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
