Area Forecast Discussion

423 AM CDT SAT MAY 28 2016
Clouds continue to clear out of Southeast Texas early this morning as
yesterday`s MCS moves off to the east. Some low clouds and fog (some
dense) will have a chance to develop across the area before sunrise.
Daytime heating could provide an opportunity for some shower/thunderstorm
development today, but think the majority of the area will stay dry
as upper level heights rise a little in response to ridging building
into the area from the south. If anything does develop during peak heating,
some model soundings indicate that they could become strong or severe.
But again, think the majority of us will be rain free. With wet grounds
and light winds, parts of Southeast Texas could see some fog development
again later tonight through early Sunday morning. Will continue to carry
low rain chances on Sunday as possible activity moves into the area
from the west and southwest. Look for a similar forecast (low rain chances)
for Memorial Day. It will be warm and muggy over the holiday weekend
with heat index values peaking in the afternoon in the mid to upper
90s. Better rain chances come back into the forecast beginning on Tuesday
as the holiday weekend ridging begins to break down and the next mid/upper
level trough organizes out west. This slow eastward moving system will
bring periods of showers and thunderstorms to the state with better
rain chances probably across our western/northern counties on Tuesday
and Wednesday working their way eastward for the rest of our area on
Thursday and maybe Friday. At this time, the end of next week and next
weekend are looking quiet as a developing eastern U.S. trough aloft
sets up a drier northwest flow across our area. 42
The western expansion of eastern U.S. high pressure will relax the
recently tight onshore pressure gradient. Responding southeasterlies
this weekend will remain in the 5 to 15 knot range with lowering
weekend seas back to average 3 to 4 foot heights...2 to 3 feet
Memorial Day...with a 6 second period. Weak disturbances moving up
from Mexico atop the slow expansion of southern Gulf upper ridging
will keep slight rain and storm chances around through Memorial Day.
Due to relatively lower onshore winds and less rough seas...rip
currents should not be overly strong. Obviously...rip currents will
still exist and swimmers are strongly discouraged to swim near groins...
jetties or within passes. Always swim with a buddy and near a lifeguard.
