Near Term

Last Updated: 9:30am Thursday, July 26th 2019 by MP

Near Term (through tonight)

High pressure will provide mostly sunny skies today. 850mb temperatures around 12-13 C with deep mixing and light northwest downslope winds will support high temperatures closer to normal-in the middle 80s throughout much of the region. Humidity will still be relatively low, which will make for another beautiful mid-summer day.

Tonight, will remain mostly clear with light winds. This will result in more radiation cooling. Low temperatures are likely to in the mid 60s many of suburbs and in upper 60s to near 70 degrees in NYC and urban areas. Some of the far northern Interior valleys will likely drop into the upper 50s to lower 60s.

Short/Long Term

Last Updated: 9:30am Thursday, July 25th, 2019 by MP

Short/Long term (Friday through Wednesday)

A warming trend and increasing humidity is expected as move into Friday and the weekend, as upper-level ridging builds and a return southwest flow develops around high pressure off Mid-Atlantic coast. Temperatures will trend above normal again with highs in the mid-upper 80s or lower 90s each day. Sea-breezes will keep shore areas a little cooler. A few weak passing mid-level shortwaves, thermal troughs with increasing instability could help trigger few isolated showers or t-storms over the Interior. But mainly tranquil weather is expected through the weekend.

A couple stronger disturbances moving along the northern periphery of the ridge, may increase convection chances during the early or middle of part next week. But very warm and humid conditions will likely remain with temperatures in upper 80s or lower 90s again.

Extended Term (8-14+ Days)

Last Updated: 10:00am Thursday, July 25th, 2019 by MP

Extended Term (early August)

The pattern for the first couple of weeks of August will likely dominated by the Western Atlantic ridge with more surges of warmth and humidity for the Northeast US. This is supported by the lower AAM/MJO forcing progression through the Indian Ocean. Whether or not a more significant heat wave develops will depend on how much the EPO/NAO allows for the ridge to expand. A weakness in the ridge closer to the East Coast, may also support an active pattern with more convective threats.

In fact, the latest GEFS and EPS guidance indicates strong anomalous blocking ridge causing a heatwave in Europe will retrgrode back into Artic/NAO regions. This may result a period lower heights and somewhat cooler temperatures over the Northeast US, before the Western Atlantic ridge can flex back again.

Good evening! Light snow moved across much of the New York City metro area early this morning with 1-3″ being reported over the majority of the area. Active times look to continue as we’re tracking not one, but two more systems that have the potential to deliver some impactful snow to the region!

Good evening! The area of light snow that we have been monitoring for the past couple of days continues to move well to the north of the NYC area this evening. A couple more snow threats will approach the area over the next few days as below normal temperatures take over for the beginning of […]

Snow likely in New England on Wednesday

February 26, 2019/0 Comments/by John Homenuk

Cold air has returned to the Northeast today, with still-blustery-but-not-end-of-times-blustery winds and very cold temperatures this morning. The good news? It’s clear and calm, and high pressure over the Eastern United States will continue to keep things that way through the remainder of the day. This will begin to substantially weaken the pressure gradient over […]
