We will see a repeat of 2013-2014 and I will finally be declared SUPREME LEADER er... WINNER of the snowfall contest! @PrinceFrederickWx I'll be waiting for you with my prize in the spring... ... DON'T BE LATE!

Meteorological (or Climatological ) Winter is upon us!

The Great Mid-Atlantic Arctic Severe Squall Event of 2020 Note: Tornadoes were not at their peak intensity along their whole path as the tornado path lines may falsely imply.

So... nobody's going to talk about the GFS parallel giving us our December 5th snow event?

Finally a flush hit for you... In all seriousness I hope the damage isn't too bad there.

Awesome! Are you getting much rain?

SEL1 URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 511 NWS Storm Prediction Center Norman OK 530 PM EST Sun Nov 15 2020 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of District Of Columbia Delaware Central and eastern Maryland New Jersey Southeastern Pennsylvania Northeastern Virginia Coastal Waters * Effective this Sunday afternoon and evening from 530 PM until 1100 PM EST. THUNDERSTORM WIND GUSTS TO 70 MPH...and DANGEROUS LIGHTNING ARE POSSIBLE IN THESE AREAS. The severe thunderstorm watch area is approximately along and 65 statute miles east and west of a line from 25 miles north northeast of Allentown PA to 50 miles southeast of Washington DC. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU1). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes.

STW now out.

Hmmm... Dulles is up to 70F now which is higher than CAMs had the temperature reaching. The dewpoint is a little bit low though at 57F.

We've been Slighted in much of the region east of the mountains. ..LOWER GREAT LAKES TO MID-ATLANTIC/NORTHEAST SCATTERED THUNDERSTORMS ARE ONGOING ACROSS SOUTHEAST LOWER MI INTO WESTERN OH WITH A HISTORY OF WIDESPREAD STRONG TO ISOLATED SEVERE WIND GUSTS. THIS INITIAL ACTIVITY MAY STRUGGLE TO FURTHER INTENSIFY OWING TO BOUNDARY-LAYER DEW POINTS IN THE LOWER 50S WITHIN A NARROW SPATIAL CORRIDOR AHEAD OF THIS CONVECTION. IT SHOULD EVENTUALLY OUTPACE THIS NARROW WEDGE OF SURFACE-BASED INSTABILITY AS IT SPREADS EAST/NORTH OF LAKE ERIE LATER THIS AFTERNOON. A MORE PRONOUNCED SQUALL LINE IS EXPECTED TO DEVELOP AROUND 21-23Z FROM CENTRAL NY TO CENTRAL VA AND SWEEP EAST-NORTHEAST ACROSS THE NORTHEAST AND NEW ENGLAND COAST THROUGH EARLY TONIGHT WITHIN AN INTENSE SHEAR/MINIMALLY BUOYANT ENVIRONMENT. THIS SQUALL SHOULD DEVELOP AS THE ROBUST COLD FRONT IMPINGES ON LOW-LEVEL MOISTURE ADVECTING NORTH FROM THE CAROLINAS/SOUTH ATLANTIC COAST. BETWEEN 00-03Z, MID 50S BOUNDARY-LAYER DEW POINTS SHOULD REACH AS FAR NORTH AS EASTERN PA INTO SOUTHERN NEW ENGLAND ALONG THE TRACK OF SECONDARY CYCLOGENESIS. WHILE LOW-LEVEL LAPSE RATES WILL PROBABLY REMAIN WEAKER RELATIVE TO THE LOWER GREAT LAKES REGION, THE COMPARATIVELY RICHER LOW-LEVEL MOISTURE SHOULD COMPENSATE. IT IS PLAUSIBLE THAT LIGHTNING GENERATION MAY BE CONFINED TO AREAS FARTHER NORTH AMID SCANT ELEVATED BUOYANCY AND GREATER LARGE-SCALE ASCENT. NEVERTHELESS, THE PRESENCE OF A LOW-TOPPED SQUALL LINE AMID 50-60 KT 925-MB WINDS SUGGEST STRONG TO SEVERE WIND GUSTS ARE POSSIBLE EVEN IN THE ABSENCE OF LIGHTNING. AS SUCH, THIS REGION HAS BEEN UPGRADED TO SLIGHT RISK. ..GRAMS/DEAN.. 11/15/2020

Yeah. Just wait until February... and also, prior to that, mid/late December.

Why 33 and rain when you can 32.000000001 and rain!

You're nexting sleet in October?

It'sa comin.

I remember that day as well. I remember some heavy showers throughout the day w/ breezy conditions. I remember getting home from school in Herndon hust after 2:30pm and being surprised that the main line was already right on my doorstep. Looking back at that thread I remember lots on here being surprised at how early the main line arrived as well. There were brief torrential rains and wind gusts into the 30s (mph) here from the line. I noticed no thunder/lightning at all from it. I too was surprised to see looking back at SPC archives for that event a few years later that we had been placed under a MDT risk for wind (45% non-hatched). That would just be a high-end ENH risk the way that SPC works today. I remember the lack of tornado warnings as well despite being in a 10% non-hatched tor risk. The September 8th, 2012 event ten days prior, on the other hand, was a lot more impressive in the region with a lot of minor wind damage. I got wind gusts of 50+ mph in my neighborhood from that event. The funny thing is that the line from that event seemed more impressive down here than it did up the urban corridor where there was an actual MDT risk in the place... save for the Long Island tornadoes that day. As a whole though, that September was definitely a bit more exciting than usual severe weather-wise.
