winterymix Posted February 5, 2014 Share Posted February 5, 2014 DC Peeps: Gotta move north, northwest, higher elevation with the "new normal" Notice critical freezing temps: DC is just a skoch warm. Maybe some 'mixed" at the start. Link to comment Share on other sites More sharing options...

Chase Posted February 5, 2014 Share Posted February 5, 2014 So why did LWX go with Winter Storm Warnings... and not Ice Storm Warnings? They believe there will be a period of precipitation that is not freezing rain. Link to comment Share on other sites More sharing options...
Ian Posted February 5, 2014 Share Posted February 5, 2014 just hit 32. DP is 24 and that wet bulb calc says I should bottom out at 29 if you get full saturation and no latent heat release. Link to comment Share on other sites More sharing options...
Rhode Islander in Balto Posted February 5, 2014 Share Posted February 5, 2014 Excited for another poster in this part of the city, particularly one with a wunderground station. Thanks! Been a lurker since the Eastern WX days, and though I don't know as much as some on here, I'll gladly contribute by providing quality weather data! I've had the station running for 13 months now, and gotten some great data, though I think my wind readings might be a tad on the low side (possibly a site placement issue, or maybe all my wind forecasts just bust low!). Temps still holding at 29.7, dp going down again, back at 23.4. Also going down is this 8% abv beer....a tad too quickly and smoothly Link to comment Share on other sites More sharing options...

Maybe some 'mixed" at the start. NEARFREEZINGSURFACETEMPS.gif CRITICALTHICKNESS.gif That seems way off, considering most of us are below or at freezing and we still have 2-4 degrees to potentially drop. I think we'll have a good sheet of ice on sidewalks. Link to comment Share on other sites More sharing options...
Jebman Posted February 5, 2014 Share Posted February 5, 2014 29 degrees with a 24 degree dewpoint. I hope it keeps falling, I want ICE, ICE Baby phone radar shows freezing precip breaking out all over the region Link to comment Share on other sites More sharing options...
Ian Posted February 5, 2014 Share Posted February 5, 2014 Wes.. I think you're good overall. The changes are going to mainly be to give some more people minor ice amounts. Perhaps better without the note to maybe hedge low but whateva.. close enough. Link to comment Share on other sites More sharing options...

The "freezing rain" that falls will progressively warm with or without cold air damming at the surface. Anyhow, based upon the maps posted, DC isn't getting in on much cold air damming.

snowfan Posted February 5, 2014 Share Posted February 5, 2014 http://www.spc.noaa.gov/products/md/mcd0071.gif SUMMARY...FREEZING RAIN WILL DEVELOP EAST OF THE APPALACHIANS INTOTHE NRN DELMARVA OVER THE NEXT FEW HOURS. RAIN RATES WILL LIKELYEXCEED 0.05 IN/HR. SLEET WILL BE COMMON ACROSS SOUTHERN PORTIONS OFPA THROUGH MIDNIGHT.DISCUSSION...MATURING WARM CONVEYOR WITH AN EXPANSIVE ZONE OFPRECIPITATION IS SPREADING ACROSS THE OH/TN VALLEY AND WILL SOONSPREAD ACROSS HIGHER TERRAIN OF WRN PA/WV INTO WRN VA/MD AREA.ADDITIONALLY...WARM ADVECTION ACROSS THE DELMARVA APPEARS TO BEPRIMARILY RESPONSIBLE FOR RECENT RASH OF SHOWERS THAT HAVE DEVELOPEDACROSS THIS REGION. WEDGE OF COOL AIR WEST OF THE BLUE RIDGE ISSEVERAL DEGREES BELOW FREEZING AT 02Z AND IS LIKELY ON THE ORDER OF1KM DEEP. THIS WILL GRADUALLY SHALLOW WITH TIME BUT SHOULD NOT WARMABOVE FREEZING IN MANY PLACES PRIOR TO 06Z.FARTHER NORTH...INITIAL PRECIPITATION WILL FALL IN THE FORM OFSLEET...OR PERHAPS EVEN SOME SNOW...ACROSS SRN PA. WITH TIME MUCHWARMER TEMPERATURES AROUND 2KM WILL SPREAD ATOP COOL BOUNDARY LAYERRESULTING IN SUFFICIENT MELTING FOR A SWITCH TO FREEZING RAIN AFTER06Z. PRECIPITATION RATES WILL INCREASE TO NEAR 0.10 INCH PER HOURIN PLACES AS WARM ADVECTION CREATES A FAVORABLE PROFILE FORSIGNIFICANT ICING. WBZ LEVELS REMAIN BELOW FREEZING ALONG THE I-95CORRIDOR FROM DC THROUGH BWI TO PHL.

NorthArlington101 Posted February 5, 2014 Share Posted February 5, 2014 The beltway isn't DC but which sunset are we discussing? . Sorry, had meant sunrise, and by beltway I mean inside the beltway, which includes DC. Going to stop posting and start watching everyone else fight over our .05 inches of ice.
