Area Forecast Discussion
National Weather Service Houston/Galveston TX
332 PM CDT Thu Oct 11 2018

High temperatures so far today (as of 3 PM) are ranging from 
the upper 70s to the lower 80s with high pressure in control. 
Dew points in the mid 50s to lower 60s are helping to keep 
humidity levels on the low side with most spots around 45%. 
North to northeast winds in place today will become east to 
southeast tomorrow as the high moves off to the east resulting 
in warming temperatures and increasing humidities as we close 
out the week and head on into the weekend. While the rains 
associated with the remnants of Tropical Storm Sergio (currently 
off the Baja California peninsula) are expected to remain to the 
west of our area, we could have enough moisture in place for 
some activity to develop on Saturday. Increasing chances will 
come beginning on Sunday (mainly up north) and on into Sunday 
night and Monday (area wide) with the approach and slow passage 
of a strong cold front. Lots of clouds, much cooler temperatures,
breezy north to northeast winds (especially near and off the 
coast) and periods of rain can be expected behind the front for 
probably the first half of next week and maybe for the entire 
week as the flow aloft remains out of the southwest.  42 

Michael's swells are slowly subsiding as long period swell at the 
nearshore buoy has come down from from yesterday's 7 feet / 16 
second swell to current 4 feet / 5 second swell. Elevated water 
levels will keep the threat for the coastal flooding of Gulf-facing 
beaches and lower lying areas alive through the weekend. Weakening 
veering winds will remain under Caution levels through the evening 
and early Friday morning hours....both near and offshore seas 
falling to 2 feet by tomorrow afternoon. Lowering seas and offshore 
winds will lower the threat for rip currents. High pressure moving 
east will veer winds more south late tomorrow. Southeast winds will 
then strengthen to around 15 to 20 knots by late Saturday. Caution 
flags may be needed as winds and subsequently higher seas will 
increase the rip current and continued coastal flooding threat 
during weekend high tide times. A cold frontal passage on Monday 
will spike offshore winds Monday night into Tuesday. 31
