Area Forecast Discussion
National Weather Service Houston/Galveston TX
415 AM CDT Fri Jul 21 2017

.DISCUSSION...
Early morning temperatures (4 AM) range from the mid to upper 70s inland
to the lower 80s at the coast. Look for another warm July day with high
temperatures around 90 at the coast and in the mid/upper 90s inland
with heat index values generally in a 102-107 range. The area remains
on the southern fringes of mid/upper level ridging, and water vapor
satellite images show a westward moving mid/upper level Florida panhandle
low that will bring our area its next best chance of storms. Before
this feature`s influence arrives over the weekend, look for one more
day with isolated to widely scattered showers and thunderstorms - near
the coast in the morning and developing inland as the day progresses.
Rising rain chances can be expected over the weekend as moisture and
instability increases with the arrival of the mid/upper level low.
Slightly lower afternoon high temperatures are anticipated over the
weekend due to the increasing clouds and rain chances. Ridging tries
to build back across the area next week, and this should help to lower
rain chances and raise temperatures similar to what we have seen over
the last couple of days.  42

.MARINE...
Weak disturbances...along with the weekend visit of a weak low
currently rotating west out of Florida...will introduce periodic
showers and thunderstorms. Early day light southwesterlies will veer
more southerly through the day. A tighter onshore gradient by early
Sunday through the early work week will strengthen overnight winds
to near Caution levels. Wave heights will pick up from their current
1 to 2 foot heights to nearshore 2 feet to 4 feet offshore average
heights by Monday. 31

.CLIMATE...
Houston/Hobby Airport set a new record high minimum temperature yesterday
when the low only got down to 80 degrees (old record was 79 degrees
set in 1980). Earlier this month, Hobby tied two record high minimum
temperatures (80 degrees on the 13th and 79 degrees on the 14th). 42
