Good morning everyone. Parts of the Northeast are still enjoying some nice weather, but clouds have begun to invade the lower quadrant. That is thanks to our tropical system that came ashore in the Carolinas yesterday, bringing with it some embedded severe weather, heavy rain, and gusty winds.

We won't see that here in Pennsylvania, New Jersey, or New York, but we could see some scattered gusty showers tomorrow and Thursday before things slowly clear out Friday. What's more important is that we have some fall air just in time for the arrival of fall itself. Look for temps to cool off into the low 70's by Saturday, then 65-70 for Sunday and the start of your work week with some relatively crisp nights.

That tropical system which hit North Carolina & South Carolina yesterday, is bringing much needed rain to eastern Tennessee, Kentucky, and interior parts of Virginia. We also continue to see some heavier showers & storms along the North Carolina and Virginia coast. Those will be capable of locally strong winds, torrential rain, and frequent lightning.

The same tropical energy reaches all the way down into the Florida Keys, where we are seeing some widespread heavy showers and thunderstorms across extreme southwest Florida as well. These storms will be capable of frequent lightning, locally damaging winds, torrential rain, and the risk for a few waterspouts.

The primary focus of today's forecast though belongs to the Midwest and eastern Rocky Mountain states. Strong low pressure and a trailing cold front, will exit the Rockies stretching from North Dakota and South Dakota, down into Nebraska, Kansas, and Texas. This will set the stage for a possible severe weather outbreak from north to south along the boundary of much cooler air, and a warm/humid air mass.

By later this afternoon and into the evening hours, we should see a long, broken line of strong to severe storms in parts of South Dakota, Wyoming, Colorado, Nebraska, Kansas, Oklahoma, and north Texas. These storms will be vigorous in nature, capable of 70mph winds, very large hail, frequent lightning, torrential rain, and the risk of a few strong tornadoes. Action should begin to settle down in the late overnight hours before sunrise tomorrow.

Here is your local NYC Metro forecast -

Clouds are here to stay today, but we should remain dry until overnight tonight or tomorrow morning. Highs today will be in the mid to upper 70's and a steady fetch off of the ocean.

Look for scattered gusty showers tomorrow and Thursday and highs in the mid 70's for a cool feel. Clouds slowly decrease on Friday, with a mix of sun and clouds by afternoon. Highs again in the mid 70's.

Cooler air begins to creep in on Saturday with a mix of sun & clouds and low 70's, then more sunshine on Sunday with 65-70 degree temps for good football weather.
