Areas affected...TX Coastal Plain

Concerning...Heavy snow

Valid 080738Z - 081045Z

SUMMARY...Isolated pockets of moderate snowfall (i.e. rates briefly
approaching 1" per hour) possible during the next 2 to 3 hours.

DISCUSSION...Current observations reveal wet-bulb effects have
reduced temperatures from around 34-36 degrees F to closer to
freezing across much of the region. This reduction in temperatures
has resulted in a change-over from light rain to light/moderate snow
across the region, evidenced by recent surface observations
reporting snow from CRP northeastward as far north as BMT.
Frontogenetic forcing responsible for these bands of snow will
persist, while gradually weakening, for the next several hours as it
slowly shifts eastward in response to the progression of the
mid-level trough. As such, potential for light to moderate snow is
expected to continue across the region for the next 2 to 3 hours.
