3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.
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.

06z tafs
MVFR CIGS of around 1500-2500 ft agl are occurring across the
forecast area with p6sm vis and gusty southeast winds. Expect cigs
to lower to ifr around 500-900 ft agl for kjct, ksoa and kbbd
after 08-09z with vis 3-5 sm possible. Ifr CIGS could occur
briefly at kabi and ksjt, but confidence too low to include in
tafs. Low clouds should clear out from west to east 18-21z, with
primarilyVFR conditions then expected 21z today to 03z Sunday.

Scattered showers and isolated thunderstorms will likely develop
and move east through the region through 15z before diminishing
15-21z. Best chances for prevailing -shra will be at kabi, with
mainly vcsh south of the big country. Southeast winds will
continue through 12z before becoming southerly around 12-15z, then
southwest 15-18z, then west to northwest 18-21z and then finally
north after 00z Sunday as a cold front moves through. Surface wind
speeds mainly 5-15 kt with local gusts to 22 kt through 18z
before becoming 10-20 kt with gusts to 28 kt after 18z. Llws
possible at ksjt through 13z due to lighter surface winds at that
site.

00z tafs
currently seeing MVFR ceilings developing across the southern
terminals early this evening and this trend will continue,
with MVFR ceilings filling in across the northern terminals
by mid to late evening. Ceilings will likely lower to ifr
across the southern terminals after 07z. Gradual improvement
is expected on Saturday, with ceilings lifting scattering out
toVFR by afternoon. Scattered showers will develop from west
to east overnight. Highest confidence is at kabi and will
maintain a mention of -shra after midnight, with only vcsh
across the remaining terminals. Expect gusty southeast winds
across the northern terminals overnight, shifting to the west
and northwest Saturday afternoon.

short term...

(tonight and Saturday)

Continued cool with good rain potential
The forecast for the next 24 hours still includes good rain chances
for mainly tonight, with decreasing chances for tomorrow. As the
trough axis of the upper storm system moves close to west central
texas tonight, the potential for showers and thunderstorms will
increase. With the better upper dynamics across our northern
counties, that's where we have better rain chances, mainly in the
70% to 80% range. However, 40% to 50% chances extend south to our
interstate 10 corridor. Although the amount of rainfall may vary
greatly, across west central texas tonight, most areas should
receive at least a few hundredths of an inch; but, some areas may
receive amounts around a quarter inch. The severe thunderstorm
threat does not look very high for tonight and Saturday; however,
spring is the time of year for severe thunderstorms. For tomorrow,
the upper trough axis moves east of our area, and rain chances end,
from west to east. Another cold front tomorrow afternoon will bring
winds from the north, along with cooler air; the cooler air will
help maintain temperatures closer to seasonal normals for at least a
few days.

Long term...

(Sunday through next Friday)
.Expect quiet weather for the first half of the week before
rain and thunderstorms chances return toward the end of the
week...

the overall all weather pattern will transition toward a more
normal spring-like pattern across west central texas. Northwest
flow aloft will develop by mid week and interact with a series of
surface fronts progged to move across the region. Chances of
showers and thunderstorms will be possible with these frontal
systems. Any rainfall will be welcomed as both abilene and san
angelo have recorded only a trace of rain so far this month.

(Sunday through Tuesday)
an area of low pressure will continue to slowly slide
southeastward across eastern texas, allowing the cool, north wind
to persist across the area on Sunday and Monday in the wake of
the frontal passage. Look for highs in the 70s under partly
cloudy skies. We will see a little more sunshine on Monday but
temperatures will remain at seasonal normals with highs in the
mid to upper 70s. Surface high pressure begins to build across
much of northern texas by Tuesday and winds will begin to veer
back to the south-southeast. Moisture will be slow to advect into
the area as winds will be light for much of the day on Tuesday.

With clear skies and plenty of sunshine, temperatures will warm
into the mid 80s Tuesday afternoon.

(Wednesday through Friday)
a trough-ridge-trough pattern will develop across the CONUS and
northwest flow aloft will develop and persist across western texas
for the rest of the week. A cold front will be moving south across
the central plains Tuesday and approach the area by Wednesday
morning with another cold front forecasted to approach the area
Thursday night Friday morning. Showers and thunderstorms will be
possible with these fronts. The limiting factor will be the amount
of moisture we will be able to advect into the region ahead of
these fronts. A deep moisture profile will help develop more
widespread shower and thunderstorms development. A more shallow
moisture profile will limit development and greatly reduce
rainfall totals and coverage. Severe weather is not expected at
this time with any thunderstorms that my develop.
