    Areas affected...central into northern VA...MD...far southeast PA

    Concerning...Severe Thunderstorm Watch 436...

    Valid 132048Z - 132215Z

    The severe weather threat for Severe Thunderstorm Watch 436
    continues.

    SUMMARY...Severe gusts are possible and perhaps becoming maximized
    in coverage over the next 1-2 hours from 30 mi north of Richmond
    northward through D.C./BWI and through the upper Chesapeake Bay
    vicinity.

    DISCUSSION...Radar mosaic shows several strong to severe
    thunderstorm clusters from 35 mi north-northwest of Richmond and
    northward into southeast PA as of 445pm. The Warrenton-Fauquier
    (KHWY) ASOS recently observed a measured 56-kt gust at 435pm. This
    activity is moving east into the I-95 corridor during the next 1-2
    hours. With surface temperatures in the low-mid 90s with low-mid
    70s dewpoints, the stronger water-loaded cores will be capable of
    damaging microbursts and gusts in the 50-70 mph range.
