mappy Posted November 25, 2014 Share Posted November 25, 2014 hovering between 31-33 DP at home, changes often every time I check my PWS Link to comment Share on other sites More sharing options...
Eskimo Joe Posted November 25, 2014 Share Posted November 25, 2014 Couple of side items to pay attention to: 1.) Highs are running 1-3 degrees below what was forecast. 2.) Dew points are running lower than what MAV/MET MOS guidance was forecasting. This is huge, especially if the dews can drop another 3-5 degrees overnight. The atmosphere will be able to wet bulb much quicker. 3.) The cirrus shield has really muted the insolation on roads...secondary roads should see some adverse impacts. 4.) Speaking of clouds, there is a nice bit of clearing in western PA / eastern OH. If that can nudge in for a few hours this evening then it should help temps radiate.

T. August Posted November 25, 2014 Share Posted November 25, 2014 55/33 with some clearing taking place. Considering my station is 20 ft away from the inlet, the DP is very good right now. Link to comment Share on other sites More sharing options...

Yeah, I'll back up these points as well. All of these points seem subtle but could make a very big difference. Also, It will be interesting to see how if there are still some breaks in the clouds during the evening hours, which would allow temperatures to continue to drop somewhat.

EastCoast NPZ Posted November 25, 2014 Share Posted November 25, 2014 forecast high of 55F today. Hit 57F. Interestingly, we are under 95% sunny skies. Explains the temp bust, and will be interesting if it persists long enough to get us quick radiational cooling before the blanket is put back on us. Each degree is going to be critical for us.

When you have radiational cooling like you describe, is the theory that once the temps drop they get locked in once the cloud cover comes back so we would be a few degrees colder than forecasted?
