Area Forecast Discussion

.DISCUSSION...
Updated for 18Z Aviation Discussion.

.PREV DISCUSSION... /issued 952 AM CST Tue Feb 19 2019/

UPDATE...Morning Update.

&&

.DISCUSSION...

Forecast looks in fairly good shape although we are seeing a bit
more lightning/thunder earlier than expected approaching North
Mississippi. High temperatures may be a bit warm over North
Mississippi as well due to ongoing rain and Northeast flow. Made
minor adjustments accordingly. Rain should overspread the entire
Midsouth this afternoon. Afternoon highs should make it into the
low to middle 40s...but should continue to warm overnight.

.PREV DISCUSSION... /issued 552 AM CST Tue Feb 19 2019/

Latest IR satellite imagery depicts high clouds covering the
region this morning. These clouds the precursor to a very active
weather pattern. Latest radar imagery depicts some light
precipitation falling across portions of north Mississippi
already this morning. Given temperatures are near or below freezing
in many locales have added a mix of rain and sleet through 9 AM,
primarily for N MS. Meanwhile, mid level analysis depicts
southwesterly flow aloft over the region, while at the surface
winds are from the north as high pressure is centered to the NW.

Showers will gradually overspread the region by this afternoon as
a warm front lifts north toward and over the region by the early
hours of Wednesday. This front will be aided by a LLJ of up to 60
knots nosing into the region this evening. This mass moisture
transport will produce near record PWAT values this evening
through Wednesday evening. Model guidance suggests Tuesday PM
values will be between 1.25 and 1.50 inches for most of the
region, with portions of N MS near 1.60 inches and up to 1.75
inches by late Wednesday. These values would all be above the 99th
percentile for February. This will result in several rounds of
heavy rainfall, and even a few embedded thunderstorms, this
afternoon through Wednesday evening.

As such, a Flash Flood Watch goes into effect for the entire area
this afternoon and continues through 6 AM on Thursday morning. By
that point in time, some 2 to 4 inches of rain will have fallen
over the area. The latest QPF has the axis of maximum rainfall
during through late Wednesday roughly along a line from Paris
southwest through Memphis and west to Forrest City. This heavy
precipitation, in addition to the recent wet conditions, will
lead to areal, river, and flash flooding for Tuesday and
Wednesday.

Rain will temporarily cease by early Thursday as high pressure
pushes in from the west. Periods of sun will be possible during
the day on Thursday as the high moves over the region. While
Tuesday afternoon highs will only be realized in the 40s, highs on
Wednesday and Thursday will be in the 50s to near 60. The lack of
precipitation will be short lived, however, as a shortwave aloft
embedded in the southwesterly flow leads to showers by late
Thursday for most of the area. A warm front moves through the
region by Friday afternoon, allowing moderate rain to fall with a
few embedded thunderstorms, as PWAT values again climb to abnormal
values for mid to late February.

By early Saturday a deep trough has dug its way into the Southern
Plains, which leaves the water hose of southwest flow aloft wide
open over the region. Not only does this set the stage for more
heavy rain Friday and Saturday, but the upper trough takes on a
bit of a negative tilt on Saturday, acting to juxtapose shear and
instability for a few strong to severe thunderstorms during the
afternoon and evening hours of Saturday. The SPC currently has
most of the region highlighted for this threat on Saturday.

As a cold front clears the region by early Sunday, dry conditions
finally return. However, the region will have received some 4 to 8
inches of rainfall from the Tuesday to early Sunday time frame.
This will likely necessitate another Flash Flood Watch for the
late week time frame. Surface high pressure remains over the
region for Monday, but models converge on yet another shortwave
and thus rainfall for the region again next Tuesday.

.AVIATION...18Z TAFs

Advancing warm front will gradually lower conditions from VFR to
IFR and LIFR this period with mainly moderate showers and
embedded thunderstorms. Scattered storms likely to be near the
sites for a prolonged period of time with highest confidence at
TUP for on station activity. Easterly winds will be gusty through
the period veering southerly and diminishing some before cold
front pushes through. Low level wind shear expected outside of
thunderstorm activity. Improving conditions late at MEM and JBR.
