.DISCUSSION...
Wx map shows high pressure over the eastern Gulf with low pressure
over the Plains yielding southerly flow over the region. GOES-16
visible satellite imagery shows the scattered/broken layer of
clouds over most of the region. Temps this afternoon are near
80/lower 80s, likely to rise a couple more degrees the next 2
hours.

The forecast this week will continue above normal temperatures,
with 3 more disturbances to affect the region.

The next upper level disturbance affecting OK this afternoon will
move across the region Monday, with the best chance of showers
and thunderstorms across Central Louisiana and north of the
region. SPC has shifted marginal risk of severe thunderstorms
further north. For Tuesday, our region expected to remain precip
free.

By Wednesday and Thursday, the next upper level low will bring
increasing chances of showers and thunderstorms by late Wednesday
morning, with the best chances Wednesday night into Thursday
morning. Models are a bit quicker on ending the precipitation
Thursday afternoon. SPC has portions of the region in 15% chance
for severe thunderstorms, and as expected, will be finer tuned the
closer we get to the event.

Friday, our region expected to remain precip free. By Saturday,
the next disturbance is a little harder to pinpoint with
intensity/timing, as significant spread continues among the long
range guidance.

as the pressure gradient increases between high pressure to the
east and low pressure over the Plains. Expect winds and seas to
diminish Tuesday, but increase once again Wednesday and Thursday
as another low pressure system approaches from the west, with
showers and thunderstorms likely by Wednesday afternoon into Thursday.
