.DISCUSSION...
Much quieter weather across North Texas this evening with the
exception of strong westerly winds. The powerful upper low is
located across the Southern Plains with 40-50 kt of westerly mid
level flow, much of this mixing down to the surface. Over the last
few hours there have been numerous wind gusts in excess of 40 mph
including a 58 mph gust at Wichita Falls. The winds are expected
to diminish later this evening as the upper low moves off to the
northeast and the current wind advisory will be allowed to expire.

There is some remnant mid level cloud cover associated with
moisture wrapping around the back side of the upper low. This
cloud deck is primarily across the northern two rows of counties
up to the Red River. Clouds are expected to thin later tonight
with the departure of the upper low. It will be a cool night
across North Texas with lows dropping into the lower 40s in many
areas. If winds can diminish completely in outlying rural areas,
we may see some upper 30s.

Tomorrow looks like a nice day across the region with light
southerly flow returning and warmer temperatures expected under
sunny skies. Highs areawide should climb into the upper 70s and
lower 80s.

On Tuesday, the upper pattern will amplify just off the west coast
of the U.S. allowing a trough to deepen over the Rockies. At the
surface, pressures are expected to fall across the Texas Panhandle
allowing southerly flow to strengthen across our area and
transporting moisture northward.

On Wednesday a warm front will spread northward ahead of the upper
trough which is expected to swing right across North Texas. This
should allow at least parts of the region to become unstable by
midday. As the upper trough progresses eastward, another strong
cold front is expected to swing through North Texas. Scattered
showers and thunderstorms are expected to accompany the front and
much of North Texas should see at least some precipitation during
the day on Wednesday. As of right now the threat for severe
weather appears pretty low, although lapse rates will be steep to
at least be concerned with a hail threat. Precipitation should end
from north to south rather quickly Wednesday evening.

Beyond Wednesday, the weather looks pretty quiet through next
weekend with cooler temperatures behind the cold front on
Thursday. Highs will generally be in the 70s and lower 80s 
through the weekend with little chance for precipitation.

.AVIATION...
/ISSUED 123 PM CDT Sun Apr 30 2017/
/18Z TAFs/

The powerful cyclone responsible for the inclement weather on
Saturday is swinging through the Southern Plains today. Although
the thunderstorms are now well east of the region, the storm 
system will continue to impact North and Central Texas with strong
west winds. An airport weather warning is in effect through 23Z
for consistent gusts in excess of 35kts; some gusts will exceed 
40kts. This will cause considerable crosswind issues, and DFW will
likely keep afternoon operations confined to 31L/R. The direction
may veer a bit north of west as the afternoon progresses, but this
will only slightly ease the crosswind concerns. Conditions will
improve around sunset as the low departs, and the boundary layer
stabilizes. Broad surface high pressure will dominate Monday, with
the winds likely backing to the southwest. South flow will prevail
until the next front and thunderstorm chances arrive on Wednesday.
