Welcome to the first day of Meteorological Fall

  

Surface Chart and Radar

 

 

 

The stalled front that was draped over New York State and Pennsylvania, is now slowly sliding back north and east.  This is going to waver back and forth over the next few days. Along the boundary waves of showers and thunderstorms will move along it. Some of these storms will be strong to severe.  This boundary is going to be separating the cooler continental air from the warmer tropical air.    

 

Today

We have a northwest flow out of the Great Lakes and Canada. The flow shows up very well on Satellite.  We’re going to see scattered showers and thunderstorms, but it won’t be a washout. Some of these storms will become severe. These storms will be capable of strong damaging winds, heavy downpours, hail, frequent lightning and there is the small chance for an isolated tornado.  The higher temperature and humidity will be very noticeable.  

 

Rest of the Week

Wednesday will be a rinse and repeat, as the boundary meanders north and south. Scattered Showers and thunderstorms can be expected. With some of the storms becoming strong to severe. Again, temperatures and humidity will be high.

 

Wednesday night into Thursday a cold front will be approaching, it will be bopping with the semi stationary front and start to push it south. Behind the front cooler and drier air will be moving in. Thursday will see the cold front slowly move through.  We can expect widespread scattered showers and thunderstorms, again some of these will be strong to severe.  As this slides south, partly to mostly sunny skies will be to the north, with cloud cover and showers to the south.  Friday will see the cold front push even farther south, with the scattered showers and thunderstorms across southern Pennsylvania, Maryland, Delaware.  Some of these storms could be strong to severe.  For Saturday and Sunday, a couple of troughs will be around, keeping the threat for isolated showers alive. But the vast amount of the weekend will be dry. Over the weekend temperatures and humidity will be cooler.  Labor Day Monday should be mostly dry, with only the threat for isolated showers. Tuesday will see a cold front approach, and slide through, bring back the threat for scattered showers and what looks like non-severe thunderstorms.

 

Tropics

Tropical Storm Edouard.

 

Edward is strengthening and currently has max sustained winds of 50 mph, with a central pressure of 1000mb. He is tracking northwest at around 8 mph.  Edouard looks like he will slowly intensify before landfall, as his center starts to get its act together. Landfall is looking to be near the border of Texas and Louisiana, This afternoon. By then he could be a strong tropical storm, time is very limited for Edward to become a hurricane. But stranger things have happened.  Edward is going to bring heavy rain for southwestern Louisiana and the Upper Texas coast extending inland across east-central Texas today, Wednesday into Thursday. General rain amounts of 3-6 inches, with locally higher amounts of 6-12 inches will be possible. Edward’s slow speed increases the risk for scattered flash flooding

 

Have a great day!
