Amazing. 11:40 pm and my temp is 85 degrees with a heat index of 90!! WOW. Like Arizona but with humidity which is currently 61% instead of 15%. High today here was 96. Highest so far this season was 97.5 a couple days ago.

A little late checking in for posts. BTW I leave this tab opened all year long for convenience. That way I also get audio notifications when new posts are made. It's funny because I was literally on the very eastern edge of that thunderstorm line...by like 2 miles! My lightning detector was going bonkers with strikes (mostly in-cloud/cloud-to-cloud) every second for over an hour. The line stretched from just west of Carlisle westward out to Newburg, then progressed southward into Adams. Interestingly, earlier today a similar line formed in the exact same location and also moved due southward, with me just missing the precip by merely a few miles. What a tease! I did manage 0.09" overnight though and 0.24" yesterday from that almost severe thunderstorm around 3:00pm. Looks like things are calming down now in time for more 90's to come back over the weekend and into next week. It also looks like the ridge begins to break down for a while towards later next week and temps drop back closer to normal for a while just in time to usher in August.

My overnight low was 78.4 degrees. One of the warmest overnight mins I've ever witnessed. @canderson, you are very correct about mins 80 or above being rare. I don't even think it is expected to happen once in a season, so last night was a pretty big deal actually. What a difference today with lower dew points. I dropped to 62 at one point for a bit an hour ago. It's back up to between 64 and 66 now with air temp 95.5. High yesterday was 97.5 late afternoon. Seems likely I'll reach that level again with almost clear skies and full sunshine out there now.

Heat index has been over 100 for the past 3 hours. NWS issued Heat Advisories back around 12:45. Only criticism would be did the models show or not show temp/dew combo creating heat index values over 100? My temp peaked at 96 and has pulled back slightly due to clouds from a tiny shower forming over Blue Mountain at the moment. My heat index peaked at 103 and is back to 101. Feels yucky out there but much better inside where it's 74 right now.

Your statement #1 is correct. Each forecast office must follow the criteria established for their particular forecast region. Their accuracy IS evaluated. While coordination between adjoining offices can be considered depending on the "level of severity", the rules are the rules in most cases. As for what is happening in the LSV right now, it would appear that west of the river our forecast highs are a few degrees lower and are leaving us on the cusp of the advisory. My forecast high for tomorrow is 93. Interestingly, as I write this it's 92 with a heat index of 100. Unless there is a drop in the dew point coming it looks like I'll meet advisory criteria this afternoon.

For those wondering about the dates of the climatological peak for temps in our immediate area I'm referencing local data based on Carlisle from NCDC: The maximum temperature is 87 degrees and is reached on July 9th and then remains 87 degrees through July 20th. So technically tomorrow is the "peak of the peak". As for the minimum temperature, it is 63 degrees and is first reached on July 11th and lasts all the way through August 2nd before slowly beginning its descent. So it's still another 3 weeks until the temp really begins to decline into fall. As for @canderson's comment regarding September the month starts off with a mean of 70 degrees and ends with a mean of 60 degrees. October ends at 49 degrees and November ends at 39 degrees. I usually start getting excited about cooler weather beginning around August 15th because I know it's just around the corner.

I'll comment...lol. Congrats to you for the day. I see a flood warning posted for northeast of you as well. I ended up with 0.42". At least I'm over an inch now for the month. We're going into another dry spell this week, though as temps start out around normal early and go above back into the 90's by week's end.

Same here with 0.34" and more on the way too.

I'm getting appreciable sunshine with lots of blue skies at the moment...lol. 83 degrees with a northeasterly wind 5 to 10 mph. What a sharp cut-off on the western flank. But I guess is has to cut off somewhere. My memory is faded on this but didn't Irene (2011??) take a similar path, grazing the Jersey shore and passing over NYC? I think that was in September though. Very unusual for a due north track up the coast.

Just finished up another great thunderstorm. Torrential rains that looked like it was snowing as the winds blew repeatedly over 30mph. I had at least 4 separate gusts into the 30's with the highest gust at 35mph. It only lasted maybe 15 minutes depositing 0.28" of rainfall. It seems that almost every storm that has managed to hit me in the past month has delivered high wind gusts and torrential rains for a time. Looks like Mechanicsburg getting hit pretty hard right now but it's going to pass maybe just south of MDT.

Another great thunderstorm just concluded. Had no idea anything was coming until the dark clouds started rolling in from the west. Then, kaboom! Torrential rains and the temp plummeted from 82 down to 65 at the end of the event with 0.64" of rainfall. Combine that with the 0.69" that fell late Monday and another 0.03" on Tuesday and I've had 1.36" in the past 3 days. That helps to make up some for what was an incredibly dry June leading into this week. I only had 1.34" for the month as of the 21st, but now am up to 2.70" having doubled the monthly total.

