LATE WEEK EXCESSIVE HEAT

 

Much like the past few weeks, heat will come in and only remain for 2-3 days. 

Nevertheless, the hottest day of the summer season thus far for most of the region is on tap for Friday. 

SMOKE AND HUMIDITY PERSIST THROUGH THIS WEEK

 After yesterday's flooding, the region will start to dry out a bit this week; although we'll see chances for storms Tuesday and again Thursday/early Friday, much of the region will see less in the way of rain. Frontal systems will have a better push forward, moving through more briskly and giving the area more time to recover from any downpours. 

WPC Day 1-5 Total Precipitation: Less at the coast, more inland

Meanwhile, smoke from prolonged wildfires in Canada will infiltrate the Northeast states. There will be times this week where the air quality is unhealthy, particularly during the middle of the day. This combined with temps generally around 90 and high humidity will make it a challenging week for people more sensitive to poor air quality. 

Air Quality Index

After the second front goes by on Thursday, we'll get a brief break from high humidity for Friday and again Saturday. Weather systems will keep moving along, so rain chances will be low for this coming weekend. By the beginning of next week, dew points should rise to uncomfortable levels yet again; temperatures overall should average out to near normal for this time of year. 

Tropical Tidbits

Precipitation should continue to run above normal as the overall pattern from June persists with the jet stream remaining very active for this time of year (this should signal that every few days, chances for downpours should continue with high humidity values). 

RENEWED FLOOD THREAT THIS WEEKEND

After a brief break from the flood threat, the area will once again be dealing with chances for excessive rain through the weekend. The same theme applies that we've seen over the last several weeks; rainfall will be highest north and west of NYC but it could be prolific and lead to problems in areas that have seen disastrous results of late. 

Rainfall since Sunday

The stage has been set due to the rains from last weekend with already saturated ground. Humidity levels will start to once again rise to annoying levels from Thursday through the weekend. 

Along with temps near or slightly above 90, relief will be felt mainly at the south-facing shoreline. The time to watch for the most rain would be Friday and again Sunday, with Thursday and Saturday having less overall coverage of showers and storms. 

Weather Prediction Center Rainfall Forecast For Friday

 Any one storm on Friday and Sunday could produce locally very high totals just like we saw this past Sunday. The overall environment will be loaded with moisture and nearby fronts will serve as the trigger for storms to fire, especially Friday and Sunday. There will be places that see local flash floods of roads, side streets and even transit. 

Be sure to act quickly if warnings are issued for your area. 

Don't drive through water-covered roads.

FLOODING RAINS LIKLEY ON SUNDAY AFTERNOON AND NIGHT FOR NYC AND POINTS WEST

 

A band of moderate to heavy showers and thunderstorms will slowly move through the area Sunday afternoon and night. Above is where the heaviest rains should fall; there will be pockets where over 4 inches fall. Areas east of NYC will see lighter amounts of 1-2 inches. Flood watches are posted for NYC and points west for tomorrow afternoon through tomorrow night. The graphic above is from NWS; there could be places in the red areas where widespread road flooding may become a problem. 

Don't drive through water-covered roads!
