At 11:30 my temp has gone absolutely nowhere since 7pm. It's 32.0 degrees. Has gone back and forth between 31.8 and 32.2, but mostly 32.0. My dewpoint is 19.6 degrees with a relative humidity of 60%. My wet bulb reading is currently 27.7 degrees which also has not changed either. With these temps it will be easy to drop quickly to 30 degrees and then likely 29 degrees when the heavy precip comes in. The anticipation continues...

High today 35.6. Temp has dropped back to 34.3 with a dew point of 17.8. Overcast has varied with a bit of sun getting through, but generally no sun for most of today. I think the key to how far temps can drop after the precip gets going is the wet bulb. Mine is currently 28.6. That gives wiggle room to get below freezing by the time precip begins. My PNC from NWS this morning had for the overnight..."sleet, possibly heavy at times...". That's something you don't see often.

12k gives me almost 4" while 3k gives about 2". I'll split the difference and go with 3", followed by a heavy sleet storm that maybe ends as a little freezing rain. I don't think I've ever seen intense purple over me on Pivotal before. The GFS from 12z this morning also had heavy sleet around 4am Thu. Oh how the anticipation is building...lol.

The forecast high for me earlier today was becoming sunny with a high of 53. Instead, the overcast held on until after 2pm. That limited sunshine was only able to push temps up to my high of 44 degrees. The projected low temp for me tonight is 40 degrees. My current temperature is 30.6 degrees. Looks like CTP needs revisions.

Ice Storm Watch??? Breaks in OVC with blue patches beginning to appear. Sun not out quite yet but soon. Temp has crawled above freezing to 33.1 after a low overnight of 22.6 F. There must have been a period of cleared skies to allow that cold of a low with a few hours of radiation. Already a tiny bit of crazy. Also, I have determined that the majority of my precip last night was not freezing rain, but rather sleet. There had to be some freezing rain because the sleet is stuck together. I think I'm going to record 0.2" of sleet/snow for yesterday. I'll have the melt down shortly.

I've only within the past 15 minutes caught up reading all of this afternoon's post. I had no idea people were getting snow/sleet. I never saw anything falling through sunset. I guess it must have started right after that. Actually, right here I have a solid coating of ice all over my car, and it's lumpy ice. That implies that sleet was falling with the freezing rain. Upon further inspection I can see the coating all over my driveway. There might have been a small bit of snow but it really had to be primarily freezing rain mixed with sleet. Temperature a few hours ago was in the upper 20's, and has risen to the high of the day at 31.3, but now has dropped back slightly to 30.9. I can certainly understand all the accidents. Temps were in the mid teens this morning throughout the region. I don't think there was freezing rain potential mentioned in this morning's forecast, was there? Instant black ice with virtually no warning. As bad as running head on into a snow squall.

Wow...what a change from DT's 2nd half of winter video from 1/30. Although, he did imply that beginning around Feb 20th and until around March 20th there was a good chance that winter would return in force. So, it's just sped up 7-10 days sooner.

After a low of 16.3 degrees the temperature has very slowly recovered to 24.6. Dew point has been hanging out around 10 degrees all day yesterday through the present. My earlier filtered sunshine has progressed to a solid overcast. Looks like exciting times are on their way back during the entire month. I don't think MAG was talking about a snow to freezing rain scenario for the upcoming Wed/Thu system. As depicted, 2-3" of snow followed by a light coating of ice is another great way to retain the pack.

Here in Carlisle, I had 0.27" of rainfall yesterday, plus a straggler 0.01" overnight. For the month of January I recorded a liquid total of 0.80", probably the driest January in many years...possibly ever (for me). January of 1977 is the only other exceptionally dry month I can remember. The only rainfall for the entire month occurred on the first, and then the 31st. All other precip was snow. Except for shovel patches here and there all other snowfall has melted and is gone I recorded approximately 10 consecutive days with solid snow cover, with a few additional days with partial cover.

Here in Carlisle, approaching 12 noon, my temperature is creeping up oh so slowly to 37.4 The high for the day occurred after midnight at 39.9 while my low before dawn had dropped to 33.4. I've had a whopping 0.03" of rainfall so far bringing my monthly total up to 0.61". I agree with everyone else regarding the consistent reductions in storm totals for rain events. 24 hours ago my p-n-c added up to between 0.75" and 1.00" by late tonight. Last night it had dropped to 0.50" total, and right now it's calling for a tenth to a quarter this afternoon followed by less than a tenth tonight. The new total range is now between 0.15" and 0.30". Oh well, I'm waiting for the rain to wash away the salt in my driveway. I can't remember seeing this much salt before (at least the last 5 winter seasons).

