A big ridge that began to take over around mid-week last week continues to dominate the east with heat streaming in from the SW , today the heat will reach its peak before a cold front moves through and the ridge of high pressure gets the boot out to sea along with the heat
You can clearly see the heat along the east coast coming from the SW but there’s currently a cold front over the Midwest which will swing east through the area tonight
Today there will be a deep SW wind ahead of the cold front with temperatures sky rocketing into the upper 80s to mid 90s for most of the area besides Long Island where the SW flow will lead to more of an ocean influence so highs in the mid 70s on the southern shore to low 80s on the northern shore. Philadelphia and DC can expect the highest readings where low to mid 90s are expected while the NYC metro should sit between 86-90 and it will be VERY HUMID with dew points in the low to mid 70s, so real feels today are expected to be in the mid to upper 90s!!
Later tonight that line of showers and storms to our west will begin to swing through the area, the timing is not good for severe weather, so the severe threat should remain west of us where the storms will hit during the day and hit while to most dynamics are in place, for our area, this line will bring showers and some gusty thunderstorms which could be rather strong, but expect mainly just ordinary storms but very heavy downpours can be expected and some local flooding will be possible, heavy rain is the main threat.
Here is late tonight into early tomorrow AM and you can see the line is moving through the area with locally heavy rainfall and showers with imbedded thunderstorms
Tomorrow morning will feature left over showers and storms followed by clearing skies, and a wind shift from SW to NW which will lead to rapidly decreasing humidity, it will still be rather warm tomorrow with downsloping winds off the Appalachians with highs in the low to mid 80s but much drier humidity wise, then a polar air mass will work down tomorrow night into Thursday leading to much cooler conditions
Thursday and Friday highs will range from the upper 60s interior to low to mid 70s elsewhere with a NW wind and clear skies and lows will range from the mid 40s interior NE PA to upper 40s to low 50s elsewhere, warmest along the coast
It looks like a potentially significant storm system will impact us late week into the Weekend
A deep trough will dig into the midwest and a strong area of low pressure will form along the base, it then looks like the trough will turn negatively tilted so a SE wind wll transport moisture from the Atlantic leading to potential for heavy rainfall and a significant rainfall is posible Saturday into Sunday
