calculus1 Posted December 29, 2012 Share Posted December 29, 2012 A good rule of thumb is it's usually somewhere between your DP and temp. I use an addon for Chrome/Firefox which calculates it. Sweet add-on! Thanks, Burger. This is the wet bulb calculator from the table: http://www.srh.noaa....pz/?n=wxcalc_rh Don, I really liked this calculator too. With my Vantage Vue, I could input the exact values of temp, RH, and pressure into this site to calculate the wet bulb. I knew it was always some value between DP and temp, but I didn't know where exactly, Currently 35.6 over 32, which wet bulbs to 33.96. Not low enough, yet!

buckeyefan1 Posted December 29, 2012 Share Posted December 29, 2012 hmm somehow I didn't even see this thread, but posted about this event in another thread earlier today so I'lll copy and paste: It should make it easier to locate now that it's pinned Ya I know...pinning a thread for some flurries light amounts, but why not enjoy it while it lasts Good luck to everyone out west. Here in CLT we're sitting at a wetbulb of 35 which means all rain for us. Maybe we can get lucky and I'll spot a few rebel flakes. AccuPro maps didn't look bad for the foothills with around a half inch of snow for you guys. +1 Link to comment Share on other sites More sharing options...
strongwxnc Posted December 29, 2012 Share Posted December 29, 2012 Nice.. Temp 36.9 DP33 FWIW... Link to comment Share on other sites More sharing options...
CAD_Wedge_NC Posted December 29, 2012 Share Posted December 29, 2012 Somebody please correct me but, a simple "none official" way is to add temp and dew point and then divide by two. Basically meet in the middle. So 36 temp and 32 dew point would be around 34. Not quite.... A rule of thumb I use and it's pretty good is to take the difference between the temp and dewpoint and divide it by three and subtract that from your temp. For example a temp of 36 and a dewpoint of 27 would make a difference of 9, divide that by 3 and subtract that from 36 and you get a wetbulb of 33 degrees. It's simple and close enough.....

Met1985 Posted December 29, 2012 Share Posted December 29, 2012 light rain/snow mix falling now temp 34. Same here. I am at work now which is around 2800 feet so big difference than at home but temp is dropping and it has started to rain some. I am hoping with the heavier moisture coming in things drop of here at work but I am not to sure about that at this elevation. Good luck to all!

NavarreDon Posted December 29, 2012 Share Posted December 29, 2012 Wow this is really going to be close for the mountains & maybe even some in the foothills. As has been stated it is going to vary quite a bit depending on where you are at. Here is the last update from GSP. .NEAR TERM /THROUGH SATURDAY/... AS OF 820 PM EST FRIDAY...BASED ON LOCAL IFLOWS GAUGE REPORTS...ASOS REPORTS AND THE RADAR PRESENTATION...PCPN IS FALLING ALONG MUCH OF THE TN LINE ATTM...WITH AN AREA OF MODERATE PCPN ABOUT TO OVERSPREAD THE SOUTHWEST NC MTNS...NE GA AND THE WRN UPSTATE. THEREFORE I/VE RAMPED UP CATEGORICAL POPS A LITTLE EARLY ACROSS THE MTNS AND WRN REACHES OF THE FA. THE ATLANTA SOUNDING WAS STILL VERY DRY BELOW 700 MB...SO AREAS EAST OF THE MTNS...WHERE UPSLOPE HASN/T SATURATED THE AIRMASS...WILL STILL TAKE A FEW HOURS TO MOISTEN UP ENOUGH TO ALLOW PCPN TO REACH THE GROUND. BASED ON THE DUAL-POL DATA IT APPEARS THAT MIXED PHASE PCPN IS FALLING WITHIN A COUPLE THOUSAND FEET OF GROUND LEVEL OVER THE MTNS. THEREFORE...THE SOUTHWEST AND CENTRAL MTNS ARE PROBABLY SEEING A RAIN/SLEET MIX AT THIS TIME. I WENT AHEAD AND USED THE 18 UTC NAM THERMAL FIELDS WHEN RUNNING THE TOP DOWN TOOL FOR DETERMINING PCPN TYPE. THIS HAS RESULTED IN A LITTLE MORE SNOW/SLEET ACCUMULATION OVER THE CENTRAL AND NRN MTNS...AS WELL AS ACROSS THE SE SLOPES OF THE BLUE RIDGE OF EASTERN MACON...SOUTHERN JACKSON AND TRANSYLVANIA COUNTIES. I ALSO HAVE MORE SNOW/SLEET OVER EASTERN BUNCOMBE AND EASTERN MADISON. EVERYTHING IS STILL WELL WITHIN THE ADVISORY CRITERIA RANGE...THOUGH SOME OF THE SLEET TOTALS ARE APPROACHING A HALF INCH. THE ONLY COUNTY WITH ANY REAL ACCUMS NOT CURRENTLY IN AN ADVISORY IS MACON. HOWEVER...OWING TO THE SMALL PART OF THE COUNTY AFFECTED...I PLAN TO KEEP THEM OUT OF THE ADVISORY WITH THIS UPDATE. DOWNSLOPE FLOW AND WARM ADVECTION SHOULD KEEP PCPN MOSTLY LIQUID ACROSS THE HIGHER ELEVATIONS OF GRAHAM...SWAIN AND NRN HAYWOOD COUNTIES. AND THE FOOTHILLS AND PIEDMONT STILL LOOK TO HAVE PRIMARILY A COLD RAIN OVERNIGHT. A LITTLE SLEET IS CERTAINLY POSSIBLE WITH THE DRY LOW LEVELS...BUT IT WILL BE LITTLE MORE THAN A CURIOSITY.

Jonathan Posted December 29, 2012 Share Posted December 29, 2012 Sitting at 34° with a TD of 28° So Hopefully I'll be sitting right around 31-32 degrees for the fun stuff. Hopefully. The TD actually just dropped from 30° to 28° with the last observation from KMTV. Pretty excited to see how things pan out! Link to comment Share on other sites More sharing options...
