This Hazardous Weather Outlook is for a Large Part of Arkansas.

.DAY ONE...Today and Tonight

Patchy fog will be noted this morning, with dry weather today.
Heading into tonight, isolated to scattered showers should develop
over southern Arkansas.

.DAYS TWO THROUGH SEVEN...Tuesday Through Sunday

A storm system over the southwest United States will interact with a
stalled front along the Gulf Coast to bring good chances of rain
Tuesday and Tuesday night. Isolated thunderstorms are expected as
well.

Through dawn Wednesday, two to three inches of precipitation is in
the forecast from Little Rock southward. Locally heavier totals are
possible. Farther north, there could be a quarter inch of rain
toward the Missouri border, with half inch to inch and a half
amounts farther south toward Interstate 40.

The system will pass through on Wednesday, with rain ending. Dry
and mild conditions will hold through Thursday before a cold front
surges through the region from the northwest on Friday. The front
will bring another round of showers, followed by colder air and
below average temperatures.

The front is expected to stall just to the southeast of Arkansas
this weekend. A lot of moisture will surround the front, with
chances of rain continuing over the southeast half of the state.
Moisture will be lacking away from the front farther northwest, but
it may be cold enough for a few snow flurries.

Subfreezing air may get into central sections of the state Sunday
night. This may lead to pockets of freezing rain.

.Spotter Information Statement...

Spotter activation will not be needed.
