That game was a disaster. You were up 5-1. How do you fooking lose that game? This team has serious 3rd period problems

My sister has been going nuts the whole 4th quarter lol

So just so I get it right... mentioning Gwen or Superman 4 is ban-worthy?

Can we take the 18z RAP?

I'll take my 1-2" and call it a day from the 18z GFS

Seems the "death band" is a bit earlier... now more around 09z

Appalachians, precipitation will struggle to make progress to the east of the Allegheny Front for several hours. As the wave amplifies and approaches from the west, most models show a jet steak developing downstream, with forcing for ascent increasing within the equatorward entrance of the jet streak. Most solutions show the jet entrance region lining up right along I-95. Ascent within the jet entrance region may cause precipitation to jump eastward and develop in-situ along the I-95 corridor, largely skipping locations between the Allegheny Front and Blue Ridge. Precipitation within the jet entrance region to the east of the Blue Ridge is expected to blossom during the mid-late evening hours, and then slowly drift southeastward through the remainder of the night. The precipitation may begin as a brief period of rain or mixed rain and snow, especially along and southeast of the I-95 corridor. This mix should be short-lived however, as much colder air rushes in behind an Arctic front that will move through over the course of the night. In terms of timing, some light precipitation could begin as early as the mid-late evening hours, but the bulk of the precipitation along the I-95 corridor is expected to occur between roughly 11 PM and 7 AM. The band that will develop will be a relatively narrow feature, and will feature moderate to heavy snow at times. Snowfall rates within the band could near or potentially briefly exceed one inch per hour at times late Saturday night. With a narrow feature producing heavy precipitation, snow totals will be heavily dependent on the ultimate placement of this band. This, combined with the potential for a bit of mixing with rain at onset makes for a challenging snowfall forecast. Probabilistically speaking, 12z guidance has focused in on the I-95 corridor from DC northeastward, and then eastward along US-50 toward the Chesapeake, with northeast Maryland southward toward Annapolis having the greatest probabilities for higher totals. As of this moment, a broad 1-4 inches from the vicinity of the I-95 corridor eastward appears like the most likely scenario, with embedded maxes of 4-7 inches possible where the band resides for the longest time period. Since there will be very sharp snowfall gradients on the edges of this band, and there`s still a bit of uncertainty with respect to where this band will be, we`ve decided to hold off on issuing headlines to the east of the Blue Ridge for the time being. Headlines will almost certainly be needed eventually, and we`ll continue to assess trends and refine the forecast through the remainder of the day. Snow will end from northwest to southeast a few hours either side of daybreak, with the back edge of the snow clearing southern Maryland by around mid-morning. Strong cold air advection is expected behind the Arctic front through the day Sunday, with 850 hPa temperatures crashing to around -15 to -20 C by peak heating. This will cause temperatures to drop through the 20s over the course of the day. Northwesterly wind gusts to around 35 mph will make it feel even colder, pushing wind chills into the single digits and teens. After the snow moves out, dry conditions are expected to the east of the mountains. Upslope snow showers will linger in the Alleghenies over the course of the day. Cold and windy conditions will continue through Sunday night, with cold weather headlines likely being needed for portions of the area. &&
