As I discussed in the previous post, a large cut-off low that brought severe weather with tornadoes to our Central US is now bringing periods of rain to us.  Lifting and moisture will increase through the today as the warm front slowly approaches from the southwest. So more waves of rain, moderate to heavy at times mare expected for today. East winds gusting at times to 35mph will also keep us in very cool marine airmass. Temperatures will struggle to get out 40s. These winds will also cause some areas of minor coastal flooding during high tides this morning and early this afternoon. Especially along the shores of New Jersey and Western Long Island sound.

Tonight, a strengthening southerly low-level jet and an increasing precipitable water values will enhance moisture convergence for more widespread heavy rainfall. Elevated instability in form of MUCAPE will also be increasing for some embedded thunderstorms with torrential downpours. Rainfall totals between 2 to 4 inches are expected for most of the area. A few areas that receive more thunderstorms, could see higher totals.  This rainfall can cause flooding in the low-lying and poor drainage areas and flooding near small streams and rivers. Winds turning southeast early tonight, will cause more widespread minor coastal flooding during high tides. For these reasons, the National Weather Service have issued Flood Watches for the entire Tri-State area today and tonight. As well as Coastal Flood Advisories for areas around Western LI sound, New York Harbor for early tonight.

Any rain and thunderstorms should come to end early tomorrow morning, as the warm front lifts north of the region. Some sunshine will break out between clouds later in morning and during the afternoon with winds turning more southwest. Causing temperatures to rise into lower to middle 70s, away from immediate coast. Which will be a big difference from what we are experiencing today. Some scattered showers and thunderstorms are possible late tomorrow afternoon with passage of a weak cold front. Friday still looks drier and slightly cooler, as the entire system weakens and lifts to our north.

I will have more updates on the storm, if there any significant changes. Check the 7-day Forecast and Forecast Summary for more updates later today.
