NYC Weekend Weather – Jun 8, 2018

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

We have a weekend of stunning late spring weather on tap, with temperatures above normal to start, then cooling off for the second half of the weekend. Little in the way of rain is possible this weekend, so this is an ideal weekend for all types of outdoor activity, including the upcoming Subway Series and Belmont Stakes!

Rest of today – mostly sunny with high temperatures in the low-80s. Southwesterly flow ahead of a cold front means we will get a milder air mass from the southern US.

Saturday – another nice day with more clouds, but still pleasant warmth in the low-80s. A dry cold frontal passage will signal a shift to cooler conditions for the second half of the weekend.

Sunday – behind this cold front, Canadian high pressure will bring back the influence of a continental polar air mass. This will result in below average cooler temperatures in the low-70s, but with mostly sunny skies. The only blemish on this could be some lingering showers from the overnight passage of a shortwave along the cold front that will settle just south of the area.

Monday – mostly sunny skies and high temperatures in the mid-70s as we begin a week with a warming trend.

This week will see mostly average temperatures, with the exception of a very warm day tomorrow. Later on in the week, remnants of Subtropical Storm Alberto will have an impact on our sensible weather, bringing on an extended period of unsettled weather that carries into next weekend.

Rest of today – high temperatures in the low-70s with decreasing clouds. If clouds break up sooner in the afternoon, we could see warmer temperatures in the upper-70s.

Tuesday – a warm front will move through overnight into Tuesday. Temperatures will be significantly warmer with mostly sunny skies behind the frontal boundary, with high temperatures close to 90°F in the city away from south-facing shores.

Wednesday – mostly sunny still, with high temperatures falling back to normal levels in the mid-70s as a backdoor cold front moves through. This will cause a shift in winds to the east, bringing cooler, marine air onshore.

Thursday – increasing clouds with chances for rain late in the day, high temperatures holding in the mid-70s.

NYC Weather Update – May 21, 2018

We start this week off with above average warmth, which will only be punctuated by one day of cooler, wetter weather tomorrow. High pressure returns from Wednesday through the end of the week, bringing us more sunny weather, as well as temperatures gradually increasing to the low-80s by the end of the week. Looking ahead towards Memorial Day weekend, Saturday looks to be the best day, with some rain chances Sunday and Monday.

Rest of today – mostly sunny, with high temperatures in the upper-70s.

Tuesday – a weak disturbance will move through the area along with a warm front. This will yield rain chances later in the day, with the potential for heavy downpours in stronger storms that develop. With cloud cover and rain, temperatures will be significantly cooler, in the upper-60s.

Wednesday – behind this warm frontal passage Tuesday, temperatures should rebound into the upper-70s on Wednesday with mostly sunny skies.

Thursday – a cold front will push through going into Thursday but high pressure will build quickly and this is anticipated to be a dry frontal passage. Temperatures should remain decently mild with highs in the low-70s and mostly sunny skies.

NYC Weather Update – May 15, 2018

The story of this week will be the continuation of an unsettled weather pattern from this past weekend. Today, we will see a chance for some severe thunderstorms, and more rain chances lurk for us during the rest of this week, even extending into the weekend. Temperatures during this time will vary between normal and below normal depending on the extent of cloud cover and rain.

Rest of today – warm, humid, with a high in the mid-80s. Chances for severe thunderstorms increasing late in the afternoon. The Storm Prediction Center has placed our area in an enhanced risk for severe thunderstorms, with primary threats being damaging “hurricane force” wind gusts, as well as heavy rain. Some large hail and an isolated tornado are not out of the question. High resolution rapid refresh model simulated radar suggests the best timing of when the storms hit NYC will be around 6PM during the evening rush hour. This will make for a messy road home.

As you can feel already, the air is quite saturated (fog earlier this morning confirms this), this moisture-laden air will be one ingredient fueling storm growth later especially as temperatures warm with cloud-free skies allowing solar heating to quickly destabilize this air mass. At the surface, a cold front slowly approaching from the north and west will serve as the trigger that provides the lift necessary for storms to initiate late this afternoon. Aloft, the presence of a mid-level shortwave trough upstream of us will help prime the atmosphere, increasing lapse rates and instability aloft, while providing some additional divergence and lifting for storms. Lastly, late in the day, we will be in the right entrance region of a 300 mb jet streak, another favorable ingredient for divergence and synoptic lift. Winds at all levels above the surface will be fairly strong, producing a shear profile that favors strong winds. However, any discrete storms that form ahead of the main squall line could contain strong rotating updrafts favoring large hail and tornadoes. As usually, best chances for severe weather exist north and west of the city, away from the stabilizing influence of the marine layer near the coast. Storms will likely weaken as they hit NYC precisely due to this.

Wednesday – will be significantly cooler behind the cold front with high temperatures only in the mid-60s. Rain chances continue as the frontal boundary stalls and becomes stationary just to our south, in a similar arrangement to what took place over the weekend. This pattern looks to lock in for the rest of the week, bringing multiple chances for rain with it.

Thursday – a drier day mostly, with some slight chance for showers in the morning, then mostly cloudy with high temperatures rebounding into the upper-70s. Rain moves back in again overnight going into Friday.

Friday – cooler again with temperatures dipping into the mid-60s. Mostly cloudy with more chances for rain during the day as the stationary front mentioned above pushes back north as a warm front.

High pressure hangs around the region most of the week and gives us pleasant, seasonable weather with high temperatures at or above average for most of the week. One chance for rain comes in the late week period with a cold front forecast to pass through the area. Otherwise, it will be a marvelous week of ideal spring weather.

Rest of today – mix of sun and clouds with high temperatures in the upper-60s.

