421 PM CDT Thu Mar 22 2018


Tonight through the day Friday:

Quiet conditions are expected through the day tomorrow although 
clouds will be on the gradual increase, especially north of the I-20 
corridor. Aloft, the far western extent of a minor "clipper" wave 
advancing toward the east CONUS trough axis will be inducing 
isentropic upglide (ergo, clouds) upstream of our region where some 
light precipitation will also exist. But, as mentioned, in our neck 
of the woods all that should manifest is mid to high layer clouds 
with conditions tending to moderate quickly as surface high pressure 
transitions to the east. Through tonight the high is close enough to 
keep winds light and variable over most of the region, but by 
tomorrow low-level southerly flow will commence in all areas by the 
afternoon. In fact, these surface southerly winds could a bit gusty 
at times from midday through the afternoon hours in portions of the 
Arklamiss Delta, although at this time thinking is that gusts and 
speeds will remain low enough to refrain from mentioning in the 
HWO/graphics. Temperatures will continue to trend upward but 
scattered clouds will make forecasts of minimum and maximum temps a 
little tricky, especially in northern zones. /BB/

Friday night through next Wednesday tomorrow:

Expect above normal and warm start to the weekend before heavy 
rain potential ramps up by mid-late next week.

Overall they synoptic pattern on Saturday morning will consist of 
trough departing off the eastern seaboard while mid-level ridging 
will be building into the area from the west. This will support the 
strong surface high, that has brought below normal low temperatures 
into lower 30s and some frost, to build off the southern Atlantic 
seaboard. In addition, a mid-level shortwave will be propagating 
through the mid-Mississippi Valley, helping lead to surface low over 
Missouri area and better southerly return flow and some gusty winds. 
This boundary and moisture return look to be the best in the Highway 
82 corridor, where some rain & storm chances can't be ruled out on 
Saturday. Some of that may extend a little closer to the I-20 
corridor but overall should remain in our northern areas. This 
pattern of rain and some storms will persist through the weekend, 
with a stalled front lingering in the Highway 82 corridor to Golden 
Triangle & east Mississippi, which will keep some light rain chances 
around. Due to increasing warmth and moisture advection, we should 
still top out in the mid-upper 70s to low 80s in the south under 
cloudy skies. This will help temperatures remain well above normal 
Saturday morning in the mid-upper 50s (~10 degrees above normal) and 
in the low 60s (~12-15 degrees above normal). During this time, 
couldn't rule a stronger storm or so but overall limited forcing 
should limit any more organized potential.

As the strong subtropical ridge builds over the southern Gulf of 
Mexico & into the Carribean early next week, the mid-level ridge 
axis will extend through the Appalachians and northeast. This will
support a continued warm and cloudy period with some light rain 
and storm chances around. As the ridge axis builds to the east, 
expect warmer and muggy conditions with cloudy skies and most rain
chances over the western portions of the area.

The pattern around the middle of next week will become more 
amplified and consist of a deep mid- level trough digging into the
Desert Southwest and better influx of Pacific moisture into the 
southern Plains and mid-Mississippi Valley. This will help a storm
system develop, which will be the main focus. As strong southwest
flow, upper divergence and increasing influx of moisture feeds 
along a stalled surface boundary into and just northwest of our 
region, heavy rain and a significant flash flooding potential 
will be possible. This is somewhat similar to the February heavy 
rain event just to our northwest, but with the subtropical ridge 
centered over the southern Gulf, it is slightly different. 
Uncertainties remain on how this pattern is going to iron out, but
a significant flooding threat will exist near the mid- late 
portions of next week. Most of the heaviest axis will remain just 
off to our northwest by Wednesday but newer 12Z Euro has sped up a
lead shortwave bringing the heaviest rain in just after the end 
of the forecast period. In addition, due to increased warmth, 
moisture and stronger southwest flow aloft, some severe threat 
could be possible around mid-late next week. Main takeaway is to 
keep a close eye on this pattern mid-late next week as small 
synoptic differences could make a large differences on impacts 
across the region. /DC/
