DISCUSSION...

AVIATION...
South winds overnight will bring low clouds, some drizzle and fog
to much of Oklahoma and adjacent parts of northern Texas tonight.
MVFR and IRF conditions are likely before sunrise Saturday. These
conditions will last until midday in many areas before clearing
during the afternoon.

PREV DISCUSSION... /issued 244 PM CST Fri Feb 17 2017/

DISCUSSION...
An upper-level low will drift east across Oklahoma tonight,
while surface flow continues from the south. This low-level moist
flow will likely result in overcast skies, patches of drizzle, and
some fog early Saturday over most of central and southern
Oklahoma, and north Texas. Some clearing should occur in the
afternoon in the west, while the rest of Oklahoma remains mainly
cloudy.

Another storm system will approach the southern Plains by Sunday,
bringing much higher chances of measurable rainfall. Modest
instability should be adequate to support scattered thunderstorms
amid the widespread showers. There may be locally heavy rainfall,
and marginally severe storms Sunday night. The heaviest rainfall,
overall, should be over southeast Okalhoma.

The storm system then moves quickly off to the east, drying out
the southern Plains. There will be minimal effects on temperature,
as there not a significantly colder airmass following this
system.

Models continue to show a tightly-wound surface low pressure
system over the central Plains on Thursday. Assuming this happens
as advertised, that would result in a warm, breezy, and dry day
across Okalhoma and north Texas. Given that it will be late
February, those conditions suggest a substantial risk of
difficult-to-control grass fires.
