There's a Wind Advisory up for the entire state and I have been watching the line as it moves across and it looks like it has diminished a bit but then it might do its final downsloping as it approaches the area by maybe midnight, and re-fire into a stronger line. SPC DY1 has us still as "marginal" - And I agree that it has been pretty gusty the past couple hours but the temps have held in the mid-60s too. It's currently 64 with dp a juicy 61. 1 Link to comment Share on other sites More sharing options...
ChescoWx Posted December 11, 2021 Share Posted December 11, 2021 No record high so far here in Chesco "only" made it to 62.4 (record is 68 in 1897) - though close to just 6 years ago when on this date in 2015 we hit 63.1. High wind gust so far today 30.2 mph on Tempest and 24 mph on the Vantage Pro with .05" of rain so far Link to comment Share on other sites More sharing options...
Hurricane Agnes Posted December 12, 2021 Share Posted December 12, 2021 Looks like the convective line is reforming as it is approaching the area. Am getting some light rain here (had 0.10" earlier this morning from the morning round) and am now up to 0.12" for the event so far. Temp is 62 with dp 59.

KamuSnow Posted December 12, 2021 Share Posted December 12, 2021 Severe t'storm warning here. No thunder or lightning, kind of calm at the moment, but radar says it'll be here within 5 minutes.

JTA66 Posted December 12, 2021 Author Share Posted December 12, 2021 That was quick, pretty much over with here. Just your typical squall line -- gusty winds and a 15-minute downpour. However I do hear sirens, so something in the neighborhood happened. Link to comment Share on other sites More sharing options...

Hurricane Agnes Posted December 12, 2021 Share Posted December 12, 2021 Getting moderate rain, just over 1/4"/hr - 1/3"/hr but nothing extra windy beyond what has been going on the past couple hours. Looks like the line broke up over me. Not picking up any convection either. Have 0.25" total in the bucket so far. Temp is 60 with dp 59. Link to comment Share on other sites More sharing options...
Kevin Reilly Posted December 12, 2021 Share Posted December 12, 2021 Media, Delaware County Squall line here pretty much fizzled as it went through 8 minute downpour wind gusted to about 20-30 nothing out of the ordinary with the exception of warm 60's today.

Ralph Wiggum Posted December 12, 2021 Share Posted December 12, 2021 On 12/10/2021 at 11:37 AM, The Iceman said: 12/19-20 may be something to watch for a thump to light rain event. Temps are marginal but with a strong high in quebec, the set up could easily yield a solid thump especially for NW areas but even 95 could see some accumulation with some slight adjustments mainly to the SE ridge. If the front on next thurs/fri can beat it down a bit more than progged, it may be the first real threat of the year. Still in the day 8-9 range so a lot can change obviously but something to keep an eye on. On 12/10/2021 at 6:11 PM, Ralph Wiggum said: Week of the 20th has some good potential. Wouldnt be at all surprised to see a larger storm somewhere in the East during that week leading up to Christmas. Southern energy rolling across, active PJ being forced South as the PNA pops briefly and ridging enters the eastern NAO region. Euro/GFS family of models all over this threat: Big changes on the ens for the week of the 20th. The @The Iceman thump to rain on the 20th still possible but looks like models have moved this threat up in time to the 19th with vorts racing thru the flow. Not clear how much cold air will be available at the onset....setup seems very marginal for now but certainly something to watch. The followup longwave pattern/system around the 21st/22nd holds potential and has me more intrigued as it is dependent on a rare Nina southern piece of energy meandering across the US via the STJ. Models are all over the place with the handling of that wave.....GEPS/CMC want to keep it in tact but zip it along the STJ with a zonal flow. The GEFS absorb the wave into the PJ and ride it to the West of us. GEFS do have some decent members that show the potential if the timing and wavelength play in our favor. The Euro is probably the closest in popping a big storm as it keeps the wave somewhat in tact and tries to amplify it via phasing along the Mid Atl coast....something a few of the GEFS portray. The EPS have it but not quite as enthused on the means tho I am sure there are some hits on the individual panels...haven't checked. Lots will change and much is dependent on the PNA ridge popping and how deep the NAO ridging becomes and the location of said ridging. Link to comment Share on other sites More sharing options...
The Iceman Posted December 12, 2021 Share Posted December 12, 2021 I think the most impressive thing about the record highs yesterday was that there wasn’t an ounce of sunshine at least in my area. It was cloudy all day. If we had gotten the sun out, places probably would of hit 80. 1 Link to comment Share on other sites More sharing options...
Ralph Wiggum Posted December 12, 2021 Share Posted December 12, 2021 OP at range but sniffing out the threat centered around the 22nd. Should start seeing more fantasy runs over the next few days. Still a signal on the ens....nothing overwhelming but a window nonetheless. 1 Link to comment Share on other sites More sharing options...
Ralph Wiggum Posted December 12, 2021 Share Posted December 12, 2021 CMC just a hair late. Probably a bomb for the fish this run. Long way out no sense picking an op apart but I will say given an historic look at Nina and STJ response, doubt the southern energy remains that far South. More likely to be weaker and more strung out farther N. Just my random musings. Link to comment Share on other sites More sharing options...
Ralph Wiggum Posted December 12, 2021 Share Posted December 12, 2021 Euro on board. Big storm for Mid Atl to New England. Haven't looked at thermals, dont particularly care much at this juncture. Small window here as the trof west/ridge se reloads. This is one way to score in a stubborn Nina pattern as the pattern reloads itself. Link to comment Share on other sites More sharing options...
Ralph Wiggum Posted December 12, 2021 Share Posted December 12, 2021 Euro...50/50, PNA ridge, neg NAO, SER keeping anything from sliding, PJ dipping, STJ vort rolling ENE. Might not be perfect and all the usual caveats apply given the range, but it keeps showing up and slowly improving. Probably a little too late to get er done verbatim this run, but plenty of time.
