CAPE Posted July 20, 2019 Share Posted July 20, 2019 1 hour ago, Eskimo Joe said: I think the DCA temp sensor broke. Its throwing some weird readings. I know you probably said this tongue in cheek, but since there is a bit of history here about "bad" DCA sensors, I feel compelled to give my 2 cents. I highly doubt there is anything wrong with the sensor. NWS stations use high grade platinum RTDs, which are extremely stable and accurate. Any variability is likely environmental- e.g. breezes off the water. The sensor's measured resistance correlates extremely closely with the actual temperature, as a function of it's TCR. High vibration is really the only source of erratic readings, outside of something going wrong with the electronics on the measurement side, which is even more unlikely.

CAPE Posted July 20, 2019 Share Posted July 20, 2019 High temp here was 96, after 93 yesterday. Highest recorded HI was 114. Currently 92. Decent chance tomorrow will warmer, especially for eastern areas. I would not be surprised to see 97 or even 98 here. Link to comment Share on other sites More sharing options...
frd Posted July 20, 2019 Share Posted July 20, 2019 For the beach goers: very warm surf in Wildwood, and Cape May extending South to Dewey and Ocean City, MD. ( I saw some 80 degree surf temps, wow ! ) but as Mount Holly NWS points out, some upwelling further North. << it appears as though there is some upwelling along the New Jersey coast, mainly from Long Beach Island down to the Atlantic City area. Water temperatures right along the shore are in the middle and upper 60s in spots. >> Link to comment Share on other sites More sharing options...
Sparky Posted July 20, 2019 Share Posted July 20, 2019 High today reached 94 after yesterdays 93. Not the hottest of heat waves, but the dews have been between 74.3 and 76.8 throughout if my sensor is correct which adds a bit of discomfort for sure.

WinstonSalemArlington Posted July 20, 2019 Share Posted July 20, 2019 As of 5 PM, Norfolk has reached 100 degrees for the first time in 2 years! (Last 100 degree day: July 14, 2017). Other noteworthy high temps across the region: Richmond 98, Salisbury, MD 96, Elizabeth City, NC 96. #vawx #ncwx #mdwx #heat 1 Link to comment Share on other sites More sharing options...

Inverted_Trough Posted July 20, 2019 Share Posted July 20, 2019 BWI needs to calibrate their thermometer. They've consistently been 1-2 degrees higher than DCA this summer. For once, DCA's sensor actually seems to be working fine. Link to comment Share on other sites More sharing options...
pazzo83 Posted July 21, 2019 Share Posted July 21, 2019 got to 101 in west end did anyone notice the quick drop to 84 in the 3pm hour (3:45 i believe) at DCA? Is something up with their sensor (they've also been running a couple degrees cooler than most of the PWSs in Arlington and the District just across the river) Link to comment Share on other sites More sharing options...

Feels hotter out than at 4 or 5 pm due to no breeze. 2 Link to comment Share on other sites More sharing options...
Kmlwx Posted July 21, 2019 Share Posted July 21, 2019 I was just driving down to my parent's house from Columbia and when I was heading west on the ICC I saw the big storm in the distance...I always underestimate how far you can see in the sky. I figured it was in MoCo already - pulled up Radarscope and saw it was still out along the Blue Ridge. Looks like it's falling apart now. Might not bring any relief to areas east. 1 Link to comment Share on other sites More sharing options...

pazzo83 Posted July 21, 2019 Share Posted July 21, 2019 storm basically died as it moved over the District - dropped me down a few degrees to 87 with some sprinkles, DCA looks like it wasn't really affected - 91 at 10pm. Link to comment Share on other sites More sharing options...
dailylurker Posted July 21, 2019 Share Posted July 21, 2019 Terrible out there. Went out to take my "medicine" and a short walk. Broke out in a light sweat in 10 minutes. It sounds and feels like a jungle. Link to comment Share on other sites More sharing options...
arlwx Posted July 21, 2019 Share Posted July 21, 2019 LWX needs to check the 3 day obs pages. At 335 am, all of those pages were reporting the just-before-6 am obs! Somehow, I think a programming glitch has moved the listed times ahead three hours. ((The "more local weather" summary had the correct times.))

CAPE Posted July 21, 2019 Share Posted July 21, 2019 Forecast high is 99 for today. With a bit more of a westerly wind, might get close. Actual highs have been 2-3 degrees under the forecast so far. Today should be the hottest of the 3 days (here). I will go with 97. Link to comment Share on other sites More sharing options...

I was watching the lightning show from Columbia on Saturday evening, 9:00ish. It was flashing at a quick rate off to my W & SW, but storm traveled SE-ward toward N-ern part of DC. Nothing more here than a distant light show. Temps in MBY ranged from 78 to 96 on Saturday. Sunday morning low as of 6am is 79, pretty toasty for the 'burbs.
