Pittsburgh/Western PA WINTER ‘25/‘26

[Gordo74]

Well don’t I look the fool for making fun of the ides of March storm and now I’ve been without power since 6pm with no ETA.

[Ecanem]

Hey all.  With all the crazy weather I’m sure like you guys.  I’m always the ‘weather guy‘.  So I decided to create a mini hyper local weather app.  
 

This combines: 

1. my house tempest weather direct feed 

2. hrrr data from gribstream

3. Google pollen api  

4. nexrad level 2

5. open meteo aqi and pmi 

6. Rainviewer (regional rain and satellite) 

7. NOAA spc meso 

8. GOES-East from Iowa state  

 

https://scarlett-weather.delightfulplant-db525447.eastus2.azurecontainerapps.io

this is super beta and was a fun project with Claude code but I thought you guys would like it.   I’ll probably put it on a domain sometime soon. It was really meant for my neighbors but would love weather geek feedback.

Very cool! What did it pick up as far as max winds?

Yesterday it topped at 50mph before the power clipped out and the feed dropped.   May have been a higher gust.  It’s in a relatively good spot but still can be blocked from NW gusts. 

[Burghblizz]

0Z NAM with a mini-Namming, showing 6”+ with the frontal passage of the big Midwest storm Monday afternoon. As you would expect, that backed off a little this morning

Will still be interesting to see if that’s just a little white rain, or if there can be a period of accumulating snow. 

[TheClimateChanger]

Up to 66F at PIT. If we can hit 70F, that would be the fifth 70+ day of the year already, which would match 2025, 2000, 1946 & 1876 for most on record. Little bit of weather trivia there.

[Ecanem]

68.7 on my tempest right now 

[Rd9108]

Looks like we might get a repeat of what the east coast dealt with last week with their frontal snow. I think it was mostly in the 2-3 range.

[colonel717]

Hrrr like Beaver Co thru Cranberry 

[colonel717]

[ChalkHillSnowNut]

Im done with snow but if I can get 3-5” on the grass when it’s cold I’ll take it-it can be gone Wednesday 

[PghPirates27]

 

High end would be wild....

NAM had this look a couple days ago, and now has it back. Would have to thread the needle with timing. I’m on a work trip, so book it! :-)

[TheClimateChanger]

Well defined cold front just entering into Pennsylvania.

[Rd9108]

Nws mentioned up to 1.5 inches per hour rates. Shaping up to a be surprise event

I'm not expecting much accumulation, but I won't be mad if I see some moderate to heavy snow briefly. NWS did mention amounts increased again with 12z, it should help it will be late evening so sun angle won't be a huge impact, it will just need to overcome the warmer ground.

[colonel717]

Heavy snow here now. Laying on mulch and roofs so far

   Mesoscale Discussion 0280
   NWS Storm Prediction Center Norman OK
   0513 PM CDT Mon Mar 16 2026

   Areas affected...West Virginia into far eastern Ohio and western
   Pennsylvania

   Concerning...Heavy snow 

   Valid 162213Z - 170215Z

   SUMMARY...A swath of moderate to heavy snow will spread
   north/northeast in the coming hours. Snowfall rates may locally
   increase to 1-2 inches per hour.

   DISCUSSION...Recent regional radar mosaics depict transient bands of
   moderate to heavy snowfall within a broader precipitation shield
   across the central Appalachians/upper OH River Valley. Surface
   observations under the heavier bands have been reporting periods of
   visibility reductions down to 1/4 mile. A broad swath of moderate
   snowfall will be maintained through the evening as ascent within the
   left-exit region of a 120 knot 500 mb jet continues to shift
   northeast. Increasing 850-700 mb frontogenesis will continue to
   overspread the upper OH Valley and provide more focused mesoscale
   ascent favorable for focused snow banding and periods of heavy
   snowfall rates. Although the strongest lift will likely be focused
   within the 850-700 mb layer, ascent through 500 mb will include a
   roughly 100 mb-deep dendritic growth zone. This will also help
   maintain moderate to heavy snowfall rates as surface temperatures
   fall below freezing within the post-frontal air mass. Based on
   latest guidance, snowfall rates over 1 inch/hour appear likely and
   may periodically be as high as 2 inches/hour across portions of PA
   and within the higher terrain of the Appalachians later this
   evening.

They've finally pulled the trigger on a WWA. A little surprised it wasn't issued sooner, given the robust anafrontal precipitation shield.

2" on the deck railing here in Hopewell already. 

[Rd9108]

Funny how it doesnt take long before the pavement and roads cave. It was just like 80 a week ago.

[RitualOfTheTrout]

Ripping heavies here! Wind is gusting too! Pavement and sidewalks caved.

It helps it was overcast all day, but also rates and late evening can overcome warm ground.
