NYC Weather Update – Jul 23, 2018

Flooding, NYC, Rain, Thunderstorms, Weather Update, , , , , , , ,

Wet weather this weekend continues into much of this week as we settle into a pattern favoring rain chances every day. Tropical moisture remains firmly entrenched in the region due to an anomalously strong upper trough and deep layered southerly flow. A strong high pressure center over the western North Atlantic will block the progress of frontal boundaries until next weekend when we finally get a break from the wet weather.

Rest of today – mostly cloudy, high temperatures in the low-80s. Chances for scattered showers throughout the remainder of the day and into the overnight hours.

Tuesday – mostly cloudy, high temperatures again in the low-80s. Lower chances for rain than the rest of the week due to the high pressure mentioned above retrograding west. This should keep things largely dry.

Wednesday – best chance for sustained bouts of heavy rain as a cold front approaches from the west but stalls out and dissipates. High temperatures in the low-80s with mostly cloudy skies again. Flash flooding could be a concern given the atmospheric water content and the southerly steering currents parallel to the frontal boundary, favoring training of storms hitting the same area repeatedly.

Thursday – yet another day with the chance for showers and thunderstorms, high temperatures in the mid-80s and mostly cloudy.

NYC Weekend Update – Jul 20, 2018

Last weekend’s beautiful, sunny weather will be but a fleeting memory this weekend as a coastal storm hits the area late Saturday going into Sunday. Periods of heavy rain and even some severe weather are possible Saturday night and Sunday, with the potential for isolated flash flooding. Unsettled weather continues into next week with a tropical weather pattern setting up providing daily chances for showers and thunderstorms.

Rest of today – a great start to the weekend, with high temperatures in the low-80s and sunny skies.

Saturday – cool, with high temperatures only in the upper-70s due to the influence of easterly winds ahead of a warm front attached to the advancing coastal storm. Clouds increasing late in the day and rain chances picking up in the evening hours going into overnight. Chance for heavy rain, scattered thunderstorms with gusty winds (even an isolated tornado possible). Gusty east winds will make the overnight hours feel particularly cool and miserable.

Sunday – rain chances continue into the day and even Sunday night. Temperatures increase behind the passage of the warm front mentioned above and winds shifting to the south – high temperatures should be in the mid-80s with mostly cloudy skies. All told, we could be looking at widespread rainfall totals of 1-3″ across the area.

Monday – showers likely again as temperatures remain in the mid-80s under mostly cloudy skies. A strong upper-level trough will be wedged between two areas of high pressure. The one off to our east over the western North Atlantic will continue to strengthen over the course of the week, blocking the eastward advance of this upper trough. This effectively will result in an extended period of southerly flow, with moist, tropical air coming our way. Multiple impulses of energy are expected to travel along this strong upper-level trough. Each one will bring with it a chance for showers and thunderstorms. This pattern does not appear to break until next weekend, although it’s not as though each day will be a washout either.

 

NYC Weather Update – Jul 16, 2018

This week starts off hot and humid before we get a break from the humidity as a cold front rolls through late Tuesday. This will be a relatively strong front, and with plenty of moisture in place prior to its passage, bouts of heavy rain are possible with the thunderstorms accompany it. Although high temperatures won’t dip too much following the cold front, dew points will, and this will bring a much drier and more comfortable feel.

Rest of today – hot, humid, with high temperatures in the low-90s. A heat advisory is in effect due to the combination of hot temperatures and high dew points making for an oppressive, muggy day.

Tuesday – increasing clouds, high temperatures in the upper-80s prior to the onset of showers and thunderstorms later in the afternoon, going into the evening hours and overnight. The set up of the atmosphere tomorrow could allow for some marginally severe storms to develop. The primary threat will be from heavy rain and some strong wind gusts given the moisture in place and somewhat favorable shear.

Wednesday – mostly sunny with highs in the mid-80s but more comfortable with dew points significantly lower behind the cold front. Refreshing northerly winds should make for a nice day.

Thursday – another great day with sunny skies and with highs in the mid-80s.

NYC Weekend Weather – Jul 13, 2018

Friday the 13th might be bad luck but not in terms of the weather this weekend. High pressure will only be briefly interrupted by the passage of a weak cold front late Saturday into Sunday. Not much in the way of rain expected with this front. Looking ahead, next Tuesday holds the best chance for appreciable rain. Temperatures will be on the warm side until late next week.

Rest of today – mostly sunny and warm with highs in the upper-80s.

Saturday – mostly sunny then increasing clouds late as a cold front approaches. Highs around 90°F.

Sunday – slight chance for thunderstorms early, then partly sunny, highs in the upper-80s.

Monday – mostly sunny, highs in the upper-80s again.

Just as we get ready for the week of Independence Day, the heat really gets turned on. We anticipate the first heatwave of the summer with temperatures in excess of 90°F expected for the next 5 days. This will be an exceptional weekend for a beach getaway!

Rest of today – sunny, and hot, with high temperatures generally a touch or two above 90°F.

