Vis and cigs vary at the moment across TAF sites. A few sites that
haven't received RA yet are VFR at the moment however, conditions
are expected to worsen as the day progresses. FG impacting HBG and
PIB and may be slow to clear due to low clouds. A mix of mainly

.DISCUSSION...
Today and Tonight:
A very saturated day will be on tap for the ArkLaMiss region
today and tonight. A tropical like airmass has been consistently
reigning over the region for the past few days and has aided in
some very efficient rain fall.
At the surface, a stalled frontal boundary to our north and a
surface low moving east out of the ArkLaTex region will help
initiate showers/storms and heavy rainfall today. Soundings have
been consistent with 2+ inches PWs and skinny CAPE profiles. This is
typically a good indicator of heavy rainfall. A good bit of rain
fell across the region yesterday so additional rainfall today will
make some areas even more prone to flash flooding. While we aren't
expecting the 12+ inches of rain like our neighbors in the Texas
region, a good portion of our area could see up to 6 inches with
locally higher amounts. Although we are currently in a "lull", as
the surface low across the ArkLaTex region continues to move east
early this morning, rainfall will become more widespread by dawn.
The heaviest rainfall is expected across most areas west of I-
55, northwest Mississippi, and central Mississippi. For now will
continue with the current HWO flood graphic, however upgrades may
be needed after this forecast package depending on this
overnight/early morning trend of rainfall. Since sticking with
current HWO will keep the same areas for the current Flash Flood
Watch however, depending on how conditions develop, will add
additional counties as needed. With soils already saturated, trees
may be easier to fall and won't take much for low lying and urban
areas to flood. Please do not drive in flooded waters and contact
local stations and or state departments of transportation for
road conditions.
On the bright side of things, temperatures will be in the mid to
upper 70s which are below normal values for this time of year.
Increased cloud cover and the rain will help limit warm temperatures
for the next couple of days. I know there hasn't been much talk
about river flooding but minor to moderate rises could be possible
depending on how much rain certain areas get. It is suggested to
check for updates via our website, social media, or phone! /JNE/
Wednesday through Monday:
The current synoptic setup looks to remain in places through
Wednesday night, which means the threat for flash flooding and
river flooding will continue be our main concern through that
time. High moisture content in the tropical air mass along the
Gulf Coast, a west-east oriented stationary front, and slow-
moving low pressure system will support slow-moving and/or
training thunderstorms with efficient rainfall rates over some
portion of the area. The latest suite of high-res model guidance
indicate some locally heavy rainfall amounts in excess of 5-7
inches from now through the Wednesday time frame - centered
around portions of far northeast Louisiana, far southeast
Arkansas, and west-central Mississippi. As mentioned above, the
saturated soils will make flash flooding and river flooding more
likely with any concentration of heavy rain. The threat for flash
flooding has been extended through Wednesday night in the
Hazardous Weather Outlook text and graphics, and the current flood
watch is likely to be extended in time with subsequent forecasts.
By Thursday, the front should be gradually pressing southwards
toward the Gulf Coast as the low pressure system moves east away
from our region. Somewhat drier air will build into northern
portions of the area, but chances for heavier rain will linger in
the south where moisture is deeper into the weekend. Then surface
high pressure and mid-level ridging will begin to dominate the
regional weather patterns for early next week as the Bermuda High
builds westward over the Southeast CONUS. Expect some rebounding
of temperatures and rain chances with the return of southerly
flow. /NF/
