Surface
chart and radar.
Yesterday’s
Enhanced Risk definitely verified. There were hundreds of damage reports along
with at least two tornadoes. The National Weather Service said two tornadoes
touched down in western Pennsylvania on Saturday. The first tornado: was near
Summerville in Jefferson County. The second tornado touched down just northeast
of Latrobe in Westmoreland County. Surveys will be ongoing today and tomorrow
to see the ratings of these two, and to see if additional tornadoes occurred.
Today
The cold
front responsible for all the severe weather yesterday has pushed south and
east of the region and is off the coast. Today will see clearing skies and lots
of sun. Temperatures will be seasonal with a light breeze. The best thing is
that wildfire smoke is mostly gone for now. The EPA has Pennsylvania into the Middle Atlantic Region at a moderate level. High
pressure will continue to move into the region, providing tranquil conditions
for tomorrow.
Rest of the week
A warm front
is going to approach Monday night. This will continue to move across the region
on Tuesday. Behind the front, warm and more humid air will move into the
region. Along and ahead of the front we will see rain showers and thunderstorms.
Late Tuesday
and Wednesday a series of cold fronts will move through. These are going to produce
scattered showers and thunderstorms. The conditions will allow for some of
these storms to be strong to severe. We
could have some lingering showers Thursday morning. But high pressure is going
to be moving in. The high pressure looks to stick around for a few days providing
scattered clouds and generally dry conditions.
The
Tropics
That area of
low pressure in the Northeast Gulf I was talking about last week, is now
tropical depression two. As I said it could it is tracking generally west. The
reason for this drifting back to the west; has to do with the trough over the
East Coast. The flow around this trough is coming out of the northeast and
east. Currently TD 2 has max sustained
winds of 30 mph, a central pressure of 1011 mb and is tracking north-northwest
at 2 mph.
Right now, shear is fairly low. TD2 has carved out a moist environment in the dry air that surrounds it, but some of the dry air being pulled into the circulation. This should allow for slower development for now. We do have high pressure over Texas. The clockwise flow around this high, should allow TD 2 to stay a bit offshore, over that warm water in the Gulf. But based on the overall setup, this is very likely to become Bertha. Those in Louisiana and Texas should keep an eye on this.
