What's New / NOTES
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Aviation
Like yesterday, today another challenging day for area tafs, but
mostly at waco, where current stationary front will be wavering
near the airport, before finally moving north as a warm front
tonight. Currently, ifr to low MVFR CIGS continue north of the
stationary front at waco, whileVFR broken cirrostratus continue
overhead at dfw area airports.

Dfw area airports will remain in a north flow regime, as north
winds around 5 kts become northeast or east-northeast 5-10 kts by
this afternoon.VFR will continue with light southeast winds 5-8
kts returning this evening. There is the potential for spotty MVFR
stratus around before sunrise Tuesday. However, fairly weak
boundary layer flow has me not introducing any cig restrictions at
this time.

As for waco, will begin them in MVFR through mid morning, before
the northward movement of the old stationary front combines with
heating and mixing to put the airport back inVFR. Did add vcsh
mid morning-midday, as they are still very moisture rich down
there with the front not too far to the south of the airport. As
the front approaches, then eases north through the airport from
midday to mid afternoon, felt vcts was a prudent add to the
forecast at MAX heating and with a surface focus around.

All north and central tx airports should be in south flow tonight,
but richest boundary layer moisture will remain around waco and
have re-introduced MVFR CIGS after 09z Tuesday.

Prev discussion issued 307 am cdt Mon may 29 2017
lingering scattered showers and storms have exited the forecast
area to the southeast as of 3 am. Just to the south, broad
troughing aloft is aiding isentropic ascent within a frontal zone
resulting in continued showers and storms across southern tx. We
may see an increase in activity again in our central tx counties
by late morning as CIN decreases and the environment recovers
from previous convection. Any activity will be isolated to
scattered without a well-defined surface boundary to focus
convection. However, the myriad of outflow boundaries which can be
seen via grk radar imagery may aid in development through late
morning; these features will begin mixing out later today and
should be non-factors during the afternoon. Any storms throughout
this time are expected to remain below severe limits due to very
modest lapse rates and instability, as well as weak shear less
than 30 kts. It's conceivable that a stronger multicell cluster
or two could produce some small hail or gusty winds, but storms
should struggle to become organized in the current environment.

Given the heavy rain across central tx last night where some
areas received 2-3 inches, additional localized flooding will be
possible with any prolonged heavy rain today. For north texas,
many areas will be dry today and several degrees warmer than
yesterday due to less cloudiness. Later tonight, we'll need to
keep an eye on the chance for some patchy fog to develop as skies
should be clearing out and winds will be very light. Have foregone
any mention in the forecast for now as there is very low
confidence in any precise location that could be affected.

Scattered showers and an isolated storm or two will be possible
again on Tuesday with rich moisture remaining over the area.

However, weak zonal flow aloft will keep activity very weak and
isolated. No severe storms are expected and many areas will remain
dry. A shortwave trough will begin to deepen to our west on
Wednesday which will lead to an increase in widely scattered
showers and storms across a large portion of the state. Much of
this activity in our forecast area will continue to be nuisance
showers and isolated storms with little no potential for severe
storms due to modest instability and very weak shear.

As the aforementioned trough translates eastward on Thursday,
showers and storms will become increasingly likely across most of
north and central tx. Thursday still looks like the best day in
terms of rain chances out of the next several days as the
strongest lift should impinge on the area during this time. A few
storms on Thursday could become marginally severe as mlcapes will
increase to around 1500 j kg and shear will increase to around 30
kts as a weak upper speed MAX becomes positioned overhead. Given
these parameters, a multicellular storm mode would be favored
capable of producing marginally severe hail and downburst winds.

Active weather should continue into the weekend with lower chances
for showers and storms Friday through Sunday. Models are trying
to bring a weak cold front through the southern plains on
Saturday, but latest indications are that this boundary would
stall somewhere in ok before making it into north tx. This setup
would maintain our positioned in a very moist warm sector with
weak ascent from a secondary upper trough that should slowly
drift across the southern us throughout this time. Therefore,
some low chance for scattered isolated storms should continue
into early next week.

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.
