Trouble Brewing for upstate SC? This from GSP.

 

IT/S QUITE INTERESTING TO COMPARE THE LATEST SURFACE OBS TO THE THE
MOST RECENT MODEL GUIDANCE. NAM SURFACE WET BULB TEMPS...WHICH
DEPICT THE WARMEST AND LEAST DRY SURFACE LAYER IN COMPARISON WITH
THE GFS AND ECMWF...IS VERIFYING PRETTY WELL...WHILE THE GFS AND
ECMWF ARE QUITE A BIT TOO LOW WITH THE WET BULBS. OF COURSE...THIS
DOESN/T MEAN THAT THIS TREND WILL HOLD THROUGHOUT THE UPCOMING
EVENT...BUT IT WILL BE SOMETHING TO WATCH CLOSELY...SINCE THE NAM
CONTINUES TO BE THE LEAST AGGRESSIVE MODEL IN PUSHING THE COLD/DRY
SURFACE AIR SOUTHWEST. OVERALL...SAW VERY LITTLE REASON TO TINKER
WITH THE CURRENT PUBLIC FORECAST PAST THE NEXT 6 HOURS.

All that model watching for nothing! Congrats , I just got NAM'd! But wait , a high of 50 is nothing to worry about!? I just talked to them on the phone, they said no worried, it's as expected! Whoopsie

Why is that? I've been following this thread and storm for almost a week and DP has not come up until now. Will DP dictate future precipitation (type/amounts)? Honest question.

 

Sorry just saw this question.

 

In a CAD situation (Cold air damming), the 3 most important things to observe are your temperature, dew point and relative humidity. A math equation of all 3 of these are combined together to create your wet bulb temperature.

 

More info on wetbulb can probably be found in the Weather Refrences and Newbie Info thread: http://www.americanwx.com/bb/index.php/topic/29651-weather-references-and-newbie-information/
