Area Forecast Discussion
National Weather Service Midland/Odessa TX
602 AM CDT SUN MAY 1 2016

See aviation discussion below.


An upper level storm system across Arizona will impact the west
Texas and southeast New Mexico terminals the next 24 hours
with increasing winds and clouds. Cloud bases will lower to
around 3500 feet (VFR) this morning at most terminals and continue
into this evening. Included a PROB30 group for MVFR conditions in
thunderstorms at KFST from 21z to 03z. Confidence was not high
enough to mention precipitation at any of the other terminals but
will continue to monitor. Generally north to northeast winds of 20
to 30 mph with higher gusts are expected through mid afternoon
and then diminish to 10 to 20 mph later this afternoon and evening.


.PREV DISCUSSION... /issued 349 AM CDT SUN MAY 1 2016/

The cold front that was hanging around the area yesterday will get
a good push south as high pressure builds into eastern New Mexico
and West Texas this morning. Already we are seeing increasing
north winds to our north with temperatures dropping into the 40s.
The strong cold air advection will be aided by increasing clouds
to give much cooler highs today than we have seen in quite a
while. No doubt the calendar day high in most locations will be
what the temperature was around midnight, but there is still the
question of the afternoon highs for today. The MET/MAV are both
showing highs around 20 degrees colder than those seen yesterday
and given pretty good run to run consistency, decided to stay
close to guidance highs for this forecast though did go a few
degrees above just in case there are some afternoon breaks in the
cloud coverage. Models have been trending lighter with QPF amounts
on rainfall today likely due to the upper low producing the rain
weakening as it moves northeast into the plains later today.
Therefore have lowered PoPs today and even those areas that do see
precipitation will probably only see light amounts.

The surface high will only slowly move east providing unseasonably
cool temps through Tuesday before the heat returns midweek. An
upper level ridge will develop over the Rocky Mountains late in
the week causing highs to rise back to near 90 degrees. Another
large low pressure system will move into the west coast over the
weekend and may provide our next chance for rainfall. Models are
showing some disagreement with the track of this low with the GFS
being the strongest and farthest south. It is showing some decent
QPF over the weekend for our CWA however it is also showing the
low weakening and moving northeast as it moves across the Rockies.
That would be very similar to the current low which models were
bullish with precip early on and are now backing off so will keep
PoPs low in the extended for now.