I would like to thank @Itstrainingtimefor his earlier post(s) about starting a banter thread. I'm also surprised that you remembered that it was I who first made that suggestion either sometime last year or the year before. I have held my peace this season because I know that my active participation is not year round. Thus, I know that there would be a least a few who feel that I don't really have a right to make that kind of suggestion. My angst over the past 6-8 weeks or so has not been about political posts, which at most have contributed to maybe a few percent of all posts. Clearly, the problem was, and continues to be, with the 95%+ posts that were sports-related. I'm not exaggerating when I say that literally there have been hundreds of posts. I mean, a few weeks ago there were over 40 posts in a row that were sports talk. Well, for one thing not everyone in this subforum is into sports. But, it's not even about that. It's the point that this is a weather-based forum, and we are a weather-based subforum. There are more than enough sports forums out there on the interwebs online to keep you satisfied until the cows come home. What is so horrible about having a second thread for talking about anything else? If you don't want it cluttered with topics that are not sports, then make it a sports-only banter thread. Finally, I believe I have the most incredible, simple solution to this ongoing problem. It's called a second browser tab. All you have to do is open that tab and then point it at the sports/banter thread. You can place the two tabs right next to each other. And, best of all, it would only take a few milliseconds to switch between our weather-only thread and the sports thread. Why is it so important to include posts that are off-topic? I hope that some of you realize that I'm being just a tad facetious here. I'm sorry for being long-winded. Most of you know that many of my posts (this one included) are typically more than a sentence or two. I'm a detailed-oriented individual who has a difficult time speaking without details. So, that's it from me regarding this whole ongoing controversy. @Bubbler86, you made a comment about having others put you on ignore in order to keep off-topic posts from you being visible. If I did that I would lose all of your weather posts, which are many, and that I look forward to reading each day. I hope that everyone here will heed @Itstrainingtime's advice and start posting non weather-related topics primarily outside of our collective, beloved, weather community.

My low here this morning was 11.8 and my low yesterday morning was 12.7. I still have about 3" solid snowcover in my north-facing backyard. In my south-facing frontyard patches of bare spots have started to appear, especially after yesterday's balmy high of 44.2. I would estimate that 85-90% of the front yard still has at least one inch of cover. Concerning the earlier post from @Itstrainingtime, regarding the use of the word "breezy" in the nws forecasts, while I don't know the precise value, it is the sustained wind, not the wind gusts that determines the use of "breezy". I believe the threshold is sustained speeds of 20-25 mph. When the sustained wind is forecast to exceed 30 mph the adjective changes to "windy". The gust speeds and the frequencies of reaching these values are what is used to determine wind advisories and high wind warnings. I think that frequent gusts over 40mph qualify for a wind advisory while frequent gusts over 50mph+ qualify for a high wind warning. Please don't hold me to precise values for any of the wind speeds. I'm pretty sure the values I mentioned are at least "close" to the correct figures.

I wonder if it will be the coldest January since 1994? or perhaps 2015? I haven't looked at the current data, so I'm guessing MDT will come in 3.5 - 4.0 degrees BN. If I don't record any more precipitation the rest of this month, it will almost certainly be the driest January I've ever personally recorded. I've only had 0.58" of liquid for the month. It's only been 3 months since the driest October and for any month I've had with just 0.43". I'll have to see if that was all melted snow or if it rained at all near the beginning of the month. It's been so long I can't remember!

These "sudden" colder temperatures at MDT are remarkable. I'm used to them almost always being warmer than me. Well my high today was 32.2 and my low was 7.0, making MDT 2 degrees colder in both high and low temps. The frozen river really must be having an effect on their temps as others have postulated.

Just before 1:00am I am 5 degrees below my forecast low of 13 at 8.1 F. I'm not expecting zero or even below for a 4th consecutive night. My dewpoint is currently +4 F so I'll pick +4 to +5 for my overnight low. My high earlier today (yesterday) was 23.7 F. It really doesn't look like I've lost much snow cover from my front lawn, which faces south. If I get up close to 30 on Friday I'll definitely lose some from the front. However, my backyard has lost virtually nothing since Sunday since the majority of the yard faces north and gets almost no sun still in late Jan.

I've just cracked the 20 degree mark for the first time in 85 hours.

I was zero degrees at midnight and hung out around there for most of the night until near 6:00am when i dropped below zero down to -4 at 7:30am. Amazing 3 nights in a row. I'm back up to +5 F now with clear skies and sunshine and almost no wind.

Well, I honestly did not expect to go below zero for a third straight night. However, currently (at 10:50pm) under clear skies and calm winds my temperature has dropped to -0.4 degrees F. I'm actually ahead of last night in the race to the bottom. My backup station is currently reading -1.1 F. The stations are located roughly 20 feet apart in my backyard. Both temperature sensors are 6 feet off the ground, so I consider both readings valid although my primary station has been the one with the slightly higher lows. My forecast for tonight was for mostly cloudy skies and a low of +4 F. I'm thinking the most likely thing to hamper the radiation would be clouds to roll in at some point before dawn. As of now I'll place my predicted low in between this morning's -9.8 and Tuesday morning's -3.6 and go for a low of -6.0. Assuming I remain below zero at midnight and record a low temp below zero, this will be the longest continuous stretch of sub-zero low's I've ever recorded at 3. The only other possible date this might have happened that I can't remember would be January 1994. But it seems to me that I only had 2 nights. Other than 1994 I know I've never had more than one consecutive night below zero.

