The atmosphere is basically cooked now with these training storms and BL overturning. So that will be running into a stable environment. It's got some strong effective bulk shear and helicity to work with, which may help with some organization, but I don't think that'll be able to overcome the stability. Lots more rain from it though across the LSV. Maybe some gusty 50mph winds with any outflow. With the ridge in the Atlantic and trough in the north central plains trending Debby to stay further west once it makes it's second landfall, I could see the CPA (along with CNY) taking the brunt of the rain. WPC has been shifting things slowly further west as well. This rain today certainly will not help with flooding concerns.

I wouldn't want to be an AT thru hiker in Virginia right now, I bet water sources are scarce

Solid storm with a tornado warning heading right up into Wellsboro

Those cells up in NW Clinton County are starting to get some good hooks on them

Was actually just talking to my buddy in Leesburg and were discussing the low water levels across much of northern VA. Dark red dots indicate <10% percentile of river/stream/creek gauge levels. Bright red indicate record lows for this date

The big heat out west will make it's way east over the rocky mountain area later this week and weekend. Both Laramie and Cheyenne WY will approach their all time record highs of 94° and 100° respectively, we'll see if afternoon clouds inhibit any attempt at breaking these records

Absolutely, double win here. Snow and cold, and the northern lights

I'm in northern Sweden for the month of March, took these yesterday!

Anyone know how much snow might be on the ground NW of Fort Collins around Greyrock Summit (Poudre Park)? Looking at hiking that Monday, but want to be sure trail conditions are decent enough and not like 2 feet of snow

10" on the measuring board in Fleetwood from my dad

Any Berks reports? Looks like that band meant business and affected much of eastern Berks as well. Might just have to wait for the folks to wake up and hear how much they got

Dad said we got about 9" in Fleetwood, biggest storm in quite some time. 2021 was the last double digit snow I even remember

Berks and Lehigh counties look to be in the best spot for this as of now. Probably start as some brief rain, unlike those in Carbon/Monroe counties. But the strongest banding and snowfall rates will slide through south of the Poconos for the longest duration. 6-10" thump in that area

Latest 12z GFS with yet another shift south. Sounding provided is for SE PA valid at 12z tomorrow morning. Fully saturated through the DGZ with maximum omega as well. It's going to thump around the morning commute, easily 1-2"+ rates for a time. Even though it's a quick moving storm, some places will see over 6" with rates that heavy for a time

Euro is quite a paint job for the Lehigh Valley

Dad said we got about 3.2" in Fleetwood. Happy for y'all further south towards Philly, its been a long time coming! Made me smile seeing Philly come in with 5"

NWS WWA for 2-4" seems right. Most will probably see 1.5-2.5". Max around 4 or perhaps 5+

We got down to -30° at the Laramie airport last night, the coldest temperature since January 2017 here when it got to -40. Driving around outside town in the Laramie Valley the car thermometer read -40°

Meanwhile out here in Siberia, I mean Laramie WY, the airport got down to -30° last night and driving around outside town my car read -40°. That's not wind chill, but actual air temperature! Certainly have never felt such cold air before in my life living in Pennsylvania

My folk said we got about 3.5" back in Fleetwood

NWS upgraded the NW burbs WWA to 3-5" on the latest forecast package. If the NAM is to be believed, there could be an iso 6"+ in there across Berks or the Lehigh Valley. Depends if we get some good banding to set up across that area, otherwise i don't think rates or snow growth will be spectacular. Snow comes in around 7-9pm, gone by 10-11am on the NAM. That's a solid 14-16 hours of snow. But, we won't be seeing consistent 1" hour rates or something.

0z ICON (yeah Icon i know) is really solid for NW burbs. 4-6" for all of Berks and the Lehigh Valley

GFS brings 1-3" back to the general Mount Holly CWA, those NW of 95. It's been clear looking at upper levels that were trending back towards a light advisory event. The 250mb jet continues to improve in orientation

We made it down to -15 in Laramie this morning, wind chill of -37. Expecting another 2-5" in town with the next few waves/impulses in the flow tonight and tomorrow night
