What's New / NOTES
10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome.
10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name.

Short term
Today and tonight
in the wake of Tuesday's rain event, a pacific front scoured out
the boundary layer moisture, clearing the skies. This effectively
eliminated our semi-permanent springtime moisture discontinuity,
known in these parts as the dryline. But as we find ourselves in
the latter stages of the spring season, we knew the dry air was
not going to stick around. Rich gulf moisture remained across the
coastal plains, and the return of southerly winds has allowed it
to make a rapid return to north and central texas. The 60-degree
isodrosotherm reached the metroplex during the predawn hours, and
dew points north of 70f have already invaded our southeastern
zones. Much more vigorous advection is occurring above the
nocturnal boundary layer where VWP data is estimating 50kts at
2-4kft agl. As a result, low clouds will continue developing and
spreading further inland through daybreak. Despite the intensity
of the advection, the thin layer is unlikely to produce any
sprinkles or drizzle, and the momentum within the surface layer
should preclude any fog. However, some brief reductions in
visibility will be possible in central and east texas during the
diurnal minimum of wind speed (predawn hours through sunrise).

The surging mt air will meet the seasonal ct air of west texas,
re-establishing and steadily sharpening the dryline on the high
terrain to our west. A healthy inversion above the cloud layer
will slow its erosion east of the boundary, but breaks of Sun will
gradually become more numerous into the afternoon hours. Although
it's only may 22, our Sun angle today will be the same as on july
20 or 21. Beyond the need for sunscreen, this emphasizes the power
of the insolation this time of year; and even with the extensive
cloud cover and moisture-laden surface layer, temperatures should
still manage to exceed seasonal normals this afternoon. Mlcape
values will soar above 4000 j kg, but with the surface boundary
well to our west and no large-scale forcing for ascent, this
instability will likely go unrealized. Toward peak heating, the
convergence along the dryline may allow for a few cells to develop
near or within our northwestern zones, but these should remain
isolated and would have a tendency to race north across the red
river, limiting their duration within north texas. Regardless, any
storms that are able to develop would have initiated from
incredibly unstable boundary layer parcels and would quickly
become severe. Steep mid-level lapse rates would enhance the
potential for large hail, and the resulting precip-loading would
yield an attendant damaging wind threat. Any outflow boundaries
could encourage additional development that may linger into the
evening hours, but it's unlikely than any cells would reach areas
as far southeast as the dallas fort worth metroplex.


Long term
Thursday onward
the extended forecast will feature the onset of an early
summertime feel with warm temperatures, high humidity, and
limited rain chances. The potential for widespread rainfall or
any strong severe storms appears minimal through early next week.

While the anomalous upper low responsible for several days of
widespread thunderstorms across the plains lifts northward through
midweek, another deep upper trough will develop across the western
half of the country by Thursday. Across the east, a building
bermuda high will place texas between these two features within
deep southwesterly flow. For Thursday and Friday this will mean
morning stratus intrusions followed by high temperatures climbing
into the upper 80s and low 90s with breezy southerly winds. The
combination of warm temperatures and high dewpoints will yield
afternoon heat index values in the low to mid 90s each afternoon.

This pattern will also be favorable for dryline convection far
to our west during the peak heating hours. All of this convection
should largely remain west or northwest of the forecast area as
the influence of the upper ridge along with diurnally-increasing
cin causes activity to weaken as it moves eastward. Will continue
to only mention some low storm chances across our northwestern
zones late Thursday into Friday when some of this decaying
activity could impinge on north texas. Otherwise, the extent of
the precipitation potential throughout this time will lie with
perhaps a couple warm advection showers just about anywhere in the
forecast area, although no more than a silent 10% pop seems

Similar conditions are generally expected over the weekend and
into early next week with limited rain chances and highs in the
neighborhood of 90 degrees. Additional thunderstorms look likely
to our west and northwest, with once again only a limited chance
for convection to be maintained within our cwa. The next question
mark in the forecast is a possible breakdown of the ridge early
in the coming week, as the upper low, which will have been parked
over the southwestern states for several days, finally begins to
advance east or northeast. One possibility is an eastward retreat
of the high which would allow the trough to encroach on the
southern plains and deliver a decent shot of showers and storms
around midweek. The other solution would be an east-west
elongation of the ridge while the shortwave energy lifts northeast
along its periphery, leaving us mostly warm and dry. Will only
show some low rain chances in north texas during the midweek time
frame at this juncture without a clear signal for any widespread
precipitation through the extended.

the anticipated moisture return can be clearly seen on satellite
now as a deck of low clouds is advancing northward across central
texas. Initially, a broken deck of MVFR clouds is expected,
followed by an overcast sky with a gradual decrease in ceiling
height. Guidance has significantly backed off on the potential of
ifr impacting waco as it appears any ifr will likely be across
the hill country. The reduced cloud heights will gradually advance
northward as the low level jet strengthens. Winds overnight will
remain out of the south, generally at or below 10 knots. As we go
through the day on Wednesday and the low level jet continues,
albeit weaker, momentum transfer from the strong winds above the
surface will lead to gusty conditions in the afternoon. Winds
could gust up to 25 kts at all TAF locations but shouldn't pose a
crosswind issue given its southerly direction.

The deck of clouds will remain in place through much of the day,
but with daytime mixing, ceiling heights are expected to rise to
vfr by mid-afternoon. TheVFR conditions will be short-lived as
the low level jet strengthens once again and leads to another bout
of MVFR by early Thursday morning.

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.
