Warm, Humid, August Weather Contunues with the Threat of Thunderstorms!
A Big Cool Down is Coming Sunday!
There's some dense fog in the Tri-State Area again this morning, as well as spotty drizzle...
As of 3:15 a.m. the regional radar mosaic also was showing a couple of showers in the mid-
Atlantic region, most of which were occurring in eastern Pennsylvania, as well as in Maryland and
Delaware... And, as the latest front pushes from west to east across the region during the next 12
hours, these showers will pivot northeastward along the I-95 corridor... And, in addition to the
morning fog and a couple of showers, there will even be a thunderstorm in a couple of spots
today... Most temperatures will be in the mid and upper 70s, except in Philadelphia, Baltimore,
Washington, D.C. much of Delaware and South Jersey -- which will probably be in the lower 80s
before all is said and done... The Storm Prediction Center has put an area from extreme eastern
Pennsylvania through central New England in their 'general risk' category for thunderstorms,
which means they aren't expecting any thunderstorm to be strong or severe... These seems
reasonable, because there isn't much proof that the atmosphere will be all that unstable from
midday onward... The fact that all of this fog has returned early this morning is actually proof that
the environment we're in is rather stable... Rainfall totals between now and 8 p.m. will average less
than a quarter of an inch across the entire region, and then some clearing should occur later
tonight as drier air begins to filter into the area on light, westerly winds... The temperature
tomorrow should make a run at 80 degrees, and there will be lots of sunshine, which we haven't
seen too much of lately... The consensus now for Saturday (after a series of tweaks back and forth
regarding temperatures and timing) is that our next cold front, which will reaching the East Coast
later in the afternoon... This front, which will be much more potent than its predecessor today, is
going to unleash the season's coolest air mass thus far on the Northeast and the mid-Atlantic
states Saturday night and Sunday... We've settled on a forecast for Saturday of increasing clouds,
and temperatures in the lower 70s... But there should be a few widely separated showers around,
and perhaps even a thunderstorm, before the day is through...
That next cold front is going to have a wave of low pressure developing along it late Saturday and
Saturday night, which should usher a shield of steadier rain into the area either late on Saturday
night or early Sunday morning... We continue to feel very confident about the much cooler
scenario setting up for Sunday, when temperatures will fail to get out of the mid or upper 50s..
Add at least a few hours of rain to this, and you almost come up with the POLAR OPPOSITE of
what we're expecting tomorrow... So, for those who have weekend plans, Saturday should be the
better of the two days for outdoor activities -- because even if there is a shower or two, it will be
holding off until some time later in the afternoon, and temperatures will be some 10 or 15 degrees
higher than what we're anticipating on Sunday...
Have a good day!!!
