Area Forecast Discussion
National Weather Service Jackson MS
1219 PM CDT Thu Apr 15 2021

.UPDATE...
Updated for 18Z aviation discussion

&&

.AVIATION...
18Z TAF discussion:

Morning thunderstorms and low ceilings have since moved out of the
area with the one exception being HBG/PIB/LUL where MVFR ceilings
will likely hang on for a few more hours before finally pushing
east. VFR conditions will prevail at all terminals through the
remainder of the TAF period. Cloud cover will increase again
tonight, but ceilings are expected to remain VFR. Winds will be
out of the north. /TW/

&&

.DISCUSSION...

A weak wave embedded within zonal flow aloft that was responsible
for overnight showers and storms has pushed east of the area this
morning. As such, the majority of activity has cleared the area
with only a few lingering showers across the Hwy 98 corridor.
Cloud cover will also decrease from north to south with most areas
along and north of I-20 seeing partly cloudy skies by late this
morning if not already. Temperatures are expected to warm into the
upper 60s to low 70s area wide this afternoon. The main change to
the forecast was to update the PoPs as precipitation moves out
along with minor tweaks to sky cover, otherwise the ongoing
forecast remains on track and no additional changes were needed.
/TW/

Prior discussion below:

Today and Tonight...

Rain showers will continue across areas south of I-20 today through
mid morning but these showers are expected to dissipate before noon.
After showers exit the region, we will be rain free for the rest of
the day and partly clear skies will prevail across the north. Much
of the southern half of the CWA will still experience mostly cloudy
skies. High temperatures will be in the lower 70s for most locations
with an exception of a patch of temperatures in the upper 60s
across the extreme northwest. As we enter into the night time, a
rain free evening will prevail however shortly after midnight,
rain chances will increase from west to east as a cold front
moving across the Plains, begins to approach the ArkLMiss. Low
temperatures tonight will be in the mid 50s./JNE/

Friday through Wednesday night: Cooler than normal temperatures are
expected through the period. The period will start off wet but dry
weather is expected by Sunday and will last through the middle of
next week. Moisture will increase more earnestly from the southwest
Friday ahead of a developing surface low in response to a potent
shortwave tracking east across the central Plains towards the mid
Mississippi valley. Our PWATs will surge above and inch and a half
along and south of Interstate 20 by mid afternoon and continue into
Saturday morning before getting knocked down by drier air in the
wake of a cold front. Overall, instability will remain limited and
help mitigate the potential for severe storm development but
rainfall of one to three inches in a short amount of time Friday and
Friday night over nearly saturated soils will lead to the potential
for runoff issues and flash flooding. Wl highlight this "Limited"
threat in our HWO generally along and south of the Interstate 20
corridor. Model consensus suggests the surface low will track east
along the Gulf coast through Saturday and the rain will slowly taper
off from the northwest Saturday as the surface low moves farther
away from our CWA. Unfortunately, it looks like it will take until
Saturday evening for the rain to end over our southeast most zones.
Sunday is expected to be dry in our CWA despite a shortwave moving
from the Ozarks to the Tennessee valley that may bring the chance of
rain to north Mississippi. A few additional shortwaves look to swing
across our region through Wednesday and a cold front on Wednesday
but no measurable rainfall is expected in our CWA through Wednesday
night. /22/
