00z tafs
generally poor flying conditions are expected through the evening
and overnight hours with widespread ifr lifr CIGS and
occasionally-reduced visibilities.

Plentiful low-level moisture remains in place through the lowest
3-4 kft which will result in persistent CIGS around 500-700 ft
this evening. These CIGS are expected to lower to lifr later
tonight where they will persist into early Saturday morning. In
addition, occasional mist and drizzle may lower visibilities at
the TAF sites overnight. However, ascent is actually expected to
decrease slightly over the next 3-6 hours which may limit
occurrences of precipitation. While some patchy fog is possible at
the TAF sites, am expecting low stratus to be favored over fog
based on the near-surface hydrolapse in recent model soundings.

Winds will remain fairly light out of the east or southeast
overnight while a weak warm front nudges northward.

Early Saturday morning, a pacific front will sweep through the
taf sites from west to east associated with a strong surface low
moving through oklahoma. This will turn winds to the west while
also resulting in a brief window for rain showers and perhaps a
thunderstorm. However, the greatest potential for any convection
will remain well east of the TAF sites, and will continue to
handle this possibility with a vcsh mention at this time. This
boundary will quickly scour all low-level moisture from the area,
and any low CIGS will rapidly dissipate, likely by 14-15z.VFR
will then prevail.

Later Saturday morning and Saturday afternoon, wind speeds will
increase as 30-40 kt west southwest winds mix down to the surface
behind the pacific front. This will pose some crosswind issues,
particularly on n-s oriented runways, as sustained winds remain in
the 20-25 kt range with gusts of 30-35 kt possible throughout
Saturday afternoon. Just after 00z, the system's trailing cold
front will move through the area, turning winds to the northwest,
while also decreasing their speed. Have included this mention in
the extended dfw taf, and it will be introduced at all other
airports in subsequent tafs.


Short term issued 315 pm cst Fri feb 22 2019
tonight through Saturday
satellite imagery reveals an upper level low moving east across
arizona this afternoon with a conveyor belt of pacific moisture
streaming northward across mexico and east texas out ahead of it.

The western flank of this pacific plume appears to be where this
afternoon's convective activity is occurring as an upper level
disturbance lifts across the area. These showers and storms should
move on out to the northeast over the next few hours as the
disturbance heads towards the ARKLATEX region. The primary weather
concern for the evening will be the return of fog and drizzle due
to the overrunning pattern currently in place. There may be
additional dense fog to contend with during the late evening and
overnight hours, and wouldn't be surprised of another dense fog
advisory were needed at some point tonight.

The upper low will move fairly quickly east tonight and will be
accompanied by a pacific front, which will enter our western
counties during the pre-dawn hours Saturday. The front will be
devoid of moisture and lift until it reaches the i-35 corridor,
where a broken line of showers and isolated storms will pop up
around sunrise Saturday. The latest guidance holds off developing
deep convection until the system reaches the eastern-most row of
counties, where strong to possibly severe storms will be possible
during a narrow window Saturday morning. These storms will exit
quickly to the east by mid Saturday morning, giving way to dry and
breezy conditions area-wide behind the front.

West winds will increase rapidly late Saturday morning due to a
tight post-frontal pressure gradient, particularly across the
northwest half of the region where 20-30kt sustained winds along
with 30-40kt gusts will be possible by midday. For this reason, a
wind advisory has been issued for areas along and northwest of a
line from sherman to dallas to comanche from 9 am until 6 pm
Saturday. Grass fire danger will be elevated during this time as
temperatures climb into the 60s, but wet fuels should preclude a
critical fire weather threat. These winds should decouple and
drop off fairly quickly around sunset Saturday evening.


Long term issued 315 pm cst Fri feb 22 2019
Saturday night through Friday
with the deep surface low rapidly pulling northeast into the great
lakes Saturday night, surface wind speeds will gradually diminish
through the nighttime hours as high pressure builds into the
region. Although there will be a lack of significantly colder air
behind the front, it will be cool on Sunday with highs topping out
in the upper 50s.

The upper pattern will remain fairly zonal through the upcoming
week with only weak disturbances embedded in the westerly flow.

The first of these will pass through the southern plains on late
Tuesday. Low level moisture will increase ahead of this
disturbance late Monday into Tuesday resulting in increasing
cloud cover and warmer temperatures Monday night. Some low rain
chances will spread into our far southeast counties on Tuesday,
but these should be short lived as the upper disturbance quickly
moves east.

As we get further into the week, model guidance diverges with
respect to the next upstream disturbance. The ECMWF is a little
more amplified and allows a cold front to slide southward into the
area late Wednesday while the GFS is a little slower and holds the
front off until later Thursday. Either way, we'll maintain some
low chances for rainfall Wednesday night into Thursday and trend
temperatures a little cooler for the end of the week.

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.
