Area Forecast Discussion
National Weather Service Mobile AL
339 PM CST Mon Feb 10 2020
.NEAR TERM UPDATE /Now Through Tuesday night/...A surface cold front
has moved to near the Natchez Trace at noontime. Shortwave energy
continues to stream northeast over the Southeast on the north
side of an upper ridge over the Gulf of Mexico/Southeast,
resulting in a broad area of southerly 35 to 55 knot low level
flow along and southeast of the front, along with scattered rain-
showers and a few thunderstorms over the region. Greatest activity
has been just northwest of the forecast area, with some
convection spilling over northwestern and western portions of the
forecast area. Guidance is advertising an increase in the low
level flow later this afternoon into tonight as the region sees an
uptick in passing energy. Am still expecting best coverage to
remain just northwest of the forecast area the rest of today into
tonight, then a decrease later tonight into Tuesday as the
quantity of passing shortwaves decrease. Best instability at this
time remains along and west of the Tombigbee River. With the best
combination of instability, wind shear (latest SPC analysis
advertising 50-60kts of bulk shear over Mississippi at this time),
and surface convergence being northwest of the forecast area, am
expecting any strong to severe storms to generally remain
northwest of the forecast area as the low level flow increases
again this afternoon into tonight.
Tuesday into Tuesday night, the surface front stalled northwest of
the forecast area shifts south over the forecast area in response
to another round of shortwave energy moving northeast over the
region. This front ultimately stalls north of the northern Gulf
coast. A shortwave system digging south over the desert southwest
combined with the upper ridge over the Southeast building north a
bit will bring a weaker low level flow more parallel to the
sinking front, but strong/perpendicular enough for numerous
showers to the forecast area as the front sags south over the
region. Instability in the model soundings remains small to nil
due to the influence of the upper ridge, so have left thunder out
of the weather grids.
The next item to deal with is fog chances tonight into mid week.
Guidance, both physical and statistical, continues to advertise
advection fog forming as warm, most Gulf air flows over the cooler
near-shore waters and coastal bays (latest water temperatures
reported in the 55-60F range). A dense fog advisory has already
been issued for portions of the marine zones, and will add a dense
fog advisory for coastal land areas with this afternoon's
package.
Not to forget, temperatures well above seasonal norms are expected
through Tuesday night. High temperatures generally in the low
70s, with low temperatures generally in the low to mid 60s
expected.

.SHORT TERM /Wednesday Through Wednesday night/...A weakly
organized upper low located over New Mexico at the beginning of
the day moves northeast on the west side of the Southeast upper
ridge. Additional shortwave systems move into a mean upper trough
over the Plains directly behind the New Mexico system. This
combined upper dynamics pushing against the Southeast upper ridge
with strengthen/shift southeast low/mid/upper level jets over the
Lower Mississippi/Tennessee River Valleys and Southeast. Low
level flow becomes strong enough to shift the stalled surface
boundary back north as a warm front. Modest (MuCapes approaching
500-1000 J/kg) instability, along with 0-6km bulk shear values of
50-75kts spreads north over the region south of the warm front.
Looking at the wind profiles, a general linear nature will lead to
a squall line developing and moving over the area, though enough
low level directions shear is present (0-1km helicities of 100-200
m^2/s^2) for rotators to form. Best combination of all the
ingredients remains over the Lower Mississippi River Valley
shifting northeast into the Tennessee River Valley, with SPC going
with an Enhanced Risk over this area. The ingredients remain
strong enough over the forecast area for SPC to paint a Slight
Risk for severe storms over the forecast area for Day Three,
though. Timing at this point is for severe weather affecting the
forecast area in the late afternoon at the earliest into Wednesday
night time frame. Timing has been decently good in the guidance
so far. /16 &&
.EXTENDED TERM /Thursday Through Monday/...The upper trough
centered over the central US will quickly progress eastward on
Thursday. A surface low will quickly move into the Northeast US and
a adjacent cold front will push through the area. Showers and
maybe a few thunderstorms will be possible Thursday before
clearing behind the front Thursday night. Once the front clears
surface high pressure will build over the Ohio River valley. Drier
air will move in Friday through Saturday as the surface high
quickly moves east. By Sunday, upper level ridging will quickly
build over the southwest Atlantic in the wake of the upper trough.
Southwesterly flow aloft will return Sunday leading to moisture
returning for the beginning of next week. Another wet pattern is
expected to start next week as several shortwaves are expected to
pass through the southwesterly flow regime. Exact timing and
locations of the best rain chances are fuzzy at best but the
overall pattern would support more rainfall. We will have to
monitor our rivers as many will be swollen from this weeks
rainfall and ongoing flooding could be exasperate.
Temperatures will feel like the first little bit of a big roller
coaster. Temperatures will drop to more seasonable values behind
the front Friday and Saturday with highs in the upper 50s and lows
in the 30s. Much like a drop on a roller coaster, these "cooler"
temperatures will not last long and we will quickly rise back up
into the 70s for highs and 60s for lows by Sunday into Monday.
This warmer weather will likely persist for as long as the upper
level southwesterly flow continues. BB/03

.MARINE...Light to moderate flow on the west side of a low level
ridge stretching west over the northern Gulf of Mexico expected
through mid week. A strong cold front crossing area waters late
Wednesday night into Thursday will bring moderate to strong offshore
flow to area waters for the rest of the work week. The onshore
flow over cooler waters over area bays and near shore waters will
create conditions conducive for advection fog. A Marine Fog
advisory has been issued for area bays and near shore waters
through Wednesday. A Small Craft Advisory may be needed at times
before the cold front's passage, and definitely after. /16 &&
