Area Forecast Discussion...UPDATED
National Weather Service Brownsville TX
1244 PM CDT Mon Aug 21 2017

.DISCUSSION...Made a few cosmetic changes to some of today`s
parameters, mainly sky cover and Gulf waves. As the eclipse
reaches peak (50 percent partiality) by 115 PM, the updated
forecast on clouds is working out nicely, as sea breeze has slid
inland and the beach is clear for those who have the ability to
use special glasses/tools to view. Thicker and in some cases
towering cumulus are edging along/just west of US 77/IH 69C in
time for the peak which may blot out the sun for some, and some of
the thicker clouds may reach the mid Valley in spots. Lesser sky
cover should hold across the upper Valley and Rio Grande Plains.

Otherwise...just enough moisture to kick off isolated showers and
perhaps a thunderstorm through 3 or 5 PM mainly in the Lower and
Mid Valley, with a sunny day on the beach as diurnal stability
trends are underway.
52/BSG

.AVIATION...Same stuff different day. Though isolated showers are
forming up just before 1 PM along the sea breeze, they`re
struggling to last and with sea breeze about to cross
Harlingen/Valley don`t think we`ll be able to see mentionable rain
there (it just passed Brownsville/South Padre Island Airport
around 1230 PM). Still expecting the dry air to overwhelm what`s
left of the sea breeze push into McAllen. Otherwise, raising
Scattered clouds as currently forecast with gusty east winds
through the afternoon followed by rapid clearing and nearly calm
winds by mid evening east and soon after midnight west. With
moisture similar or perhaps a bit lower Tuesday morning, kept only
Scattered low VFR conditions with light winds.
