What are the changes? Not as big a threat?

Sorry just got back here. I meant chances - it’ll storm but I don’t see guest severe with hail. Tomorrow is a better chance.

96 at the house. Car reads 98 here in camp hill.  

Had a 2 hour outdoor event at 3. I’m wiped out. It is nasty out.

Looks like a nice line of storms out west per radar. Their arrival after 8pm might steal some of their thunder (pun intended) though.

In a severe warning. It’s not a severe storm. 

But spotty heavy rain (comes and goes) and fairly gusty winds (low 30s). 

[Storm Clouds]

Man what the heck…the mountains ate that line!

Total bust in Marysville this time. Just some gusty winds & light rain, barely a Trace.

How did this miss?

Loss of heating / sun and mountain uplift. Happens all the time.

Wind with .10 rain from the storm. Seems like they fell apart. Anyway we have tomorrow. Let's see if tomorrow produces anything.

Yeah, it was a joke here. Three rumbles of thunder, an 8.4 mph wind gust, and, like you, 0.10" of rain.

71 for the low again.
04” of rain yesterday. As soon as it hit cars or pavement it dried right up.

Last 2 storms not much rain at all.

[mahantango#1]

Looks like most places won't see any rain today.

It seemed like all the storms yesterday at issues reading inflow from the rain core and essentially would choke themselves while the area around them played roulette with who is going to get to convergence from the competing outflow boundaries and who was going to get left in the dust. If you look at what happens when the storms congeal consolidate into a cold pool that cold pool axis pretty much a shovel throwing up all the warm moist air quickly upwards and technically that is what propagating it they original storms pretty much blow up die off while the cold pool constantly is pushing the warm moisture ahead giving the illusion of the storms actually moving. Yeah there is definitely a gradient to all this.

Heading up today to Montreal and Mont Tremblant, to apparently experience the April we never had here. And actually have to be faster days I will take that in the heart beat.

After playing around with a bunch of different styles I think I've settled on this one for the perfect style for vacation weather sending out to everyone in the extended family who's going up there.

Montreal is an amazing city. Quebec itself is gorgeous. Enjoy

After a mainly clear and mild Saturday night, winds will turn southerly Sunday morning and bring more humid air back into the region. Another cold front will sweep through the Commonwealth from Sunday afternoon into Sunday night, interact with the very warm and unstable air mass in place, and spark widespread showers and thunderstorms. The upper-level energy supporting Sunday's front will also be much more vigorous and organized than this afternoon's and on a southwest-to-northeast trajectory across the region. Meanwhile, winds in the mid- and upper-levels of the atmosphere will generally be westerly, so there will be sufficient, deep-layer directional and speed wind shear for tornado formation. I don't expect a tornado outbreak or major, long-track tornadoes, but a few to several twisters are a real possibility in northern MD, southeastern PA, and the Lower Susquehanna Valley. In addition, the most intense storms will likely contain damaging wind gusts up to 65 mph, quarter-sized hail, frequent lightning, and localized flash flooding. The atmosphere will be sufficiently moist and unstable with temperatures and dewpoints in the 80s and mid-to-upper 60s, respectively, for rapid thunderstorm development and growth. As such, rainfall rates may easily reach 2" per hour in many of the storms, but rainfall amounts will vary greatly from neighborhood-to-neighborhood and county-to-county. They may "average" around 0.50" for the region, but some "jackpot" locations may receive up to 2.0-2.5". Regardless, I expect widespread incidents of downed trees and power lines, roof and vehicle damage, and perhaps worse on Sunday. The drive to-and-from Sunday morning church services should be fine, but the weather will turn downright volatile and dangerous Sunday afternoon between ~2-10 PM. If possible, stay inside during that time and seek shelter in an interior room or basement if a severe thunderstorm or tornado warning is issued. In terms of severe weather, Sunday has the potential to be the worst day of the year up to this point.

Weird weather… just picked 04” of rain exactly the same amount I got from yesterday’s storm.

[Mount Joy Snowman]

Just got back from a week at Bethany Beach and man it’s nasty out there. At least there looks to be some relief not far off. Sunday sounds like it has some real severe potential. Total rainfall in the gauge for the last week was an even .5”.

Welcome home! I received .79" this week.

Well that's good, because this week, so far, has been pretty lackluster as far as storms go for my backyard.

This weather is absolutely atrocious and anyone who likes it has to be mentally ill or a glass full at all times.
