What's New / NOTES
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
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.

12z tafs
morning satellite imagery shows an increase in cloud cover across
north texas compared to this time yesterday. Most of the increase
is from mid and high cloud cover spreading in from the west.

Scattered showers and thunderstorms are ongoing across parts of
west texas and this will continue through the period, sending
bands of high clouds across the area today. Most of the
precipitation should remain west of the airports today but could
have some impacts on westbound arrivals departures.

There is a band of lower cloud cover spreading north out of the
hill country and has already made its way into waco. Temporary
MVFR CIGS can be expected with this through the morning. We'll
continue to monitor its northward progression, but at this time
will leaveVFR conditions prevailing in the metroplex. Outside of
some morning low clouds,VFR conditions should prevail today with
southeast winds around 10 kt. Rain chances will increase some
during the day Tuesday with the bulk of the heavier rain remaining
off to the west.


Short term issued 308 am cdt Mon sep 25 2017
today and tonight
the main forecast concern through tonight will be ever slowly
increasing rain chances mainly west of i-35. Water vapor imagery
shows a large upper trough extending over much of the western u.S.

And into texas this morning. This large trough has several smaller
embedded vorticity maxima which will rotate through the main
trough over the next several days.

For today, most of the shower and thunderstorm activity will
remain well west of our area. A persistent band of low and mid
level isentropic ascent will be in place across west texas
extending northward into western oklahoma and kansas. This area
is also on the eastern periphery of stronger forcing from the main
upper trough. Showers and thunderstorms should increase in
coverage through the day as stronger forcing for ascent spreads
through west texas. We may see some of this activity move into our
far western counties later this afternoon and we'll have the
highest pops generally west of a bowie to lampasas line. Lapse
rates are unimpressive and overall instability is weak through
tonight across the region, so the severe weather threat will be
low. Winds fields are modest for this time of year though and
oriented in a way that would support training convection. This is
most likely to occur west of our area, but nonetheless does bear
watching. Any training convection could produce locally heavy
rainfall. Temperatures today will continue to be several degrees
above normal and could be impacted by increasing cloud cover.

We'll still be looking at highs in the upper 80s and lower 90s

Eastward progression of the upper trough is expected to be slow
and the main cold front associated with this system is expected to
only make slow southward progress into oklahoma overnight
tonight. This means the best rain chances will remain well west of
i-35 through tonight.


Long term issued 308 am cdt Mon sep 25 2017
Tuesday onward
the deep upper low across the western us will remain there
through midweek, generating multiple waves of showers and
thunderstorms across eastern new mexico and west texas. In
addition, its associated cold front will slowly approach north
texas and will eventually increase our rain chances Wednesday
through Friday. However, the most widespread rainfall and highest
totals are expected to remain west of the forecast area. Increased
cloud cover and cooler air behind a pair of fronts will result in
some cooler (near normal) temperatures, especially for the end of
the week and the upcoming weekend.

On Tuesday, the front should still be located just wnw of the
forecast area, draped roughly from san angelo to oklahoma city.

Widespread showers and a couple thunderstorms should be ongoing
along this axis of increased lift, some of which will drift into
our western counties Tuesday afternoon and evening. As activity
moves east however, it will slowly decay as it outruns forcing
from both the front and broad ascent ahead of the upper trough.

Lapse rates will also be very meager, and much of the rain
showers may be lightning-free due to the lack of
instability forcing. As will be the case for much of the week,
locations west of i-35 will have the highest rain chances, with
some spots to the east remaining hot and mostly dry.

Similar trends should be expected on Wednesday, although by this
time, the slow-moving front will have finally drifted into north
texas. This front should bisect the forecast area into a cooler
and rainy western half with a continued warm and mostly dry
eastern half. Despite the front being in the vicinity, we'll still
be lacking upper dynamic forcing as the trough will begin
retrograding westward with upper ridging building in to take its
place. As a result, there will be a battle between lift from weak
convergence along the front against some broad subsidence from
building heights aloft. This should act to limit the extent of
shower thunderstorm activity through Wednesday and even into
Thursday with the highest rain chances continuing to be west of
i-35. A similar setup should still exist on Thursday with the
front moving just slightly farther southeast, but still positioned
within the forecast area. Since rain rates amounts are expected
to remain on the lighter side, am not anticipating much in the
way of heavy rain or flooding issues at this point; these
concerns should be confined to locations west of the forecast

Rain chances will begin tapering off to the south on Friday as
the front finally sinks southward. This will be due to flow aloft
becoming more zonal, causing the ejecting shortwave to allow a
secondary push of cooler and drier air to move southward through
the plains. Lingering showers and a few storms will be possible
through central tx most of the day Friday, while rain chances
shut down across north tx with the arrival of drier air. This
scenario would mean a fairly pleasant early fall weekend for most
of the region with temperatures near normal and mostly dry

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
