Friday 9 a.m.
Drier air has moved into the Middle and North Atlantic states behind a frontal system that brought rain to much of the area either yesterday or last night. Boston got most of it rain from the last set of showers associated with this weather system; the city had missed the rain that hit New York City and Philadelphia earlier.
Our next concern (in terms of precipitation) is a cool front that will stretch from New Jersey and Pennsylvania to southern Illinois around midday tomorrow. There will be groups and short lines of showers and thunderstorms associated with this front, but rainfall amounts will vary widely from hardly anything to enough rain to cause temporary street flooding. Drier air is likely to promote sunshine in this area on Sunday. Downwind from the central and eastern Great Lakes, the new air mass will be cool enough to cause clouds and some showers tomorrow night and Sunday, and there can even be water spouts over the lakes. The map below shows where the frontal zone is today.

Here are two different takes on August:
August: Foot Health Month 8-2-13
August is national foot health month, but now it's time to get instep with the forecast as we go toe-ward the weekend. Every day in the summer turns forecasters into worrywarts because we don't want any storms to catch us flatfooted.
For now we are tendon toward a forecast of showers and thunderstorms tonight before drier air gains a foothold during the day tomorrow. The nights tomorrow and Sunday could cool almost to where it feels like spraintime. The flow will come out of high pressure area that will move from Mani toe ba to the Great Legs. That high will eventually bring the kind of weekend weather that just gets ingrown on you. For Sunday coast, the basic outlook is favorable weather from dock to shoal.
The weekend should be dry much of time, however, as cooler air aloft gets its foot in the door, cumulus clouds will kick up on Sunday, desenex thing you know there's a shower or thunderstorm, and you feel like a real heel if you get stepped on by rain. Some thunderstorms stride right through the area, but others hang'nail us with winds that shake buildings from the rafters to the footers before they get the boot. I usually try to be a fun guy but when there's even a sole thunderstorm on a day when I say storms will not lace the region I have to wiggle out of it. And if you're caught you try to hoof it to some door or archway until the rain stops.
So, whether you're a plantar getting ready to work in your garden, an ankler fishing for that big catch, a builder pouring foundation footings, a camper playing Paul Bunyan in the woods, a carnival worker selling tickets or taking stubs..., or an outdoor speaker standing in the footlights, the weather will be ok much of the time this weekend.
We still have more than a full month of official summer, but many of us are starting to marvel at how fast summer is passing us by. Heat and humidity are still commonplace, but we lose the sunlight in the middle of an evening walk, and pesky patches of fog sometimes linger through morning rush. The nights are filled with the symphony of crickets and lecturing locusts, but on a few of the nights we notice a breeze, the first signs of autumn's atmospheric stirrings. For many, it's back to school time soon, and even where the first day a month off, scholastic soccer and football fields become the scene of a daily struggle to make the team while the marching band goes through endless rehearsal, and rehearsal, and rehearsal. It's all leading up to fall, a colorful and festive time when cooling breezes, falling leaves, chilly dawns and hazy afternoons change our outdoor scene completely. We still have summer left: there's no weeping for the willow, bees are still the buzzwords in the garden, emerald draperies cloak the trees, ragweed rages. But as we enter August, we know our world is moving on, and the change in thoughts and anticipation of things to come add an extra sparkle on late summer days that might otherwise seem tattered and shopworn.
Yesterday, there was a sharp boundary between air that was cool and dry enough to suppress thunderstorms and air that was warm and humid enough to support them. This map shows the lightning strikes from 8 a.m. ET yesterday to (almost) the same time today.
As the second low pressure area develops off the East coast, it will work in concert with a high pressure area from Canada to orchestrate cooler-than-usual conditions with showers in the Middle and North Atlantic states Thursday.
Looking ahead to <strong>next</strong> weekend, the Mothers Day Weekend, we see quite a difference between the GFS model and European models on where cold Canadian air is heading at 2 a.m. Sunday.
Rain is spreading across the Middle Atlantic states today. Dampness will linger from southern New York state to Virginia tomorrow even as the main rain area moves offshore.
For the rest of the week and this weekend, the upper-air "steering winds" will be arranged in two separate streams. The northern branch will send air from central Canada toward New England.
In the Northeast today, the low pressure area shown on this map will move to the East Coast today, pulling the front south as a cold front. Showers and gusty thunderstorm will affect areas south of the front while steady rain and gray skies are common to the north...
