...THE FLASH FLOOD EMERGENCY CONTINUES FOR MUCH OF GRENADA COUNTY 
AND NORTHERN CARROLL...

...THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 115 PM CST FOR
NORTHWESTERN CARROLL AND GRENADA COUNTIES...

At 1038 AM CST, Doppler radar indicated heavy rain across the warned 
area. One to three inches of rain have fallen over the past three 
hours onto already flooded or saturated areas. Numerous homes remain 
flooded, in addtion numerous roads closed or flooded. Flash flooding 
will continue across the area.

This is a FLASH FLOOD EMERGENCY for much of Grenda County, including 
the city of Grenada and northern Carroll county. This is a 
PARTICULARLY DANGEROUS SITUATION. SEEK HIGHER GROUND NOW!

Some locations that will experience flooding include...
Grenada, Leflore, Jefferson, Teoc, Elliott, Avalon, Bew Springs,
Holcomb and Malmaison.

Additional rainfall amounts of one to three are possible in the 
warned area.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Move to higher ground now. This is an extremely dangerous and
life-threatening situation. Do not attempt to travel unless you are
fleeing an area subject to flooding or under an evacuation order.

Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.

Area Forecast Discussion...UPDATED
National Weather Service Jackson MS
649 AM CST Fri Feb 22 2019

...HEAVY RAIN ISSUES CONTINUE IN THE ARKLAMISS DELTA WITH SEVERE
THUNDERSTORMS LIKELY IN PORTIONS OF THE REGION SATURDAY...

.UPDATE...
Updated for 12Z aviation discussion

&&

.AVIATION...

12Z TAF discussion:
Generally poor flight conditions to start the period as a stalled
frontal boundary in our region has led to very low stratus and
periods of DZ and SHRA. Some TSRA also possible especially after
18Z, but chances to impact any particular site were generally too
low to include in the TAFs at this time. Ceilings in the IFR to
LIFR range will continue through around 15Z, with some scattering
and lifting of the stratus deck expected to mix in some MVFR and
even VFR ceilings after that. Increasing chances for IFR ceilings
to return by 06Z at all sites. /NF/

&&

.DISCUSSION...

The surface frontal boundary that has been plaguing our region
for quite a while now is hung up just north of coastal MS and
basically running right through HBG. Model consensus is insistent
this boundary will make good progress north today as a warm front,
but long experience with predicting movement of this front
informs a forecast decision to not get too aggressive with
northward movement. But even with that in mind, there is high
confidence locations from MEI...to JAN...to HEZ (and points south)
will break well out into the 70s by the afternoon with high
levels of moisture to trigger MLCAPE values easily up to the
neighborhood of 1000 j/kg. Farther north, the gradient of
temperatures will be quite tight from north to south and still
some locations in the Arklamiss Delta (such as GLH) will probably
fail to reach 60 degrees.

This temperature contrast alluded to above is driving a strong
southwest to northeast upper jet just northwest of the region with
impressive northward warmth and moisture advection at 850 mb
aimed up toward the Arklamiss Delta. The baroclinic zone aloft
here, along with the other mentioned factors, continues to spur
heavy rains and embedded thunderstorms streaming across the
northwestern quarter of zones. These areas (and points to the east
down the highway 82 corridor) are very saturated due to rains the
past several days and have little tolerance for more heavy rain,
which is exactly what they are still getting right now from
Winnsboro LA to Grenada MS and points northwest, where some flash
flood warnings continue. Training heavy rainfall will try to focus
a little farther northwest through today and tonight, but the
threat for flooding is still enough to keep the inherited flash
flood watch in effect through Saturday for northern and
northwestern zones going. The highest risk for flooding will be
getting a bit more confined toward the Arklamiss Delta today and
tonight when the SIGNIFICANT flooding risk will be focused in the
HWO and graphics. Farther south, it will be hard to rule out some
locally torrential downpours through Saturday causing flooding
issues and thus the LIMITED flood risk for much of the rest of the
area will be kept going.

But, overall, expect the focus in our region to be gradually
transitioning more toward severe weather potential, especially on
Saturday into Saturday evening (and especially north of the I-20
corridor). This afternoon into this evening, the building
instability (mentioned in the first paragraph) will also present
some, but only MARGINAL, severe threat, primarily along and west
of the I-55 corridor. There is definitely a question mark as to
how much intense thunderstorm activity will actually develop with
access to good low level instability owing to generally weak
forcing this afternoon (and a bit of dry air in the 850 to 700 MB
layer) over central and southern zones. However, if deep
convection can manifest (that is rooted near the surface) in these
areas then there will be plenty of deep layer shear to organize
supercell structures. Good news is that low level shear this
afternoon will not be enough for more than a low end tornado
threat. We anticipate the risk for isolated severe storms will
become more confined to the Arklamiss Delta by late this evening
into the overnight hours. All this will be mentioned in the HWO
and graphics.

The warm front that will be trying to push north through the
region today will definitely be getting entirely north of the
region later tonight into very early Saturday. This will, of
course, allow warmth, moisture, and related instability to quickly
work north through the entire region in advance of the southern
fringe of a potent disturbance aloft set to come into the region
midday Saturday through Saturday evening. Surface low pressure
associated with this system will be well to the northwest of the
region, but low pressure will be deepening rapidly and ensuring
pressure falls well away from the center (and into our region).
Dropping pressures in the low levels will help develop high low
level shear (especially across the northwest half of the region)
in conjunction with high deep layer shear caused by
west/southwest 500 mb winds of 60 to 70 kts. Hope has been that
model consensus would trend farther north with favorable severe
weather parameter space associated with this event, but latest
model runs have shown this not to be the case. Considering the
above, the Storm Prediction Center has slightly expanded the
ENHANCED severe risk (including the risk for significant severe
weather and strong tornadoes) a little farther south into north-
central and northwestern zones with a SLIGHT RISK elsewhere
(except in portions of SE MS where the highest risk is currently
only at a MARGINAL level).

The main timing window of severe weather potential on Saturday
still seems to be from midday through early evening, although
some risk could begin a little earlier in far northwestern zones
and end a little later in far eastern zones. A mixed mode of
severe weather is anticipated with at least a broken squall line
probably taking shape across a large portion of the region by late
in the day into the evening. But the highest severe potential
will likely come from isolated supercells that will probably form
in advance of any sort of MCS and the risk of these supercells
will be highest in north-central and northwestern zones. In
addition to the tornado threat, there will also be a risk for
damaging wind gusts and large hail. The HWO and graphics will be
updated to represent details of timing and impacts.

The cold front coming in the wake of the storms late Saturday
night will usher in more seasonable and dry air for Sunday and
Monday. There is a still a good deal of uncertainty after Monday
and going through the rest of next work week because of poor model
consensus. That said, the more reliable (at that time range) European
model continues to be largely dry through most of the long range
and chances of rain were kept relatively tame. Expect temperatures
to remain generally near seasonal values in this time frame,
although there will be opportunity for persistent colder air to
our northwest to spill in before the official forecast period is
over. /BB/
