All Activity

Some activity as the season gets into its peak period

I was driving through it on I83 in York. Epic shelf cloud and then whiteout rain

We had a few small pea size fall too

That quick warm up in early spring is another parallel to 2009-2010.

Seeing subtle signs of a 'back stressed' summer synopsis. Not personally ready to go 'breaking', per se. I mean solar max ends only just today. These things take time. In fact, we had cooler last month in July for a stretch. However, in the general super synoptic aspect/layout the summer polar branch of the westerlies appears to be sinking S of 50 N (~) latitude. This was not the case in July. July's cool down(s) was a pretty glaring example of cheating, a leitmotif this summer up here in the NE. This summer appeared to single out our region for repeating heat offsets - yes ...this, despite being above normal. It could have been much worse. I feel we can't go by that metric so much now that everything in every direction seems there's a soupcon of Gretta-taint at this point and probably forever more... We have to judge these through a relativistic lens. Having said that, heights are also still lingering around 582 DM, a summer value by convention. Still the subtle sign is both the jet coming S a bit, but also that the next heat expansion appears situating farther S across the CONUS .. ~ 120 thru 180 or so hours. This exposes our region to more fast mid level over top flow and probably ablates heat. Also in lieu of cloud and convection traffic. Heh, like trying to set up a lemonade stand on an Interstate. Beyond that into the deeper range, general climo starts to weigh -

The was the massive Atlantic ridge >594 DM parked off the Atlantic all of last week a bit to east to bring the persistent mid 90s + and strong heat has been capped since the 14th of July in the area.

1997 was easterly QBO/Low-ascending solar, so it isn't that surprising that the polar domain was more disturbed early on.

(The Weather Channel) 1943: The lightning of August 10, 1943. In the worst lightning incident in Washington, DC regional history, six soldiers were killed on a Ft. Belvoir drill field. A large group of soldiers was playing baseball, and the game had just been called due to the approaching storm. As the troops began to disperse, a bolt of lightning struck in the middle of the group. Six soldiers were instantly killed and the sudden bolt of lightning injured nine other men. (Unusual and Noteworthy Meteorological Events at Washington, D.C.) (Ref.

More than 60% of the 100 costumes for the Mummers Parade were damaged or destroyed. (Ref. Wilson Wx. History) 2016: August 9-16. Weak low pressure combined with abundant Gulf moisture produced phenomenal rainfall and flooding across central Louisiana, inundating entire neighborhoods and towns, especially around Lafayette and Baton Rouge. Rainfall totals exceeded 20 inches in as little as two days. Thirteen people died and economic costs ranged from $10 to $15 billion. 2020: Summary: A well-organized and long-lived complex of storms produced widespread severe ? wind damage across Iowa, northern Illinois, and northern Indiana during the day on Monday, ? August 10. Much of this severe wind was significant (75+ mph winds) resulting in many ? downed trees, several toppled-over semi trucks, and many communities receiving at least ? some minor structural damage. Within the broader area of severe winds, 15 tornadoes were ? confirmed across northern Illinois and northwest Indiana. (Ref.Chicago Derecho that also hit Iowa with 110 MPH winds.)

82 / DP : 67. Partly cloudy an areas of storms moving from S-Central PA to E-PA should push some clouds and showers into C-SNJ in the next 1-3 hours, otherwise warm / muggy. Day 5 of the heatwave for some 90 - 95 type day with enough sun - clouds being a caveat. The warmest / sunniest spots get a day 6 on Tuesday but many upper 80s / low 90s. Riding near - above normal - a push back warm upper 80s / low 90s Thursday in the hotter locations. Trough into the northeast looking transient in the 8/17 - 8/19 range and then back to overall above normal 8/21 and beyond.

That is just not a great look for the first potential MDR system. A wall of strong mid-to-upper shear with a sharp trough or cutoff as it moves NE of the Lesser Antilles has stayed persistent between 72 and 144 hrs over the past day or two of operational runs. May have to pay attention to the MDR setup if perhaps a second system can organize behind the first, where it could slip into better upper support or pocket of favorablility. But my enthusiasm is very much lacking so far for the first.

SPC update brings the slight risk down to the southside of DC Beltway and adds a 2% tornado risk for DC up through southeast PA/central NJ.

Seem to be losing some intensity...

I've dealth with that before, what a pain in the ass.

Low of 67. Sky has gone dark as an impressive looking line sits on the doorstep.

was splotchy

Have fun!! Hopefully storms move thru quick for you

I was basing that on his odd maps..

Nice line of storms moving across southern PA. Can hear the thunder

I could see something like that happening. Super Nino patterns tend to be warm and wet with an active storm track. It looks like he is expecting a classing appalachian runner storm track that leads to big snows for the mountains and interior regions, while the coastal areas/1-95 corridor is on the wrong side of the storm track and gets rain instead. The interior regions, elevations and northern areas have a bit more room for error with the warm anomalies than the I-95 does in terms of the precip staying frozen.

Hail too.

Sky is incredible.

Alright, enough with the rain please

First round yesterday afternoon was almost a complete miss. Everything disintegrated as it moved inland. Last night finally brought some rain. All told just over 2" between the two rounds. Something to keep the drought at bay for another week.
