1010 AM CDT Sun Apr 23 2017
Wrap around moisture from surface low located over the Tennessee
River Valley will continue to cover a majority of the eastern
portions of the forecast area for the remainder of the morning
into the early afternoon hours. Clouds should thin out and break
up later this afternoon as surface low moves further to the east
and upper level trough pushes through allowing for a more deeper
northwest flow and subsident air to help erode cloud deck.
Otherwise, gradient between the low and surface ridge centered
over west Texas will allow the northerly breezes to persist
bringing in mild conditions this afternoon and chilly temperatures
tonight. On-going forecast looks to be on track and no significant
changes at this time.
.PREV DISCUSSION... /issued 656 AM CDT Sun Apr 23 2017/
For 12z TAF issuance.
Sfc analysis shows sfc low over nwrn GA with wrap around low
clouds extending swwd into most of the forecast area this
morning (primary exception being sern TX where mainly mid-level
cloud cover is noted). Some very light precip is mixed in with the
clouds, mainly across lower Acadiana and in the form of
drizzle...and likely not heavy enough to even make it into the
obs, thus no precip is being carried at this time. The cloud cover
should continue to push ewd with the low, leaving behind VFR
conditions by mid-morning at KLCH/KAEX and noontime KLFT/KARA.
Other story today looks to be the elevated nrly winds as CAA
continues in wake of the cold front.
PREV DISCUSSION... /issued 246 AM CDT Sun Apr 23 2017/
DISCUSSION...High pressure is centered over the Texas Panhandle
this morning. The ridge will build east through today and become
centered over our area by Monday Morning. Monday Morning`s lows
will be the coolest of the stretch and be around 10 degrees below
normal, for a change.
By Monday Afternoon the ridge axis will shift east of the area
allowing the return flow to begin. Breezy south winds can be
expected Tuesday and Wednesday as low pressure moves through the
plains along with a gradually warming trend. The plains low will
sweep into the Great Lake Region by mid week which will send
another cold front through the northern gulf coast
Wednesday/Wednesday Night. This front is expected to be weaker
with only a modest and brief cool down.
The onshore flow will quickly return for late in the week and the
weekend as another area of low pressure moves across the plains.
MARINE...Strong north to northwest winds will continue this
morning, however winds will slowly subside through the day as
high pressure builds in. Light winds are expected for Monday as
high pressure moves overhead, however south winds will increase
through Tuesday as low pressure moves across the plains.
