Severe Weather Risks Again Today Northeast Mid Atlantic,

Hurricane Lee Category 5 Hurricane

Thursday evening saw some vicious thunderstorms move across Eastern Pennsylvaniia and parts of Upstate NY and Northwest New Jersey. We have a similar set up for today as a cold front is stalled to the west along with an upper trough that is hanging southward along and just west of the Appalachians. This is going to set us up for another round of severe thunderstorm potential later today and into tonight. The Storm Prediction Center has a large geographic area of slight risk from Norhteast Virginia all the way up into Western Maine.

Ahead of any thunderstorms that develop later today, it will be another miserably very warm to hot and very humid day across Eastern Pennsylvania to Southern New England with air that barely moves. Sunshine will boost temperatures to the upper 80s and lower 90s which at least is a little lower than the last couple of days. Then late this afternoon and this evening expect another line of very strong thunderstorms to develop in Eastern Pennsylvania and they will move east into New Jersey and the Hudson Valley though they should weaken by the time they reach the Southern New England and Long Island coast.

This cold front has no plans to pass through anytime soon though it does nudge a bit further to the east today and tonight and then sits stalled overhead for Saturday and Sunday. Another warm humid night lies head with will most lows in the unreasonable 70s. Then both Saturday and Sunday will feature clouds with some breaks of sun in the mix. Temperatures will be a little lower both days with highs in the low to mid 80s Saturday.

There will be some scattered thunderstorms running around later Saturday into Saturday night but severe weather risks may be a bit less. Dew points will be very high and into the 70s on both weekend days. Sunday look for clouds and some breaks of sun but with the front overhead highs will be in the upper 70s and lower 80s. There is also the chance for some thunderstorms in the afternoon and evening.

Next week brings more chances for showers and thunderstorms on each day as we deal with dying weather fronts and new frontal systems that will try and approach and move through. Meanwhile in the tropics we have Category 5 Hurricane Lee which strengthened rapidly yesterday. Maximum sustained winds are 160 mph and the west northwest course continues into early next week.

At the very least, Hurricane Lee will begin to produce high seas, very rough surf, rip tides, and higher than normal tides up and down the Eastern Seaboard beginning later Sunday and those conditions are forecast to last all week long. We can also say that it appears that the from the Southern Mid Atlantic to Florida, the risk of any landfall is near zero. Lee is eventually forecast to turn to the north early next week but when and exactly where in the Atlantic is still up for grabs. A turn northward near 70 degrees west seems plausible and then an accelerating northward motion from there. Models are still in a place where they keep shifting the upper air patterns around in the Eastern US for later next week. Right now there is the chance we could see a close pass to Eastern New England and Atlantic Canada (Nova Scotia and Newfoundland) late next week. Much will depend on how far west Lee gets before it makes the turn. As strong as Hurricane Lee is, we could see further strengthening today before eye wall replacement cycles begin and then the strength of Lee will fluctuate. It is forecast to remain a strong category 4 or category 5 hurricane through the weekend.
