The surface chart and satellite show high pressure is in control all the way from the Northeast into the Midwest. Radar is showing virtually nothing is going on overhead. Temperatures are running slightly below average along with low humidity. It's the perfect day.
We have a cold front to our south. The satellite shows tropical moisture sitting over the Southeast between two upper-level features and that cold front. The cold front is going to come back north as a warm front starting tonight into tomorrow. As the warm front lifts northward Maryland and Delaware will see increasing clouds and start to feel the higher humidity along with a few showers tonight. This will continue to move north during the overnight and through tomorrow. For most of us the scattered showers and thunderstorms will be around for the afternoon into the evening, not everyone will see them, but they will be around. The front will reach northern New York State and northern New England tomorrow evening. So, by Thursday the entire region will be hot hazy and humid.
For the
second half of this week through the weekend, temperatures and dewpoints are
going to continue to increase, making it feel very much like the Dog Days of
Summer (hottest, most sweltering days of Summer) hanging around. Each day will
feature scattered showers and storms as a weakening cold front move across the
region.
During the
next several days, the threat for widespread severe storms is very low, but
there is a chance for isolated storms to become strong to severe. These pop-up
severe storms are typical for the summer. With the humidity heavy downpours
will be the biggest threat, but gusty winds and small hail could also occur. Monday will be the last day of the higher heat
and humidity, as a stronger cold front will be approaching and moving through
on Tuesday into Wednesday. With the front will come the greater risk for
widespread strong to severe storms.
Have a day!
