It's a little troubling hearing news about the possible resurgence of the virus in those that have supposedly recovered. We have heard sporadic reports here and there of this possibility but now S Korea has come out with a report of 51 cases of this in the Daegu and surrounding areas. Talking up to a 10% relapse rate. More study will have to be done but I would think governments are rethinking their ideas on how long those infected should be quarantined.

This morning’s short term AFD from MRX: Moving into/through Wednesday, conditions across the TN Valley will improve as the day progresses with the aforementioned low clouds scting out to favor low cu and ample heating amongst sustained sly/swly moisture advection. With that, did keep pops mentionable albeit low during peak heating as iso/sct convection is possible once convective temps are reached (highs in the 70s to low 80s), with low confidence in placement. Meanwhile the synoptic pattern really starts to amplify as a fast moving H5 wave/trough dives out of Canada across the Northern Rockies into the Plains, resulting in surface cyclogenesis across MO/IL. This deepening surface low will propel a fast moving cold front into a very moist/unstable warm sector over the OH Valley late Monday evening with ample convection to accompany. This frontal convection will then race across the Plateau, through the Great Valley, and into the Southern Appalachians around sunrise Thursday. Profiles in the warm sector across East TN are fairly impressive ahead of the convection (despite the timing) with very steep lapse rates amidst deep dry air and unidirectional/strong sheer. As for hazards, nothing is off the table as large hail and damaging winds are certainly the primary threats, but an isolated tornado or two cannot be ruled out as some embedded rotations are likely. Instability does look to wain closer to daybreak as the line of convection moves east, mainly just on diurnal trends, therefore would expect some gradual weakening closer to the NC line. All said, SPC has upgraded areas generally west of I75 to an Enhanced Risk of severe thunderstorms, which is where instability/shear are maximized, while the remainder of the area is essentially favored in the Slight Risk Category. As for timing specifics, the CAMs seem to be in fairly good agreement with only one slower outlier. Typically these fronts outperform as far as speed/timing thus leaned away from the slower outlier thereby favoring a fast fropa between midnight and 5-6AM eastern time.

Lightning detector which I forgot to turn off kept going off so I looked at the extended. Still tracking my last chance of flakes. EPS and GEFS still have a couple hits but think storm track on this not set in stone until after Monday ‘s rain storm.

the thunder woke us up! but the storm blew up just to our southeast.

Just got it up here. Hail, wind, a lot of lightning and rain hardly any thunder. Kind of nice to be woken by it.
-
And all I have here in Hanover is rain, moderate but nothing to speak of, and an occasional clap of thunder. Really no wind to speak of though I might have heard a hail strike or two against the window for about 5 seconds. Boringggg..
-
Kinda looks like the line is intensifying as it approaches DC metro... with maybe a slight bow?
-
Just got woken up by hail, lightning, wind and pouring rain! Did not expect this. What is weird is hardly any thunder.

I'll need a new screen name.
-
New day 2 from SPC was quite meh unfortunately
-
Ah... so the drought didnt follow you on your move lol
-
Pea sized hail and tons of the thunder and lightning. Woke the whole house up..
-
Pretty intense storms. Lightning especially.
-
Booming thunder, frequent lightning and wind gusts above 40 mph with a line of thunderstorms that just moved through here.
-
CMC crusher next week - Today
-
That is one heck of a front coming through. wmpst sorry about your cousin. From what I have been reading there coming up with a break through on how to treat this.
-
Tons of IC lightning with these storms. Pretty much non-stop thunder.
-
Got a good view to the west and can see the "heat lightning" from the storms near Allentown
-
Large enhanced on new day 1.
-
GGEM goes with a massive cyclonic upslope event. -
https://www.spc.noaa.gov/products/md/md0304.html Mesoscale Discussion 0304 NWS Storm Prediction Center Norman OK 1252 AM CDT Wed Apr 08 2020 Areas affected...Portions of southeastern OH...northern WV...southwestern PA...western MD...and far northern VA Concerning...Severe Thunderstorm Watch 85... Valid 080552Z - 080715Z The severe weather threat for Severe Thunderstorm Watch 85 continues. SUMMARY...A line of strong to severe storms capable of producing mainly damaging winds will continue east-southeastward. Downstream watch issuance is possible. DISCUSSION...Storms have grown upscale across parts of southeastern OH into western PA, with mainly severe/damaging winds being reported, including a gust to 75 mph at the Pittsburgh International Airport. The airmass downstream of this ongoing convection is not particularly unstable given cooler low-level temperatures and less low-level moisture. With MUCAPE generally 500-1000 J/kg, storms may have a tendency to become slightly elevated with time, particularly with eastward extent. Still, given the well-organized nature of the line and strong outbound velocities noted on KPBZ radar, there appears to be a continued strong to damaging wind threat that may extend to the south/southeast of ongoing Severe Thunderstorm Watch 85. Accordingly, another watch may be needed across parts of southwestern PA into western MD and the eastern WV Panhandle. ..Gleason/Thompson.. 04/08/2020 ...Please see www.spc.noaa.gov for graphic product...

Pittsburgh PA Spring and Summer 2020 Thread
jwilson replied to meatwad's topic in Upstate New York/Pennsylvania
Well that was an intense line, definitely one of the most dynamic cells I've witnessed since living here. Tornado warning popped on the TV, but it wasn't really for us. Hope you're all good up in New Kensington. Twitter report said there was a tornado near Markle. I was watching power flashes in the distance from my viewpoint. Actually a lot of other strange lighting colors during the storm, as well.