Saturday – heat increasing, sunny, with high temperatures in the mid-90s. Humidity also builds.

Sunday – hottest day of the weekend as robust south-southwesterly flow around a high pressure center to our south pumps lots of hot, humid air our way. High temperatures in the upper-90s.

Monday – still no relief, with high temperatures in the mid-90s and sunny skies.

This week starts off with a string of pleasant, dry conditions with Canadian high pressure in control. Temperatures will be a bit below normal due to the cool influence of this continental Canadian air mass. We get a chance for some rain mid-week, then temperature start warming up. Looking ahead, we could be seeing an extended period of 90°F+ temperatures starting the end of this week.

Rest of today – mostly sunny, high temperatures around 80°F.

Tuesday – another great day with high temperatures just about 80°F and lots of sun.

Wednesday – increasing clouds as the next storm system approaches the region. High temperatures again about 80°F.

Thursday – overnight into Thursday, rain chances start to pick up as a warm front approaches the area from the southwest. This will lead to chances for showers and thunderstorms, which will continue into Thursday. High temperatures will remain around the 80°F.

We got to enjoy one weekend last week where it didn’t rain at all. Unfortunately that won’t be the case this week with a storm passing through tomorrow. Temperatures will be cool with the influence of an onshore easterly wind before the passage of a warm front that will bring the chance for rain and thunderstorms.

Rest of today – cool, cloudy, with a high in the mid-70s.

Saturday – cloudy, with chances for rain and thunderstorms especially later in the day. The best chances for thunderstorms come with elevated convection late in the day and going into the overnight hours as a warm front approaches from the south. Temperatures will be cool in the mid-70s again.

Sunday – improving conditions with warmer temperatures in the warm sector after the passage of the warm front. Highs should reach into the mid-80s, possibly higher depending how much sun we get.

Monday – Canadian high pressure returns in the wake of this weekend’s storm and gives us sunny weather with mild temperatures in the low-80s.

NYC Weather Update – Jun 18, 2018

A sultry start to this week will lead to cooler and more pleasant weather as the week wears on. We have two chances for rain, overnight tonight and then overnight Wednesday. Overall, it appears to be a dry week, with another unsettled weekend coming up.

Rest of today – hot, humid, with high temperatures in the mid-90s. We could set or break a record for Central Park today at 95ºF. A cold front approaching later tonight could touch off some strong thunderstorms with the potential for heavy rain given the moist environment. The strongest storms will be limited to areas north of the city, away from the usualy stabilizing marine influence, and where wind shear profiles are stronger. Best timing for showers and thunderstorms will be 8PM tonight with a pre-frontal trough then early Tuesday morning with the actual cold front passing through.

Tuesday – behind this cold front, clouds should clear up, though tomorrow is still expected to be quite warm with high temperatures in the upper-80s. The main difference will be lower dew points that should result in a decidedly less muggy feel to the day.

Wednesday – warm with high temperatures in the mid-80s and partly sunny skies. A weak disturbance pushing through overnight may bring some rain.

Thursday – nice day with high temperatures in the low-80s. Cooler, refreshing Canadian high pressure will dominate.

NYC Weekend Weather – Jun 15, 2018

A cool start to this weekend will give way to some of the hottest temperatures we’ve seen in a while. We could have a weekend of entirely dry weather for the first time in over 2 months. We could even see a heat wave to start next week.

Rest of today – the headline of the weekend is a dominant area of of high pressure. Today, while the center of the high pressure sits off to our west, we’ll experience cooler temperatures in the mid-70s with mostly sunny skies and northerly winds.

Saturday – the warm up will begin with sunny skies and temperatures in the mid-80s as the center of the high pressure center dominating our weather continues to move east.

Sunday – by Sunday, the center of this high will be to our southeast. This will result in very warm air flowing clockwise around the western periphery of the high, giving us temperatures in the low-90s and sunny skies. Great beach weather! A mid-level disturbance could touch off a couple isolated thunderstorms, more likely inland during the overnight hours.

Monday – the hot weather continues with temperatures in the mid-90s and mostly sunny skies.

A mostly dry, and pleasant week is in store for us. We will see a steady warming trend, with the only real chance for wet weather happening Wednesday accompanying the passage of a warm front and cold front. Great weather lasts right into the weekend.

Rest of today – cool and sunny with high temperatures below normal in the low-70s due to the influence of easterly onshore winds.

Wednesday – a warm front will approach from the southwest. Ahead of that frontal boundary, we could see chances for mainly stratiform showery rain during the late morning hours. Behind this warm front, expect a humid feeling high in the low-80s with mostly cloudy skies until the arrival of the trailing cold front. This second frontal boundary has a better chance to fire off a few thunderstorms, which could be locally strong, late in the evening and into the overnight hours.

Thursday – high pressure returns and gives us a nice sunny day of high temperatures in the low-80s with westerly winds bringing in warmer air from the interior.

Friday – slightly cooler in the upper-70s to around 80ºF but lots of sun again with high pressure staying in control but shifting east.