Tuesday – mostly sunny with high temperatures in the upper-60s. This week, we benefit from cooling onshore breeze due to the synoptic set up over the Northeast. Contrast this to last week when we had very warm winds blowing from the southwest.

Wednesday – warmer with high temperatures in the mid-70s and sunny skies.

Thursday – rain chances late as a cold front approaches from the west. Otherwise mostly sunny with high temperatures in the low-70s.

This week started off with a gorgeous, sunny day with above average warmth. Temperatures will remain largely at or above normal, with the exception of tomorrow as a storm system rolls through and brings us some rain. The end of the week may also see a chance for showers, but this will set the stage for us to enjoy another weekend of sunny, above average warmth.

Rest of today – increasing clouds as a storm approaches from the southwest. This increasing cloud cover should result in high temperatures a few degrees cooler than yesterday, topping out in the mid-60s. Overrunning precipitation will begin to fall late overnight in association with a warm/occluded front approaching from the south.

Wednesday – rain, with a thunderstorm possible. Mostly cloudy, and cooler with highs in the mid-50s.

Thursday – partly sunny with high temperatures warming back into the mid-60s as the storm system above exits to our northeast.

Friday – partly sunny with high temperatures again in the mid-60s. A chance for rain with a weaker storm system moving up again from our south.

This work week starts off with a serious soaking rain from a storm system that has impacted a wide swath of the southern US with multiple days of severe weather. Conditions improve tomorrow and Wednesday before another chance for rain on Thursday. The rain this morning has led to the issuance of flash flood warnings, and numerous reports of flooding have already come in, so take caution out there, especially if you’re out on the roads.

Rest of today – rain, heavy at times, with the threat for flash flooding and flooding possible as storms train and hit the same areas repeatedly. Some embedded thunderstorms have been occurring this morning, enhancing the heavy rainfall potential. Some areas could see rainfall rates of up to 1″/hr along with gusty winds in the 40-50 mph range. Temperatures will be rising into the upper-50s as a warm front approaches from the south.

Tuesday – improving conditions as the storm system responsible for today’s rain moves off. Cooler, with temperatures maxing out in the low-50s in the wake of a cold front and mostly cloudy skies.

Wednesday – the best day of this week with high temperatures in the mid-50s and mostly sunny skies.

Thursday – another storm system, albeit weaker, will impact the area. High temperatures should hover in the mid-50s with chances for rain and cloudy skies otherwise.

 

NYC Weekend Weather – Apr 13, 2018

Despite it being Friday the 13th, if you were looking for some spring weather, this happens to be your lucky day. With our region in the warm sector of a large storm system far off to the south and west (which will bring severe weather to parts of the Mid-Mississippi and lower Missouri Valleys today), warm air will be surging from the south. This will give us a great start to the weekend, though things will shift dramatically by Sunday as a frontal boundary dances back and forth across the area. Wild temperature swings of 30ºF are possible with a much cooler day Sunday.

Rest of today – despite the cloud cover now, temperatures should still reach well into the mid-70s. Any breaks in the clouds would likely result in highs hitting 80ºF. There will also be a steady southerly breeze with gusts up to 20 mph.

Saturday – temperatures remain quite warm with highs again in the mid-70s. The warm front that swept north through the region last night, which brought the warm air along with it, will retreat south of the area as a backdoor cold front late during the day Saturday. Expect temperatures to drop rapidly after this backdoor cold front passes through – between 10-15ºF within as little as an hour. Increasing clouds will accompany this frontal passage.

Sunday – significantly cooler with easterly onshore winds in the wake of the backdoor cold front passage. This onshore flow off the still cold waters of the Atlantic will result in high temperatures only in the upper-40s. Periods of rain will also occur, especially later in the day with mostly cloudy skies otherwise.

Monday – the backdoor cold front will stall just south of us, then push back north as a warm front again. Temperatures will rise back towards around 60ºF prior to the arrival of a stronger cold front. This will be accompanied by steadier rain and even a couple rumbles of thunder are possible.

 

NYC Weather Update – Apr 2, 2018

NYC, Rain, Snow, Weather Update, , , , , , , ,

I had trouble typing the date in the title of this post, given that there’s snow falling as I write this! Unfortunately, this snow is not a belated April Fool’s joke. Didn’t have time to post an update about this yesterday, sorry about that! I’ll also be out this weekend for weddings. Now on to the weather: look ahead to a week of up and downs in temperatures and active weather, but no more snow. The weekend coming up… well, there could be some chance for snow again Saturday.

Rest of today – snow departs the city by the lunch hour. Around 3″ of total accumulation, mostly on untreated surfaces, before the sun breaks out and starts immediately melting the stuff. High temperatures in the low-40s with decreasing clouds.

Tuesday – rain associated with an approaching warm front. Cloudy, with temperatures in the mid-40s. Overnight temperatures actually don’t go down much before warm air surges as we enter the warm sector of this second storm of the week.

Wednesday – more rain, this time with a chance for a rumble of thunder with decent lifting associated with the cold front that’s part of this storm. Significantly warmer, cloudy, with high temperatures around 60°F.

Thursday – much cooler behind the cold front, temperatures only in the upper-40s with mostly sunny skies.

This will be the first week in almost a month that we don’t get a nor’easter that brings us snow. In fact, temperatures will trend upwards through the week. There’s a chance we could hit 60°F later in the week with some spring showers headed our way.

Rest of today – sunny, high temperatures in the mid-40s.

Tuesday – another bright, sunny day with temperatures a touch warmer around 50°F while high pressure remains firmly in control.

Wednesday – slight chance for rain, mostly cloudy with a frontal system approaching from the west but stalling. High temperatures around 50°F.

Thursday – mild, partly sunny, with high temperatures in the upper-50s behind a warm front.
