      Scattered damaging wind gusts to 70 mph possible
    
    SUMMARY...Growing clusters of thunderstorms on either side of a
    slow-moving cold front should pose a severe hail/wind threat, as
    they access a strengthening low-level jet, and move east-
    northeastward across the watch area tonight.
    
    The severe thunderstorm watch area is approximately along and 90
    statute miles north and south of a line from 30 miles south
    southwest of Mullen NE to 30 miles northeast of Oneill NE. For a
    complete depiction of the watch see the associated watch outline
    update (WOUS64 KWNS WOU6).
    
    PRECAUTIONARY/PREPAREDNESS ACTIONS...
    
    REMEMBER...A Severe Thunderstorm Watch means conditions are
    favorable for severe thunderstorms in and close to the watch area.
    Persons in these areas should be on the lookout for threatening
    weather conditions and listen for later statements and possible
    warnings. Severe thunderstorms can and occasionally do produce
    tornadoes.
    
    &&
    
    OTHER WATCH INFORMATION...CONTINUE...WW 504...WW 505...
    
    AVIATION...A few severe thunderstorms with hail surface and aloft to
    2 inches. Extreme turbulence and surface wind gusts to 60 knots. A
    few cumulonimbi with maximum tops to 550. Mean storm motion vector
