NYC Weekend Weather – Mar 2, 2018

Flooding, NYC, Rain, Snow, Storms, Weather Update, Weekend, , , , , , , , , , ,

March arrives as a roaring lion this year with a powerful nor’easter impacting the region during the first half of the weekend. A variety of hazards from snow to high winds to coastal flooding will affect the area before this nor’easter meanders its way out to the open ocean. Behind this storm, the large scale pattern shifts and much cooler air rushes in, displacing unseasonable warmth with more average temperatures for the week to come.

Rest of today – rain and snow mixing. Little to no accumulation expected. Winds increasing from north to northeast winds 20-25 mph to 30-35 mph with gusts as high as 60 mph near the coast possible later today. Moderate coastal flooding possible over multiple tide cycles tonight, and Saturday. These tides will be higher than normal since they are falling on the full moon (spring tides). Temperatures will hold steady in the upper-30s.

Overnight, an inland low and coastal low consolidated offshore of the Northeast and the coastal low has already rapidly strengthened to a minimum pressure of 984 mb this morning. Two branches of the polar jet have phased together, providing the energy for this robust storm. As the storm continues to deepen, the pressure gradient between it and an area of high pressure over the Upper Midwest will continue to increase, leading to stronger winds. Onshore flow of these winds from the north and northeast over an extended period of time are expected to bring coastal flooding. Periods of moderate to heavy rain could lead to flooding in general. Although the cold, northwest flank of the storm as it exits to the east will support snow (with its cold conveyor belt), accumulations at the coast should be limited. This is another story inland where heavy snow is expected in the Lower Hudson Valley.

Saturday – periods of moderate to heavy rain with snow mixing in continue overnight, but should taper off by the morning. Winds will diminish from the 30 mph range with gusts up to 55 mph overnight but will remain stiff in the 20-25 mph range from the north. Much colder feel with highs in the mid-40s under partly sunny skies.

Sunday – much nicer day, winds finally abating with high temperatures in the mid-40s and mostly sunny skies.

Monday – sunny, with high temperatures in the mid-40s.

NYC Weather Update – Feb 26, 2018

NYC, Weather Update, , , ,

A wet and windy Sunday gives way to a week of mild and drier conditions. Temperatures this week will range about 10F above normal. While not remotely close to the record-breaking highs set last week, this should still result in pleasant conditions. Dry weather should hold up until late in the week when our next chance for rain arrives.

Rest of today – decreasing clouds with high temperatures in the mid-50s.

Tuesday – sunny, high temperatures again in the mid-50s after a colder start to they day.

Wednesday – mostly sunny with high temperatures in the mid-50s as an area of high pressure continues to dictate sensible weather in the area.

Thursday – as this high pressure moves off to the east, increasing clouds will build ahead of the next storm system. Chances for rain will increase through the day with cooler temperatures in the upper-40s.

 

NYC Weekend Weather – Feb 23, 2018

A wet and unsettled weekend is coming up for NYC after a week that saw record-breaking warmth and large temperature swings. Back-to-back mid-latitude cyclones with their attendant warm and cold fronts will move through the area bringing a cloudy, gloomy feel, and plenty of chances for rain.

Rest of today – multiple rounds of rain showers possible through the morning and afternoon hours ahead of a warm front advancing from the southwest. Rain chances diminishing after around 6PM this evening. Overcast otherwise with a high temperature in the low-40s.

Saturday – overnight temperatures warming due to warm advection ahead of that warm front. We’ll end up in the warm sector of the first of these two mid-latitude cyclones on Saturday with high temperatures rising into the mid-upper 50s under mostly cloudy skies. Some chance for a scattered shower more likely later in the day as some post-frontal rain develops with a cold front exiting to the east.

Sunday – slightly cooler, high temperatures in the upper-40s. Another cloudy day, with rain continuing from overnight Saturday as first a warm front then a cold front moves through with this second storm system.

Monday – finally a dry day with mostly sunny skies and high temperatures in the mid-50s after this chain of storms!

NYC Weather Update – Feb 12, 2018

After a soaking rain this weekend, we start the week off with cooler, drier conditions. Temperatures ramp up going into mid-week before the next chance for precipitation hits us Thursday.

Rest of today – decreasing clouds as high pressure builds behind the cold front that passed through earlier today. High temperatures in the low-40s dropping through the course of the day.

Tuesday – mostly sunny with high temperatures in the mid-30s.

Wednesday – milder with high temperatures in the upper-40s and increasing clouds late in the day.

Thursday – a surge of warm air ahead of the next cold front to hit the area will raise temperatures well into the 50s, possibly as high as 60°F but with a chance for showers and mostly cloudy skies.

NYC Weekend Weather – Feb 9, 2017

Cold start to this weekend gives way to a milder feel but a soaker of a day Sunday. Going into next week, much of the week will see above average temperatures.

Rest of today – increasing low-level clouds associated with warm air advecting from the south ahead of a warm front. Temperatures still on the cool side during the day with high temperatures in the mid-30s.

Saturday – overnight temperatures actually start to rise as warm advection really takes hold. High temperatures will substantially warmer near 50°F. Cloudy with increasing chances for rain as a cold front approaches from the west.

