.SHORT TERM...
(Today)
Issued at 300 AM CDT Sun May 5 2024

Showers and storms will overspread the area today as
an upper trough axis will lift northeast from TX
into AR and MO tonight. Pockets of heavier rainfall are
likely to occur just about anywhere across the forecast
area through the afternoon. Locally higher rainfall amounts
today and saturated soils from previous convection across
the area will maintain the flash flooding threat. Rain will
begin to taper off from SW to NE this afternoon and evening as
the upper trough lifts through the area. That said, the current
expiration time of 00z Monday for the flood watch looks good and
will leave as is.

.LONG TERM...
(Tonight through Saturday)
Issued at 300 AM CDT Sun May 5 2024

Lingering rain across the NW AR zones should end by 06z, leaving
the forecast area dry for rest of tonight much of the daytime on
Monday, though some model data hints at some elevated shower and
storm potential Monday afternoon across SE OK and NW AR, so will
keep a low Pop in those areas. Focus turns to storms that develop
along the dryline to west later Monday afternoon in conjunction
with an upper trough that lifts from the mountain west region into
the high plains Monday afternoon and evening. Potential for some
significant severe weather will exist with storms that northeast
Oklahoma late in the afternoon or more likely Monday evening.
Greatest coverage/higher end severe potential continues to favor
NE OK and NW AR Monday eve/night. Despite lower storm coverage
roughly from I-40 to the south, the environment will remain
supportive of a higher end severe threat with any storm that
develops. Coverage will diminish late Monday night and Tuesday
morning, leaving most much of the area in a lull. However, will
keep though low PoPs across the eastern sections of the forecast
area Tuesday and Tuesday night. An uptick in storm chances will
come Wednesday with a cold front that enters the area, with some
severe potential in place ahead of the front Wednesday afternoon
and evening. The boundary will push through the area by Thursday
morning. Cooler and drier air will filter into the area starting
Thursday. An upper trough in NW flow aloft will clip the area
Friday, and may produce a few showers across NE OK and NW AR,
however will leave PoPs out for now. Otherwise, settled conditions
are expected for the remainder of the forecast period.
