This hazardous weather outlook is for portions of northern...
western...central...and southern Oklahoma...and western north
Texas.

.DAY ONE...Today and Tonight...

.Thunderstorms...
Showers and thunderstorms will continue to move across portions of
Oklahoma this morning, with the most widespread activity along and
north of I-40. A few of these storms could become strong with
small hail and gusty winds. Otherwise, locally heavy rain and
lightning will be the main concerns. This activity is expected to
end later this morning.

For this afternoon and evening, there is a risk for severe storms
across the entire area with the highest potential in parts of
north central and central Oklahoma, generally east and north of a
line from Cherokee and Weatherford, to Lawton and Pauls Valley, to
Holdenville Oklahoma.

A warm front is expected to continue to lift north into parts of
northern Oklahoma by this afternoon with a dryline extending
southward from where it meets the warm front in northwest
Oklahoma. A cold front will then move across the area this evening
and overnight. Additional thunderstorms could develop near the
dryline and/or the warm front late this afternoon although the
highest potential for storm development will be with the cold
front. Strong to severe storms will be possible again later today
between 4 pm and midnight with very large hail up to the size of
baseballs and damaging winds over 60 mph. Some tornadoes will
also be possible with the highest potential across portions of
north central and central Oklahoma, including Stillwater, Oklahoma
City metro, and Lawton, just to name a few locations.

.Heavy Rain...
Heavy rain could lead to localized flooding in some areas through
tonight.

.Fire Weather...
Near critical to critical fire weather conditions will be possible
this afternoon in parts of southwest Oklahoma and western north
Texas due to low RH, gusty winds, and dry vegetation behind the
dryline.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday...

.Thunderstorms...
After a brief break Tuesday, severe storm chances will return
Wednesday afternoon and evening across much of Oklahoma and
western north Texas. All hazards will be possible.

The rest of the work week into the early part of the weekend will
then be dry with low thunderstorm chances returning to parts of
the area on Sunday.

.Heavy Rain...
Heavy rain which could cause flooding will be possible again
Wednesday into early Thursday.
