Area Forecast Discussion...UPDATED
National Weather Service Jackson MS
625 PM CST Sun Feb 14 2021
.UPDATE...
Updated for 00Z aviation discussion
&&
.AVIATION...
00Z TAF discussion:
A mix of IFR/MVFR cigs wl prevail at all sites through the TAF
period. The initial round of -FZRAPL is moving through the ne.
Wl see increasing chances after 06Z from west to east of FZRA,
PL, and SN which will impact each TAF site to various degrees
through Monday. Combined with cold ground conditions, freezing
rain accumulations on airport runways and parked aircraft will
be a concern through the TAF period. /22/NF/
&&
.DISCUSSION...
This Evening through Monday Night:
A wave of sleet and freezing rain showers is currently moving across
the forecast area this afternoon, and it will continue to produce
sleet and ice across primarily areas of Mississippi north of
Interstate 20 through the evening. Elsewhere, light freezing drizzle
and the occasional light shower of freezing rain, sleet, or light
snow will still be possible. Persistently cold air temperatures and
ground temperatures mean that any precipitation through tonight will
cause impacts as it lands on roadways and bridges. Zooming out to
the bigger picture, the main shortwave trough to our west is
crossing the Southern Plains today. A deep swath of moisture being
advected north over our shallow Arctic air mass can be seen as
colder cloud tops on water vapor and infrared satellite imagery over
East Texas and Oklahoma this afternoon. As this greater lift and
moisture spreads east with the approaching trough overnight, the
forecast Winter Storm will develop across our area into tomorrow.
Threat impact areas are largely unchanged from the going forecast,
but we did decide to outline an area of "Extreme" threat from
freezing rain to the Hazardous Weather Outlook text and graphics.
Details are included in the precip type/amounts section. Extremely
dangerous temperatures are also expected Monday night (lows from 5
degrees in the Delta to 15 in the Pine Belt), and that threat
remains unchanged in the HWO text and graphics.
Winter Storm Timing: Temperatures will continue to drop tonight,
with even the Pine Belt waking up to temperatures around freezing in
the morning. Delta temperatures will be in the mid-teens range.
Short-term guidance is in good agreement that the onset of our next
round of precipitation will be around Midnight in northeast
Louisiana and southeastern Arkansas. By 2 or 3 a.m. Monday, wintry
precipitation will begin to overspread portions of western
Mississippi and extend across the eastern half of Mississippi by 6
a.m. The main wave of heavier precipitation looks like it should
move across the forecast area between 6 a.m. and around 3 p.m.
Monday. As the axis of the shortwave trough passes overhead through
the evening, colder and drier air will begin to undercut the
precipitation and subsidence aloft will bring and end to precip from
west to east. It would not be a surprise to seem some linger
freezing drizzle or flurries into the Monday night hours, but
accumulations should end by the evening.
Precipitation Types/Amounts: Given the Arctic air mass in place
heading into tonight and tomorrow, the biggest factor in determining
precip type will be the depth of warm air in the elevated warm layer
and the intensity of precipitation. For the sake of the forecast, it
has been assumed most accumulating precip will begin as snow aloft,
experience at least partial melting, and then refreeze as it falls
through the subfreezing boundary layer. In far southeast Arkansas,
far northeast Louisiana, and Delta counties of Mississippi, it's
expected that precip type will be mostly snow after a brief period
of freezing rain and sleet. In those areas, colder boundary layer
temperatures and less warm air aloft should allow heavy
precipitation to overcome any partial melting. Snow and sleet
accumulations of up to 4 to 6 inches could occur in these areas.
Through more central portions of Louisiana and a southwest-northeast
corridor of central Mississippi, the depth of warm air aloft looks
to sustain primarily freezing rain and sleet through most of the
event. Precip totals will be tricky depending on type, but generally
expect up to 1 to 2 inches of sleet and snow, and between one
quarter to three quarters of an inch of ice from freezing rain. The
Extreme threat area lies where the consensus of guidance indicates
these greater ice accumulations. More widespread damage to trees and
power lines is expected through this corridor. Lastly, the far
southeastern and eastern portions of Mississippi will most likely
see either rain or freezing rain through most of the event, with
periods of sleet mixing in with heavier precipitation. Up to around
one half inch of sleet and up to around one quarter inch of freezing
rain is expected in those areas. Expect some possible errors in the
gradients between primary precip type areas. /NF/
Tuesday through Saturday:
After an extremely cold night, temperatures Tuesday will remain
quite cold despite the clearing skies. The shallow arctic airmass
and the frozen precipitation on the ground will prolong the cold
conditions as highs for most of the area remain in the 20s with
30s in the far southeast and lows Tuesday night dropping back into
the teens and 20s.
The persistent mid level southwest flow will bring the next system
into the area Wednesday with another round of wintry weather
possible. The track of the surface low looks to be further north
with this system as it hugs the northern Gulf coast. While the surge
of warm air in advance of the system will be strong, the leftover
ice will serve to hang onto the cold air at least until the heavier
precipitation begins. Thus, northwest portions of the area will
remain cold enough for long duration, accumulating winter weather
again Wednesday into Thursday.
Another surge of cold air will follow this system, but high pressure
shifting quickly east by the weekend will turn the wind to the south
and allow for a warmup to begin Saturday as 40s and 50s are expected
with values near 60 over the far southeast. /GG/
