Mt Holly confirmed a couple of hours ago that a tornado did touch down in east Allentown near the same area 15 years ago yesterday - Dieruff High school area. Magnitude/track is not yet known. I expect after seeing the damage myself that it was an F0 or F1 at the most. IMHO, twisted trees with snapped off branches near the top of the tree canopies was one of the confirming issues along with siding being peeled away from the sides of several structures and pvc panels from solid 8 ft high stockade panels scattered amongst the debris field. Lower Macungie Township township building near my house , trees across the powerlines which brought down tons of wires closing Brookside Rd most of the day- power out at the township building and they had to operate on the generators most of the day.

yep, straight line wind damage was the only threat. Dime to quarter size hail reported in our area too. Had branches down around my house- nothing too big. 50-60 mph winds for sure. 1.15 in the rain bucket- happy about that. Simple squall line no real training. Another t-storm line out west of Harrisburg- wondering if will make it here before 3 am?

Hit the nail on the head with this statement. 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.

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.

not frustrated that the drought is somewhat diminished which is good however, I am very frustrated that this Canadian HP dominated weather pattern has been so unpredictable in our forecasting. When you call for severe weather and 60% and nothing happens at all, its like getting virga for a winter storm warning. Many people count on their daily activities for a somewhat accurate prediction. I hate to spend money watering or washing cars and put off those activities until needed. If a 60% chance of rain is called, you can bet I will not be washing the car for example. Hit and miss diurnal t -showers should never be classified as a 60% chance in any forecast. The MCS and squall lines storms are constantly forming over western PA only to diminish in their intensity by dusk before they hit eastern PA. I think only one or two times this entire summer season have I experienced a t storm after sunset. Thats is rare and I am really surprised we are not talking about this type of event more often. When is the last time we had training t-storms with constant lightning at midnight? Take a look at the midwest on the radar every evening in the past week or so. The ring of fire t- storms have been firing up along a line from Iowa and Illinois down to Alabama and the freaking storms stay together all night long. I would love to see that here just a few times during the summer. Enough ranting. Monday forecast, I will believe it when I see it. It is not cast in stone thats for sure for 1-2 in of rain even the PWATS say 2.5 in. I do agree its the best chance of seing a significant rain in awhile. It will be a million dollar rain for corn and soybeans for sure.

those freaking t- storms in central PA are hitting a brick wall on the west side of the Blue Mts. I have not had a good rain in almost three weeks now. The severe t- storm watch should be dropped and chances of rain reduced to 30% for tonight as the squall line appears tobe in a disarray. Right now anyone SE of Hazelton is getting nothing tonight if these storms keep fizzling out

My first call -- lots of southern sliders as the PV has to lock in early over the upper midwest in late November for us to see some "Big Daddy's" Lots of rain to sleet to snow storms and us being on the cusp on every storm event for precip types until early January. If one cold PV system locks up in mid December- game on. Actually the major game changer for this winter is a tropical system in late October for our area which can quickly rearrange the flow of frontal systems and change our weather pattern. I have seen it a bunch of times. The key will be how strong the tropical system will be and how it will help pull down colder air when it departs. Then the new pattern sets up for the next 30-60 days. The deeper the tropical system, more colder air dumps in behind the system.

omg Wake up Wednesday morning and you can almost see your breath at near 50 degrees. Cannot wait. The grass will love it as soil temps drop a few degrees too.

https://www.foxweather.com/weather-news/pjm-interconnection-heat-alerts-us-power Basically it is a warning to the generators(suppliers) in the PJM electrical system to be online as demand will peak by Saturday evening. They maybe fined if they are not online. Key- everyone needs to reduce their energy needs. Weekend should help as many people will be involved in outdoor activities. Media blowing it oout of proportion. I worked with PJM in Lower Providence and Milford Township facilities. Their grid system is unbelievable and they are located in concrete harden bunkers literally 50- 100 ft underground with giant computer screens controlling every power switching station . They are the guys that saved PA from the 20013 NE blackout from hitting our area. https://www.foxweather.com/weather-news/pjm-interconnection-heat-alerts-us-power https://insidelines.pjm.com/fifteen-years-since-northeast-blackout-reliability-remains-top-pjm-priority/

add that to your 13 inches of rain for the month. Zilco here and parts of my area are still in a PADEP drought watch as the media reported.

no t-showers on the radar within 200 miles of here. Please someone tell me how a 50% chance of t storms with a potential of severe suddenly pops up in the next few hours. C'mon man.

well the drought guy has not had much rain in the past week. Less than .50 in. Everything blooming is to the southeast or northeast of western Lehigh county. Did see some t showers at noon but it was too early in the day for any significant rain. These storms appear to grow in the western burbs of Philly and go full board by the time they hit eastern NJ. Its been that way for weeks on end. Last night by the time the t- storms hit the Blue Mts from Harrisburg, they were just light showers when they hit my area.

.45 in with afternoon thunderstorm- typical afternoon garden variety but no hail or wind gusts over 20 mph. Already going NE into Allentown and Bethlehem. Sun coming out

I sure would like to know who is calling 60% chances of rain at Mt Holly? 20% would much more accurate. No more than 20% of the FWA have precip any any given time lately. When the public sees 60%, they start canceling outdoor events. Hitting 90 degrees for three days in a row is not being accurate as well. These short range models in this current pattern absolutely suck. Shortwaves also do not mean uniform precip coverage.

well, here it comes- first closing because of high Bacterial counts in our area from the first flush of these intense downpours like I said a few days ago. More will be coming: https://www.lehighvalleylive.com/news/2023/07/beltzville-lake-closes-to-swimming-following-high-bacterial-counts.html By the way, another major sinkhole a mile from my house https://www.wfmz.com/news/area/lehighvalley/sinkhole-opens-behind-home-in-macungie/article_820c630c-1ff2-11ee-9973-47ea2197cdce.html#tncms-source=More-from-newsroom-(right-column)

by the way, I received 2.85 in of rain for todays event. Very productive

Yes they are up but they will come down quickly. I would like to see lighter thundershowers over several days in the course of the next week. These drenching downpours will help the corn and and soybeans and green up yards but we need long duration rainfalls to get the rain into the ground. A few 90 degree days this week will make this storm a distant memory. This storm was a million dollar rain for farmers. If we have several 90 degree days, the corn will be head high by next week. This storm event also really helped the trout population environment as thermal pollution was nonexistent today with the cooler water runoff temps. The downside is that in the waters such as Lake Ontalunee and Blue Marsh Lake in Berks County, I am betting huge algae blooms and high bacteria counts in the upcoming days which may curtail water recreational activity over the next five days or so as this warmer warmers just received a huge flush of runoff and bacteria followed by much warmer temps. watch the media

basically just enough to get the street wet. Cooled down but made it more muggy here in Macungie. Was at 93 down to 81 now. The debris clouds from these pop up showers make things worse and stifle redevelopment of t- storms for the rest of the afternoon. Can never get a full fledged heavy rain event unless the storm dies out right over you as fast as it forms. God, I miss training t- storms. Have not seen a good training t- storm in years

let me know the results please. Thanks