Sunday – the cold front above will stall in our vicinity, with tropical moisture surging along this frontal boundary. This will result in multiple rounds of moderate to heavy rain. Temperatures will be in the low-50s.

Monday – cooler but still decent with decreasing clouds and high temperatures in the mid-40s.

The groundhogs have spoken. Our own Staten Island Chuck predicts an early spring, while his more famous counterpart Punxsutawney Phil predicts 6 more weeks of winter. Well, it certainly won’t feel like spring this coming weekend as we endure chilly conditions today and tomorrow before a slight warm up with a chance for precipitation Sunday.

Rest of today – clear, but windy with a northwest breeze 20-25 mph range. This will quickly sweep in much colder Arctic air via cold advection, and as a result temperatures will drop through the day from a high around 30°F.

Saturday – with overnight lows dropping into the teens, Saturday will likewise be a cold day with high temperatures only reaching around 30°F. Clouds will increase as the warm front associated with the next area of low pressure to hit the area moves in late in the day.

Sunday – with the warm front passing over us, winds turn to the southwest and warm advection will result in temperatures warming overnight into Sunday when high temperatures are expected to reach the low-40s. Precipitation in association with the cold front attached to the low pressure below will likely begin as all snow in the city before transitioning to a rain/snow mix or all rain with temperatures rising well above freezing. Little to no snow accumulation is expected – but the journey to and back from various Super Bowl related festivities will be messy.

Monday – things dry out and conditions improve as temperatures top out in the upper-30s with partly cloudy skies.

 

Chuck’s Wrong, Phil’s Right

Unfortunately for those of you who like warmer weather, Staten Island Chuck’s prediction of an early spring is likely to be off the mark. A progressive series of storm systems and an oscillating jet stream will bring multiple bouts of cold weather to the area before the winter’s out. Climate Prediction Center has our region in an area of 33% chance for below normal temperatures in their monthly outlook.

This week starts and ends with some active weather. Colder temperatures that swept in after the passage of a cold front this weekend will be here to stay for the remainder of the week. We get a couple chances to see some snow, but not anything of considerable quantity.

Rest of today – partly sunny with high temperatures in the low-40s. A coastal storm passes by but far enough offshore that we shouldn’t see serious impacts from it.

Tuesday – chance of rain and snow in the overnight hours with some troughs rotating around the back side of this departing coastal low. Could have enough snow to make for a messy morning commute, but we’re not looking at any significant accumulation. Cloudy otherwise with temperatures topping out in the low-30s.

Wednesday – mostly sunny with high temperatures around freezing.

Thursday – increasing clouds with temperatures warming into the mid-40s in the warm sector before the next storm system hits us.

NYC Weekend Weather – Jan 26, 2018

We follow the general pattern of last weekend with a warm up occurring, accompanied by some rain on Sunday. Temperatures cool off again to begin next week. Snow is possible late Monday into early Tuesday.

Rest of today – mostly sunny with highs in the mid-30s. A warm front pushes through and winds shift to the southwest, setting the stage for much warmer temperatures over the weekend.

Saturday – a gem of a day with high temperatures in and around 50°F and sunny skies.

Sunday – showers as a cold front pushes through. Temperatures still warm in and around 50°F. Mostly cloudy otherwise. 

Monday – temperatures cool back off into the low-40s after the passage of the cold front bringing rain on Sunday.

NYC Weekend Weather – Jan 19, 2018

The relatively minor cold spell we’ve had this week transitions into a dramatic warm up going into the weekend. Above normal temperatures will persist into the beginning of next week before moderating later in the week. We have a chance for a soaking rain beginning Monday night going into Tuesday.

Rest of today – partly sunny with some gradual clearing later. High temperatures in the upper-30s to around 40ºF.

Saturday – much warmer due to a dramatic shift in the jet stream with high temperatures around 50ºF with warm air rushing in from the south and west ahead of a frontal boundary. The polar jet that’s brought a return of cold air to the region will be pushed considerably further north of us with high pressure building to the southwest. This is a setup favoring much warmer air flowing in from the south and west.

Sunday – a backdoor cold front will sweep in from the northeast, bringing cooler, more moist air from the Canadian Maritimes, leading to high temperatures in the mid-40s. Mostly sunny.

Monday – cloudy with a high in the low-40s and increasing chances of rain as a vigorous low pressure system approaches from the southwest.

NYC Weather Update – Jan 15, 2018

NYC, Snow, Weather Update, , , , ,

We have a week of below average cold to contend with before a warm up over the weekend. Two separate chances for snow will take place Tuesday, but neither of these events is expected to drop large snowfall totals.

Rest of today (MLK Jr Day) – cold with high temperatures in the upper-20s and increasing clouds.

Tuesday – temperatures at or just above freezing. Cloudy with a clipper system moving through and bringing chances for light snow accumulation of around an inch.

Wednesday – snow chances continue into the first part of the day as the clipper system transitions into a coastal low. Overall snow accumulation not expected to exceed 2″ at this time.

Thursday – mostly sunny with high temperatures just above freezing.
