WEATHER53 Posted July 19 Share Posted July 19 The 80’s had some doozies. 1980 was king and then 2010 rivaled it and 2011 and 2012 beat it. MN might know . I think 1980 might still have record for most 90+ in a row? The averages for 11 and 12 were unique and one of those had 7 100’s with one station but I forget with 11?

WEATHER53 Posted July 19 Share Posted July 19 Two nights ago at 9pm it was 95 and heat index 102. That’s top 10 stuff Tonight the 18th at 9 it’s 78 and feels like it. Link to comment Share on other sites More sharing options...

Strong +EPO patterns often flip after a 7-12 day phase, this is what's happened the last few days. Link to comment Share on other sites More sharing options...
MN Transplant Posted July 19 Share Posted July 19 We have a heck of a model battle shaping up for Saturday. GFS - high in the low/mid 70s with clouds Euro - high in the upper 70s with some rain NAM - high in the upper 80s, mix of sun/clouds HRRR - high in the 90s with clouds and later day rain NWS is going low 80s with a chance of afternoon rain. 3 Link to comment Share on other sites More sharing options...

The averages for 11 and 12 were unique and one of those had 7 100’s with one station but I forget with 11? 1980 and 2010 were remarkably similar. Both ended up with 67 days of 90+. 1980 has 5 100s and 2010 had 4. The average high for the days that hit 90 were within a fraction of each other. In 2010 the heat started early with a couple of 90s in the first week of April, while in 1980 it stretched on with 14(!) 90+ days in September. 1980 did have the 21-day 90 streak which I believe still lives as the longest. Here's my disturbing heat stat, though. Only 4 years in the entire DCA climo record have had 4+ days where the total temperature (high + low) is 180, or a 90.0 average. 2011 2012 2016 2024 Link to comment Share on other sites More sharing options...

wxdude64 Posted July 19 Share Posted July 19 First sub 80 high here in a while, 79.1 high! Another 0.23 in gauge this morning, about 6 tenths in last 3 days. Some relief, but more is needed.

kgottwald Posted July 19 Share Posted July 19 14 hours ago, Stormchaserchuck1 said: Looks like they are holding onto a +EPO again. To clarify, +EPO pattern (cold anomaly over Alaska) is different from the global warming trend. It's the top index-pattern for warmth across the US. The +EPO correlation to -PDO has been strong over the last few years. The -PDO has its highest correlation in the Fall, so if this forecast hold, we can very well expect a warmer to much warmer than average Sept-Nov. First September with no lows under 70? First October with an average low above 60 at DCA? Link to comment Share on other sites More sharing options...
Kmlwx Posted July 19 Share Posted July 19 Low of 70.5 and that's where I'm sitting right now. Dew in the mid 60s feels worlds better than 75+ Link to comment Share on other sites More sharing options...

Shocker, I know, but overnight guidance got less enthusiastic with daily showers and storms this coming week. A lot of too far north or too far south. Still several days to go, but summer trend would be to get screwed. 1 Link to comment Share on other sites More sharing options...

That winter still holds the record for least snow in Boston! Just 9.0 inches, of which 4.4 inches fell in November. 2011-12 and 2023-2024 are not far behind, though, with 9.3 and 9.8 inches respectively. DC's total was 20.3 inches, of which the snowiest month was March with 11.1. 2 Link to comment Share on other sites More sharing options...

stormy Posted July 20 Share Posted July 20 Light rain begins with 70 degrees. The GFS gives me .08" during the next 24 hrs. and the ECMWF gives .26"................ .43" so far for the first 20 days of July. Normal would have been 2.80". Link to comment Share on other sites More sharing options...
wxdude64 Posted July 20 Share Posted July 20 So, for the second out of last three mornings I woke up to wetness and water falling from the sky! Just 0.04 in gauge at 7 am reading, but I'll take it!
