We finally get a break from the heat along with some much needed rain in the next few days. Saturday looks to be the best day of the weekend. High temperatures this weekend will range anywhere between 15-20ºF cooler than last weekend.

Overnight – lows in the mid-70s as a low pressure center passes almost directly over NYC. Because the low will be right over us, the main area of the heaviest rain will remain north of the city.

Friday – showers punctuated by periods of steady, heavier rain as bands of rain develop and wrap around the low pressure center as it tracks east. High temperatures in the low-80s with overcast skies. This low pressure system will thrive off the humid, tropical airmass in place over the region. A flash flood watch has been issued to reflect the possibility of some areas receiving 1-2″/hour rains. Embedded thunderstorms are possible, but are unlikely to reach severe limits. The bulk of the rain will fall overnight into the morning hours, and should begin tapering off in the afternoon from west to east.

Saturday – high pressure passes briefly giving us a mostly dry day with partly sunny skies with highs in the mid-80s.

Sunday – another disturbance pushes through from the south providing more chances for rain and thunderstorms. Mostly cloudy with highs in the low-80s otherwise.

Monday – skies gradually clear and temperatures warm back into the low-mid 80s.

Tuesday – warm and sunny with highs again in the mid-80s

Drought Conditions Forecast to Persist

Despite the rains this weekend, many parts of the area remain under a moderate drought, having received only about 25% of normal precipitation for this past month. The outlook for the season calls for persistence of drought conditions as below normal to normal precipitation will be insufficient to break the drought.

Recent weather headlines have been dominated by the heat. This will continue through most of the week, with relief not really in sight until Friday. There will be a chance for severe thunderstorms today, but otherwise, there will be little in the way of rain.

Rest of today – mostly sunny, hot, with highs in the mid-90s. Humidity will make it feel like the lower-100s. The Storm Prediction Center has placed parts of the region under a slight risk for severe weather today. This relates to what appear to be multiple line segments of strong to severe thunderstorms advancing ahead of a weak cold front that look to impact the area during the PM rush.

Tuesday – with the weak cold front above passing through, there will be some drop in humidity. However, temperatures are still expected to rise into the mid-90s under mostly sunny skies.

Wednesday – temperatures finally start to back off the mid-90s into the low-90s under mostly sunny skies.

Thursday – increasing clouds, high near 90ºF.

Drought Continues to Grip the Northeast

Drought continues to worsen and is now prevalent in many parts of the Northeast, with areas in Western New York and Massachusetts particularly hard hit.

This weekend’s weather can be summed up in one word: hot. In fact, if current forecasts hold, this upcoming stretch may see our first extended 90ºF+ heat wave. High temperatures don’t appear likely to drop below 90ºF until next Wednesday. During that time, the humidity will actually increase until a cold front breaks through late Tuesday. This will be another prime beach/upstate getaway weekend.

Rest of today – sunny with a high around 90ºF.

Friday – mostly sunny, slightly warmer with a high in the low-90s. There is a chance for strong to marginally severe thunderstorms late Friday with the passage of a cold front. Any relief from heat that this front and storms associated with it bring will be short-lived.

Saturday – high pressure quickly returns and temperatures continue to rise along with it. Highs are expected in the mid-90s with mostly sunny skies.

Sunday – a bit cooler, but humidity will increase as a warm front pushes through late on Sunday. High temperatures in the low-90s.

Monday – showers and thunderstorms are possible later Monday preceding a cold front that is forecast to pass on Tuesday. Highs will remain in the low-90s.

Above Average Temperatures to Stick Around

The Climate Prediction Center’s 6-10 Day and 8-14 Day temperature outlook continues to call for above normal temperatures. The heat is here to stay.

This week started off with refreshing weather Monday. Temperatures will rise slowly during the course of the week with Friday being the hottest day. The only precipitation chance appears to come on Thursday when a cold front approaches the region.

Rest of today – mostly sunny, seasonably warm, with a high in the low-mid 80s.

Wednesday – temperatures begin slowly warming up as high pressure which has been sitting right over us moves to our east. This will allow a warmer southwesterly flow of air into the region.

