Discussion...

Thin high clouds over Oklahoma and North Texas will gradually move
east through the morning. With abundant sunshine and a gusty
southerly wind, fire weather will be a concern by this afternoon.
Wind gusts above 30 mph will be common during the early afternoon,
especially across central and north central Oklahoma. With
afternoon humidity rather low (25-30 percent), fire weather
conditions will certainly be elevated.

High clouds will return by tonight through Tuesday, as a system
over the Pacific northwest approaches within northwest flow aloft.
A cold front will also move across the area on Tuesday, with
breezy northerly winds developing behind the front. Most of the
cooler/colder air with the front will not move into the area until
late Tuesday and Wednesday. Therefore, another day of elevated
fire weather conditions are expected Tuesday afternoon.

Cold/cool surface high pressure will build over Oklahoma and North
Texas late Tuesday and early Wednesday. As high pressure builds
east during the day Wednesday, a southerly wind will return,
especially across western Oklahoma.

A surface trough will shift east across the Southern Plains on
Thursday bringing a weak wind shift. However, rather mild
temperatures can be expected. The wind will increase on Friday
with well above average temperatures. Afternoon humidity will be
rather low across western Oklahoma where temperatures will be
warmer. This will result in elevated fire weather conditions.

Another front will move across the area early Saturday. This will
bring temperatures closer to average for the weekend.
