PM Update: Shower threat through evening
Sunshine returns on Friday, lasts through Saturday

Showers -- with some rumbles of thunder and brief heavy rain -- are affecting the area this afternoon. Northern and eastern sections are now in on the action after precipitation mainly hit the western suburbs through early afternoon. Additional activity along a cold front, still approaching from the west, will threaten through evening. Highs topped out in the upper 50s and low 60s -- some locations have cooled back a bit with the rain.

Through Tonight: We stick with a risk of showers -- a few heavy with rumbles of thunder -- through the evening and there could still be a few sprinkles after midnight. Clouds should be breaking by sunrise if not before. Watch for some areas of fog overnight. Lows range from the mid-40s to near 50.
Tomorrow (Friday): Looks like we'll end the week on a nice note Friday as sunshine returns. There could be some remnant morning cloudiness, otherwise it's mostly sunny with a northwest breeze around 10 mph. Temperatures again rise to highs right around 60.

Eggo shortage: Kellog Co. blamed a nationwide shortage of frozen waffles on the historic flooding that hit Atlanta in late September. Though the plant was initially closed to sanitize after inspectors found Listeria in the facility, heavy rains delayed the process further. Interestingly enough, Kellog left out the Listeria part from it's official FAQ posted to their Web site, saying flooding was the reason for the shortage. Easier to blame nature than admit fault?

Sorry for the repeat, but I posted this in the morning thread just as the PM Update came out: So, I'm leaving this Saturday to spend Thanksgiving in Hatteras, NC. NWS mentioned last night in the long-range discussion the possibility of a Miller Type B forming late Sunday into Monday and working its way up the coast. I know it is way too far out for specifics, but does CWG care to speculate? That area got destroyed by the Ida remnants, and NC-12 just reopened yesterday. Any chance for a faster moving repeat?

This is not a cold front per se approaching, but what is called an occluded front, where the warm air mass is trapped between two colder air masses at the surface and lifted completely off the ground.....hence the embedded thunderstorms (and convection) are elevated in nature rather than at the surface. There were some pretty good ones late this morning west of here.........with some reports of pea-sized hail aong the Blue Ridge. In this case, the occluded front, at the surface, separates a cool marine layer with NE winds ahead of it from a cool, drier NW flow behind it. Hopefully we'll break out of this mess later tonight and get into the dry NW flow.

LOTS of wet leaves on the road, be careful on sharp turns and exit ramps like the GW Pky

Bombo, you are technically correct about it being an occluded front. For the purposes of a public forecast a cold front does the same thing though.

Quite an intense little storm rolling through DC. Had a few close lightning strikes.

How unusual is it for the DC area to get this kind of thunderstorm so late in the year?

More thunder and moderate to heavy rains on the edge of Takoma Park.

@spacecadetkid
It's not that unusual... we get thunderstorms every month of the year, though they're certainly less common in months spanning November-March...

I can't even remember that last time I heard thunder in the DC area.

Some pretty intense thunder and lightning in Calverton. Rain's coming down in buckets too.

Out west, we got our rain earlier in the day. I'll post a total tomorrow morning.
If interested, I wrote a brief blog post on measuring rain. Are buckets good enough?

Latest IAD RAOB more like a thunderstorm setup:
Lifted Index: -1.4
Total Totals Index: 53 [good thunderstorm ratio]
CAPE: 201 J/kg. [Now triple-digit; atmosphere more juiced-up, but not quite "severe" category.]
K Index: 34 [still around 50-60% chance?]
Precipitable Water: 2.62" [lots of moisture to work with]
Cell movement: 239 degrees @ 28 kts. [SW-NE].
Reminds me a bit of summertime occluded/cold front setups in the Upper Midwest.
Outlook is good [for a change] re tomorrow night's big dance, but rather wet early next week.
Tom Skilling promises us a major Arctic outbreak aoa Thanksgiving Day. Otherwise conditions are far too mild El Nino around here.

BTW: Interesting Eggo situation, the Listeria notwithstanding...but the Baileys Crossroads Giant has Unique Belgique Belgian waffles which can be microwaved [Eggo requires a toaster!] and no Listeria.