Thursday – warmer still, possibly with high temperatures hitting 90ºF in some spots. In general, high temperatures will reach into the upper-80s. A chance for showers and thunderstorms will build in the afternoon along with the heat and the approach of a cold front.

Friday – partly cloudy, hot with a high near 90ºF.

Drought Expands Despite Rain

With a dearth of rain continuing, some areas of the northeast (much of Eastern Massachusetts) have been placed under an area of severe drought. For us, a moderate drought persists, despite the fact that we’ve had several rounds of drenching rain over the last couple weeks.

The run of sunny, dry weather that we’ve had (with the exception of Thursday this past week) continues into the weekend. With no significant rain anticipated in the next week, drought conditions continue to worsen over the region. Next week, high pressure to the west will drive cooler than normal temperatures, with high temperatures in the low-80s.

Rest of today – sunny with a high in the low-80s.

Saturday – a copy of today, sunny with a high in the low-80s.

Sunday – slightly warmer, but sunny again with highs in the mid-80s. High pressure will be firmly in control.

Monday – mostly sunny during the day, highs again in the mid-80s, chance for showers and thunderstorms overnight into Tuesday as a cold front passes through.

Cooler than Normal Next Week, Drought Worsens

As the cold front referenced above moves through next Tuesday, it will leave a high pressure center with Canadian origins in control. This setup favors cooler temperatures, and a drier airmass. Hence, the Climate Prediction Center shows that much of the eastern half of the US will should experience below normal temperatures next week.

The continued lack of significant rainfall has led to the expansion of moderate drought which now covers much of northeastern New Jersey, southeastern New York, and all of Long Island.

We couldn’t have asked for better weather this past weekend, and Sunday in particular was a real gem for all the fathers who had outdoor plans. The run of nice weather gets a couple interruptions this week for some much needed rain, with the first half of the week heating up before a cool down mid-week.

Rest of today – mostly sunny with a high temperature in the low-80s. Today also marks the first official day of summer, which begins at 6:34PM EDT. For the first time in 70 years, the summer solstice will also coincide with a full moon.

Tuesday – a cold front pushes through overnight into Tuesday. There could be some showers/thunderstorms in the early morning hours, but these are unlikely to linger much beyond daybreak. Once the frontal boundary clears, winds pick up inland from the west, ushering in a warmer, though less humid airmass. Temperatures should rise steadily into the upper-80s to near 90ºF in a couple spots under clearing and mostly sunny skies.

Wednesday – pleasant, sunny, with high temperatures in the mid-80s.

Thursday – the next chance at rain comes with a low pressure system moving during the afternoon hours Thursday. Uncertainty remains as to the exact track of this incoming storm system. A southerly track would result in less potential for severe weather/flash flooding, and this is the scenario that forecast models seem to suggest now. Either way, it will be a cooler day with mostly cloudy skies and temperatures in the upper-70s, with a chance for showers and thunderstorms later in the day into the overnight hours.

Friday – much improved conditions with mostly sunny skies and highs in the low-80s.

Drought Worsens, Likely to Persist this Summer

The continued lack of significant rainfall this Spring has led to increasingly dry soil. The US drought monitor now has some regions of the Northeast in an area of moderate drought. The outlook for the summer suggests that the drought will persist, without much improvement.

NYC Memorial Day Weekend Weather – May 27, 2016

It’s been a week of hot, summer-like temperatures in the city, and this will continue into the Memorial Day weekend as the official kickoff of the summer season gets underway. It’s going to be an excellent weekend for hitting the beach as a pleasant, cooling sea breeze will be present. Memorial Day itself looks increasingly like a rainy day, with precipitation enhanced by an influx of tropical moisture from what could very shortly become the second named tropical storm (Bonnie) of the 2016 Atlantic Hurricane Season.

Rest of today – warm and humid with high temperatures in the upper-80s to near 90ºF. Cloud cover increases this afternoon, and scattered thunderstorms are possible along a sea breeze front, mostly confined to upper elevations in the Lower Hudson Valley.

Saturday – sunny, hot and humid again with high temperatures around 90ºF – a persistent Bermuda High will be the driver of these hot temperatures.

