Area Forecast Discussion
National Weather Service Houston/Galveston TX
1124 PM CDT Fri Mar 24 2017

.UPDATE...
Pulled back the Tornado Watch to just include the more eastern
counties of Fort Bend...Harris...Liberty...Montgomery...San
Jacinto...Polk...Trinity...and Houston Counties. Storms moving
east through Fort Bend...Harris...Liberty...and Polk Counties have
weakened enough to allow Severe Thunderstorm Warnings to expire
and leave up Special Weather Statements in their wake. These
storms are expected to move to the east of the forecast area
through the hour of Midnight. A thin line of convection forming
along the main front (currently positioned roughly along a Ft.
Worth to Stephenville to Lampasas line) is expected to travel
across the CWA between 10 and 15Z Saturday morning. The front
itself should just clear the coast through late morning...backing
cooler air mass remaining well off to the northeast providing
little to no cold air advection. A very shallow cooler and drier
late morning near surface air mass will quickly mix out and warm
into the middle to upper 70s (from minT upper 50s north to low 70s
along coast) in the early afternoon. Partially cloudy morning
skies with possible near coastal thunderstorms to clear out to
areawide sky clear by mid afternoon. Clear skies will prevail
through Sunday as the bulk of the direst air descends into the
region late tomorrow night. After a warm and dry late Saturday
around 80 F....evening will quickly cool off with a dying north
breeze...Sunday morning upper 50s to lower 60s min Ts. Sunny
Sunday with the afternoon warming into the average middle 80s
within dry regional air. 31
