Ian Posted July 17, 2012 Share Posted July 17, 2012 Lower humidity today? well, i sorta knew that answer but it's not consistent imo... then again few nws products are Link to comment Share on other sites More sharing options...
wxmeddler Posted July 17, 2012 Share Posted July 17, 2012 Storms should be a little later get going today, not as cool mid-levels as yesterday. Isolated showers to start around 2pm but then quickly falling apart as low shear and water loading take over. Dry air around 700mb might cause some local weak microbursts when any sustained convection collapses. Mountain circulation based storms will have the best chance of sustaining themselves. In other news: The RH is down in the 30's! Link to comment Share on other sites More sharing options...
MN Transplant Posted July 17, 2012 Share Posted July 17, 2012 well, i sorta knew that answer but it's not consistent imo... then again few nws products are If you look at the hourly graph, they only have the HI hitting 101 or 102 today. 107 tomorrow, so I bet we do see one for Wed.

H2O Posted July 17, 2012 Share Posted July 17, 2012 don't quite get why no heat advisory today... i guess it'll be borderline but can't recall many days with highs forecast near 100 without one i know they discussed the possibility a couple days ago and surprised they have yet to pull the trigger.

H2O Posted July 17, 2012 Share Posted July 17, 2012 Oh, and good news/bad news. Good news is that I just got a new work computer with a functioning IE8, bad news is that I am posting wxside more now Link to comment Share on other sites More sharing options...

wxmeddler Posted July 17, 2012 Share Posted July 17, 2012 Hit 98.5 so far today, the dry air is making an impact. Shortwave radiation doesn't have to waste energy on heating extra water in the air. Link to comment Share on other sites More sharing options...

Bob Chill Posted July 17, 2012 Share Posted July 17, 2012 I have a bad sensor in the AC in my truck and the damn thing shuts off when at idle for a 5 minutes or so. Bad traffic inbound 267/66 in the workzone at noon and off goes the AC. Good grief did it get hot with the quickess. I really don't mind heat all that much but I gotta be honest here. It's been a roaster ever since the nice June pattern went away. I'm getting sick of sweating my eyeballs out. I'm going to NYC this weekend and it's supposed to be 82 on Sat. I may have to bring a jacket. Link to comment Share on other sites More sharing options...

RodneyS Posted July 17, 2012 Share Posted July 17, 2012 DCA got to 96 so we have that Speaking of which, I just noticed a real oddity for the last two days (July 15-16) at DCA: High temperature each day of 96, low temperature each day of 76, and precipitation each day of 0.02 inches. I've checked back to 2000 and can find no other consecutive days at DCA where the high and low temperatures, as well as measurable precipitation, were exactly the same each day. (I emphasize measurable precipitation because I have found a couple of days with a trace of precipitation each day and the same high and low temperatures.) Does anyone know of a similar situation in the past? Stat geeks want to know. Link to comment Share on other sites More sharing options...

MN Transplant Posted July 17, 2012 Share Posted July 17, 2012 July 1930 had 6 100° days in DC. We could tie that tomorrow. Link to comment Share on other sites More sharing options...
Ian Posted July 17, 2012 Share Posted July 17, 2012 now tied for 3rd for most 100+ in a yr. 7 is second... then the long haul to 1930's 11, still seems unlikely but perhaps possible Link to comment Share on other sites More sharing options...
