    Day 3-8 Fire Weather Outlook  
    NWS Storm Prediction Center Norman OK
    0245 PM CST Wed Dec 13 2023
    
    Valid 151200Z - 211200Z
    
    Fire weather potential remains limited through the extended period.
    Long-range guidance shows reasonably good agreement in the eastward
    migration of the upper low currently over the lower CO River Valley
    into the Southeast over the next several days. This will bring
    widespread rain chances across the southern Plains into the Gulf
    Coast states where an unseasonably air mass is currently in place.
    An amplification of the upper trough building over the West Coast
    appears likely as it shifts east over the central CONUS later this
    week. This will favor weak gradient winds at the surface, further
    limiting fire weather potential. The southern California coast will
    continue to see a weak offshore flow regime through the weekend, but
    confidence in reaching critical wind/RH thresholds is low, and rain
    chances are forecast to increase heading into next week.
    Consequently, the emergence of fire weather concerns appears low
    through early next week.

    Valid 132000Z - 141200Z
    
    ...NO SEVERE THUNDERSTORM AREAS FORECAST...
    
    ...SUMMARY...
    Scattered, generally weak, thunderstorm activity remains possible
    late this afternoon through tonight across parts of the Four Corners
    and southern Rockies into the Texas South Plains and Panhandle
    vicinity.
    
    ...20Z Update...
    
    ...Florida...
    Cloud cover and rain across much of the southeastern Florida
    Peninsula and Keys have contributed to the maintenance of a
    generally stable boundary layer, with little forcing in lower-levels
    to support an appreciable risk for thunderstorms.  Some risk for
    convection capable of producing lightning may linger offshore of
    coastal areas, mainly along the surface front, to the east of the
    Greater Miami vicinity.

    .PREV DISCUSSION... /ISSUED 1017 AM CST Wed Dec 13 2023/
    
    ...Synopsis/Discussion...
    A closed mid/upper-level low will continue eastward over the Four
    Corners area and southern Rockies through tonight, removed from a
    more progressive belt of westerlies over the northern tier of the
    CONUS and Canada. Steepening lapse rates and ascent ahead of the
    aforementioned upper low will support isolated thunderstorm
    potential from northeast Arizona/southeast Utah into New Mexico
    especially tonight, while other thunderstorms will be possible today
    and tonight farther east across eastern New Mexico and western Texas
    within a persistent warm advection regime.
    
    Additionally, a few thunderstorms will be possible across/near south
    Florida near a convergence zone where a moist air mass persists.

    ...Synopsis...
    The cutoff low within the Four Corners will become an open wave and
    eject into the southern Plains on Thursday. High pressure at the
    surface is still expected to remain expansive. Cooler temperatures,
    light winds, and precipitation will again keep fire weather concerns
    at a minimum for most areas. Offshore flow will continue in southern
    California, but without greater upper-level wind support, concerns
    will remain localized.

  9. SPC 1730Z Day 2 Outlook
    Day 2 Outlook Image
    Day 2 Convective Outlook  
    NWS Storm Prediction Center Norman OK
    1055 AM CST Wed Dec 13 2023
    
    Valid 141200Z - 151200Z
    
    ...NO SEVERE THUNDERSTORM AREAS FORECAST...
    
    ...SUMMARY...
    The risk for severe thunderstorms appears negligible across the
    U.S., Thursday through Thursday night.
    
    ...Discussion...
    Seasonably high heights associated with general large-scale
    mid-level ridging appear likely to prevail across much of the U.S.
    and Canada through this period, with the most pronounced mid-level
    height anomalies shifting east-southeastward into the Great Lakes
    region, in the wake of at least a pair of short wave troughs
    progressing off the Atlantic Seaboard.  Within this regime, weak
    mid-level troughing is forecast to slowly progress east of the U.S.
    Rockies, with an embedded low migrating east-northeast/east of the
    southern Rockies through the Texas Panhandle or Texas South Plains
    vicinity by 12Z Friday.  
    
