The sensor isn’t that close to the runway. The river temperature this morning was 58 degrees just upstream. 2 1 Link to comment Share on other sites More sharing options...
TSG Posted October 28 Share Posted October 28 2 hours ago, WEATHER53 said: People will defend DCA to the death It doesn't need to be defended. The multitude of times it's been discussed has provided plenty of evidence that it's accurate to its local environment. The issue is people not understanding what that local environment consists of and causes in terms of microclimates. All you have to do is look at the dewpoints to see the river influence.

Low dews last night: IAD - 28 BWI - 30 DCA - 37 Except that when the River is frozen it still happens . When it’s snowing heavily throughout the entire area it still happens. When it’s quite windy it is much less in order on of 1-3 degrees because the air mixes So something g there is preventing both radiation and mixing and it’s not the river nor the GW parkway. Couple of local guys who live in apartments can’t mix or radiate either because they don’t have a lot fir their equipment but rather a patio/balcony . The thermometer at DCA Is accurate for the 8’ by 8’ area which it occupies which is skewed. 50’feet away entirely different and Stan Rossen deployed many thermometers in a test about 25 years ago and consistently measured 5-10 degrees cooler as close as200’ away 1 Link to comment Share on other sites More sharing options...
WEATHER53 Posted October 28 Share Posted October 28 In my 45 year observation of DCA the discrepancy between it and BWI and Camp Springs and my station is as follows for spring, fall and winter. Clear, windless night with average or lower humidity = +7 to +12. Cloudy =+5 to +10 Rain-=+4 to +8 Raging snowstorm=+3 to +4 Vey windy: 20 gusting to 40 all night+2 to +3 , There are a lot of theories. .

LongRanger Posted October 28 Share Posted October 28 BWI again 4 degrees colder than my station. For decades, my station's daily mins have routinely been 1 to 2 degrees colder than BWI. That all changed suddenly when Mr Freeze took up residence at BWI this month. Link to comment Share on other sites More sharing options...

The month of October 2000 logged only 0.02 inches of rain and was the middle of a very long dry streak. In total, 0.02 fell across 43 days spanning September 26 to November 9. But officially, the longest streak without rain that year was 21 days. Their reporting in this article would agree. https://www.washingtonpost.com/weather/2024/10/22/dc-dry-streak-drought-lanina/ 2 Link to comment Share on other sites More sharing options...
