NYC Weather Update – May 8, 2017

NYC, Weather Update, , , , ,

Weather conditions calm this week after a wet and unsettled weekend. Temperatures continue to trend below normal for this time of the year. Most of the week looks like it will be dry, with the next chance for rain coming over the weekend.

Rest of today – sunny, with a high near 60°F.

Tuesday – sun and clouds, a high again near 60°F.

Wednesday – slightly warmer with high temperatures possibly moving into the low-60s with more sun anticipated. High pressure should hold up enough to prevent any rain associated with a basically stationary low pressure system to our northeast.

Thursday – high temperatures in the low-60s, increasing clouds.

NYC Weekend Weather – May 4, 2017

This weekend brings a drastic change in temperature from the last, with high temperatures fully 20°F cooler. Not only that, but a slow moving upper low pressure system will induce multiple rounds of rain resulting in an extended period of unsettled weather for the area. The most substantial rain occurs Friday. Temperatures remain 5-8°F below normal during this stretch which continues into next week.

Rest of today – enjoy the bright sun shine while it lasts. With high pressure still in control, expect mostly sunny skies and a high temperature in the low-60s.

Friday – the same storm system that has been impacting the mid-Mississippi Valley with flooding rains starts to move into our region Friday. Steady rains and embedded thunderstorms throughout the day could bring a total of 1-2″ of rainfall totals. The band of heaviest rains appears likely to cross into the city around 11AM. Temperatures will be about the same as today, in the low-60s, under mostly cloudy skies.

Saturday – unfortunately, due to the slow moving nature of the low pressure system responsible for the rain Friday, there remains a lingering chance for rain Saturday, particular late in the day and into the evening. Temperatures remain cool in the low-60s.

Sunday – improving conditions, with rain chances finally diminishing. There could be some breaks for sun, with high temperatures hovering at just about 60°F.

 

Drought Almost Totally Gone, Cooler Temperatures Prevail

With all of the plentiful spring rains, only a very small slice of the Hudson Valley remains under abnormally dry conditions. Meanwhile, Climate Prediction Center points to cooler conditions continuing into the next 6-10 days.

 

 

NYC Weather Update – Apr 24, 2017

NYC, Rain, Storms, Weather Update, , , , , , , ,

Today through mid-week, we will see mostly cloudy weather, along with soaking rains Tuesday which will also feature temperatures much below normal. Later in the week and into the weekend, we will see a warm up into summer-like weather that should last into the weekend as well. A Bermuda high sets up, a pattern more typical of late June. I will be in Cuba until May 2nd so this will be my last update for the next week at a minimum.

Rest of today – cloudy, high temperatures in the low-60s. Rain developing late and into the overnight Tuesday.

Tuesday – soaking and steady rainfall accompanying a slow moving coastal storm looks set to impact the area for the entirety of Tuesday. Along with this rain, a raw east to northeast wind will make the high temperatures in the low-50s feel even chillier.

Wednesday – showers may linger as Tuesday’s storm slowly pulls away to the east. Temperatures rebound nicely into the mid-60s, could go a touch warmer if clouds break up a bit.

Thursday – a warming trend begins on Thursday with temperatures climbing into the low-70s and mostly sunny skies.

NYC Weekend Weather – Apr 21, 2017

A cool and dreary end of the week leads into a continued stretch of slightly below average temperatures for the weekend. Temperatures remain on the cool side with chances for rain to start next week before a warm up in the second half of next week. Far off in the Central Atlantic, a rare April tropical storm (Arlene) has formed.

Rest of today – rains moved through overnight and lingering showers this morning should end within the next couple hours. Cloudy with high temperatures only in the upper-50s to around 60°F.

Saturday – despite winds turning to the north with high pressure moving in from the west, temperatures should still rebound into the low-60s. Partly to mostly cloudy skies.

Sunday – mostly cloudy to overcast with temperatures hovering around 60°F.

Monday – the next chance for rain comes in along with a developing coastal low that lingers through Tuesday. Timing of this coastal storm remains somewhat uncertain, so it could end up being somewhat of a pest early next week.

 

Rare April Tropical Storm
We’re still 2 full months off from the official start of the 2017 Atlantic hurricane season, which makes the formation of the first named storm of the season even more of a meteorological oddity. Tropical Storm Arlene will spend its life churning up the waters of the Central Atlantic without any impacts on land. It’s still worth noting that this is only the second time since the dawn of the satellite era that a tropical storm has been detected in April.

