521 PM CST Mon Jan 8 2024

.KEY MESSAGES...

- Winter Storm Warning remains in effect for entire area starting
tonight at 6 PM lasting through early Wednesday morning. Heavy wet
snow, and blowing snow will lead to hazardous travel across the
area, especially later tonight through Tuesday evening.

- A couple embedded bouts/windows heavier snow bursts expected that
could lead of to over 1 inch an hour snowfall rates and rapid
accumulation.

- Additional chances for snow expected Wednesday night/early
Thursday and bigger system again Friday into the weekend with more
accumulation possible.

.SHORT TERM /THROUGH TUESDAY NIGHT/...
Issued at 315 PM CST Mon Jan 8 2024

The Storm...

A potentially high end winter storm warning still appears to be on
track, as sfc cyclogenesis is seen currently blossoming acrs the
TX/OK Panhandle region. Sfc pressure falls and kink in the gradient
fields show the way of sfc low propagation toward central to east
central IL by midday tomorrow. Ensemble low center depth at that
time is projected to be around 985 MB or a bit lower. Several system
lift mechanisms such as isentropic and F-gen are very impressive
tonight with stout warm air advection(WAA) surge, translating into
classic TROWAL fed Def Zone for secondary punch on Tuesday.

The WAA tonight will be fed by unseasonable precipital water
feed(PWATs) of 0.60 inches 150-200% of normal for this time of year.
Fcst soundings and comparing them to upstream trends suggest top-
down deepening saturation, with low to mid level saturation depths
up over H6 mb late tonight through at least late Tue morning,
including the -12 to -18C dendritic layer. The incoming amount of
lift by a closed off low pressure complex utilizing this saturation
depth by rule should wring out up to double the amounts of the PWAT
values, thus 0.60 goes to 1.2 inches of liquid equivalent. Most of
it probably being snow that translates into a foot with just base
10:1 LSRs, and that may be low with probably LSR`s varying from 10
to 12:1 along prime forcing/saturation swaths. THey will trend
higher to 13:1 or higher later in the event with in-wrapping cold
conveyor into departing def zone, but that will be past the time of
the occurrence of the heavy snow producing processes

Convective profiles later tonight on the soundings and cross-
sections show some slantwise/upright convective processes after
midnight into at least mid Tue morning acrs much of the CWA, as well
as MUCAPEs above the forced layer possibly to support some isolated
lightning discharges in robust friction filled snow columns. Thus
like the previous shift noted, that convective enhancement may make
for localized higher amount swaths. Snowfall rates will look to be 1-
2 inches an hour late tonight into Tue morning in the prime snow
bands with these kind of profiles, and would not be surprised if a
few areas experience 2-3 inch/hr rates for a few hours in the
optimum lift windows.

Conceptual prime forcing swath of the developing def zone on left
flank of the H7 mb low would suggest the heavy snow axis may lay out
from southwest of Ottumwa IA, to between IA City and the Quad
Cities, and to the Freeport IL area. This area not far off from the
prime conjunction of strong positive/upward omegas, -3 to -5C H85
temps, and 1000-H5 MB layer RH values of over 90-95% which lay out
generally along and west of the MS RVR and then lean into far NW IL.
The currently progged brisk omegas in these saturated profiles/cold
enough temps would point at snowfall amounts of 10-15 inches in the
prime swaths by Tue evening.

Snowfall Amounts: This event, if it pans out like projected would be
a once in a 10 or 12 year single snow storm event for the area.
After looking at a multitude of methods old and new(some listed
above), have gone with widespread 10-15 inches along and generally
west of a line from Keosauqua IA, to just east of the Quad Cities,
and to Freeport IL. 8-14 inches would be a general cover of most of
the CWA, except for a sharp gradient drop-off to 3-7 inches along
and southeast of a line from Carthage in west central IL, to
Monmouth IL, and to Princeton IL. These lesser areas may get more
rain-snow mix with bouts of WAA at times tonight, and a midnight
decrease or temporary dry slot as well if current storm track
verifies.

Winds: Mix out gusts in tightening pressure gradient on backside of
departing system look to be in the upper 30 KT range, thus 40-45 MPH
north to northwest gusts will complicate things with plenty of
drifting and some blowing. Depending on the consistency of the snow
pack and intensity of the lingering snow, can`t rule out near
blizzard or blizzard like conditions in rural/open areas late
Tuesday into Tuesday night. But that will have to be assessed for an
update in headlines as the finale of the event unfolds and
condition`s/visibility trends area noted tomorrow afternoon and
evening. Wind chills in the low teens to single digits by Wed morning.

