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

Soggy start to the weekend quickly improves. We should see a seasonable and fair weather weekend in the NYC area, although Saturday carries a chance for some scattered showers and thunderstorms. Sunday will be the better of the two days.

Rest of today – on the cool side with the clouds, highs in the low-80s. The flooding rains we’ve received this morning will subside quickly after lunch and we might even get a little sun later. Another afternoon spot shower or thunderstorm is also possible.

Saturday – a cold front moves through and provides the trigger for some showers or thunderstorms, but do not anticipate a washout like this morning. Mostly cloudy with high temperatures in the mid-80s.

Sunday – mostly sunny with high pressure building behind the cold front. Temperatures again in the low-80s.

Monday – should be another dry day with mostly sunny skies and high temperatures in the low-mid 80s.

The first official full week of summer starts out more spring-like, but heats up towards the end of the week. Along with the heat, chances for rain and thunderstorms also increase, leading to an active weather pattern for there holiday weekend.

Rest of today – mostly sunny with a small chance for a pop-up shower inland, north and west of the city as a weaker cold front moves through. High temperature around 80°F.

Tuesday – a second cold front approaches, weakening as it does so. This front will bring another slight chance for showers and thunderstorms tomorrow afternoon. High around 80°F again.

Wednesday – high pressure builds behind the cold front. Temperatures remain below average in the upper-70s to 80°F with sunny skies.

Thursday – high pressure to the south starts sliding southeast and brings warmer tropical air flowing clockwise around it. This will have the effect of raising temperatures into the mid-80s under mostly sunny skies.

NYC Weather Update – Jun 12, 2017

Main weather headline for the start of the week remains the heat and humidity. We’re in day two of the second heat wave of the year. Luckily for us, relief is not far off, with a cold front moving through Tuesday, a distinct change in airmasses will bring much cooler temperatures for the balance of the week.

Rest of today – sunny, hot, humid, high temperatures ranging from the low-mid 90s across the area with heat index values in the upper-90s. Air quality alert is in effect for high levels of ozone. The only relief from the heat will be on immediate south-facing shores that benefit from a sea breeze.

Tuesday – much the same as today to start off, with temperatures in the low-mid 90s and very humid again. Overnight temperatures going into Tuesday will be quite mild as well. There is a possibility later in the afternoon for a few scattered strong to severe thunderstorms that may pop up ahead of a cold front pushing through.


Wednesday – much cooler and less humid in the wake of the passing cold front. We will feel the cooling relief of a northeasterly wind as a high pressure center over southeastern Canada becomes the primary factor for our sensible weather. Temperatures will top out near 80ºF with mostly sunny skies.

Thursday – temperatures cool off even more into the mid-70s with increasing clouds.

Got retrained as a SKYWARN spotter last night – this weekend should be tranquil though. A steady warming trend begins this weekend and lasts through mid-week next week. After a prolonged period of cool and unsettled weather, we could see the second heatwave of the season. Great weekend for a getaway to the beach!

Rest of today – mostly sunny, temperatures in the upper-70s to around 80º. Some residual instability in the wake of a low pressure center exiting the Northeast may touch off a couple isolated showers or thunderstorms.

Saturday – the warmup continues with temperatures climbing into the low-80s. Isolated showers and thunderstorms are possible again in the afternoon hours with the passage of an upper level disturbance.

Sunday – the heat arrives in earnest as a Bermuda high sets up and begins to strengthen. This will begin pumping in warmer and more humid air from the south and southwest. Temperatures are expected to climb into the low-90s in the city with sunny skies, with cooler temperatures due to the sea breeze on south-facing shores in the mid-80s. Great beach day, and ideal conditions for the annual Puerto Rican Day Parade.

Monday – the heat continues with temperatures again in the low-90s with some spots in the mid-90s and sunny skies. There could be a heat advisory up at some point.

NYC Weather Update – Jun 5, 2017

The beginning of June sure won’t feel like summer with an extended period of unsettled weather through midweek due to the influence of a very slow moving set of low pressure centers. However, forecast models are trending towards a warm up towards the end of the week and going into the weekend.

Rest of today – mostly cloudy with high temperatures approaching 70ºF. Periods of rain possible later in the day along with a couple thunderstorms.

Tuesday – periods of showers likely throughout the day with temperatures much cooler in the mid-50s due to the influence of an onshore, northeasterly wind.

Wednesday – mostly cloudy again, with rain chances gradually diminishing. Cool, with temperatures in the low-60s.

Thursday – finally get a shift in winds away form the northeast. Partly sunny, and warmer with high temperatures near 70ºF.

 

Warmup Ahead

Climate Prediction Center forecasts for 6-10 days out show a pronounced warm up occurring over the Eastern US as high pressure starts to setup over the western Atlantic. This weekend should feature temperatures closer to normal in the upper-70s and low-80s.

This weekend will feature mostly sunny skies, seasonable, and pleasant conditions until late in the day Sunday when our next chance for rain moves in. The low pressure causing this next round of rain looks to linger well into mid-week next week, which will bring on several days of cool, cloudy, and rainy weather to contrast with the beginning of the weekend.

