Severe Thunderstorm Warning 238, NWS Amarillo, TX

Area Forecast Discussion

.AVIATION...18Z TAFS...
VFR conditions should prevail at all TAF sites, with winds most
likely out of the north for the majority of the period. Some low
clouds over the Oklahoma Panhandle, may lead to brief MVFR cigs
at KGUY. Scattered low to mid level clouds expected to develop
this afternoon with isolated thunderstorms possible. No mention of
-TSRA in the TAFS, as it's expected that storms will develop east
 of the terminals. Most likely amended TAFS for VCTS or -TSRA will
 be for KAMA or KGUY. Right now confidence is not high enough to
 add to the package.

.PREV DISCUSSION... /Issued 426 AM CDT Tue Aug 14 2018/

DISCUSSION...

To sum up the highlights for the week ahead...rain chances nearly
every period and temperatures near to slightly above normal for this
time of year. Wednesday looks like the best chance overall for the
Panhandles regarding rain chances in the near term. Highs will
generally be in the mid-80s to mid-90s through the next week.
Widespread severe weather appears to be unlikely this week, but
localized strong to marginally severe weather (45-55mph winds and
upwards of nickel size hail) will be possible in some instances.

Upper level closed low was a little more stubborn than previously
forecasted, and its exit has been delayed until tonight for the most
part. Should get absorb into the main flow tonight across northern
portions of the CONUS which will ultimately put us in northwest flow
aloft. In the meantime, as we transition to northwest flow, storms
may linger around today through tonight across mainly central to
eastern portions of the Panhandles. Sometime tonight we will see a
lull in precipitation chances until they return Wednesday afternoon.
Severe weather is not expected tonight/tonight.

Another closed low appears to form tonight on the lee side of the
Rockies across eastern Montana/Wyoming. This could very well cause a
small perturbation to form south within the northwest flow Wednesday
into Wednesday night. This energy will be the focus for our next
round of precipitation chances starting tomorrow into tomorrow
night. Given the northwest flow, storms may very well form in
eastern New Mexico/southeastern Colorado and move east to southeast
across the Panhandles starting late afternoon or early evening
Wednesday. Again, severe weather is not anticipated at this time.

Rain chances essentially continue through the rest of the week.
Without getting into too much detail, northwest flow will
generally be featured in the upper levels which tends to give us
precipitation chances off the mountains. Details will be refined
for Thursday onward soon, but generally widespread severe weather
does not appear likely at this time. These patterns can be
difficult to pinpoint exact timing and coverage of rainfall, but
generally most areas could see at least some chance for rainfall
over the next several days.
