    ...NO SEVERE THUNDERSTORM AREAS FORECAST...

    ...SUMMARY...
    Isolated to scattered thunderstorms are expected today across the
    Florida Peninsula, and portions of the Four Corners, northern
    Rockies, and eastern Great Lakes. While a few strong storms may
    occur across the central/southern Florida Peninsula, organized
    severe potential is expected to remain low.

    ...Synopsis...
    The East will remain influenced by longwave troughing, while
    westerly quasi-zonal upper flow prevails elsewhere. Much of the
    northern, central, and eastern CONUS will be dominated by surface
    high pressure while surface lee troughing, with dry low-level
    trajectories, takes place over the southern High Plains.
    Thunderstorms are expected mainly this afternoon across the Florida
    Peninsula. A few embedded mid-level impulses, accompanied by cooler temperatures aloft, will foster enough lift amid scant buoyancy to
    encourage a few lightning flashes across the northern Rockies, Four
    Corners region, and the eastern Great Lakes today.

    ...Central/southern Florida Peninsula...

    Ample insolation/heating should occur today along and south of the slow-southward progressing front. This heating combined with
    easterly low-level winds should focus convergence and scattered
    thunderstorm development this afternoon across the interior
    peninsula. With the upstream shortwave trough not influencing the
    region until later tonight, mid-level lapse rates will remain
    relatively poor with weak deep-layer shear. Regardless, steepening
    low-level lapse rates should lead to increasing storm coverage and
    intensity this afternoon, particularly across the interior, and a
    few of these pulse-type storms could produce strong
    downburst-related gusty winds. However, it currently appears that severe-caliber wind gust potential will remain limited given the
    marginality of the overall scenario.
