And come back again in moderation in, say, a fortnight. Just doesn't have that ring now does it? But it is the feelings of many in our area after this soggy and saturated September. KMDT recorded another 2/3 of an inch of liquid sunshine yesterday adding to both the monthly record total of 18.26" and the yearly record total of 61.65"! Unreal! The 14.97" previous September record was in 1975 and thanks to a similar pattern and Hurricane Eloise, flooding was prevalent then as well. Below is the track of Eloise in 75. She started as a classic African wave and tracked across the Atlantic until she unleashed her fury onto the the islands and then the US.
And here is the precip map as a result of Eloise and her remnants. Massive flooding occurred through the Appalachians and was a half billion dollar storm. Over 40 people lost their lives in the states due to her flash flooding, mostly in the Appalachians.
As for our present weather, let's start with the current water vapor image. I've placed some movements on there and I'll try to describe the current movements of the air masses involved.
Ultimately, the dry air from O Canada will win out (blue) but not until this entire upper low finally gets absorbed by the strong westerlies that are displaced to our north. The deepest moisture however has past (yellow) with yesterday's drenching thunderstorms. We could still see a shower on Thursday as another spoke of moisture will pass through midday (seen over Pittsburgh to Cleveland in above pic). But a stronger cold front will pass PA Friday as depicted by the official NWS map for Friday morning as seen below.
The large complex surface reflection of a low pressure over the Great Lakes and into Quebec will quickly accelerate NE as the jet pulls this complex finally away from our area! Friday will feature instability clouds and even a few brief showers or spritzes as a bona fide cold air mass advects SE and generates "Lake Effect" rain showers in the lee of the warm lakes. The temps a mile up will be below freezing on Saturday as shown in the map below.
Along with the much cooler temps, the dew points will be substantially lower as well. Here are the progged dew points for Friday evening. This clearly shows the surface air mass will have finally changed on brisk WNW winds! All of the deep moisture will be pushed out to sea and down to the deep south for the weekend, and quite likely until next spring!
In closing, what an unbelievable evening in MLB! The 2 greatest collapses in MLB in the final month of the season; the Red Sox blew a 9.0 game lead and the Braves blew an 8.5 game lead! And last evening, the Orioles win in a walk-off in 9....yes I said that correctly, the Orioles win! Then minutes later, Longoria from Tampa Bay strikes a low line (and I do mean low as it cleared that extremely low left field fence at the Trop) drive to culminate a 7-0 comeback to the the evil empire and walk-off into the playoffs 8-7! TB scored 6 in the 8th and 1 in the 9th to send the game into extras! Longoria capped the 8th with his 1st HR of the game, a 3 run shot to left center. As for the NL, the Phillies won an exciting extra inning game (13) mostly by some solid defensive play, and eliminated the Braves from postseason play. In doing so, the Phillies managed 102 wins this season, a team record and Charlie won his franchise record 645th win passing Gene Mauch! So now, the Phils vs Cardinals, the DBacks vs Brew-Crew, Rays vs Rangers, and the Tigers vs Yanks. Onto October, a glorious month in sports!
Enjoy your Thursday and Happy Rosh Hashanah for those who celebrate.

AA: Finally getting the rain and humidity outta here! Friday will be a transition day to a much cooler and drier weekend. Wednesday was a great night in MLB. Red Sox prove that you cannot buy a World Series championship, let alone a spot in post season!
