Looks like the warm water helped keep DCA (and a few other spots "on" the water) well short of freezing. A few other locations may also have escaped. But IAD hit 27, BWI 30

24 for the low.

It was 40F at 3am in Colonial Beach so I was like no way. Surprised to wake up to see 32 at 630am! Winds must have died down.

32 on the dot along the former, and sure to be future tropical shores of the Potomac.

24 currently… plants that have opened hopefully will recover.

23 this morning,. I wonder how much damage this hard frost and freeze did to the fruit trees and other vegetation overnight?

31.8 for the low... already back above freezing.

30 Ridgely Mesonet reporting 28

24 for the low here

29.3 so far.

FWIW, the April dynamical mean is up to 2.06 for the ONI. This is significantly ahead of 2023 and 2016 at the same point. 2023 was at 1.54 and 2.10 verified. April 2015 was at 1.30 and 2.80 verified. So for the 2 most recent strongest El Niños the spring forecast barrier resulted in too weak a forecast. https://iri.columbia.edu/our-expertise/climate/forecasts/enso/current/ April 2026 Average, Dynamical models 0.764 1.120 1.438 1.709 1.763 1.951 2.060 1.856 1.810 April 2024 Average, Dynamical models 0.460 0.785 1.098 1.328 1.406 1.481 1.547 1.473 1.386 April 2015 Average, dynamical models 0.8 1 1.2 1.3 1.4 1.3 1.3 1.3 1.1

22.7° what a morning

Don’t see the Pope’s tropical forecast for NNE.

25.7F this morning in Lancaster. .

Very important to remove the station changes in Chester county. The county stations moved frequently and bigger changes were cooling. The station population has cooled with time mainly due a shift from towns to more rural sites. Our older stations are warmer than the county as a whole, particularly in the 1930-48 period when Phoenixville was much warmer than other local stations on summer afternoons; and, West Chester and Coatesville were in built-up towns. I can match NCEI perfectly by; 1) excluding the 3 big station moves: Coatesville in 1946+48, Phoenixville in 1948 and West Chester in 1970; and, by removing the temperature difference between stations by taking station anomalies to a common period. Raw data without the contamination of station changes. The chart below shows that NCEI has met their objective of taking out station changes to reveal the weather and climate signal in the raw data. Of course, if you leave in all the station changes you won't match NCEI or any other scientific analysis. This thread is a strawman based on bad analysis and confirmation bias.

6z gfs has temps in the 40s with rain on Saturday. Disgusting.

27 when I left the house, could yet inch lower. Color me impressed. Also had a trace of rain yesterday. Carry on.

23 we freeze don't worry the heat will be here soon enough and ill be crying

30.2

Bring it!!!! I'm still sceptical though. It is nice to see a change in pattern though. I can't believe how brown it is around here. We basically just got out of dormancy here, and went right back.

White Plains saw the temperature fall below 30F (-1.1C) this morning. The last time it got at least as cold this late in the season was April 23, 1982 when the low was 26F (-3.3C). The low of 28F (-2.2C) broke the daily record of 29F (-1.7C) from 1981.

Another frosty morning

30-31 around my neighborhood
