SilverFallsAndrew Posted August 28, 2023 Report Share Posted August 28, 2023 I was just looking at the January 20-April 20th period at SLE. We forget the last half of January was actually pretty chilly down this way. 12 of the last 13 days of the month were below normal at SLE. SLE had a 25 day stretch from February 21-March 17th where every single day was below normal and 29/31 days in March. All in all 75 of 91 days were below normal in the Jan 20 -April 20 stretch. This 91 day stretch was the 7th coldest on record at SLE for that stretch, tied with 1976, and it was the first time since 1976 we had a year that was in the top 10. If you look at the past 91 days, we have seen 65 days above average days by comparison. By comparison the past 91 days ranks 3rd all time behind 2021 and 2015, and just ahead of 2022.

TT-SEA Posted August 28, 2023 Report Share Posted August 28, 2023 Obviously a really strong inversion in place today as the convection aloft has not disrupted the low level marine layer at all. I also think smoke trapped under the inversion is enhancing the low clouds today. Really looking forward to clean air starting tomorrow. 1 Quote **REPORTED CONDITIONS AND ANOMALIES ARE NOT MEANT TO IMPLY ANYTHING ON A REGIONAL LEVEL UNLESS SPECIFICALLY STATED** Link to comment Share on other sites More sharing options...

Convection can be such a fickle thing but this is an absolute classic set up for thunderstorms with heavy rain and frequent lightning. We may end up being just slightly west of the heaviest rain with the storms overnight…but we will make up for it during the day Tuesday and into Wednesday most likely. Plus this weekend into next week is trending wetter with additional systems. Fall is coming in. 2 Quote Link to comment Share on other sites More sharing options...
