I’m jealous. Been mostly cloudy up here all morning and mild. Hoping we can get some sun up here for a bit. I’m gonna be out west for a couple weeks so I’d like to see/hear some storms prior.

lol we are gonna be more than halfway through our avg 90-deg days before the end of June.

Cell developed rapidly NE of Wilmington, DE. and is moving right up I-95 towards Philly.

Brief shower, just enough rain to wet the laundry I had hanging outside

IL had 20+ tornado reports yesterday, and the state is now over 190 for the year (*reports*, not actual tornadoes, there are duplicate reports in this total).

 

Attached is a map for the bigger state totals through 6/19.  The disparity is amazing.  Why IL only so much more?  It's not like when an area is soaked or buried repeatedly w/ rain/snow.  That is more on the synoptic level and areal coverage is larger.  When you get down to a local level, such as an area that is about avg size for a U.S. state, that's not the same for scale.  And to get tornadoes, it is a lot more conditional (harder) than say a lot of heavy rain or snow over an extended period.

 

But given the vagaries of the atmosphere/patterns and given enough time, you are going to see things due to the law of large numbers and averages.  Just pointing this out b/c some try to assign a specific meaning or cause, where sometimes there is none.

 

Yes, I know of the hypothesis that tornado alley is shifting E, but we really do not have enough solid data IMHO.  Tornadoes, esp. weak and short-lived ones, were severely under-counted prior to the 1990s since storm chasing was not yet mainstream, WSR-88Ds did not exist for operational use, nor did the Internet (at least in widespread use).  ~35 years of data is not enough time to establish a trend either way.  I would argue that it wasn't until 2010 or so when we started to get close to actual number of tornadoes that occur every year in the U.S. w/ the  advent of the smartphone and dual-polarization radar.

Clouded up over here in the past hour.  Stay vigilant.

When I flashed a Storm Alert to my 1000 patron Newsletter at 2:23, I increased my POP for tomorrow from 25% to 60%.

Lo and behold, when Sterling revised with the afternoon package at 3:00, they increased their POP from 20 - 60% for tomorrow.

My call had nothing to do with skill or expertise. But, 5 models cannot be denied!

Hopefully, El Nino is beginning to knock.

finally a storm that is blowing up right over the city

My luck finally ran out: I had to walk home through the heaviest part of the insane monsoon flooding cell in central Fairfax County.

Never again!

was picking up my daughter from camp on the bus and we missed it by about 10 min thankfully.

 

DCA hit 95F before this started coming through, so another 95F+ day in the books.

Visibility down to about 1/2 mile in the downpour near DCA. edit: now more like 1/4 mile.
