Area Forecast Discussion...UPDATED
National Weather Service Little Rock AR
1223 AM CDT Wed Apr 21 2021

.DISCUSSION...

Updated to include the 06Z aviation discussion below...

&&

.AVIATION...

Expect VFR conditions to persist through this TAF period. The
breezy winds seen earlier on Tue have relaxed...with generally
less than 10 kts sustained expected through Wed evening.

&&

PREV DISCUSSION...(ISSUED 243 PM CDT Tue Apr 20 2021)

SHORT TERM...Tonight Through Thursday

Here comes the late season freeze - high pressure dropping down
across the Plains is driving a cold front thru the area today.
Temperatures tonight are going to drop down to freezing or below
across about 2/3 of the forecast area. The southeastern zones will
likely be spared, but will remain quite cold regardless.

A rain/snow mix will persist across portions of northern Arkansas
this afternoon and tonight, but should clear out by morning. Little
to  no accumulation is anticipated.

As for the freeze warning, I had to expand it a bit. Some of the
counties included in the watch will only see freezing temperatures
in part of the area, however frost conditions are likely outside of
the freeze areas in those counties.

A trof sweeping across the midsection of the country will begin to
move east tonight, leaving the area under a northwesterly flow
tomorrow. In the wake of the cold front, temperatures will be on the
cool side tomorrow, topping out in the 50's across the north and the
lower 60's across the south.

Temperatures will drop down to rather cold levels again tomorrow
night, and frost is likely across portions of the north. Highs
Thursday will recover a bit, with max temperatures warming up 3-6
degrees in most areas.

LONG TERM...Thursday Night Through Tuesday

Upper low pressure will be over the northern Plains and desert
southwest to begin the long term period. The northern low will move
off to the east Friday and the southwest low will move into New
Mexico. The low will open into a trough and move through Arkansas
Saturday and to the east coast Sunday. Ridging returns to the
Plains Sunday and Monday.

A warm front will be in the Gulf of Mexico Thursday night and
Friday. This front will move north through Arkansas Saturday with a
trailing cold front. Showers and isolated thunderstorms will
overspread the area Thursday night and Friday, ending Saturday
morning. The bulk of the rain will be Friday and Friday night, in
the south, with up to two inches. High pressure builds in for the
rest of the period with warmer temperatures. Below normal
temperatures will become above normal by the end of the period.

Much colder condtions will be noted tonight, with temperatures
dropping down into the mid 20s to lower 30s. These subfreezing
temperatures will be seen generally along and northwest a line

Pocahontas. These areas will likely see a significant late season
freeze. Areas just southeast of this line could see temperatures
near or just above freezing, with patchy frost possible.

.DAYS TWO THROUGH SEVEN...Wednesday Through Monday

After near or subfreezing temperatures are seen across the
northwest half of the area Wednesday morning, the potential for
hazardous weather will become low by Wednesday afternoon.
Additional subfreezing temperatures could be seen across portions
of the area late Wednesday night into Thursday morning. Beyond

low.
