Discussion...
a pre-frontal surface trough continues to March across the Texas
Panhandle. Behind the trough, winds have switched around to the
north which has slowed the warming potential across western Oklahoma
and northwestern Texas Panhandle. The cold front is still slowly
making its way across southern Colorado and Kansas. A shortwave
remains on track to move across the panhandles later this evening
and overnight and bring a chance for showers behind the cold front.
Overnight lows will remain above freezing so any precipitation that occurs
should be in the form of all rain. Precipitation chances remain largely
unchanged with the highest chances across the Oklahoma and northern
Texas panhandles while the lowest remain across the southern and
western Texas Panhandle. Precipitation will come to an end Thursday
afternoon as the shortwave moves east of the area. The combination
of the cooler Post-frontal airmass and being cloudy for the majority
of the day will hold daytime high temperatures in the middle to upper
50s.

Friday remains dry as brief upper level ridging builds over the
panhandles. Surface winds will also return to a southwestern
orientation to allow temperatures to warm into the 70s area wide.
But another upper low will lift northeastward from southern Arizona
Friday afternoon into Sunday and bring another round of precipitation
chances for the weekend. Weak instability will also allow some
rumbles of thunder Saturday and Sunday. No severe weather is
expected at this time.

Ridging will slowly build across the panhandles starting Monday to
bring a return to dry and warm conditions.

Fire weather...
neither elevated nor critical fire weather conditions are expected
for the next 7 days due to relative humidities remaining above 20
percent.

Ama watches/warnings/advisories...
