LVwxHistorian Posted December 31, 2021 Share Posted December 31, 2021 So the lowest high temp. at LVIA this month was 36 on 2 days which is only surpassed in the warmest DEC ever, 2015, when the lowest high was 39, though 2015 was MUCH warmer overall with +13 degree departure (current month about +4). DEC 1923 also had 36 as its lowest max., but that's with 3 days of missing data and having been taken in downtown Allentown instead of at the cooler airport. 1 Link to comment Share on other sites More sharing options...
Albedoman Posted December 31, 2021 Share Posted December 31, 2021 whats the latest day for measurable snow in allentown? It maybe in jeopardy? 1 Link to comment Share on other sites More sharing options...

What combined sources do you use for your data?? Link to comment Share on other sites More sharing options...

Elevation is 254' vs 390' and distance about 6 miles, and in the 1920s and 30s there wasn't too much urban heat yet so .... What you should really be worried about are Gordon's messed up snow figures, lol! 1 1 Link to comment Share on other sites More sharing options...
Albedoman Posted January 3, 2022 Share Posted January 3, 2022 Goody goody, breaking the latest no measurable snowfall record is still in play. The 12Z model runs are insisting on breaking this record too as they too are already pushing the next storm out to sea. The east central snow hole lives on Hurray. 1 Link to comment Share on other sites More sharing options...

Albedoman Posted January 3, 2022 Share Posted January 3, 2022 No way 12 to 18". The models cannot even agree on one inch right now outside of 24-36 hours . What are you smoking? I want some of that. I would love to see that amount but it is not in the cards right now I agree there is a 50/50 chance of a measurable snow right now for the LV and that is all I can agree on with this chaotic LR model runs and the extremely progressive jet stream over the US. One run shows 12-18 in, the next makes the storm disappear all together. The model runs both short and long range are pretty bad right now as the buoy data in the Pacific cannot be ingested quick enough into the models because of fast jet stream to make them more reliable. I keep saying we need to send drones over the PA ocean and SW desert areas to supplement the atmospheric wind/temp data gathering over vast open areas and to perhaps help launch more weather balloons . I am surprised nobody at NOAA has thought of that 1 Link to comment Share on other sites More sharing options...

That's a good idea about drones -- I guess it's because they're still an emerging technology, especially as far as data collection goes 1 Link to comment Share on other sites More sharing options...
LVwxHistorian Posted January 4, 2022 Author Share Posted January 4, 2022 How about latest day with at least an 1" -- Feb 9, 2017!! 1 Link to comment Share on other sites More sharing options...
Albedoman Posted January 4, 2022 Share Posted January 4, 2022 lets go for it. We got nothing to lose right now. 1 Link to comment Share on other sites More sharing options...
