aldie 22 Posted March 12, 2014 Share Posted March 12, 2014 Bigger story needs to be the temp drop and how fast that occurs. IMHO Link to comment Share on other sites More sharing options...
Ian Posted March 12, 2014 Share Posted March 12, 2014 Bigger story needs to be the temp drop and how fast that occurs. IMHOIf we don't get thunder it may hurt snow chances over the next 10 days too. Link to comment Share on other sites More sharing options...
Bob Chill Posted March 12, 2014 Share Posted March 12, 2014 If we don't get thunder it may hurt snow chances over the next 10 days too. Dangit. I'm firing up my charged particle generator and aiming it skyward Link to comment Share on other sites More sharing options...
high risk Posted March 12, 2014 Share Posted March 12, 2014 Ahhhh...the sun obs have begun. NAM is basically a dry frontal passage here with a stiff breeze well, there was never going to be a major QPF signal here, as whatever line goes through at dinnertime will be fast-moving and narrow. The simulated reflectivity wouldn't be expected to show a whole lot at 12 km either. The 4 km nest still has a signal of a squall line, although it's admittedly not as robust as some previous runs. But it's still there, and the latest HRRR has a decent line going through with a threat of lightning. widespread severe chances are likely decreased, but some sort of gusty line with a burst of rain should move through DC-Baltimore around 6-7PM. I'll consider thunder a bonus at this point. Link to comment Share on other sites More sharing options...
T. August Posted March 12, 2014 Share Posted March 12, 2014 13z HRRR has a nice line of t-storms moving through at 5 or 6-ish. Improvement over 12z. Link to comment Share on other sites More sharing options...

Ian Posted March 12, 2014 Share Posted March 12, 2014 Sun still pretty impotent this time of year compared to May or June. It helps but it's not the main driver here.. It's not going to turn it into a giant event or something. Link to comment Share on other sites More sharing options...
yoda Posted March 12, 2014 Share Posted March 12, 2014 Sun! Yeah, its peeks here and there... sky is somewhat clear. It probably won't do much... but it doesn't hurt Link to comment Share on other sites More sharing options...

Ian Posted March 12, 2014 Share Posted March 12, 2014 So, DC is pretty dry right now... Thanks. Everywhere is pretty dry. Dews matter more than RH unless you're looking at cloud bases which should be low with the line anyway. We should see them increase into the 50s still at least to DC but that's kind of marginal for severe unless you're in the High Plains. Link to comment Share on other sites More sharing options...
Disc Posted March 12, 2014 Share Posted March 12, 2014 Temp closing in on 60 here and haven't seen any sun at all yet. Dew points now in the low 50's IMBY. Visible sat. loop has clouds beginning to thin to the west. Link to comment Share on other sites More sharing options...

wxmeddler Posted March 12, 2014 Share Posted March 12, 2014 Some notes from the home wxstation: Winds seems to be picking up and temp has continued to rise (due to mixing I assume). Solar Rad was between 200-300 w/m^2 but now is up to ~500 w/m^2 in the last hour and temps have responded to that. Dews remain steady at 45F Link to comment Share on other sites More sharing options...

T. August Posted March 12, 2014 Share Posted March 12, 2014 Winds are seriously picking up already. Around 15 mph and gusting over 20 mph. Winds coming from the SW. My weather station is going to get a 60 mph gust, I can feel it lol... Link to comment Share on other sites More sharing options...