Congrats! My low this morning was -9.8 F. This temperature is the coldest reading I have ever recorded in my life on my own weather station(s). The previous coldest reading I had recorded was -8 F which was at my home in NJ in Jan, 1994. I also recorded -8 F in Jan of 1985 at the same site. The coldest temperature that I stood outside in was at a friend's house in Haverhill, New Hampshire, which was -17 F. I think that was in Jan of 1992. I've now recorded 2 events (in the past 3 months) that were personally all-time records. The first was the driest month, which was from October, 2024 with only 0.42". The second was my low temperature today. My all-time highest temperature was 102 F, also recorded at my NJ home in July of 1977. I've recorded 101 degrees multiple times at multiple sites both in NJ and PA. Last year the highest max temperature here was 100 F.

Fear not...I'm pretty sure those clouds will move out at some time during the night (according to MAG), so you should still have a shot at a plunge before sunrise.

The bottom has literally dropped out from the outdoor temp. At 7:00pm I was 9 degrees. Now, one hour later I'm down to +4.3 F. That's nearly 5 degrees in just one hour. Looking to drop below this morning's low of -3.6 F. At the rate it's currently dropping I may be down to zero before midnight.

Incredible lows scattered around up in the Blain (Perry County) area (and others but these stood out on Wundermap) with readings of -14 to -17 around 7:00am. This was my coldest low temperature since Jan 2018 where I got to -2. I dropped to -3.6 F degrees around 7:00am. I was already down to -2 at 3:00am and then it began fluctuating up and down several degrees either side of zero. I have a second backup sensor located about 20 feet away from my primary station and it dropped to -4.7 F. Officially I go with my main station data regardless. The -4.7 was only 1.1 degrees colder than my official -3.6 F, so it's not that big of a deal. I'm surprised to see clouds early on. That would have interfered with the lowest temperatures. Will we be able to do it again tonight or will there be winds?

Hi Guys. Sorry, I forgot to enter my readings from yesterday's (Sunday's) snowfall. I had multiple measurements between 3.6" and 4.0". The snow melted down to 0.27". If I go with 4.0" and a melted amount of 0.27", that produces an SLR of 14.8 : 1. I'm afraid my board suffered from compaction despite being in the shade the entire day and temps in the upper teens. The total snowfall may very well have been 5" or even a bit more. My measurement, taken almost 24 hours after the end of the accumulating, definitely compacted, but I can't tell precisely how much compaction. Nice to see many surrounding stations reporting temps in the single digits, with even a few below zero already (as of 12:45am), such as York reading -9 F. Winds have barely played a factor so far with nothing more than occasional speeds of 2 to 4 mph. I'm currently down to +5.2 degrees F. My NWS forecast low is minus 1. I'm pretty sure I'm headed down to zero or below over the next 7 hours. I'll be back in the morning with my low temp.

Down to 6.6F for my low (remotely accessed). Currently up to 7.7 F. Temps are all over the place around here. I seem to be amongst the coldest. Many readings in the teens. The winds haven't arrived yet, or I would never have dropped as low. Talk to you all later when I'm back from DC.

There were no reports from me today because I was in Vermont over the weekend for a wedding of one of my nephews. Grafton was the small town. It was beautiful seeing all the frozen creeks covered in snow. It's been so long since I've seen frozen rivers, etc. Because I knew the storm was coming I was able to come back from BOS on an earlier flight that got into DCA at 3.45. Very lucky because it was still raining there as we landed, however, 15 minutes later the change over to snow hit and the snow intensity shot up so quickly. It was so heavy I couldn't find my car in the extended parking area. Easily 2"+/hr rates for a time. I'm staying over with my son in DC and will be driving back to Carlisle tomorrow morning. Based on my front doorbell camera I can estimate that at least 6" fell at my house. My snowboard should have a pretty accurate total waiting for me to measure. The intense rates didn't last all that long in DC, but I was watching a few of those intense bands on radar that passed through Carlisle. Sorry I missed that excitement. I'm thrilled for everyone else that ended up with more than expected. I'm looking forward to dropping below zero on Wednesday and Thursday mornings. A six-inch snowpack will do wonders combining with radiational cooling. That coldest temp I have ever recorded in the 24 years I've lived in the Carlisle area is -5 F, which occurred twice at two different homes. The first time was right after PD II in 2003, and the second time was after the 40" of snow I received during the first week of February of 2010. I'll be back with my update tomorrow (Monday) afternoon.
