NYC Weekend Weather – May 17, 2019

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

This weekend is shaping up to be similar to last weekend in some respects, with Saturday being a nearly ideal day with plenty of sun, while Sunday is cloudier with some chance for rain. The big difference is unlike last weekend, we’re not anticipating a coastal storm or record-breaking cold! In fact, we should see our first 80°F+ day in some time by Monday before a chance for showers and thunderstorms cools things off.

Rest of today – current visible satellite observations show clouds moving in from the west, so the sunny start to the day will give way to mostly cloudy conditions later. Temperatures will be mild with the influence of warm southwesterly winds, topping out in the mid-70s. Later in the evening, a cold front will push through, bringing a chance for scattered showers and possibly a thunderstorm or two. Overnight lows expected in the mid-50s.

Weather Prediction Center surface forecast for 2PM today

Saturday – even though we’ll have a cold front push through, sinking air behind the cold front and downsloping winds from higher terrain in the north should keep things around average for this time of year in the low-70s with mostly sunny skies. Overnight lows continue to be in the mid-50s.

NAM output for 500 mb height and vorticity, valid for 8AM Saturday. A noticeable reversal of the upper air pattern from earlier this week is visible with a deep longwave trough over the Western US, and ridging over the Eastern US. This will result in great weather for us tomorrow, while areas of the Plains downstream of the trough picture above see the potential for severe weather.

Sunday – warm front approaching from the south during the day Sunday will result in more clouds than sun, and perhaps a scattered rain shower. High temperatures still around average for this time of year in the low-70s. Overnight lows warm up into the low-60s as we enter the warm sector of the storm system approaching us from the west that’s expected to bring severe weather to parts of the Central US this weekend.

Monday – with the region forecast to be in the warm sector of the parent low shown below, and a prolonged period of southwesterly surface winds bringing warm air into the area, temperatures are expected to warm up into the low-80s. This day will have a summery feel, with some humidity to the air and a chance for showers and thunderstorms later in the day as a cold front approaches from the west. Overnight lows should remain mild around 60°F.

NYC Mother’s Day Weekend Weather – May 10, 2019

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

Mother’s Day weekend here in NYC unfortunately looks to be quite rainy. We start off with the potential for rain later today. Saturday is shaping up to be the sole dry day with high pressure briefly building before giving way to a prolonged period of wet weather Sunday and Monday. So, if you’re making any outdoor plans for mom, consider bumping them up to Saturday!

Rest of today – cloudy, with temperatures around 70°F. We will sit in the warm sector of an elongated low centered over western Quebec as a warm front has already passed overhead. This will allow plenty of mild, moist air to stream northward with southerly winds ahead of the trailing a cold front associated with this low. This cold front will serve as the trigger for some showers and thunderstorms later this evening as it swings through. Overnight lows behind this cold front in the mid-50s.

Weather Prediction Center surface forecast for 8PM Friday

Saturday – high pressure briefly builds in during the day. This will give us the best weather of the weekend with mostly sunny conditions and seasonable high temperatures in the upper-60s. Ideal weather for any outdoor activities. This nice weather doesn’t last with clouds building into the overnight hours and low temperatures dipping to the low-50s

Sunday – another storm system approaches from the south. A warm front at the leading edge of this storm seems likely to stall out. This will bring a prolonged period of chances for showers, cloudy skies, and cooler temperatures with easterly onshore winds. High temperatures in the mid-50s. Overnight lows quite cool in the upper-40s as rain chances continue.

GFS model output for 2PM Sunday

Monday – a coastal low forms along the frontal boundary mentioned above. At this time, it appears this coastal low tracks close enough to make Monday another rainy day with cool temperatures, highs in the mid-50s, 10-15°F below normal for this time of year. Overnight lows looking even colder than Sunday if prolonged rain and a northeasterly wind flow materializes with this coastal low, current forecasts pointing to the mid-40s.

The unsettled weather pattern this week continues into the weekend. Rain is possible tonight into Saturday, then again overnight Saturday into most of the day Sunday. Entering next week, it appears we get a break from rainy weather, but looking ahead, another period of prolonged chances for rain could occur mid-week next week. Temperatures will alternate between below normal and around average, depending on whether there is rain in the forecast.

Rest of today – cloudy, with temperatures in the upper-50s. A warm front lingers to our south slowly moving north. Eventually, a cold front will push through overnight into Saturday. This could bring a brief period of rain, and maybe a thunderstorm. Overnight lows in the mid-50s.

Weather Prediction Center surface forecast for 8AM Saturday

Saturday – rain chances should end by late morning. High temperatures should be able to reach around 70°F despite cloudy skies. Another storm system will move in overnight going into Sunday. Rain chances will ramp up steadily after midnight. Moderate to heavy rain is possible. Temperatures overnight in the mid-50s.

