Aviation
/12z tafs/
significant crosswinds are expected at the dfw airports today,
with some crosswind impacts also expected at kact. A strong upper
level low currently over northwest oklahoma will continue moving
east across the plains today dragging a potent surface low through
oklahoma. A tight pressure gradient will result in west winds of
20-30 kts with gusts of 30-35+ kts.

Dfw airports: north-south runways will be impacted with the
strongest winds occurring between 17z-00z. Between 16-21z,
diagonal runways at kdfw may also be severely limited due to a
slight west-southwest component, but the wind direction should
become slightly west-northwest after 21z. Wind speeds will
diminish around sunset and then fall to less than 10 kts this
evening. The winds will shift back to the southwest and south
Monday morning.

Waco airport: wind speeds will be slightly less than the dfw
airports due to a farther distance away from the surface low.

However, strong winds of 20g30kts will likely still have a
crosswind impact on the runways. Wind speeds will quickly
diminish around sunset, becoming light and variable.

a deep upper level low can be seen on IR and WV imagery lifting
northeast out of the texas panhandle into northwest oklahoma. The
strength of the forcing associated with the system is displayed by
the ongoing elevated precipitation occurring well behind the
surface front. This activity is moving from west to east across
the forecast area, and is primarily stratiform rain with
occasional embedded thunderstorms. The bulk of the convection has
remained just south of the CWA where higher amounts of elevated
instability are present. Precipitation should continue to shift
east through the early morning hours, eventually exiting the
eastern-most counties by mid morning.

As the rain exits, our main concern will shift to strong gradient
winds associated with the narrow surface pressure gradient behind
yesterday's cold front. It will be a windy day across just about
all of the region, and wind advisory criteria will likely be met
across the northwestern half of the cwa. A wind advisory will
therefore be issued for areas roughly along and northwest of a
line from sherman to waxahachie to goldthwaite. Wind speeds should
become sustained near 25 mph in the advisory area with gusts 35
to 40 mph this afternoon. Outside of the advisory area, winds near
20 mph with gusts around 30 mph can be expected.

Temperatures will be well below normal today with highs ranging
from the low 60s along the red river to the low 70s in the
lampasas, temple, cameron and surrounding areas. Mostly clear
conditions and diminishing wind speeds tonight should allow just
about all locations to drop into the 40s by sunrise Monday.

A quick warm-up is expected Monday and Tuesday as the upper low
heads northeast, heights increase and return flow ensues. The
departure of the upper level low will position north and central
texas beneath a northwest flow aloft regime for the first half of
the work week. A shortwave trough will drop quickly southeastward
from the pacific northwest, reaching the southern plains by
Wednesday. The system will be accompanied by another cold front,
which should move southeast into our northwest counties late
Tuesday night or Wednesday morning. Moisture and instability ahead
of the front should be sufficient for scattered convection as lift
from the shortwave arrives.

There could be some strong convection as the front crosses the
red river, but time of day may initially suppress the severe
threat. Better chances for severe storms may occur as the front
interacts with a more unstable airmass later in the day Wednesday
across the southern half of the cwa. It's still a tad too early
to make a definite call on if severe weather will occur, but
given the time of year alone, there will probably be at least a
low-end possibility.

Precipitation should quickly push southeast of the region along
the cold front Wednesday night or early Thursday. The shortwave
trough will deepen and cut-off over the southeastern states
during the second half of the week, which should place north and
central texas beneath a strengthening upper ridge. This should
result in nice weather as we head into next weekend.
