Showers and thunderstorms move through the region later today. The weekend begins with mild weather before a brief cool down on Sunday. Warmer temperatures arrive again to start the week before the next chance of rain Monday night into Tuesday.

Rest of today – mostly cloudy as a cold front approaches from the west. South-Southwest winds ahead of this front will bring warm air and raise high temperatures into the mid-upper 70s except south-facing shorelines. Rain from this system does not appear to reach the area until later this evening, around 6-7PM after which rain becomes steadier into the overnight hours.

Saturday – clouds decrease as the storm system above moves off to the east. Temperatures a bit cooler in the low-mid 70s, but still a very nice day. Steady north wind will cool things off, and clear skies overnight will allow temperatures to drop back into the upper-40s for the city and even colder in the suburbs.

Sunday – with such a cool start to the day, temperatures will struggle to break 60ºF despite plenty of sun.

Monday – a shift in wind direction to the south with a high pressure system to the southeast means warmer temperatures Monday with high temperatures climbing back into the upper-60s.

Wet, but much warmer weather today gives way to another blast of cold air this weekend. Light accumulating snow (1-3″) will be a real possibility Saturday and Saturday night before temperatures moderate back closer to season averages for this time of year to start next week.

Rest of today – cloudy, with gusty winds up to 40-50mph from the south and southwest. High temperature in the low-60s. Periods of rain with some thunderstorms possible this afternoon. The first batch of this rain will come in a line around 1PM this afternoon, with a second round of rain hitting later this evening at around 9PM.

Friday – temperatures cool off into the mid-50s with a very small chance for lingering showers and mostly cloudy skies. Overnight lows will drop into the mid-30s.

Saturday – a reinforcing arctic front will sweep through during the day on Saturday, such that high temperatures will peak early in the upper-30s before dropping into the low-30s into the 20s overnight. Precipitation will start off as snow at the coast, transition to rain for a period during the afternoon, but then turn back to snow late in the day. When it all settles, we could have 1-2″ of snow on the ground here in the city.

Sunday – skies clear out with high pressure taking control after the storm passes on Saturday, but temperatures will be cold, only the mid-40s.

Monday – an advancing storm system from the west will shift winds to the south and allow for temperatures to rise back to seasonal averages in the mid-50s.

I thought we had seen the last of the snow this spring, but winter stubbornly will not give up. This week, we’ll see the coldest weather we’ve encountered since the depths of winter, with low temperatures dropping into the upper-20s in the city and even teens for outlying areas. A brief warm up occurs this Thursday before the cold returns again.

Rest of today – windy with periods of rain in the city. High temperatures will likely top off in the upper-40s to near 50ºF. Temperatures plummet into the upper-20s following the passage of the cold front that’s responsible for this round of precipitation.

Tuesday – clear skies will belie the much below normal high temperatures for the day which will be only around 40ºF. A freeze warning is in effect for most of the coastal regions in the Tri-State area given the overnight lows that will be substantially below freezing.

Wednesday – the high pressure pictured above will be in firm control Tuesday and overnight into Wednesday. A cloudless sky overnight will make for ideal conditions for radiational cooling, resulting in low temperatures again in the mid-20s. High temperatures will be warmer in the mid-40s with increasing clouds ahead of the next storm system.

Thursday – a surge of warmer air will accompany the next storm system to impact the area Thursday. This storm system will bring widespread rain and even some thunderstorms late in the day Thursday. High temperatures should reach well into the upper-50s and near 60ºF.

Friday – following the passage of the storm on Thursday, temperatures cool off again into the upper-40s under mostly cloudy skies.

Easter weekend will be bookended by wet weather, but the weekend days themselves should be dry with temperatures around average for this time of year.

Rest of today – an earlier round of showers passed through earlier this morning. Another round of showers and scattered thunderstorms will pass through the region along with a cold front in the afternoon hours. It appears that there will be a good chance for rain between the hours of 12PM-6PM, after which skies should gradually clear.

Saturday – a cooler airmass will take over following the cold front today, so temperatures to start on Saturday will only be around 40ºF. Under mostly sunny skies, the high temperature should still hit normal levels in the low-50s.

Sunday (Easter) – clouds will be on increase for Easter, though no rain is expected. High temperatures will range in the mid-50s.