Sunday – washout of a day as low pressure moves though. Plenty of moisture available for this system and that could lead to some heavier precipitation. Poor conditions for the Five Borough Bike Tour, with highs around 60°F, as a cool onshore easterly wind accompanies this storm. Overnight lows in the low-50s.

Monday – nice rebound day with high temperatures reaching to around 70°F. Finally should see some sun with high pressure briefly building in the wake of Sunday’s storm and before the next frontal boundary to impact the area. Overnight lows in the mid-50s.

A wet start to the weekend this Friday with multiple rounds of rain moving through. Saturday shapes up to be a better day at least in terms of being dry. A second disturbance/low moves through Sunday bringing yet more chances for rain before skies clear up to start next week. Temperatures behind this second storm/cold front will be below normal for this time of year.

Rest of today – periods of rain during the afternoon as a warm front works its way across the area. Some thunderstorms possible. Second round of more focused/heavier rain later in the evening around 7-8PM as a trailing cold front pushes through. This front will have decent upper level support with some indications of a vorticity maxima at 500 mb and us being in the exit region of a 300 mb jet streak. High temperatures today topping out around the upper-50s even with the rain as we’re expected some time in the warm sector of the low bringing us this stormy weather. If the warm front below fails to push north through here though, we may only see temps in the mid-50s. Overnight lows should bottom out around 50°F.

Saturday – with the trailing cold front clearing the area tonight, precipitation should end and Saturday should end up being a decent day though with more clouds than sun. High temperatures should be able to get into the low-60s, edging into the mid-60s if more sun breaks out. Overnight lows noticeably cooler with a colder, drier airmass behind today’s cold front, in the mid-40s.

Sunday – a second low approaches from the Ohio Valley, again bringing some potential for rain. This rain is expected to be on the lighter side. Temperatures should reach into the upper-50s. Overnight lows in the low-40s.

Weather Prediction Center’s surface forecast for 8AM Sunday

Monnday – start of next week should be sunny, with Sunday’s storm system moving offshore. High temperatures will be below normal though, with the cold front associated with Sunday’s low bringing a reinforcing shot of cooler air. High temperatures probably topping out in the upper-50s. Overnight lows in the mid-40s.

A slow-moving storm system will impact the area with potentially heavy rain that could trigger flash flooding overnight into the first part of Saturday. Precipitation chances die down significantly with the passage of this round of rain as a dry slot works into the area. However, lingering chances for showers still exist as this storm makes a slow exit to the east. Temperatures during this period are forecast to be at or above normal.

Rest of today – cloudy, but still warm with temperatures rising to about 70°F. We will be in the warm sector with the influence of southerly winds during the day. Rain chances increasing during the evening hours. Steady rain is forecast late into the overnight hours with temperatures. Some of the rain could be heavy. Thunderstorms are also possible, and these would increase the risk of flash flooding. Overnight lows around 60°F.

Weather Prediction Center surface forecast for 8AM Saturday

Saturday – the north-south orientation of the cold front that will provide lift for these storms overnight will align well with the prevailing southerly flow through most of the atmosphere. The slow eastward progression of this front will allow storm cells to train leading to more flooding potential as rain continues Saturday morning. The cold front associated with this slow-moving low should push through by the afternoon. A dry slot should cut off any precipitation for a while during this time frame. High temperatures should be in the low-60s. Overnight lows should fall into the low-50s behind the cold front.

GFS model output of 850 mb winds and relative humidity for 2PM Saturday, notice the pronounced area of browns, indicating very dry air. This is what is referred to as a “dry slot“, which can often follow on the heels of cold fronts associated with mature mid-latitude cyclones.

Sunday – the upper low associated with this storm system is expected to cutoff (become detached from primary westerly steering currents), resulting in a system that will meander and take a long while to exit the region. As such, Sunday is expected to remain cloudy, with a chance for some showers. High temperatures should be similar to Saturday in the low-60s. Overnight lows will again be around the low-50s.

Monday – temperatures warming up into the upper-60s, but yes, that cutoff low still lingers! Chance for showers continues in the morning. Clouds finally decreasing later and overnight lows in the mid-50s.

NYC Weekend Weather – Mar 29, 2018

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

We will have a warm though not too sunny start to the weekend. A solid chance for rain hits Sunday with the passage of a cold front. After that, temperatures will drop to below normal levels again. Looking ahead into next week, there should be a dry start to the week but a coastal storm may impact the area mid-week. There’s some outside chances for snow with this storm.

