Why is LWX forecasting in knots over land???

 

A potent shortwave trough will approach from the Great Lakes on
Friday. A strong area of low pressure will form just downstream of
this trough and track northeastward into the St. Lawrence Valley
over the course of the day. Southerly flow ahead of the system will
advect an unseasonably warm and humid airmass northward into the
area, with temperatures forecast to climb into the 80s and dewpoints
reaching into the 60s. The system`s cold front will move through the
area Friday afternoon into Friday evening. The front will move into
an environment with around 500-1000 J/kg of instability, so a line
of thunderstorms may ultimately form along the front. If
thunderstorms were to form, they may be capable of producing
damaging winds, given the strong winds that will be in place just
above the surface (around 40-45 knots at 850 hPa). Regardless of
whether storms form or not, strong northwesterly winds are expected
behind the system`s cold front late Friday through Friday night and
into early Saturday morning. Frequent gusts of 30-40 knots appear
likely across the area in northwesterly flow, and some locations may
even see some gusts above 40 knots. The Alleghenies and Blue Ridge
appear to be the most likely locations to reach Wind Advisory
criteria of 40 knots.

Starting the day out at nearly 80 degrees in Frederick County.

 

[dailylurker]

Ahhhhh... another beautiful fall morning.... wait a second. WTF! 

[kgottwald]

Getting a light rain shower in Fairfax City while only about 40% cloud cover, and a rainbow too!

[WxUSAF]

Guessing the only thing that could save DCA from latest 90 on record is a river wind most of the day? I don’t actually know what the wind direction is supposed to be…

[midatlanticweather]

I just checked on Pool hours and was very disappointed!

We haven’t closed ours yet haha

What is this shit?  PJM has declared a grid emergency due to high temps and outages.  Fall is usually when stations do their annual outages due to cooler temps.  Man, those were the days.  Now it's summer all year with 6wks of winter wedged in there.

Yep. Not liking this at all. Have been dealing with being sick since coming back from NM. And this weather is not helping.

The only thing I can see that would prevent that would be if this cloud cover building in more.

No 90s today would be a victory.

It's cloudy but clearing here, nice cool breeze as well. It's not that bad

[Mrs.J]

So after a good part of the day being cloudy there is now clearing to almost full sun. Temps had been staying in the lower 80's but are starting to rise again. Currently 84.

[mappy]

Got to 78 earlier but have had a few rain showers move thru and it’s been cloudy, 74 currently