Sunday – another very warm day with high temperatures in the mid-upper 80s. A backdoor cold front is expected to near the area, but not push through and this frontal boundary could serve as a trigger for thunderstorms, but these will be limited to areas north of the city.

Monday (Memorial Day) – significantly cooler, mostly cloudy, with periods of rain likely as a cold front approaches slowly from the west. High temperatures in the mid-70s. Rainfall may be enhanced by tropical moisture associated with what will likely become Tropical Storm Bonnie.

Tropical Storm Bonnie

An area of showers associated with a low pressure center off the coast of Florida has been steadily becoming better organized over the last couple days. The National Hurricane Center is giving this disturbance a 90% chance of becoming Tropical Storm Bonnie. Though there won’t be a direct impact on this region, the moisture from this storm could drive heavy rain on Monday.

A Hot Summer Coming?

The Climate Prediction Center continues to call for a hot summer for almost the entirety of the United States in its latest 3 month temperature outlook.

If there ever was an ideal day to play hooky from work or school, today would be the day. As it turns out, it’s also National Bike to Work Day, and you couldn’t ask for better weather for this. This weekend will be a mixed bag though, with rain developing later on Saturday and possible Sunday. Looking ahead, a Bermuda High sets up in the next week and will push temperatures above normal.

Rest of today – picture perfect conditions, mostly sunny, high temperatures in the mid-70s.

Saturday – mostly cloudy with rain developing in the afternoon and evening hours. A low pressure system offshore to our south will be the cause of this rain, though the heaviest rain likely won’t make it onshore. High temperatures cool off into the mid-60s with cloud cover and winds moving from southeast to north as the low progresses.

Sunday – a lingering chance for rain in the morning, followed by mostly cloudy conditions, but slightly warmer with high temperatures in the upper-60s.

Monday – small chance for showers in the afternoon, high temperatures again in the upper-60s with mostly cloudy skies.

Finally Warming Up – Drought Development Likely

The development of a Bermuda high in the 6-10 day range will result in above normal temperatures for much of the Northeast, as you see from the following charts from the Climate Prediction Center. While we’re all yearning for warmer temperatures with the cool spring we’ve had, the warmth and lack of rain will be conducive for the development of drought conditions this spring. We had just recovered from a persistent, though only moderate drought this winter, but we’re way behind in terms of precipitation averages for this time of year.

What a difference a week makes in terms of the weather – we barely caught any sun last week, as we were dogged by several consecutive low pressure systems. This week, we’ve seen a shift in the jet stream and more high pressure in the picture, resulting in warmer temperatures and dry weather.

Rest of today – partly sunny with a small chance for showers later in the day and high temperatures in the mid-60s.

Wednesday – sunny, with high pressure in control, warm with temperatures in the low-mid 70s.

Thursday – another nice, sunny day, with high temperatures a shade cooler, in the low-70s.

Friday – the next chance for substantial precipitation comes along with a cold front arriving later in the day. Cloudy, with temperatures cooler in the mid-upper 60s.

Sunny but still below average

Temperatures will be much warmer than last week, but we’re still going to be missing the mark for average (around 70ºF) for the next few days.

NYC Weekend Weather – Mother’s Day – May 6, 2016

It has been a long week of cool, wet, and dreary weather, but the end is in sight. A series of pesky waves of low pressure and storms have been impacting the region. The last of these, a persistent cutoff low that has spun off a few bands of moderate to heavy rain earlier today, will slowly weaken get absorbed into an incoming frontal boundary. This should result in a decent Mother’s Day.

Rest of today – cool, cloudy, with a high in the low-mid 50s. Another round of round of rain looks to impact the region around 7PM this evening.

Saturday – mostly cloudy, though there is a possibility of breaks in the clouds. Slight chance of some occasional showers, but nothing as heavy as today. High temperatures in the low-mid 60s.

Sunday (Mother’s Day) – starts off cloudy with a lingering chance for showers, but skies should clear fairly quickly later in the day, which should result in high temperatures in the mid-60s.

Monday – the first mostly sunny day we’ll have seen in over a week, with high temperatures in the mid-upper 60s.
