Interstate Posted February 5, 2014 Share Posted February 5, 2014 What is wet bulb mean Correct me if I am wrong... but it is the temperature that the atmosphere is fully saturated Here is a calculator for you http://www.the-snowman.com/wetbulb2.html Link to comment Share on other sites More sharing options...

Rhode Islander in Balto Posted February 5, 2014 Share Posted February 5, 2014 30/23 in Lauraville, and the above-mentioned 29.7/23 in Parkville. I am right in between those two obs stations. It is still 37 in downtown balt in the Mt. Vernon neighborhood. That is a seven degree difference in just the five miles between my work and my house. Urban heat island for damn sure. The Parkville station is IMBY (literally, it was an Xmas gift in 2012). Its amazing how much cooler it can be just a few miles out of the city. Still at 29.7, dp has risen a smidge to 24.3.

Ian Posted February 5, 2014 Share Posted February 5, 2014 Thanks for the ob...2 degree drop since precip started? People should prob lose 1-3/2-4 or so for a while at least. Link to comment Share on other sites More sharing options...
nj2va Posted February 5, 2014 Share Posted February 5, 2014 Hires NAM keeps me below freezing until ~5AM. Sim radar is impressive around 12-1 AM in DC. I still don't buy the NAM's temps but we'll see. Link to comment Share on other sites More sharing options...
nj2va Posted February 5, 2014 Share Posted February 5, 2014 People should prob lose 1-3/2-4 or so for a while at least. Yeah, you can see the drop well on the WxBell Hires NAM sim radar w/ 2m freezing line. Link to comment Share on other sites More sharing options...

Nothing has really changed in that regard either.. I haven't even really looked at the regular NAM but hi res looks like it has other than it being a little colder east to start and perhaps a touch colder everywhere else.. which translates of course, but we still aren't looking at any massive changes to what people have been talking about.

Yeah, I agree with your thoughts you've posted tonight on this event. I think there'll be some minor icing here but on the favored surfaces one would expect in/near a major city. Favored areas will see more obviously. Link to comment Share on other sites More sharing options...
Bob Chill Posted February 5, 2014 Share Posted February 5, 2014 Hi res is close at 9pm for me. Maybe a degree to high. Lowest is 29 at midnight. Seems possible. 32 or less until 7am. We'll see Link to comment Share on other sites More sharing options...

In terms of the forecast, nothing much has changed, but in terms of the potential impact on roads and sidewalks ect...a degree or two makes a significant difference. I think we have gone from a marginal event (in MoCo) in terms of impact, to closer to a moderate event. Link to comment Share on other sites More sharing options...

usedtobe Posted February 5, 2014 Share Posted February 5, 2014 Shoot, I thought I'd bust by being too heavy with ice accumulations. Now I think I might be light in the northern portions of two eastern zones in my article. The new nam has come in colder than the old one. Did I ever post that I hate forecasting ice storms.
