...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
SOUTHERN ALABAMA...SOUTHWEST GEORGIA...AND THE FLORIDA PANHANDLE....
...SUMMARY...
Severe thunderstorms are possible across portions of the Southeast
states this afternoon. Damaging gusts and a few tornadoes are the
main concerns.
...AL/GA/FL...
Morning water vapor imagery shows a potent mid-level shortwave
trough and associated 100kt jet over AR. This feature will track
rapidly eastward across the TN Valley today, with large scale
forcing overspreading the Gulf Coast states. This will aid in the
development of robust thunderstorms along the cold front now
extending from central AL into southeast LA. Ahead of the front,
southerly surface winds will transport Gulf moisture northward and
result in weak but sufficient destabilization for a risk of a few
severe storms. Vertical shear profiles will be favorable for a few
tornadoes if semi-discrete structures can form along/ahead of the
developing QLCS. Otherwise, locally damaging wind gusts are the
main concern. Refer to MCD #0057 for further details.

MD 0054 CONCERNING HEAVY SNOW FOR PENNSYLVANIA...NEW JERSEY...NORTHERN WEST VIRGINIA...NORTHERN VIRGINIA...NORTHERN DELAWARE...NEW JERSEY...FAR SOUTHEAST NEW YORK
Mesoscale Discussion 0054
NWS Storm Prediction Center Norman OK
0501 AM CST Sun Jan 25 2026
Areas affected...Pennsylvania...New Jersey...Northern West
Virginia...Northern Virginia...Northern Delaware...New Jersey...Far
Southeast New York
Concerning...Heavy snow
Valid 251101Z - 251700Z
SUMMARY...Heavy snowfall, with rates of around 1 inch per hour, is
expected to continue to develop from parts of the upper Ohio Valley
eastward to the Mid-Atlantic this morning.
DISCUSSION...The latest mosaic radar imagery shows widespread
snowfall ongoing from the Ohio Valley eastward into the
Mid-Atlantic. This is occurring along a broad zone of strong
isentropic ascent, aided by warm advection associated with a 50 to
60 knot low-level speed max over the southern Appalachians. The exit
region of this feature will continue to move northward this morning
into the upper Ohio Valley and northern Mid-Atlantic, helping to
gradually intensify snowfall rates. This will result in areas of
heavy snow from Pennsylvania and northern Virginia eastward to New
Jersey and far southeastern New York. Snowfall rates of 1 inch per
hour will be possible within the more well-defined bands that setup.
The heavy snowfall potential from Pennsylvania and New Jersey
northward should continue through the mid to late morning. In
northern Virginia, Maryland and Delaware, a changeover to freezing
rain is expected by late morning.

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS SOUTHERN
AL...SOUTHWEST GA...AND THE FL PANHANDLE...
...SUMMARY...
Severe thunderstorms are possible across portions of the Southeast
states this morning and afternoon. Damaging gusts and a few
tornadoes are the main concerns.
...Portions of the Southeast States...
Early-morning satellite imagery shows a southern-stream shortwave
trough moving across the southern Plains and into the more
single-stream confluent flow across the eastern CONUS. Surface
analysis places the low associated with this shortwave over the
central MS/AL border vicinity. A cold front extends from this low
southwestward through southeast LA and into the western Gulf.
Combination of these features compose the large winter storm system
that is impacting much of the central and eastern CONUS.
Recent regional radar imagery and surface observations reveal an
extensive area of anafrontal showers and thunderstorms from east TX
into MS and TN Valley. Much of this precipitation is falling as
either freezing rain or sleet, with sporadic lightning accompanying
this winter precipitation across east TX, northern/central LA, and
western/northwestern MS. Currently, the warm sector, which extends
from southeast LA across southern AL and southern MS into the FL
Panhandle, is free of any thunderstorms. This is expected to change
throughout the morning as continued moisture advection further
modifies the airmass and modest buoyancy develops ahead of the
advancing cold front. Despite the fast progression of the cold
front, strong deep-layer vertical shear should allow for the
maintenance of deep convection along the frontal zone once it begins
to encounter the modest buoyancy. Additionally, the strong vertical
shear should also allow for some organization/rotation within any
deeper, more persistent updrafts.
Damaging gusts appear to be the primary severe risk, with the risk
concentrated from southern AL and the western FL Panhandle into
southwest GA and the central FL Panhandle where the best
thermodynamics (i.e. 500-1000 J/kg of MLCAPE) are forecast.
Low-level shear is strong enough to support a tornado risk in this
area as well, with the linear nature of the convection favoring
brief cell-in-line/QLCS circulations (in contrast to a more
discrete, supercellular mode). A few discrete cells ahead of the
line cannot be entirely ruled out. However, limited residence time
due to the fast-moving front and likely shallow character due to
limited buoyancy should prevent these updrafts from maturing.

