concerns: pockets of lifr ceilings this morning east of dfw,
scattered thunderstorms this afternoon across the region.

Goes-16 satellite imagery reveals a deck of cirrus clouds over
most of the region this morning. WhileVFR currently prevails at
all TAF sites, a few sites just east of dfw are reporting lifr
ceilings. Latest obs at dfw and dal have reported few to sct 007,
and opted to add a tempo bkn005 until 13z to account for the
potential of poor flying conditions. Weak low level flow and a
larger spread of dew point depressions may inhibit lifr ceilings
from reaching the eastern metroplex sites.

As a shortwave approaches north texas from the west and another
along the texas coast provides forcing, there remains a potential
for scattered thunderstorms this afternoon and evening. The best
potential remains across the eastern sites, including dfw, gky,
dal, and act. However, outflow boundaries from stronger
thunderstorms that develop this afternoon may initiate convection
and impact the western TAF sites as well. Given the scattered
nature, confidence in timing is low and will likely be adjusted in
subsequent TAF issuances.

In the extended portion of the forecast, guidance has hinted at
the return of MVFR ceilings Wednesday morning, but confidence is
too low to warrant a mention at this time. Otherwise, southerly
winds will prevail through the forecast period.


Short term issued 331 am cdt Tue jun 25 2019
today and tonight
quiet weather is expected Tuesday morning, but another round of
scattered showers and thunderstorms is expected once again as
weak impulses provide some forcing across our moist and unstable
environment. A weak mid level shortwave is progged to slide
across the region later this morning, while another shortwave will
translate along the texas coast. Model soundings reveal
precipitable water values ranging from 1.5 to 1.75 inches Tuesday
afternoon, as well as a favorable profile for disorganized
strong to marginally severe thunderstorms (mucape values from
2500-3500 j kg, mid level lapse rates of 6-7.5 c km, and 0-6 km
shear from 20-25 knots at best). Weak capping should begin to
erode as afternoon temperatures reach the upper 80s and low 90s.

The main hazards with any strong to severe thunderstorms would be
hail and gusty winds.

Maintained the highest pops across the southeastern zones through
the late morning and afternoon, but scattered showers and
thunderstorms across the region are possible during the evening
hours given the possibility of outflow boundaries initiating
convection and the favorable environment. Most activity should
dissipate with the loss of daytime heating. Otherwise, overnight
lows in the low to mid 70s and southerly winds can be expected
Tuesday night.


Long term issued 331 am cdt Tue jun 25 2019
Wednesday onward
through the extended portion of the forecast, the large scale
pattern will transition from progressive westerly flow to one more
reminiscent of summer. A building ridge will overspread areas to
our north and northwest, while an easterly wave feature drifts
along the gulf coast. This setup will keep the potential for
organized severe storms (like our last few events) quite low
through the extended forecast, with convection consisting largely
of diurnally-driven thunderstorms with a localized threat for
downburst winds.

On Wednesday and Thursday, light northerly flow will exist aloft
as an upper ridge elongates to our west and northwest. We'll
remain along the eastern periphery of this ridge, removed from
the strongest subsidence. As a result, some afternoon convective
attempts may be made on Wednesday, particularly east of i-35 where
greater moisture will reside. A slight eastward expansion of the
ridge may limit precip chances within the forecast area on
Thursday. After some below-normal temperatures the previous few
days, highs will return to near normal in the low to mid 90s.

Slightly lower afternoon dewpoints should hold heat index values
below 105.

Friday through the weekend, the 500mb ridge will become centered
to our northwest, positioning us within easterly flow aloft. An
easterly wave drifting along the southern edge of the ridge could
allow for additional afternoon convective chances through next
weekend. However, activity is not expected to be very widespread,
and a majority of the CWA should remain dry through this time
period. The weak shear within the easterly flow regime should
limit convective mode to disorganized multicells during this time,
although instability will remain quite high. Similar
temperature dewpoint trends will continue, with heat index values
expected to remain below advisory criteria.

Rain chances may increase a bit early next week as a tutt low
becomes positioned near the texas coastal bend. Increased
cloudiness may keep highs a couple degrees cooler early next week
as well. With the ridge still displaced from the region, so too
will be the potential for widespread triple-digit temperatures.

Some near- or slightly below-normal temperatures may exist for at
least the first few days of july.

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.
