Central PA Winter 2024/2025


Recommended Posts

Rain, possibly mixed with sleet or snow after 1am for me per CTP. I'm sure the roads will be just wet with that, plus PennDot salt. 

I was hoping for a delayed start tomorrow, but it appears to be just a shitty weather long day for me. 

Wish the snow would have hung on until daybreak.

31/26ºF here with the precip on the doorstep. It’ll be interesting to see if this overachieves in the snow department here today. Models have been progging the column temps to fall a couple degrees below freezing at 925 and 850 upon precip onset. I’m thinking there will be a period of snow for a bigger portion of the LSV than what is being broadcast for advisories. Whether that escalates into an actual advisory event in Harrisburg/York/Lancaster is debatable but it’s certainly possible. I’ve liked the HRRR’s more frozen vs rain (colder column after onset and during first part of the event) over the 3k NAM’s more widespread freezing/mixed precip during its wintry precip portion of the event. We’ll see how that goes today. 

I think primary freezing rain threat resides in the Laurel Ridges, however I will say given how cold it has been that rain and marginal temps at or a degree or two above freezing may freeze up some surfaces like non-paved driveways and other untreated cold surfaces. It was 12ºF for a low here Saturday morning and was down as far as 21ºF last night before clouds moved in a brought temps up overnight. Ground is frozen solid.

31/23 here.  Nothing yet despite solid radar snow echoes.  Wet bulb is 28 degrees, so once the precip gets going good, the potential to drop to 29 is here.  After the pressure hovered around 30.70" all morning it has now started a steady descent and is down to 30.63".  In the climate section of last night's CTP disco they mentioned some historical pressure readings from MDT.  Yesterday's max reading at MDT got up to 30.97", which was 0.02" of tying the monthly December record of 30.99" which was set back on December 25th, 1949.  The all-time highest pressure recorded at MDT still stands at 31.09"   I'd like to find out when was the last time MDT reached 30.90" or higher.  I think it's been many years.

As of 1:15pm precip has finally started.  It's a mixture of snow and sleet, but light intensity.  Temp holding at 31.5 degrees with a dew point of 24 degrees.  Wet bulb has risen one degree to 29 degrees.  I'd say evaporational cooling potential is now up to 30 degrees.

current weather observation from middletown claims snow they are only talking about radar imo nothing is going on not a flake yet. they have been doing this for 5 years at least no longer confirm it with eyes but if it says rain or snow on radar the current conditions says this. I guess they dont want to pay those who use to go out to confirm the current weather any more? with that said was under returns showing snow for 2-3 hours still nothing. current temp is 31 dewpoint 23 its going to be a while before we see anything with it that low.

Getting it going nicely here moderate snow and things getting coated, radar looks good for the next little bit. Let’s see what happens in the heavy returns moving in

These heavier returns overcame the shallow warm layer.  Some big ones falling.  Getting roof coverage.
