Same here. We have elevation though.

The forum heat source!

Check out the prevailing temps in and near the highlighted areas and then look at them outside those areas....even due south into MD. It's still in the 70's in Eden Twp Lanco.

Lots of places on that blob I drew are more rural BUT are south of Harrisburg in some manner. Almost like the typical prevailing winds carry it in a semi circle out from the city for a bit until the effect is lost. Just a thought but its been fairly consistent this summer. Last summer you and I were fairly close on temps but not at all this summer (most days). I only hit 90 one day during the August hot stretch.

Just having been in Palmyra last week I would definitely not consider you part of the 'Burg Metro Hot Zone. Slow goings in town.

Its peculiar and the thing that bothers me is that no model is representing it in any way. The modeled temps all match up well with what is being shown in Franklin, Adams, Central and Southern York, Central and Southern Lancaster, etc....headed for a high today of 83-85. It truly does seem like the people, concrete, and traffic are artificially raising Temps around and slightly to the South of Harrisburg. Its only 81 at my parents house in Valley Green right now. Outside the Harrisburg Metro hot zone apparently.

Might have to consider designating the Low Lands of the LSV area their own microclimate as I saw the comments about mid 80's to 90 today and just came back in from a 78 degree walk out to get the mail. Checked Wunderground and that same area all summer is getting hotter than areas to their North, South, East and West. 78-82 at all reporting stations on the Mason Dixon right now.

That is scary. Enough to unweather nut someone and stop wishing for extremes.

At MDT the high temp that month was 42 and you can assume off the summaries that all precip that fell, 1.09" worth, was snow. 11.2" total. 13 days the temp fell below 10 at MDT. Cannot imagine what the real temps were for the out of city folks.

A -8 January. Ouch. That is cold.

Not likely but my interpretation of the last few GFS runs was a a -4 to -6 departure going into the last 7-10 days.

Highs in the 60's for several days would put MDT into the mid negatives even with night time lows not being so low. That would be 10-15 departures for highs. There are 3 on the 6Z GFS for MDT but there were a few more on the 18Z last night.

MLCape is high enough, per AFDs, that there is going to be action this afternoon. If it gets in a line like the Meso's suggest we all should see some or maybe just a few unlucky skip overs.

@Blizzard of 93, the 3K Nam suggests I would get to mow again next weekend.

The GFS is close to be more hot than we want though. So it appears its going to be a close call. GFS would suggest we make a run for -8 Sept Departure.

Little tint of red at the bottom. Red Sky at morning, sailors take warning.

Great pic. Like something you would see on the cover of a book (a book about big rigs in this case by the sky itself).

58 this AM. SPC upped/expended the risk for today. So did the NWS Zones which now say 1-2" of rain for some in the LSV (tonight). 5% tornado is also back to MDT now.

18Z GFS... from 6Z Fri the 17th until 18Z Mon the 20th, the temp at MDT stays between 60 and 65 the entire time.

My continued dissection of summer appears to have inadvertently lead you to the wrong thread. Apologies. Lol

It's just an opinion but lines up with the same theory of our world rushing the good seasons like putting out Christmas stuff in Sept and Oct.

Looks like someone "talked" WPC into issuing a FFW for Eastern PA. Throw the science out the window. It's gut feeling time. Just like on these boards, peoples true thoughts come out in seemingly agnostic postings. The AFD writing Met for Phl thinks tomorrow is a big risk day while CTP's met is reaching for the sun screen and thinking its a nothing burger. SPC/WPC continue to place MRGL outlooks for Excessive Rain and SVR over the eastern 1/3 to 1/2 of the CWA for Wed afternoon and evening, INVOF a nearly north-south lee trough. Marginally stronger llvl winds and vorticity will occur across our mid and upper Susq Mainstem counties where the close proximity of the aforementioned warm front will create a very low prob of a few transient supercells and perhaps an isolated, weak tornado (indicated by PCs inclusion of the 2% risk area over CTP`s eastern zones in their Dye outlook). Heavy rainfall risk is highest well east of my CWA, and WPC was talked into a Day 2 SLGT risk over far eastern PA for Wednesday afternoon/eve.

If you look back at the first Winter 20/21 and Fall 20 thread you will see they both started using the dates Met's use. So I still contend that this is a primarily cold driven board which is fine using Met dates for fall and winter but uses Astro dates for Spring and Summer as sort of a "well if I have to, I have to" way of trying to hang on to Winter and Spring longer.

SPC maps for tomorrow