Monday – our next shot at rain arrives Monday with a warm front and a low pressure system moving up the eastern seaboard. Temperatures will be a bit warmer, in the upper-50s.

Meteorologically, March is a month of highly changeable weather that can swing from one extreme to another. Thus far this month, we’ve seen snow, and record warm temperatures near 80ºF. This week is no different, and it ends with the possibility for a significant coastal storm that could bring accumulating snow to the region to ring in the official start of spring!

Rest of today – warm, with partly sunny skies and high temperatures in the mid-60s. An unstable atmosphere looks primed to spawn a few scattered thunderstorms. Atmospheric dynamics are supportive of strong wind gusts and possibly small hail with any storms that form this afternoon. Some of these storms could approach severe limits. Based on the latest High Resolution Rapid Refresh model output, there look to be two batches of storms, one impacting the region around 2PM, then again around 5:30PM. At the time of this post, two storm cells were moving slowly east over southern Bergen County and the western Bronx respectively.

Friday – temperatures cool off into the low-mid 50s tomorrow, with a slight chance again for some afternoon showers, though nothing quite as significant as today.

Saturday – an area of polar high pressure will move over southeastern Canada, setting the stage for the winter storm Sunday. Saturday, however, will be a pleasant, sunny day, but temperatures will be below average in the low-mid 40s.

Sunday – all eyes turn to a developing coastal storm/Nor’easter. Forecast models are having a rough time handling this storm, with wide variances noted among some of the models from day to day. Given the uncertainty at this time, only a couple days before the expected onset of the storm, it is difficult to guess at the snowfall accumulations from this storm. One thing that is well understood at this point is that temperature profiles will support a primarily snow event, with some rain mixing in at the coast. High temperatures Sunday will struggle to hit 40ºF. Snow should begin in the morning, mixing with rain in the afternoon Sunday afternoon before transitioning again to all snow overnight. A slight variation in the forecast storm track either west or east could result in dramatically different snowfall totals – more updates to come.

Monday – temperatures rebound back into the mid-40s under partly sunny skies following the passage of this late season snow storm.

NYC Christmas Weather – Dec 22, 2015

Winter officially began yesterday night at 11:49PM, though you wouldn’t be able to tell given the incredibly warm weather we’re experiencing and will continue to experience right through Christmas Day. Forget snow – we’re talking thunderstorms possibly happening on Christmas Eve. Hope Santa’s sleigh is electrically insulated!

Rest of today – periods of rain, heavy at times, and cloudy with high temperatures in the low-60s. Timing of a second round of heavier rain seems to be in the 1-3PM window, after which things will calm down.

Wednesday – another impulse of energy will be arriving Wednesday and we’ll get another shot of rain along with it. The timing of the heaviest rain tomorrow appears to be later in the afternoon, around 4PM and the evening rush. High temperatures very similar to today in the low-60s.

Thursday (Christmas Eve) – a substantial surge of warm, humid air from the Gulf ahead of a cold front (and around the western edge of a high pressure center located in the Western Atlantic) will almost certainly lead to record high temperatures being crushed across the region. We are talking the possibility of seeing high temperatures topping 70ºF, which for perspective is close to 30ºF above average for this time of year. Because of the warmth and humidity, the atmosphere will be unstable enough to support isolated thunderstorms as a cold front pushes through, though coverage will be isolated at best.

Friday (Christmas) – after the cold front moves through Thursday, we’ll cool off a bit and dry out, but we’re still talking about temperatures easily in the low-60s which could lead to more records being broken. For those who love the milder temperatures, this is certainly a big gift.

Temperatures remain very warm to start the week, following a weekend of recording-breaking warm weather this past weekend. However, a true cooldown into temperatures within normal ranges for this time of year (high temperatures in the mid-40s) won’t occur until late this week. When that cool down comes around, we could even be looking at a few snow flurries!

Rest of today – widespread fog has taken hold across the region. Fog is expected to lift by around noon, however, generally cloudy conditions are likely to persist through the afternoon. Warm again with high temperatures in the low-mid 60s – higher if clouds break in any areas inland. Later this evening, we get our best shot at a round of showers and even a couple embedded thunderstorms as a cold front pushes through. Timing for this precipitation looks to be around 8PM this evening.

Tuesday – behind the cold front, skies will clear, giving us a much brighter, but also windier day Tuesday. Still, temperatures remain warm, with highs again approaching the low-mid 60s.