Rest of today – mostly sunny with some slight chance for scattered thunderstorms, most likely appearing west of NYC. High temperatures ranging in the mid-upper 70s.

Saturday – mild, pleasant, mostly sunny with high temperatures in the mid-70s. High pressure will be in control for a day.

Sunday – high pressure starts breaking down as the next storm system approaches. This storm system will be a complex and slow moving one. While the bulk of the moisture associated with this storm looks to stay offshore, we will still get multiple rounds of rain from it, beginning late Sunday. Temperatures will be a touch cooler in the low-70s with increasing clouds Sunday.

Monday – cloudy with temperatures in the low-70s, and periods of rain likely throughout the day. Kicks off a cooler and wetter than normal trend leading at least into mid-week.

Active weather pattern continues this week to open up the month of June, though we aren’t looking at the kind of soaking rains we got last week. Temperatures on a general gradual upwards trend through the week with high temperatures ranging into the mid-upper 70s by the end of the week.

Rest of today – cloudy, with a very slight chance for showers later in the day. Cool with an onshore breeze, high temperatures in the low-60s.

Wednesday – warmer, but still cloudy with chances for showers and thunderstorms during the day as a frontal boundary passes from the west. High temperatures in the mid-70s.

Thursday – high pressure takes control for one solid day on Thursday as temperatures remain in the mid-70s with mostly sunny skies anticipated.

Friday – another nice day to start with mostly sunny skies. Chance of showers and thunderstorms increases late Friday into early Saturday accompanying an approaching cold front. Highs in the upper-70s.

We’re well on pace to hit the low-90s again today, which would officially mark the first heat wave of 2017. The Bermuda high that led to these sultry conditions allowed us to heat up even more than official National Weather Service forecasts called for. Temperatures ranged 20ºF above normal in many places away from south facing shorelines. The weekend sees a drastic change in airmasses and a return to more seasonable conditions before the next chance for rain Monday.

Rest of today – hot, humid, high temperatures reaching the low-90s for most areas again except the south-facing shorelines of Long Island. Air quality has improved today so no alert is active. A cold front passes through the area later this evening, with a chance for isolated thunderstorms.

Saturday – the passage of the cold front late Friday sets the stage for a dramatic shift in airmasses. Behind the cold front, a high pressure center over Canada will bring much cooler air riding winds from the north and northeast. Temperatures Saturday are expected to cool off into the upper-60s, with much drier conditions and mostly sunny skies.

Sunday – another cool day with temperatures in the mid-60s and clouds building ahead of a warm front that will move through Monday.

Monday – a warm front, followed quickly by a cold front pushes through Monday. The result will be mostly cloudy skies and an extended period of showers through the day. Temperatures will be slightly warmer, in the low-70s.

 

 

NYC Weather Update – May 15, 2017

Dramatic changes are in store for us this week with respect to the temperature. Mid-summer heat and humidity reach their apex on Thursday with high temperatures climbing into the mid-upper 80s except for areas affected by a sea breeze. For the first time in a while, we will see an extended stretch of dry weather.

Rest of today – very windy with northwest winds 25mph and higher gusts due to the pressure gradient between this weekend’s Nor’easter exiting east and high pressure building to to the west. Wind advisories are up for the city. High temperatures into the mid-60s.

Tuesday – sunny, and a warmup begins with temperatures climbing to the mid-70s.

Wednesday – warmer still, with lots of sun and high temperatures in the low-80s.

Thursday – the warmest day of the week with temperatures reaching well into the mid-upper 80s. High pressure from earlier in the week will slide southeast and eventually build over Bermuda. This is a classic setup that favors warm and humid conditions on the Eastern seaboard as warm air from the gulf and tropics rushes from the southwest clockwise around the high pressure.

 

Drought Completely Gone

For the first time in a year, no drought conditions existed anywhere in New York State.

Another rainy weekend on tap for the Tri-State area as a Nor’easter takes aim at the Mid-Atlantic and New England just in time to put a damper on Mother’s Day plans. Luckily for us, rain on actual Mother’s Day should be limited to the morning hours. Next week, we’re looking forward to a big warm up in temperatures.

Rest of today – partly sunny with high temperatures topping out in the low-60s.

Saturday – a Nor’easter moves in on the area overnight into Saturday. Expect raw, windy, rainy conditions for the duration of the day. There could be periods of moderate to heavy rain along with east/east-northeast winds in the 15mph with stronger gusts. High temperatures with the onshore flow, clouds, and rain only expected to reach the low-50s.

Sunday (Mother’s Day) – rains clear up earlier in the day, but we’re still left with a windy and cloudy day. The tradeoff is warmer temperatures in the mid-60s.

Monday – partly sunny skies with improving conditions and high temperatures in the mid-60s.

 

Warmup Ahead

Starting Tuesday, temperatures begin to warm up significantly with a shift in our weather pattern. A summer-like Bermuda high sets up and pumps in warm air from the south into the area, resulting in temperatures above to well-above normal (some 80s possible late week).
