Some models are extremely bullish on a tornado threat. I will be out chasing if some good supercells get going. the straight line wind damage is a real big threat more than tornadoes. Would not be surprised that many tornado warnings could be simply issued for rotation on radar echos when in realty they are simple straight line wind damage paths. Yesterday in Tn , reversing gust fronts happened. Talk about rare for straight line wind damage paths. Hail damage maybe a concern as updrafts become very severe too.

ChescoWx Posted August 6, 2023 Share Posted August 6, 2023 A seasonably warm day on tap today to close out the weekend before wet weather moves in tonight through much of Tuesday. Some spots could see up to an inch or 2 of rain. Wednesday looks like the best day of the week before more unsettled weather arrives toward the end of the upcoming work week. Records for today: High 104 (1918) / Low 46 (1957) /Rain 2.17" (1938) 1 Link to comment Share on other sites More sharing options...
LVblizzard Posted August 6, 2023 Share Posted August 6, 2023 12z NAM has a PDS Tornado sounding for northern Lehigh County tomorrow. If a storm can tap into this… 1 Link to comment Share on other sites More sharing options...
ChescoWx Posted August 6, 2023 Share Posted August 6, 2023 So how cool has the summer months of June and July been across Chester County PA? At East Nantmeal this is the 16th chilliest summer so far out of 130 years of data. At Glenmoore it is the 33rd coolest summer to date with 67 years of records and finally at KMQS Coatesville Airport it is the 3rd chilliest to date with only 16 years of records back to 2008. As you can see in the graph below the average temperature trend is clearly for cooler summers than in our past here in Chester County. Link to comment Share on other sites More sharing options...
RedSky Posted August 6, 2023 Share Posted August 6, 2023 Problem with tomorrow's severe potential is it projects as two rounds, one will be early in the morning and the second is after sunset. 1 Link to comment Share on other sites More sharing options...

Also, almost always the first round always robs energy from the second round it has happened this year a few times already. I would expect the energy robbing will be problematic also cloud debris could be another issue. 2 Link to comment Share on other sites More sharing options...
LVblizzard Posted August 6, 2023 Share Posted August 6, 2023 Tomorrow could go moderate towards the York-DC corridor. Would be the first moderate risk in PA in over 5 years (5/15/18). Link to comment Share on other sites More sharing options...
Hurricane Agnes Posted August 6, 2023 Share Posted August 6, 2023 SWDY2 got a bit of my attention. Ended up hitting 85 yesterday after a low of 68, and have so far had a high of 88 today after a low of 66. Had hoped the dps would be a bit lower but they only got down to around the mid-60s before creeping back up again. Currently changeable skies and 88 with dp 69.

KamuSnow Posted August 7, 2023 Share Posted August 7, 2023 Started raining here about an hour ago, got about 0.08" so far. With the better returns getting closer, the breeze is picking up nicely. Feels nice and active out, lol. 72F here at the moment. Link to comment Share on other sites More sharing options...

We've got .17" in the bucket thus far tonight. Though it seems the recent "maintenance" on WU has broken some things: This really pisses me off. I really need to come up with an offline solution for data-logging. 1 Link to comment Share on other sites More sharing options...

Hurricane Agnes Posted August 7, 2023 Share Posted August 7, 2023 Got a good soaking overnight with round 1 starting after midnight and still going lightly at post time, although that appears to be leftovers.

Kevin Reilly Posted August 7, 2023 Share Posted August 7, 2023 Currently low clouds racing through 69 right now dewpoint 66. Picked up 1.05" last night first round came through at 11 PM finished up by 1 am a break then got more 2 AM to 4 AM. Round one had some good winds with it 25-35 mph out of the SW no lightning at all with any of that last night. Link to comment Share on other sites More sharing options...

The 2-3 inches of rain called for on Monday from yesterday morning has quickly dwindled to less than one inch. I am so tired of this crap. Stratified debris cloud cover again this morning with less than .25 of rain last night. The street is already dry. If the sun comes out this afternoon, we will get a solid line of severe t- storms but no where near 2-3 in of training t storms precip. Again and even MT Holly brought it up in this mornings discussion, the convective nature from last nights showers were negligent. It seems that lighting does NOT want to happen during the night in our forecast area this year. Link to comment Share on other sites More sharing options...
LVblizzard Posted August 7, 2023 Share Posted August 7, 2023 Upgrade to moderate risk (45% hatched wind!!!) southwest of Lancaster. Enhanced covers the whole area besides for the shore. I’m thinking the best storms stay south of the turnpike. 1 Link to comment Share on other sites More sharing options...

ChescoWx Posted August 7, 2023 Share Posted August 7, 2023 It looks like more showers and t-storms will be around after 5pm this evening - some of the storms could be severe. The weather turns nicer for midweek before we see shower chances return for both Thursday and Friday.

A few severe storms capable of producing tornadoes could sneak into southern and southwestern Delaware County into points south and west. 1 Link to comment Share on other sites More sharing options...

It's still overcast and in the 70s (at least where I am in NW Philly). I finished up with 0.67" from that overnight/early morning round and it's currently a steamy 74 with dp 72.

The Iceman Posted August 7, 2023 Share Posted August 7, 2023 MT holly mentioned that there's concern that the stronger convection to the south of us robs potential convection to the north and I agree with that thinking. Guidance is currently split on whether intense convection makes it into the region later on. I think the bust potential is unusually high today. 2 Link to comment Share on other sites More sharing options...

I really think the main threat is perhaps SW Delaware County Points south. We already have a stabilizing feature here now with these clouds from about Central Delaware County points east and northeast with all the cloud cover. These low clouds were showing signs of burning off at 7 am but there are firmly entrenched for now. Link to comment Share on other sites More sharing options...
Phillycane Posted August 7, 2023 Share Posted August 7, 2023 I'm down in OCNJ currently and after the rain ended about an hour ago the sun is out but not sure for how long. **Edit: And now the clouds are back. ** Link to comment Share on other sites More sharing options...