Wednesday – cooler temperatures finally kick in with high temperatures dropping into the mid-50s under mostly sunny skies.

Thursday – a secondary surface low will form over the Southeast, associated with a stronger low pressure that will be over the Hudson Bay area. This low brings us our next chance at precipitation, and will yield a mostly cloudy day, with increasing chances for rain in the afternoon as the day progresses.

The three day weekend ahead will feature some idyllic autumn weather with plenty of sun for outdoor activities if you’re heading out of town on a getaway. The only blemish in this otherwise stretch of superb weather will be a round of showers and thunderstorms entering the city Friday afternoon and passing through Friday night.

Rest of today – we’re starting off with mostly cloudy skies, but skies should clear rapidly within the next couple hours. After that, we get a mostly sunny afternoon with high temperatures near 70. Clouds re-enter the picture later this evening in advance of an approaching disturbance that will bring us rain on Friday.

Friday – overnight tonight, a warm front will push through the area, such that by Friday morning, winds will switch to the southwest. This will allow for warm air to surge up ahead of a cold front that will be passing through Friday night. This setup is favorable for the possible development of thunderstorms ahead of the cold front. Chances for rain increase steadily Friday into Friday night. Otherwise, mostly cloudy skies with high temperatures in the upper-70s to near 80.

Saturday – the cold front moves quickly through the area Friday and by Saturday, skies should clear up, while temperatures cool off into the mid-60s.

Sunday – another picture perfect autumn day with high temperatures in the mid-60s and ample sunshine.

Monday (Columbus Day) – stretch of nice weather continues into Columbus Day, with temperatures slightly warmer in the upper-60s to around 70.

Drought Update

The drenching rains two weeks ago helped alleviate drought conditions over large portions of the Northeast. However, moderate drought conditions stubbornly persist in the NYC metro area, especially in Long Island.

Some much needed rain is falling today, with another round of rain coming this weekend. Friday and Saturday look to be the best days out of the stretch, while Sunday has the best chances for rain. The tradeoff for this wet weather will be noticeably less humid, cooler, and more seasonable conditions to start off next week.

Rest of today – we are currently in a dry pocket which should last through the late afternoon hours. The cold front that is initiating these showers and scattered thunderstorms will be slow to move through. A low pressure center that is riding along the frontal boundary is currently parked over us, and as this low continues to move off to the northeast, additional rain is expected develop and wrap around the backside of the low. With this low and the front lingering, we will likely get another round of widespread showers with some heavy downpours possible again later this evening and into the overnight hours. With the rain and cloud cover, highs will only reach the upper-70s before dropping back down.

Friday – once the low pressure and cold front have passed, conditions should begin to improve quickly. There’s a lingering chance for showers in the morning, but by the afternoon hours skies should be clearing with high temperatures around 80.

Saturday – another cold front and low pressure will follow on the heels of today’s system. The timing of precipitation with this system appears to be trending towards late Saturday evening, and primarily overnight into Sunday. This should allow for a mostly sunny day with temperatures again around 80.

Sunday – showers appear to be likely on Sunday, with an isolated thunderstorm possible as well. High temperatures will be in the upper-70s with the clouds and rain.

Monday – once the storm system passes on Sunday, high pressure building to our southwest will allow cool, dry air from Canada to flow into the area, resulting in temperatures again in the upper-70s, but with mostly clear skies.

Another steamy beginning to week is following on the heels of Labor Day. Today and Wednesday are both days when the temperature could top 90ºF. By Thursday, a strong cold front moves through, bringing the potential for much needed rain and cooling things off considerably for the end of the week.

Rest of today – sunny, hot and humid, high temperatures in the low-mid 90s in the city. Humidity remains just low enough to obviate the need for any excessive heat watches/warnings.

Wednesday – increasing clouds from west to east on Wednesday ahead of an approaching cold front. Temperatures remain warm ahead of the front, generally in the upper-80s with maybe a couple spots topping 90. There could be a few pop up showers and thunderstorms later in the afternoon, perhaps along a sea breeze front in Brooklyn/Queens.

Thursday – widespread showers and thunderstorms will be the order of the day, with cooler temperatures in the low-80s and cloudy conditions. Periods of showers and thunderstorms could persist for extended periods of time, bringing the potential for flash flooding in some locations. Rain ends from west to east gradually during the overnight hours.