Rest of today – cloudy, with some chance of light rain though most rain should remain over interior. With southwesterly flow, despite clouds we should still reach into the upper-50s to 60°F. A cold front approaching from the west is forecast to stall out and acquire semi-stationary characteristics. Thanks to the continued influence of high pressure off to our east, we should stay mostly dry today. Overnight lows should be warm, near 50ºF.

Saturday – the warmth continues, with high temperatures forecast to reach well into the upper-60s though clouds will still linger around with the stationary front to our west. Overnight lows will be similar to tonight around 50ºF.

Weather Prediction Center surface forecast for 8AM Sunday

Sunday – the stalled frontal boundary finally picks up forward momentum and pushes through the area as a cold front. Ahead of it, temperatures will still be mild in the mid-50s. A line of showers is expected with this front during the day. Overnight lows behind this cold front will be considerably colder, in the low-30s.

Monday – dry, sunny weather, but with a chilly start to the day, temperatures are expected to only be in the upper-40s to near 50ºF, slightly below normal. Overnight lows are expected in the mid-30s.

This weekend will see a warm start but then a cool down into the below normal range going into next week. A rumble of thunder and showers will precede this cool down. Weather looks pleasant for St. Patrick’s Day festivities and the NYC Half Marathon this weekend. 

Rest of today – mostly cloudy with some breaks of sun after a warm front passes over shortly and we sit in the warm sector of the same storm that tore through the central US earlier this week. As the trailing cold front pulls through this evening, it could provide enough lift for some additional showers and possibly a couple thunderstorms. High temperatures will be above average in the low-60s, mid-60s if some sun breaks through while we’re in the warm sector. Overnight lows behind the cold front should be in the low-40s.

Weather Prediction Center surface forecast for 8PM Friday

Saturday – bright, sunny day with high pressure building behind the cold front. Temperatures cooler, around 50°F. Overnight lows much cooler in the low-30s.

Sunday – cold start to the NYC Half Marathon in the low-30s but high temperatures will end up in the mid-40s with lots of sun. Overnight lows again around the freezing mark

Monday – increasing clouds with a possibility for some precipitation but chances are too low now to call. Highs in the mid-40s and overnight lows back down in the low-30s again.

As we spring forward this Sunday, our weather pattern finally takes a step forwards towards spring as well. Rain will accompany this warmup, then we start next week with temperatures close to average for this time of year. 

Rest of today – Increasing clouds as an area of low pressure moves offshore well to our south. High temperatures in the upper-30s. A 500 mb (upper level) shortwave trough passing through overnight could provide enough lift for some scattered flurries. Lows dipping to around freezing. 

Saturday – High temperatures in the mid-40s with lots of sun as high pressure temporarily exerts its influence. Overnight lows in the mid-30s. Rain starts overnight going into Sunday as a storm system draws near. 

Weather Prediction surface forecast for 8AM Sunday

Sunday – rain during the morning with improving conditions later. Overcast to start with cloud cover decreasing as the storm departs to the east. High temperatures around 50°F. Overnight lows in around 40°F

Monday – sunny and seasonable with highs in the upper-40s. Overnight lows cooler than Sunday in the mid-30s.

A weak cold front passes through to start the weekend. a decent weekend is in store with a chance for snow showers on Sunday night. Temperatures will be about average for this time of year through Presidents Day. We have a chance for more significant winter storm mid-week next week although details are fuzzy. At this time, thermal profiles at the coast suggest a mixed event like this past week with snow transitioning to sleet, freezing rain and plain rain. This event looks longer in duration due to a slow moving high east of the incoming storm. I will be on vacation next week and won’t be posting until the following week.

Rest of today – overcast with temperatures in the low-50s. Slight chance for rain with a weak cold front passing later in the afternoon. Overnight lows in the mid-30s.

Weather Prediction surface forecast for 7PM Friday

Saturday – mostly sunny with highs in the low-40s. Overnight lows around 30°F.

Sunday – mostly sunny during the day with highs around 40°F. Overnight lows in the low-30s will support some light snow associated with a broad area of low pressure. Not anticipating much accumulation beyond a coating.

Monday (President’s Day) – imoroving conditions. Partly sunny with highs in the low-40s and overnight lows dropping into the low-20s.

A mild start to this weekend will transition quickly to colder temperatures more typical of this the of year. A windy day in store on Saturday in the wake of a cold front bringing us rain today. cold temperatures remain in place into the beginning of next week. No more 60°F+ days in store for us!

Rest of today – rain tapering off by around lunchtime. Mild temperatures with highs in the mid-50s with clearing conditions. Once the cold front sweeps through, winds will pick up from west into the 15-20 mph range. This will advect cold air into the area and overnight lows are forecast in the mid-20s. By midnight, temperatures will be around the freezing mark.