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Issued at 315 PM CST Mon Jan 8 2024

Key Messages:

1. Below normal temperatures Wednesday through Monday.

2. Active pattern continues through the long term period with
several chances of snow Wednesday night through Monday.

Wednesday through Thursday:

Zonal (west to east) flow in in place across the CONUS to start the
period at 12 UTC on Wednesday as we sit in the base of a longwave
trough. Ridging is forecast to move quickly across the area during
the day with a relaxing pressure gradient across the area. Some
blowing and drifting will be ongoing on Wednesday morning but it
will become less widespread as the pressure gradient relaxes and
wind speeds come down.

A fast moving clipper system will move across the area Wednesday
night into Thursday morning. Temperatures will be cooler with lows
in the teens above zero. This will lead to snow to liquid ratios
across the area ranging from 10 to 15 to 1 across the area making it
a drier snow. The better lift and moisture will be along and north
of a Cedar Rapids to Clinton to Sterling Rock Falls line. Snowfall
amounts up to an inch are possible west of the Mississippi River
with 1 to 2 inches possible in Clinton, Jackson, Carroll, Whiteside
and Jo Daviess Counties. Subtle Shortwave ridging and quiet weather
will follow for the day on Thursday.

Thursday night into Saturday:

A digging 500 MB trough will move into the Plains Thursday night
into Friday. Currently, the 500 mb trough is forecast to transition
from a wave with neutral tilt to more of a negative tilt as it moves
into the Mid Mississippi Valley and then lift into southwest Ontario
by 12 UTC on Saturday. Overall this is a similar track to the
current storm system. Current model runs spread precipitation into
the area Thursday night and continuing into early Saturday morning.
Colder is forecast to move into the area later in the day on Friday
once the surface low passes leading to a high snow to liquid ratios.
There will also be a strong pressure gradient with this storm system
so it will be windy through the event with blowing snow possible
especially Friday into Saturday morning. Accumulating snow looks
like likely from this storm system.

Saturday night through Sunday night:

It will turn noticeably colder Saturday night into Sunday as high
pressure builds into the region. Low temperatures on Sunday morning
are forecast to range from 0 to -5*F. The coldest air of the year
will move into the area on Sunday and Monday. Temperatures at 850 MB
will be around -20*C resulting in high temperatures in the single
digits above zero. Low temperatures on Sunday night and Monday night
will drops in the single digits below zero area wide. Winds will be
breezy during this period. Currently wind chills are forecast to drop
into the teens below zero during this period but this will likely
change over the coming days.

Models have another clipper moving through the flow aloft and differ
in its location resulting in differences in the placement of
precipitation and snow across the area. The GFS and ECWMF track the
surface wave south of the area and keep the bulk of the
precipitation across Missouri while the Canadian brings it right
across the area.

&&

.AVIATION /00Z TAFS THROUGH 00Z TUESDAY/...
Issued at 515 PM CST Mon Jan 8 2024

Snow, mixed with a bit of rain at the front edge, is moving
north, and will impact all TAF sites around 00z. In the top-down
saturation under way, with CIGs going from MVFR to IFR the next
hour or two. Easterly sfc winds will continue to increase and
gust into the evening, then decrease a bit toward morning in
southern areas, but by afternoon, strong north winds are
expected in all areas. Wet snow will fall tonight through the
morning hours Tuesday. As the bouts of heavier snow move in
from the south mid to late evening, then another high snowfall
rate(1-2" an hour) from 3 am through 10-11 am Tuesday at most
sites producing LIFR conditions and quick snow accums on the
runways. These LIFR conditions may linger through the day along
and north of Interstate 80, while seeing a bit of improvement in
the south. By mid afternoon, as winds increase from the north,
blowing snow and falling snow will create another period of LIFR
conditions that will last through Tuesday night.

I’m not saying the snowless streak will go on that long. For the record I think the snowlessness is a combo of bad cycle and warming. We likely get a somewhat better period at some point even with warming. 
 

