area forecast discussion
national weather service houston galveston tx
321 pm cdt Sat aug 24 2019

Short term
Short term and global models have done a poor job initializing
conditions today and showers and thunderstorms have been slow to
develop. Convective temperatures are in the middle 80's and this
threshold has been met. Upper level winds are also broadly
divergent so am a little perplexed as to why convection has not
developed. Think the texas tech WRF has initialized the best and
this model suggests that there will be development in the next
hour or so. Will maintain chance pops inland for this evening.

Shra tsra over the gulf will continue overnight and this should
impinge on the coast and will carry likely pops along the
immediate coast. Weak low pressure over the gulf has remained
disorganized and whatever is left of the low will likely get
gobbled up by a trough over the central plains ms delta on Sunday.

Pw values on Sunday remain between 1.90 and 2.25 inches.

Convective temperatures are in the lower 90's which looks
reachable so am expecting shra tsra to develop with heating. Upper
level winds still look favorable on Sunday before subsidence
kicks in Sunday night and Monday. 43

Long term
The upper level trough over the central us will shift east Sunday
night and upper level ridging over the western us will move back
into the area. Subsidence associated with the upper ridge will
bring drier conditions and much warmer temperatures through mid
week. The ridge breaks down a bit and retreats west Thu fri. A
weak front will slide into east texas on Thursday but pressure
rises behind the front don't look too impressive so it is unclear
if the front will make it all the way across SE tx or stall across
the area. The front will bring a renewed chance of precip wed
night into Friday. 850 mb temps cool a bit so would expect
slightly cooler daytime highs Thu fri. 43

Marine
High moisture within a continued unsettled maritime environment will
likely allow for the redevelopment of late Saturday through early
Sunday scattered showers and thunderstorms. High pressure over the
northern gulf will maintain a generally weak onshore wind field
through Sunday afternoon. A slight deepening of texas panhandle
pressure will create a tight enough onshore pressure gradient to
produce more moderate early work week southerlies. Caution level
winds are forecast late tomorrow through Monday morning. Overnight
Tuesday morning winds may also perk back up to around caution
criteria mainly due to the localized mix down of slightly stronger
mid level winds. Early week average sea heights will gradually pick
up by another foot or so, to 3 to 4 feet, but then fall back to
around 2 to 3 feet mid to late week. Mid to late week high pressure
at all levels will maintain weak onshore winds and low seas. 31

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
