Snow Potential Index is up to 5 as we continue to try to figure out the Sat night-early Sun event. Uncertainty to how far southeast the snow band sets up -- odds of accumulation increase N & E. Very cold air to follow Sunday-early week.

We will NOT be issuing a snowfall forecast tonight (Thursday) for Sunday morning or sharing model maps -- which aren't reliable.
1) Any precip is still 50-60 hours away
2) Models have us on the edge of where accumulating snow may start/stop and small shifts could mean the difference between no snow and 3-4"
3) Temps may, at first, melt snow that falls, meaning less than what model maps are showing.
Bottom line: setup has very low predictability. Maps don't make sense right now.
The best forecast is "snow or a rain-snow mix likely early Sunday morning, with amounts, if any, uncertain. Stay tuned."
(Beware of what you hear, read or see elsewhere.)

DC running 8.5 degrees below average through the first 10 days of Dec and more cold ahead...

BUT a pattern change is increasingly likely before Christmas. Should lead to warmer temperatures by late next week or so. Could definitely last into the holiday if it takes hold. More at cwg.live.

Just what we were all hoping for: a December Sunday featuring meaningless football for the local team, and wind chills crashing through the teens, perhaps into the single digits by evening.

Here's the wind chill drop expected Sunday, as yet another Arctic blast arrives after whatever snow we end up getting in the early-morning hours. Wind chills probably remain in the teens and 20s on Monday as well.

Good news is, most signs are now pointing to a warmer 2nd half of the month. More on that to come!

There’s no business like SNOW business… ❄️

Here’s where things stand:

➡️ Friday:
Pretty much a non-event. Maybe a few flurries. If you really want a dusting, you’ll need to head toward central Virginia.

➡️ Early Sunday morning:
This one’s trickier — and lower confidence.
Yes, the Euro model is showing 3–4 inches for D.C. That’s not impossible, but several factors are working against a big result here:
• The broader pattern favors heavier snow to our northeast
• Temperatures above freezing when the precip arrives will cut into accumulation

Bottom line: A coating is more likely than a couple inches right now — but we still have a couple days to track it.

❄️ LET’S GO SNOW! ❄️

Colder air is back today. Highs in the 30s and wind chills in the 20s. Still watching two shots of snow - Friday and Sunday. Snow Potential Index is raised to 4 as we think Sunday could cause accumulation in the area.

Wednesday night snow thoughts:

• Friday’s snow chance is fading. Trends continue slipping in the wrong direction.
• Saturday night into Sunday is the one to watch. Signals are improving — but it’s still a tricky, low-confidence setup with lots of moving pieces.

We’re not going to whiplash you with every model run or chase every blip.

Slow, steady, and evidence-based — that’s how we roll.

Quick shower possible through early evening as a cold front passes.

Real fun is to the west. ❄️⛄🌬️

First blizzard warning of the season in the Alleghenies through Thursday morning. Up to a foot of snow and gusts to 50 mph. Details at cwg.live.

We're watching 2 snow chances now through the weekend. Here's our latest thinking after a thorough review of the latest model data:

Snow chance #1
🕒 Most like timing: Friday afternoon into night
💧 Moisture starved; could fizzle south/southwest of DC
❄️ Cold enough for all snow
🚗 Light road accumulation possible if snow falls after dark
📏 Accumulation potential: None to about 1 inch
👉 Our call for now: 10 to 20% chance of 1 inch of snow; 40% chance of at least a dusting

Snow chance #2
🕒 Most likely timing: Saturday night into Sunday morning
💧 A bit juicier than 1st system; heaviest precip could be N/NE of DC
🌡️ Could be warm enough to start as rain or sleet
📅 Possible impact on Sunday activities
📏 Accumulation potential: None to about 4 inches
👉 Our call for now: 30% chance (could trend higher) of at least 1 inch of snow

No temps in the teens this Wednesday morning, that's a win yes?!

Warmer 40s this afternoon aren't bad, but come with a rather gusty breeze.

Coming next:
📉 Trending colder into the weekend
❄️ Two chances for light snow
🥶 Arctic blast Sunday–Monday

Snow potential index — 3/10 (↑): Two shots at snowflakes, one Friday p.m. and the other Saturday night. Accumulation potential for each chance probably ranges from nothing to an inch or two.

What a sunset tonight (Tuesday)! 🌇🔥
A stunning sun pillar shot straight up from the horizon — making the whole sky look lit from within.

A sun pillar is a vertical shaft of light that forms when sunlight reflects off millions of flat, plate-shaped ice crystals floating in the air. They often appear near sunrise or sunset, and tonight’s was a beauty.

Thanks to Mindy Moretti for sharing this amazing capture on BlueSky!

Not enough cold for you so far? No problem.

As we discussed in a Facebook post earlier today (Tuesday), we have a couple of *uncertain* snow chances coming up later this week into the weekend. What is more *certain* is that Sunday through Monday looks VERY cold (maybe colder, probably windier than today).

Pictured are the high temperature forecasts for Sunday and Monday. Gusty winds should make it feel several degrees colder than the air temperature on Sunday. The winds may let up some by Monday.

The peak of the arctic blast? Sunday night into early Monday morning, when wind chills could be in the single digits.
