.DISCUSSION...
-- Changed Discussion --KEY MESSAGE 1: Severe thunderstorms with damaging winds and heavy rainfall are possible from mid-day into late evening. Tornadoes also possible. SPC has kept the Enhanced risk of severe weather expectation for all of Central PA today. They have also added a special (conditional intensity group or CIG) hatching to SErn PA (including areas S & E of Harrisburg. The CIG designation means that tornadoes that do develop in that area could be stronger than just EF0/1. A reasonable maximum intensity of EF2-strength tornadoes is possible today - again, mainly in SE PA. Early showers and even a thunderstorm or two will occur near/along a pair of warm fronts moving north and east through the area this morning and early afternoon. The vort max moving into western PA at 07Z is expected to continue to touch off showers this morning. Some lightning is possible, mainly across the S. There should not be a threat for severe weather until at least late this morning after we can get the clouds and showers away and get some heating/pump up the CAPE. The timing of that vort max and the SHRA/TSRA it helps generate look like they will be early enough in the day that ample heating should then occur as the main warm front pushes into the srn counties and across the CWA late this morning and early this afternoon. As the CAPEs climb, and the wind profiles/hodographs become rounded, the risk for deep convection that would also take advantage of the high helicity to produce supercells increases. This convection could start a couple hours earlier than climatologically-favored timing...more like a noon kickoff than early- to mid-aftn. The risk for discrete, spinning cells is highest over the Lower Susq, but is possible anywhere across the CWA with the warm front(s) and varied boundaries from earlier rain and differential heating playing roles to make the near storm llvl/blyr environment favorable. 70F+ dewpoints will arrive in the S with the first warm front, and the LCLs should be low and favorable for tornado development. The Sig Tor Parameter (STP) is highest over the SE, esp in Lancaster Co. Lower (l-m60s) dewpoints hang on across the N for much of the day. The NW will have the next-best chance for severe storms to develop. However, the increasing moisture and moderate-high shear and moderate-high CAPEs will mean we`ll have to watch all of the CWA for storm initiation in early and mid afternoon. These could also be supercells away from the SE - at least early in the event. The wind profile becomes more-aligned/straight hodographs that would be more favorable for storm clusters or a broken line, esp if a pre-frontal trough materializes.

Within the last half hour the thicker smoke showed up here, and you can smell it.

HERE COMES THE SMOKEMassive wildfires erupted in Ontario & northern Minnesota on Monday.NW winds will carry that smoke across the Great Lakes, Northeast, & Mid-Atlantic today & tonight.Reduced visibility & degraded air quality may persist through the end of the week.

The U.S. has approved plans for an experimental satellite carrying a massive mirror, designed to test if “sunlight on demand” is possible by reflecting sunlight onto targeted areas on Earth.The project has drawn sharp criticism from astronomers and environmental scientists.https://www.wgal.com/article/fcc-approves-space-mirror-reflect-orbital/71919795?fbclid=IwY2xjawTC8E9leHRuA2FlbQIxMABicmlkETEyWUk1bkFnTUI4eUI3ZkJPc3J0YwZhcHBfaWQQMjIyMDM5MTc4ODIwMDg5MgABHvIX-pxjYfi4pQg_27rHtfuYb6YHFyPyH5-nyhvboPdnOeVPybIPBTyR54pr_aem_1hzWC-lEWX55Ae_f03FxTA

The latest information has a band of thick smoke moving into our area Wednesday afternoon. If this pans out, I wouldn't be surprised to see Air Quality Alerts issued. People with respiratory problems will want to watch this closely. www.fox56.com/weather

Heat advisories up for Tuesday - not sure why they didn’t automatically extend through Wednesday. .
It's the element of surprise. Just like winter snowstorms you go to bed feeling confident that NWS has an advisory out for 1 to 3 in of snow tomorrow. But you wake up tomorrow morning and it's a winter storm warning for 10 to 14 inches.

Has anyone heard any annual cicadas yet his year ? Last year was a very weak year for them in my area, and this year doesn't seem like it'll fare any better. I thought the rain would help some emerge, but still nothing.
Just heard some today.
