The severe weather threat for Severe Thunderstorm Watch 518
SUMMARY...Severe risk -- mainly in the form of gusty winds --
continues locally within WW 518.
DISCUSSION...Latest radar loop shows a somewhat broken line of
storms along the advancing cold front, with gradual decreases in
intensity noted over the past hour. With surface analyses showing a
gradually cooling boundary layer, and afternoon special RAOBs
showing that cooling to have a very deleterious effect on available
CAPE, expect the decreasing trend in updraft intensity to continue.
While a locally damaging gust will be possible with a few stronger
elements within the convective band over the next 1-2 hours, risk
should gradually diminish -- and appreciable risk is not expected to
extend east of the current WW.
