Area Forecast Discussion
National Weather Service Little Rock AR
237 PM CDT Sat Mar 28 2020

.SHORT TERM...Tonight Through Monday Night
Two separate rounds of convection are expected during this period.

Data from KLZK radar indicate a broken line of convection, extending
from near Hope, to just east of Danville. Expect additional bow
segments to develop this afternoon, with the strongest activity
likely to affect northeast sections, across a region with the better
overall instability/shear profiles. All activity will form ahead of a
fast moving cold front, and should be east of the forecast area by
29/00z.

Another mid level system will approach from the west on Monday.
Forecast isentropic fields indicate strong moisture transport to the
region, setting up an elevated convective event for the forecast
area. Will need to monitor local areas for an excessive rainfall
potential for late Monday and Monday night.

 &&

.LONG TERM...Tuesday Through Saturday
Showers and some isolated thunderstorms will likely be ongoing
Tuesday morning as a cold front and weak upper level trough sweep
eastward through the state. However, by Tuesday afternoon conditions
should begin to improve as northwesterly flow aloft and weak high
pressure move into the region. We'll have a few days of dry weather,
but chances for rain will creep back into the forecast late next
week and into the weekend as a cold front moves through Arkansas.
The cold front will be associated with a stout upper level low
across the Great Lakes Region providing broad troughing over much of
the central CONUS in the mid and upper levels. This will allow
strong westerly flow aloft to persist through much of the forecast
period.

Mild temperatures will be in place to begin the extended period
forecast, however after the aforementioned cold front moves through
late next week, expect much colder temperatures to impact the state.
Highs will fall from the 60s and 70s to the 50s and 60s, and lows
will fall from the 40s and 50s to the 30s and 40s.

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

.DAY ONE...Today and Tonight

Showers and thunderstorms chances will increase today ahead of a
cold front that will move across Arkansas. Some strong and severe
storms will be possible, primarily over central and eastern
sections of the state. Damaging winds and large hail will be the
primary concerns, although isolated tornadoes cannot be rule out.
The severe weather threat will diminish later this evening as the
front moves east of Arkansas.

.DAYS TWO THROUGH SEVEN...Sunday Through Friday

The threat for hazardous weather will remain low through Sunday
night. However...showers and some thunderstorms will return to the
forecast Monday into Tuesday. There could be some potential for
strong to severe thunderstorms during this time frame...but
significant uncertainty exists on the overall track of this storm
system. As a result...refer to the forecasts in the coming days for
any changes to the potential for severe weather early next week. The
threat for seeing hazardous weather will then become low by the
middle of next week.

.Spotter Information Statement...

Spotter activation may be needed this afternoon and early this
evening.