For those who were wondering, the length of daylight on Saturday maxed out at 15 hours 2 minutes 11 seconds. Today, 3 days later we have lost 20 seconds. The first few weeks after the solstices the amount of daily change increases by only 3 to 5 seconds per day. On June 30th our day length will be down to 14:59:00 for only a loss of 3 minutes and 11 seconds...lol. On the winter solstice our shortest day is 9 hours 18 minutes 39 seconds (which actually occurs the day before on 12/20 because winter begins at 5:02am on the 21st and that day is two seconds longer...haha). I have a neat program that gives these times to the second when you input your precise GPS coordinates for Lat/Long. Anyone living along roughly 40'10" north will have these same day lengths. If you live a bit north then you have slightly longer day length on the summer solstice and slightly shorter days on the winter solstice. It's the opposite effect if you live a little south of me. I have a nephew who's an F-35 bomber pilot in the air force. He is literally driving to his new base assignment in Fairbanks, AL this week. I was curious about the sunrise and sunset up there this past weekend. Last Saturday, in Fairbanks, the sun rose at 2:58AM and didn't set until Sunday morning at 12:48AM! Total day length was 21 hours 50 minutes. Fairbanks is less than 200 miles south of the Arctic Circle. He will be deployed there for the next 3 years. I'm hoping to make a trip up there next June to witness near-perpetual daylight.

Totally skipped right over me. Picked up a whopping trace here. All the action was from Blue Mountain on north and from South Mountain on south.

When was the last time you saw a tropical cyclone forecast track like this??? Note...it strengthens (wind-wise) as it reaches Canada Wednesday afternoon!!

I think almost the heart of that cell went close to me. It was some of the most torrential rainfall I've ever seen with visibility maybe 50 yards. Had a peak wind gust to 38mph. Not sure if I had any hail...don't think I saw any. @Anduril are you still at the Staples next to Walmart? If so I'm only about one mile southwest of your store. It was a fast mover as I only picked up 0.27" of rainfall, but that was in about 10 minutes or so.

ALEET! ALEET! It's now official. I have just hit 90.0 degrees for the first time this year. Okay, now can I go back to last Saturday, please?

Can we have this weather for the next 3 months please? Near perfection with high of 70 and lows tonight low to mid 40's. Dew points in the 30's doesn't get much better than this for the soon-to-be start of June!

Wow! Many thanks for posting this info. So I was at least partially right that 2 named systems in May are rare. While I remember the names of the early storms from 2016 and 2012 I wouldn't have remembered them having hit within the past 8 years. My own personal opinion on the January storms is that even though the calendar year was new, it was less than 2 months after the end of the preceding season whereas the current year's season still had over 4 months to go before starting. So the January storms belong in the previous year...imo.

Didn't know about TS Bertha down by coastal SC. I'm sure this isn't a record but when was the last time any of you remember there being 2 named systems BEFORE the official start of the hurricane season on June 1st? When Arthur formed last week I couldn't even remember the last time a named storm came in May. Anyone else have some stats or memories to share?

Yay!!! My wife is so happy because that means the pet salons can open back up in Yellow. At least our dog can get a cut now...lol. On the other hand, I'm sorry for those close to the east shore. No yellow for Dauphin or Lebanon on the 22nd. I know I left out Lancaster. I hope your numbers drop soon!! Meanwhile, in weather news. I just hit 80 degrees here for the first time this year. Dew point of 62 isn't horrible, but after all the cold weather it's going to feel a tad humid. My A/C is on.

Yep! Finally got hit with a decent almost squall-like snow shower. Large flakes this time. Only lasted a few minutes then a few more minutes with finer flakes. Took the temp down from 42 to 38 degrees in less than 5 minutes. I videoed this one for posterity.

Blue Mountain...the downsloping snow eater!!! While the radar looked great and the clouds off to my northwest looked great, I ended up with a whopping 2 minutes of a moderate snow shower. No squall! Nevertheless, snow in the mid afternoon on May 9th as others have already said....unreal. Still looks like a few more chances coming down from the northwest, so we'll see. Sun just popping back out as I write this. Temp dropped to 40.6 with the snow showers. I think MDT will break it's mini-max temp of 48 by the end of the afternoon, from 1947. So coldest May 9th in 73 years here today looking probable.

Oh boy, I can see the snow squall slowly headed towards me. Blue mountain totally gone now which means the snow will be more significant. Radar looks like bullseye hit for me in about 10 minutes. Will send update. Temp 41.9.

Round 2 of flurries just arrived and are flying by horizontally. Temp 41.7.

Happy belated 43rd birthday, then!!! Skies breaking up here now. Glad that I at least got to see the flurries for however short the time was.