TS Arlene is the tight circulation located at around 50° W, 40° N

NYC Weather Update – Apr 17, 2017

The incredible run of summer-like weather we’ve enjoyed the last week comes to a close as a more seasonable weather pattern takes hold this week. Temperatures will range from average to slightly below average and we’ll see a chance for rain late this week.

Tuesday – mostly clear skies with high temperatures in the upper-50s, possibly reaching into the low-60s. An easterly onshore breeze induced by a high pressure center to the northeast will bring cooler these cooler temperatures.

Wednesday – cooler day on tap with increasing clouds and high temperatures in the low-50s.

Thursday – chances for showers as a warm front then cold front push through from Thursday into Friday. High temperatures a bit warmer in the low-60s before the cold front passes.

Friday – chance of rain diminishing through the day with mostly cloudy skies and temperatures again in the low-60s.

 

Drought Over, Cooler, Wet Pattern in Store

With bountiful spring rains recently and that late winter snow storm, we’ve fully recovered from drought conditions across almost the entirety of the state with the exception of parts of the Hudson Valley and Catskills.

Multiple rounds of storms are expected to favor a cooler and wetter medium term outlook.

NYC Weekend Weather – Mar 31, 2017

Climate, NYC, Rain, Weather Update, Weekend, , , , , ,

March ends on rainy note. It’s been a cooler and wetter month than average, after a much warmer February. The snow and rain has made significant positive impacts on the drought in this region. We get one good day this weekend, before more rain moves in to start the first week of April.

Rest of today – overcast, periods of rain, heavy at times due to a slow moving low pressure center. The heavier rains look to come later this evening into the overnight hours. Easterly and northeasterly winds will make it feel cooler than the high of around 40ºF.

Saturday – due to the slow pace of this storm, rain is still likely to be falling early tomorrow. High temperatures will remain well below normal due to the continued onshore easterly winds and cloud cover, only reaching the mid-40s.

Sunday – with the low pressure center finally exiting east, we should see dramatically improved conditions with highs rebounding to normal levels in the mid-50s and lots of sunshine.

Monday – starts off similar to Sunday with mostly sunny skies and temperatures in the mid-50s. Conditions deteriorate later in the day as the next storm system starts moving in.

 

Average Temperatures, Above Average Precipitation to Start April

Due to the influence of several storm systems forecast to impact the area, we’re expecting normal temperatures and above average precipitation to start the month off.

NYC Weather Update – Mar 27, 2017

Climate, Drought, NYC, Rain, Weather Update, , , , , ,

Active weather pattern to start the week brings us multiple chances for rain. Things settle down mid-week, but another chance for rain comes up late week and into the weekend. Beneficial rains and the snow from the last Nor’easter has put a significant dent in drought conditions area wide. It looks like we’ve turned the corner legitimately towards spring with average to above-average temperatures expected for the foreseeable future.

Rest of today – rain tapering off by the early afternoon. Some clearing possible later. High temperatures in the mid-upper 50s.

Tuesday – mild, high temperatures around 60°F, slight chance for rain lingers throughout the day with a cold front approaching from the west.

Wednesday – rain is likely overnight Tuesday into Wednesday as this cold front moves through. On Wendesday itself, after the cold front pushes through, gradual improvement in weather conditions is expected with clouds breaking and a high in the mid-upper 50s.

Thursday – best day out of the week with high temperatures right around average in the low-50s and plenty of sunshine.

 

Temperature, Precipitation Trends and Drought Update

Over the course of the next week to week and a half, we’re expected to see average to slightly above average temperatures along with slightly above average rainfall. This bodes well for the overall drought situation which has seen marked improvement since the region received significant snowfall from the last Nor’easter and winter storm.

NYC Blizzard Update #2 – Mar 13, 2017

Freezing Rain, Noreaster, NYC, Precipitation Type, Rain, Snow, Storms, Weather Update, , , , , , , , , , , , , , ,

The track of the imminent nor’easter and blizzard has continue to trend west of earlier model runs. This has introduced increasing uncertainty as to overall snowfall totals along the immediate coastal areas along with possible wintry mix/freezing rain. On the other hand, confidence is increasing in heavy snow for areas north and west of the city, with snowfall totals 18″+ looking likely.

