NYC Weather Update – Aug 1, 2017

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

We enter the month of August with much more appropriate, summer weather and temperatures to match. High pressure over the eastern half of the country dictates the weather this week, with plenty of sun and temperatures finally in the normal to above normal range in the mid-upper 80s. Humidity increases and results in daily afternoon chances for showers and thunderstorms.

Rest of today – sunny with high temperatures in the mid-80s.

Tuesday – warmer, sunny with high temperatures in the upper-80s to near 90°F.

Wednesday – similar picture to Tuesday with highs in the upper-80s to around 90 °F, chance for an afternoon shower or thunderstorm.

Thursday – cooler with temperatures back in the mid-80s range and another chance for thunderstorms in the afternoon.

NYC Weekend Weather – Jul 28, 2017

After a couple days of average temperatures, this weekend sees a return to cool temperatures with a wet start to it all. Conditions improve Sunday, and high pressure builds but temperatures remain below normal until later next week.

Rest of today – increasing clouds as a coastal low begins to form off the Mid-Atlantic. Warm with high temperatures right around normal in the low-mid 80s. Rain should hold off until the overnight hours.

High resolution rapid refresh model runs don’t show significant rainfall until around 2AM EDT Saturday

Saturday – an unpleasant, raw, windy, rainy day more reminiscent of autumn or spring than late July. As the coastal low moves closer to us along a stalled frontal boundary, it will bring chances for moderate to heavy rain along with a stiff northeast wind around 25 mph. As a result, temperatures will be surpressed in the mid-70s. Rain chances taper off during the day as the low moves east.

Sunday – much nicer with plenty of sun and temperatures rebounding to around 80°F. Still will have a cooling influence of the weakening northeast winds.

Monday – high pressure builds and yields another decent day with high temperatures around 80°F, possibly higher with more sun.

NYC Weather Update – Jul 24, 2017

This past weekend, we saw a heatwave broken by several rounds of moderate to heavy rain associated with a couple frontal systems. In their wake, we start this week with temperatures below seasonal averages. This cooler airmass will dry out midweek and give us very comfortable average temperatures in the low-80s.

Rest of today – one more round of moderate to heavy rain pushing through now, then expect a break from the rain during the remainder of the day before another chance for showers later this evening and into the overnight hours, around 8-10PM. Cool, with am easterly onshore flow. High temperatures in the upper-70s.

Tuesday – high pressure begins to build but may not be sufficiently strong to completely remove the chance for showers especially early. Temperatures remain cool in the mid-70s again with a northeasterly onshore influence and cloudy skies.

Wednesday – warmer and sunny finally with high pressure in control, highs will rise into the low-80s.

Thursday – warmer still and into average high temperatures with highs in the mid-80s, but the tradeoff is increasing clouds.

NYC Weather Update – Jul 17, 2017

We enter a week of weather that will very much feel like summer, with temperatures warming up during the midweek period. Each day, there could be a chance for showers or thunderstorms, though these will be more of the scattered variety. Temperatures return to more seasonable levels by the weekend.

Rest of today – partly cloudy with scattered showers and thunderstorms popping up this afternoon in some spots. A few storms could become strong or even severe. Temperatures in the mid-80s.

Tuesday – another chance for showers and thunderstorms in the afternoon with a weak front in the area, but partly cloudy otherwise and temperatures again in the mid-80s.

Wednesday – warming up with temperatures edging closer to 90°F. Partly cloudy skies, with a chance for showers and thunderstorms again especially during the late afternoon and evening hours.

Thursday – hottest day of the week with temperatures in the low-90s. Partly sunny, and there is a chance for showers and thunderstorms as a cold front passes through the area, but the timing of this frontal passage is as yet not completely certain. Current thinking is that the front passes through overnight into Friday.

Friday – still quite warm in spite of the cold front passing through, high temperatures around 90°F again and mostly sunny.

NYC Weekend Weather – Jul 14, 2017

What a difference a day makes – we went from a high in the low-mid 90s yesterday to a high today 20ºF cooler. Anticipate multiple rounds of rain throughout Friday, but much improved conditions for the weekend itself. We get another shot at rain on Monday to start next week.

Rest of today – cool, cloudy, with an easterly wind and the influence of a Canadian maritime airmass following the passage of a cold front earlier, we will experience significantly below normal high temperatures only in the low-mid 70s. The cold front will stick around just south of us during this time, and multiple impulses of energy will ride along this front. This means chances for rain, outside of this morning, most likely again in the early evening hours.

Saturday – early morning fog clears out quickly and gives way to a partly to mostly sunny day with much warmer temperatures in the mid-80s.

Sunday – sunny, with high temperatures in the mid-upper 80s.

Monday – a gradual warmup begins Monday with high temperatures into the upper-80s and a chance for showers and thunderstorms.

NYC Weather Update – Jul 10, 2017

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

This week’s weather will be dictated by a frontal boundary that will dwell in our vicinity, giving rise to multiple days when we could see rain. A warm, humid, tropical airmass will be in place, which adds the potential for heavy rain and maybe some localized flooding. To top it off, Tuesday also holds a marginal risk for severe thunderstorms.

Rest of today – mostly sunny with high temperatures around normal in the low-80s. A warm front lifting northwards brings a noticeably muggier feel later on.

Tuesday – we will be firmly inside the warm sector, wedged between the warm front mentioned above and an advancing cold front. A prefrontal trough will provide the best dynamics for thunderstorm initiation. Storms that do form will have ample energy to feed off, though less so over areas east of the Hudson under a marine influence. Mostly cloudy otherwise, warm and humid with high temperatures in the mid-80s.

Wednesday – partly sunny, with chances for showers. Highs in the mid-upper 80s depending how much sun we see.

Thursday – another day where we could see rumbles of thunder and rain, mostly cloudy and warm again with highs in the mid-80s.

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.
