concerns---MVFR ceiling cessation. Low potential for -sn or pl at
waco early Tuesday morning.

MVFR stratus continues to gradually lift as slightly drier air
invades from the north.VFR doesn't appear likely to return
until just prior to sunrise. Northerly winds will remain elevated
in the 15 to 20 knot range with occasional gusts to near 25
knots. As the main upper trough slides eastward, there will be a
non-zero potential for some -sn and or pl at waco. At this time,
the better ascent looks to remain just south of the airfield, so
i've left explicit mention of this out of the TAF for now. Trends
will need to be closely monitored for inclusion of this later
this morning, however. Nevertheless, impacts should be low given
the amount of air traffic and expected precip rates at kact.

Cavu should be the rule after 00 utc Wednesday with winds
subsiding down below 10 knots.

Update issued 1123 pm cst Mon nov 12 2018
quick update to add in a mention of snow flurries and or sleet
down across central texas.

Upstream observations across west texas indicate pretty decent
ascent was ongoing and was resulting in elevated echoes. While not
much of this activity was reaching the ground here, it seems
reasonable that once these echoes translate eastward may
encounter a bit more moisture. Still, sublimation will be
necessary to help to wet-bulb the dry 630-850mb layer---which
seems possible. Assuming sufficient sublimation, it's conceivable
that flurries or light snow and or light sleet pellets will be
possible via seeder-feeder type processes. All that to say that
there is a low chance for some wintry precipitation across central
texas on Tuesday morning. Most importantly, however, impacts
should be quite negligible given the windy conditions (not
allowing for any settling of precipitation in one particular place)
and likely relative warmth of road surfaces.

Updated products have been transmitted.

regional radar imagery shows most of north texas dry at this hour
with only a few lingering areas of mainly light rain across our
far eastern and southeastern counties. There was one little patch
of light reflectivity that moved across montague county over the
last hour and bowie actually reported -sn on its 2 pm observation
with a slight reduction in visibility. Bowie fire department
confirmed a few minutes of flurries in the area. Otherwise, most
areas will remain precipitation free through the night.

Strong isentropic descent will continue through the nighttime
hours which will help erode the lower cloud deck as much drier air
works its way to the surface. Skies should be mostly clear by
early Tuesday morning and it will be quite cold with a brisk north
wind continuing. Temperatures are already near freezing across our
northwest counties and the freezing line will make steady
southward progress through the night. Most areas will be in the
mid 20s to near freezing by early Tuesday morning. Our northwest
counties will drop into the lower 20s. Wind chills will be in the
teens overnight.

Mostly sunny skies are expected on Tuesday, although it will
continue to be cold. Highs will only top out in the upper 30s to
near 40 degrees with wind chills holding in the upper 20s and
lower 30s through the day. Tuesday night looks like it will be the
coldest night of the week as a 1035 mb surface high settles over
our northwest counties. Winds will decrease to less than 5 mph
under most clear skies which should allow for near optimal
radiational cooling. Forecast lows will be in the low to mid 20s
areawide. Some of our outlying cold spots protected from any wind
could drop well into the teens.

The center of the upper trough axis will actually pass right over
north texas Tuesday night, but it will be starved for moisture, so
no clouds or precipitation is expected. As it passes to the east
on Wednesday, we'll start to see a light southerly wind become
established and temperatures will begin to climb. Highs should
warm into the mid 50s on Thursday and mid 60s by Friday. Another
weaker front should approach the area over the weekend and could
bring a small shot for rain, but we'll keep the forecast dry at
this time.

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.
