...New MESOSCALE UPDATE...

.MESOSCALE UPDATE...

Issued at 453 PM CDT Sun Mar 12 2023

Strong to severe thunderstorms remain possible across southeastern
MS into southwestern AL and the FL panhandle this evening. Several
supercell thunderstorms have developed over the past hour across
south-central MS with large hail being the primary hazard. KMOB
and KDGX VWP's continue to exhibit long, straight hodographs above
1km AGL with muted low level curvature. As mentioned earlier, this
hodograph shape with strong mid-level shear supports hail growth
and hail production in splitting supercells. This is particularly
the case considering these thunderstorms remain elevated with
around 1,000 to 1,500j/kg of MUCAPE. There does appear to be a
MUCAPE gradient oriented northwest to southeast over southwestern
AL, which is evident from radar imagery of a recent storm
weakening after moving into Clarke and Monroe Counties. Unless
some airmass modification occurs over the next couple hours, this
would suggest the better severe threat will remain to the west
across southern Choctaw County southward into Mobile/Baldwin
Counties, and points west into our southeastern MS Counties. As
the shortwave and associated surface cold front continues to push
east into the early to mid evening hours, expect coverage of
discrete to semi- discrete supercells and multi-cell clusters to
continue to increase and for storm intensity to increase as well
until MUCAPE values diminish in the hours following sunset.

In summary, strong to severe thunderstorms with the threat for
large hail upwards of golf ball size remains possible across
portions of southeastern MS into southwestern AL, and perhaps the
FL panhandle through early to mid evening. MM/25

.PREV DISCUSSION... /issued 357 PM CDT Sun Mar 12 2023/

..New NEAR TERM, SHORT TERM, LONG TERM, MARINE...

NEAR TERM...
(Now through Monday)
Issued at 244 PM CDT Sun Mar 12 2023

Showers and storms will continue to slide east across the area
through the mid evening hours for inland communities. Further to the
south (closer to the coast), showers and storms will continue to
develop and progress east through much of the evening. The HRRR has
the best handle on this afternoon's convection and continues to show
redevelopment across the coastal counties and Gulf waters well into
the pre-dawn hours on Monday. As we head into the overnight and
early morning hours, the main concern will switch from hail to
nuisance flooding as showers and storms repeatedly moves over the
same locations along the coastline. Only expecting another inch or
so of rain overnight along the coast, but this may be problematic
given the heavy rainfall that has already fallen today and the
saturated soils (especially for locations south of I-10).

A surface high begins to build into the region in the wake of the
cold front tonight and Monday. Subsequently, northerly winds will
usher in much drier air to inland communities overnight with PWATs
falling below a half inch. Cold air advection sets up after midnight
and temperatures steadily fall into the 40s across inland
communities while remaining in the 50s along the coast/beaches.
Temperatures will struggle on Monday in this pattern with highs only
rebounding into the low 60s inland with upper 60s at the beaches.

Spring Break Note: The HIGH RISK OF RIP CURRENTS remains in effect
through tonight for coastal Alabama and northwest Florida beaches
with surf remaining around 3-4 feet. The risk subsides to MODERATE
on Monday as northerly winds persist at the beaches. 07/mb

SHORT TERM...
(Monday night through Wednesday night)
Issued at 244 PM CDT Sun Mar 12 2023

An upper level northwest flow will dominate through the period
with surface high pressure building into the area. This will
maintain dry and cool conditions with precipitable water values of
0.5 inches or less as northerly winds advect cooler and drier air
into the region. This pattern will keep temperatures below
seasonal norms for this time of year. Lows Monday night will range
from the mid and upper 30s inland to mid 40s near the coast.
Tuesday night will feature the coldest temps with lows in the low
to mid 30s inland to mid 40s near the coast. Temps will be very
close to freezing over far northern areas which we will continue
to monitor for a possible freeze watch due to the warm conditions
we have experienced recently. Highs on Tuesday will only be in the
upper 50s and low 60s inland to low 60s near the coast. Wednesday
will be slightly warmer, in the low to mid 60s across the area.
/13

LONG TERM...
(Thursday through Sunday)
Issued at 244 PM CDT Sun Mar 12 2023

Surface high pressure will move east of the area on Thursday with
a southerly flow developing. Meanwhile upper ridging will build
over the area as an upper trough digs across the southwestern
states. This will allow moisture to increase ahead of an
approaching cold front. This front is expected to bring the next
chance of showers and storms to the area on Friday into Saturday.
Highs on Thursday and Friday will warm into the low to mid 70s
with another shot of cooler and drier air moving into the region
behind the front. /13

MARINE...
Issued at 244 PM CDT Sun Mar 12 2022

A moderate to strong onshore flow persists over the nearshore
and offshore coastal waters this afternoon as an outflow boundary
sits along the coast. Offshore flow will set-up later this
afternoon into this evening as a cold front dives south into the
marine area. Moderate to strong offshore flow will continue
through the early part of the week before subsiding by midweek. A
light to moderate onshore flow is expected to redevelop late in
the week with a gradual increase in winds by Friday. SCA
conditions persist over most of the marine area through Monday
morning. 07/mb