But let’s say it doesn’t improve. What if we continue at the same snowfall rate we’ve had on avg the last 8 years where DC is averaging about what Charlotte NC or Spartanburg SC should!  How long do you think before those denying the climate has changed come around?  2 more years?  5 more years?  Are we in 2040 and it’s been 25 years since Baltimore had a 6” snow and they’re still saying it’s just bad luck and we will turn it around any day now?

If memory serves we're the same age...so same! I am even more thankful for those winters now. They are certainly more precious given how much uncertainty we have about our future snows. What an epic period from 2010-2016!

I don’t want to go too far down this rabbit hole, but I think our current 7 year winter suckage is a combo of background warming, natural cycles that are unfavorable, and bad luck. We’ve had troughs favoring the west in winter for years now, but up until winter 16-17 it was the opposite with a seemingly permanent ridge out west. Remember the “ridiculously resilient ridge” out west? Sucked for them but we loved it. That cycle flipped HARD. I think that switch will flip again at some point to favor a trough in the east in winter, but background warming will probably mean it’s not as productive as it would have been in the previous cycle.

i think people definitely underestimate luck and the little minutiae that go into every storm. NYC south needs luck to snow more than like 1-3". it's a significant component given that so much can go wrong. we seem to have run out for the last year and change, but it will be back

Right now just to get 1” we need fantastic luck, straight arctic air, the entire continent covered in feet of snow, a -9SD NAO/AO combo, joined -EPO/+PNA ridge from Costa Rica to Siberia…

I lived in Tinton Falls/ Mon County for 30 years. Born in Long Branch at Mon Medical.  My Ex grandparents live in Whiting. 

People seem way too enthusiastic in the LR thread over next Tuesday's rainstorm. I am just not seeing much of anything other than a brief cool down followed by more cutters.

It wasn't like this a decade ago. Seemed like every other night we were getting clippers and light snowfall.

Things have been really strange. It just doesn't want to snow. Even when it has snowed here in the last decade its very non stick. Haven't had a plow in here since the BLizzard of 2016.

2016 sucked lol. We had 4 days of cold. A freak snow that melted 36 hours later with temps in the 60's. That was it for that winter. Sure.. better then the garbage lately, but hardly a good winter. 2014-15 was the last winter we had basically. 

15-16 was way better in SoMD than 14-15. We had another WSW on President's Day (some areas got more from that than the HECS), then another borderline WSW event in early March, and even an accumulating event in April. 14-15 was only really good if you were in the northern tier.

Of course both winters look amazing compared to the last two years here, so I'd take either of them at this point LOL

1972-1977

we have seen the best of DMV winters. I will take what we have seen over any generation except for maybe the 60s

 

I have referenced that period in the 1950's as the closest comp to this...but pointed out this is worse, and I think that's where warming comes in.  

That period you referenced BWI averaged 13.3" with a median of 14.1.  The last 7 years BWI has averaged 9.9" with a median of 10.9.  Both were comparably bad periods and similar to the averages of those periods if you normalize for warming and our lower snow averages now but that just proves my point.  

The stats are similar for DC.

That period in 49-57 avg snow was 10.9" with a 10.2 median.  Now DC's avg since 2016 is 6.8" with a median of 5.4.  This is worse.  

But what is really scary is that every previous snow drought that was somewhat close to this was bookended by epic snowfall periods.  For example that period you referenced in the 50's was preceded by 8/9 years above 20" and followed by 4/5 years above 30".  So, unless we go on an absolute snow heater VERY SOON...things will start to become absolutely unprecedented with no previous period that comes even close in comparison.  

You are right at this moment there are a couple previous periods that while not as bad are close enough that you could make the argument its just random.  But if this drought continues a couple more years that argument becomes impossible.

2016 sucked lol. We had 4 days of cold. A freak snow that melted 36 hours later with temps in the 60's. That was it for that winter. Sure.. better then the garbage lately, but hardly a good winter. 2014-15 was the last winter we had basically.

15-16 was way better in SoMD than 14-15. We had another WSW on President's Day (some areas got more from that than the HECS), then another borderline WSW event in early March, and even an accumulating event in April. 14-15 was only really good if you were in the northern tier.

Of course both winters look amazing compared to the last two years here, so I'd take either of them at this point LOL

We didn’t have any big snows outside of Snowzilla in ‘16, but I do have a couple inches in my records from Feb 15 (looks like it stuck to all surfaces) and several snow showers/icing events. I was living in Bethesda at the time, so there might have been more further nw.