MD 0052 CONCERNING WINTER MIXED PRECIPITATION FOR NORTHERN SOUTH CAROLINA...CENTRAL AND NORTHERN NORTH CAROLINA...SOUTHERN VIRGINIA
Mesoscale Discussion 0052
NWS Storm Prediction Center Norman OK
0120 AM CST Sun Jan 25 2026
Areas affected...Northern South Carolina...Central and Northern
North Carolina...Southern Virginia
Concerning...Winter mixed precipitation
Valid 250720Z - 251315Z
SUMMARY...Areas of freezing rain are expected through Sunday morning
from South Carolina into southern and central North Carolina. From
northern North Carolina into southern Virginia, a mix of snow and
sleet is expected to changeover to a mix of sleet and freezing rain
by daybreak.
DISCUSSION...Latest water vapor imagery shows abundant mid-level
moisture across most of the east-central U.S. within
west-southwesterly flow aloft. A broad mid-level jet extends
westward from the Northeast into the southern Great Lakes and Ohio
Valley. Strong lift within the right entrance region of the jet
combined with a broad zone of warm advection will continue to be
favorable for widespread precipitation from the Ohio and Tennessee
Valley eastward to the Eastern Seaboard. From the Carolinas
northward, a sub-freezing airmass is in place but temperatures in
the low to mid-levels are warm, with forecast soundings showing a
warm nose just above 850 mb ranging from +5 To +10 C. This
temperature profile will be favorable for freezing rain from South
Carolina northward into southern and central North Carolina through
daybreak.
Further to the north across northern North Carolina and southern
Virginia, low to mid-level temperatures are cold enough for a mix of
snow and sleet. As strong warm advection continues over the next few
hours, a gradual transition to sleet and freezing rain is expected.

MD 0053 CONCERNING WINTER MIXED PRECIPITATION FOR FAR NORTHERN MS...WESTERN/MIDDLE TN...SOUTHWEST KY
Mesoscale Discussion 0053
NWS Storm Prediction Center Norman OK
0123 AM CST Sun Jan 25 2026
Areas affected...Far Northern MS...Western/Middle TN...Southwest KY
Concerning...Winter mixed precipitation
Valid 250723Z - 251130Z
SUMMARY...Mixed winter precipitation is expected to continue for at
least the next several hours from northern MS across western/middle
TN and into southwest KY for the next several hours. Freezing rain
rates over 0.03"/hour are possible.
DISCUSSION...Regional radar imagery has shown a notable increase in
reflectivity across western TN over the past half hour. Based on
radar data from KNQA, this area of increased reflectivity is
occurring between 3000 and 4000 ft, which is near where refreezing
into sleet would occur based on area forecast soundings.
Consequently, this increased reflectivity is likely more related to
bright band effects than increasing precipitation rates, while also
indicating where the transition zone from freezing rain to sleet is
currently located.
Expectation is for this transition zone to drift
northward/northwestward over the next few hours as the warm nose
increases slightly amid continued warm-air advection. This warm-air
advection will also foster continued precipitation, confirmed by
regional radar imagery showing widespread upstream precipitation.
All of these factors suggest that mixed winter precipitation will
continue from northern MS across western/middle TN and into
southwest KY for the next several hours. Freezing rain rates up to
0.03"/hr. have already been observed at BNA, with similar (and
higher) rates possible over the next few hours, particularly over
western TN.

Severe weather concerns are negligible for the extended forecast

flow out of southern Canada will replenish a cold, dry and stable
air mass underneath Arctic high Pressure. While some surface
cyclogenesis appears possible over the eastern Gulf and Atlantic

MD 0051 CONCERNING HEAVY SNOW FOR SOUTHERN ILLINOIS INTO SOUTHERN INDIANA AND SOUTHWEST OHIO
Mesoscale Discussion 0051
NWS Storm Prediction Center Norman OK
1100 PM CST Sat Jan 24 2026
Areas affected...Southern Illinois into southern Indiana and
southwest Ohio
Concerning...Heavy snow
Valid 250500Z - 251100Z
SUMMARY...Heavy snow band development is anticipated through the
next several hours across portions of the Ohio River Valley.
Snowfall rates exceeding 1 inch/hour appear probable later tonight.
DISCUSSION...A broad band of heavier precipitation is beginning to
emerge from northern AR into the lower OH Valley per regional radar
mosaics over the past 1-2 hours. This comes amid strengthening
frontogenesis through a deep layer (925-700 mb per recent
mesoanalyses) as the primary upper wave begins to migrate eastward
into the southern Plains. Latest forecast guidance shows
intensifying frontogenesis across the lower MS Valley into the OH
Valley through 09-12 UTC, which will support further
organization/intensification of a focused mesoscale precipitation
band. With mid-level temperatures below freezing north of the OH
River, snow should remain the predominant precipitation type.
Moderate snowfall rates will be common with a focused corridor of
higher rates (in excess of 1 inch/hour) likely. Per recent ensemble
guidance, this corridor will most likely emerge across southern IL
into southern IN and southwest OH.
These solutions also depict optimal banding potential during the
09-12 UTC period later tonight into early Sunday morning. However,
recent ASOS/AWOS observations from southern IL and southern IN have
shown an uptick in snowfall intensity (denoted by reduced
visibilities to 1/2 mile or less) over the past hour. These trends
suggest that the onset of heavier snowfall rates may commence
earlier than currently anticipated by most guidance as intermittent
moderate to heavy snow bands becomes more prominent with time.