    There remains substantive spread among the various model output
    concerning the track of the mid-level low, but appreciable surface
    cyclogenesis across the southern Great Plains is unlikely with
    initially entrenched surface ridging slow to weaken.  Although
    models indicate that the more strongly supporting confluent
    mid-level flow will begin to shift east of the southern Atlantic
    Seaboard by early Thursday, expansive cold surface ridging (centered
    over the southern Appalachians) is forecast to generally be
    maintained across much of the Southeast and northern Gulf of Mexico
    into at least early Friday.
    
    Seasonably high moisture content likely will remain confined along
    and south of a remnant baroclinic zone, south of the Florida Straits
    into the southwestern Gulf of Mexico.  This front (particularly
    across portions of the south central Gulf) may become a focus for
    increasing thunderstorm development Thursday through Thursday night,
    aided by forcing associated with a mid/upper short wave perturbation
    emerging from the subtropical eastern Pacific.
    
    Otherwise, modest elevated moisture return, coupled with cooling
    further aloft associated with the mid-level low, probably will
    support continuing weak thunderstorm development across the southern
    Rockies into southern Great Plains vicinity into early Friday.

    Valid 131630Z - 141200Z
    
    ...NO SEVERE THUNDERSTORM AREAS FORECAST...
    
    ...SUMMARY...
    Isolated thunderstorms are possible through tonight from the Four
    Corners into west Texas, and across parts of south Florida. Severe
    storms are not expected.
    
    ...Synopsis/Discussion...
    A closed mid/upper-level low will continue eastward over the Four
    Corners area and southern Rockies through tonight, removed from a
    more progressive belt of westerlies over the northern tier of the
    CONUS and Canada. Steepening lapse rates and ascent ahead of the
    aforementioned upper low will support isolated thunderstorm
    potential from northeast Arizona/southeast Utah into New Mexico
    especially tonight, while other thunderstorms will be possible today
    and tonight farther east across eastern New Mexico and western Texas
    within a persistent warm advection regime.
    
    Additionally, a few thunderstorms will be possible across/near south
    Florida near a convergence zone where a moist air mass persists.

    ...NO CRITICAL AREAS...
    
    The previous forecast remains on track with no changes needed.
    Latest surface observations along the southern CA coast show winds
    gusting between 30-40 mph, but RH has generally remained above 30%.
    Some diurnal RH reduction is anticipated this afternoon, and may
    result in localized fire weather concerns (mainly over Ventura and
    LA counties). However, the potential for more widespread elevated
    conditions remains too limited for highlights.

    ...Synopsis...
    The CONUS will generally be under the influence of an upper-level
    ridge today. A cutoff low will slowly progress eastward toward the
    Four Corners, becoming more of an open wave in the process. At the
    surface, high pressure will be present across the vast majority of
    the CONUS. Cooler temperatures, light winds, and precipitation will
    keep fire weather concerns low for most areas. Some locally elevated
    fire weather may occur in southern California as modest offshore
    flow persists through the period.

    ...NO SEVERE THUNDERSTORM AREAS FORECAST...
    
    ...SUMMARY...
    A few thunderstorms will be possible through tonight from the Four
    Corners into west Texas, and across parts of south Florida. Severe
    storms are not expected.
    
    ...Synopsis...
    A closed midlevel low will move slowly eastward over northern AZ
    toward NM by Thursday morning.  Surface ridging and an associated
    cool air mass will be maintained across most of the central and
    eastern CONUS, beneath confluent midlevel flow.  This low-level flow
    regime will limit substantial boundary-layer moisture to south FL,
    where a few thunderstorms will be possible along the convergence
    zone coincident with the northwest edge of the 68-72 F dewpoints
    across the Keys and southeast FL.  Farther west, a modifying air
    mass with dewpoints in the low-mid 60s will persist across Deep
    South TX, though poor lapse rates aloft suggest that convection will
    remain too shallow for charge separation and lighting production.  
    
    Steepening midlevel lapse rates and ascent immediately east of the
    midlevel low could support isolated thunderstorms over the higher
    terrain of northeast AZ and western NM this evening into tonight.  A
    few lightning flashes with elevated convection will also be possible
    farther east in the persistent warm advection zone with weak
    buoyancy over west TX and the TX Panhandle.
