blackngoldrules Posted January 11, 2017 Share Posted January 11, 2017 Stay safe. Roads are horrible this morning. Yeah, they are pretty icy in spots. Air temps are well above freezing but ground temps certainly aren't. Maybe the NWS should think about adding ground temps to their stats. People see that temps are in the upper 30s or around 40 and just assume things should be fine. A morning like this could catch you off guard.Sent from my SM-G920P using Tapatalk Link to comment Share on other sites More sharing options...

I was wondering what you were talking about....It was 41 degrees. Driving in saw a kid bit it hard running down his driveway in USC. Pulled into parking lot at work and was able to literally skate the whole way across the road to my building. Link to comment Share on other sites More sharing options...
colonel717 Posted January 11, 2017 Share Posted January 11, 2017 30–day from CohenThe latest polar cap geopotential height anomalies (PCHs) plot (Figure 10) continues to show normal to warm tropospheric PCHs and cold stratospheric PCHs. There is a pulse of the upward Wave Activity Flux (WAFz) or poleward heat transport predicted over the next few days (Figure 11) that is just strong enough to warm the stratospheric PCH back to near normal. However for next week more below normal WAFz results in a cooling stratospheric PCH. Therefore the stratospheric AO is predicted to remain neutral to slightly positive over the next two weeks (Figure 1). The WAFz pulse predicted for this week does result in warming and ridge building over the North Atlantic sector and Europe (Figure 12). This causes the stratospheric PV to elongate resulting in cross-polar flow directed at eastern North America. Normally I would interpret this as favorable for cold in the Eastern US but the weather models are predicting just the opposite with no change in the pattern. For the following period the stratospheric PV forecast is predicting further disruption with the possibility of a Canadian warming and northwesterly flow directed at the Northeastern US. This is even further favorable for cold in the Eastern US though no signs for cold in the Eastern US are suggested by the weather models. If there is a robust stratospheric PV disruption it typically takes about two weeks for the resultant circulation changes to reach the surface so potentially the signals for cold are for beyond the forecast period of the weather models. As I have discussed previously we run daily a stratospheric PV forecast model. It forecasts the PV strength to peak now and then slowly weaken, bottoming out the fourth week of January. The model is highly speculative and is known to have a high rate of false positives of sudden stratospheric warmings (SSW). The weather models are certainly suggestive of a SSW but even the model forecast I would consider highly uncertain. If a robust SSW does occur, that could potentially force a more persistent cold across the NH, especially North America where the cold has been more transitory than Eurasia. If no SSW occurs, then I would expect the weather to continue to be sensitive to variations in the atmospheric circulation especially along the eastern edges of the ocean basins. One last alternative is if the tropospheric and stratospheric PVs couple with both in a strong phase then mild weather could become more persistent across the hemisphere.

MikeB_01 Posted January 11, 2017 Share Posted January 11, 2017 Crazy how icy it is out there. I would have thought that with the amount of time yesterday way above freezing, that the ground temps would be above it. I would also like to see the NWS add ground temps to there stats. Though it probably only has an effect on people on days like this. Link to comment Share on other sites More sharing options...

CranberryWX Posted January 11, 2017 Share Posted January 11, 2017 The Weather Channel this morning was pushing a potential for a freezing rain event from Texas to WV and possibly into southern PA. Also showing 1 to 3" of snow later Saturday afternoon/evening for southern PA. Depends on where the front lines up and how much cold air stays in place at low levels. NWS Pitt is also mentioning the potential for Freezing rain/mix precip in their discussion for Saturday. Link to comment Share on other sites More sharing options...

Rd9108 Posted January 12, 2017 Share Posted January 12, 2017 Waste of 25$ for the weatherbell subscription. Hopefully GFS isn't off its rocker and we can at least have a chance at a moderate event and maybe a warning criteria. Link to comment Share on other sites More sharing options...
CranberryWX Posted January 12, 2017 Share Posted January 12, 2017 I was expecting to hear spring peepers this morning when I let the dog out. There is a mother lode of rain stretching back through Indiana heading this way. With the positive tilt of the line and the way it is moving along its axis, we're in for lot of precip today. My yard still has some frost left in it which will cause more runoff than usual. Link to comment Share on other sites More sharing options...

I think the 6z GFS had close to an inch of rain for KPIT, and when the cold front moves through this evening could even be thunder... Just checked the NAM for this weekend and its showing some snow now, maybe an inch or so. Not sure how accurate that is though and it might be counting slop as all snow. I don't think ZR would be a major impact given marginal temps, antecedent surface temps from today's warmth, and happening during daylight combined with the fact the high will be moving out we should see mainly plain rain after the change over unless things change.

What you don't want to pay $25 to track rain showers...Looking like pattern change is being pushed back to end of month now. See a lot of mets excited for Feb. If we have to wait that long, give me at least some 60's and sun thrown in until then. Link to comment Share on other sites More sharing options...