Impacts – heavy snow north and west of the city, snowfall accumulations in the interior 16-20″+ looking likely. Sharp gradient in the heaviest snowfall totals approaching the coast where wintry mix, freezing rain, and even plain rain could mix in during the early afternoon Tuesday. The exact location of the extent of warm air intrusion off the ocean will ultimately determine the difference between routine totals over 1 foot and areas that receive much lower snowfall totals. The difference in some cases could be a matter of mere miles. This line could fall in and around NYC itself. Still expecting a period of blizzard or near blizzard conditions for NYC during the course of this storm even if a transition to mixed precipitation does occur. Snowfall totals could still pile up close to a foot or over prior to this transition. The possibility of freezing rain and ice introduces an additional hazard on the roads and when coupled with strong winds of 30-35mph and gusts 45mph+ could result in power outages.

Timing – light snow should begin to fall early into the overnight hours, progressively growing in intensity. In the city, overnight accumulations of 3-6″ possible, with a sharp increase in totals north and west. Heavy snow with sleet and wintry mix during the morning and early afternoon in the city, all snow in points north and west. Blowing and drifting snow with blizzard conditions possible. Snow begins to wind down during the evening hours.

Caveats – any further movement of the storm track west would result in drastically lower snowfall totals for NYC and points east along the coast. Correspondingly, an eastward shift of the storm track would put NYC itself squarely in the bullseye for the heaviest snows.

NYC Weekend Weather – Mar 09, 2017

Above average temperatures today give way to accumulating snow Friday. Very cold air then rushes in for the weekend, much along the lines of last weekend. This time around, cold air will persist, as a polar vortex is set to take hold of the East Coast. With this cold air in place, there is potential for a significant snowstorm in the form of a Nor’easter/coastal storm early to mid-week next week.

Rest of today – quite warm still with high temperatures remaining steady around the mid-50s. Breezy with west wind between 15-20mph under clear skies. Increasing clouds towards nightfall.

Friday – a rain/snow mix is anticipated to begin falling overnight, steadily transitioning to all snow by daybreak. This looks to be a messy commute. A cold front slides south of the area and a strengthening low pressure center moves along this frontal boundary, bringing us this snow. Due to warm temperatures in preceding days, snow will have a hard time sticking at first, but temperatures will remain cold enough throughout this event to yield likely snow accumulations of 3-5″.

Saturday – temperatures will remain well below normal as winds shift to the northwest following the passage of the cold front and storm system above. Breezy with winds around 15-20mph and decreasing clouds. High temperatures will struggle to hit freezing. Overnight lows leading into Saturday and then overnight into Sunday only in the teens.

Sunday – cold, sunny, with high temperature again barely at or above freezing. Spring forward occurs early Sunday, set your clocks ahead and get ready for more sunshine late in the day (not that it’ll help make things warmer right now).

 

Winter Not Giving Up – Possible Snowstorm Next Week

The predominant weather pattern thus far this winter has been one in which the jet stream has taken on an orientation that favors above average warmth over the eastern half of the US. Just as we turn the corner towards spring, it appears we are about to get slammed with a polar vortex and weather pattern more typical of February. While the cold itself will be enough to put a damper on spring, the real headline is the possibility for a significant late-season snowstorm in the form of a Nor’easter some time early to mid-week next week. Will keep you all updated on this as more data becomes available in the coming days.

NYC Weekend Weather – Mar 3, 2017

NYC, Snow, Weather Update, Weekend, , , , , , , ,

The record breaking warmth of only a couple days ago seems like ancient history. We could see some snow flurries to kick off the weekend, then a very cold airmass takes hold with temperatures well below normal. Another warm up is in store to start next week.

Rest of today – mostly sunny to clear skies to start. High temperatures near 40°F. Later in the day, and into the evening hours, an arctic front is forecast to pass through. Snow showers are anticipated to accompany this frontal boundary, though they should not result in any appreciable accumulation.

Saturday – behind the passage of this arctic front, winds shift to the northwest and pick up into the 15-25mph range, with stronger gusts. High temperatures will struggle to top freezing even with lots of sun, as overnight lows will be around 20°F. Wind chills will be in the teens or lower.

Sunday – overnight into Sunday, low temperatures are expected to drop into the teens. Sunny conditions prevail, with slightly warmer temperatures in the mid-30s.

Monday – a warm front will push through, finally breaking the spell of very cold weather. Temperatures should warm up into the upper-40s to near 50°F as clouds increase.
