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.

NYC Independence Day Weekend Weather – Jun 30, 2016

NYC, Storms, Thunderstorms, Weather Update, Weekend, , , , , , , , , ,

The holiday weekend ahead will be picture perfect for nearly any type of outdoor activity, with the caveat that it will start off with some stormy weather on Friday evening/night. This batch of storms may impact travelers as they make their getaway from the city, but once they pass, the rest of the weekend will be a real gem. Any fireworks displays not scheduled for Friday night should go off without a hitch.

Rest of today – warm with a light breeze from the northwest, less humid, high in the mid-80s with sunny conditions.

Friday – mostly cloudy, high around 80ºF, increasing chance for showers and thunderstorms especially toward the afternoon and evening hours. Some of these storms could produce gusty winds. Storms continue into early overnight hours.

NYC Weekend Weather – Jun 24, 2016

Climate, Drought, NYC, Weather Update, Weekend, , , , , , , ,

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.

NYC Weekend Weather – Jun 10, 2016

NYC, Rain, Thunderstorms, Weather Update, Weekend, , , , , , , , ,

We’ve had a week of fairly mixed weather, with some days that saw thunderstorms, but a fair mix of sunny and dry conditions also. This weekend, we get another mixed bag, with a possibility of thunderstorms approaching severe limits Saturday, and a great day on Sunday. Looking ahead, high pressure begins to dominate and will ensure dry weather for the coming week.

Rest of today – we’ve hit our high in the mid-upper 70s, and we’ll continue to have sunny weather, and it’ll be a pleasant night with lows in the upper-50s to around 60ºF.

Saturday – the Storm Prediction Center has placed our area under a slight risk of severe weather for Saturday. We could see some thunderstorms rumble through in the afternoon hours as a warm front pushes in from the west, however, they will be weakening as they approach more stable air near the coast, so it’s possible these storms fizzle out before they reach the city. These storms will be moving from northeast to southeast from the interior of Upstate New York. Otherwise, expect partly sunny skies with highs in the upper-70s.

Sunday – winds pick up behind the passage of the warm front mentioned above. Temperatures also warm up into the low-80s with sunny skies.

Monday – mostly sunny with high temperatures in the upper-70s. High pressure begins to take control over our weather.

Tuesday – much the same as Monday, pleasant, mostly sunny, with high temperatures in the upper-70s.

After a couple of warm days to start the week, temperatures cool off as a cold front moves through later this evening. A second frontal boundary passes through tomorrow, ushering even cooler, and dry weather for the remainder of the week. Another chance for rain is possible Saturday as a weak Alberta clipper system impacts the area.

Rest of today – mostly sunny with a high in the low-mid 80s. There is a possibility for scattered showers and thunderstorms especially inland later this afternoon between 3-5PM as a cold front approaches from the west. Some of these storms could produce damaging wind gusts and small hail, but these are unlikely to impact the city and coastal areas where the air mass is more stable due to the influence cool ocean waters.

Wednesday – with the cold front having passed through, temperatures cool off into the low-70s. The day starts out sunny but clouds will increase ahead of another frontal boundary nears in the afternoon. Ahead of this boundary, a better chance for showers and thunderstorms develops, and once again there could be some widely scattered strong-marginally severe storms.

Thursday – temperatures will range in the 50s overnight into Thursday, leading to yet another day of below average, but comfortable temperatures in the low-70s with northwest wind driven by high pressure building to the southwest over the Mississippi Valley. This will pull in a drier, fall-like airmass from Canada.

Friday – slightly warmer with highs in the low-mid 70s, mostly sunny.

Saturday – there’s a chance for some scattered showers Saturday afternoon into the overnight hours as an Alberta clipper system approaches, otherwise, partly sunny with high temperatures in the mid-70s.

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. 610temp.new

Hope you did your taxes early because you’re not going to want to be inside this weekend. The weather will be fantastic with lots of sun and warm temperatures. This span of beautiful weather continues right through the beginning of next week. Looking ahead, it is safe to say that we are out of the grips of winter for good.

Rest of today – clear with high temperatures around normal in the low-60s.

Saturday – high pressure dominates the region with more sun, and slightly warmer temperatures in the low-mid 60s.

Sunday – warmer, with highs topping off in the upper-60s to the low-70s.

I thought we had seen the last of the snow this spring, but winter stubbornly will not give up. This week, we’ll see the coldest weather we’ve encountered since the depths of winter, with low temperatures dropping into the upper-20s in the city and even teens for outlying areas. A brief warm up occurs this Thursday before the cold returns again.

Rest of today – windy with periods of rain in the city. High temperatures will likely top off in the upper-40s to near 50ºF. Temperatures plummet into the upper-20s following the passage of the cold front that’s responsible for this round of precipitation.

Tuesday – clear skies will belie the much below normal high temperatures for the day which will be only around 40ºF. A freeze warning is in effect for most of the coastal regions in the Tri-State area given the overnight lows that will be substantially below freezing.

Screen Shot 2016-04-04 at 10.11.54 AM

Wednesday – the high pressure pictured above will be in firm control Tuesday and overnight into Wednesday. A cloudless sky overnight will make for ideal conditions for radiational cooling, resulting in low temperatures again in the mid-20s. High temperatures will be warmer in the mid-40s with increasing clouds ahead of the next storm system.

Thursday – a surge of warmer air will accompany the next storm system to impact the area Thursday. This storm system will bring widespread rain and even some thunderstorms late in the day Thursday. High temperatures should reach well into the upper-50s and near 60ºF.

Friday – following the passage of the storm on Thursday, temperatures cool off again into the upper-40s under mostly cloudy skies.
