When do you think the latest date is that really cold weather can strike New York? That depends on how you define "really cold" but this graph of every January through March daily temperature since 1971 has the answer. The squiggly line is the mean and that bottomed out a couple weeks ago at 29 degrees. Following the January Thaw, the curve reaches another nadir on February 5th before beginning a slow increase. We should dutifully point out that the thaw, like all the day-to-day squiggles in the line, is not statistically significant -just look at that variability. From a climate perspective there is still a chance of cold weather, but the odds are against us having a brutally cold week like what happened in 1979.
Sunny And Mild Weather For The Giants' Ticker Tape Parade
Blizzard In Colorado, Sunny Skies in New York
Since today is the twelfth straight day of warmer than normal temperatures we've taken to enjoying winter vicariously. Blizzard conditions and up to two feet of snow are expected to fall on Denver and eastern Colorado today. Here in New York we should see lots of sun early on and maybe a few clouds invading late this afternoon. With a high of 45 degrees it won't be as warm as the past few days.
A Few More Mild Days Before Winter Begins
Record highs were set or tied all over the region on Saturday except for Central Park, where the high of 62 fell two degrees short of the record set in 1907. While the weather is expected to remain warmer than normal for most of this week, no records are anticipated and things are looking good for a return to more seasonable temperatures by the weekend. Despite the cool start this morning, plentiful sun throughout the day should warm the city to the lower 40s this afternoon. The warming trend continues through mid-week with highs in the upper 40s tomorrow and near 50 on Wednesday. Then things begin to change.
There's No There There In That There Forecast
A weak area of low pressure will pass through the region late Saturday. Be on the lookout for a cloud or two! Another dry air mass will follow on Sunday. This one doesn't have much cold air. Sunday's high will be in the mid 40s under sunny skies and the temperature on Monday is expected to stay in the low 40s. That's a couple degrees warmer than average.
Cool Weekend Begins With A Brisk Friday Breeze
The shadows are long in mid-December. The weak sunlight can't much compete against a cold air mass and gusty winds, so at best we'll see the temperature hold steady for a few hours today before dropping to near 40 degrees by late afternoon. A quick look at the surface weather map this morning shows a low developing over Atlanta. As that moves offshore it normally would be a candidate for a nor'easter, but the high pressure system that will be over us the next couple of days is going to shunt that storm way out to sea.
Warmer Weather Returns After First Freeze
Hey, you know what happened late on Saturday? Around 11 p.m. the temperature fell to 32 degrees in Central Park. That was the first time the mercury had dipped to the freezing mark since March 29th! For the first two years (yes, we know you shouldn't draw conclusions based on two years of data) of the 2010s the date of first freeze is two weeks later than it was in the 1990s and nearly a month later than in the cold decade of the 1970s.
Dry Weekend For A Warm, Wet Year
Despite a cold front tonight we are going to have another dry weekend. High pressure overhead means a sunny day with a high in the lower 50s. A cold front that stretches all the way from Quebec down into Mexico is going the pass through the city tonight. It's a dry front so all that's going to happen is the wind is going to become gusty and northerly and Saturday will be cooler with a high in the upper 40s. The temperature should rebound to the mid 50s on Sunday afternoon.
Another Sunny And Warm Fall Day
It was the easiest of forecasts, it was the hardest of forecasts, it was the age of sun and warmth, it was the age of clouds and rain. Today's forecast is pretty easy. High pressure sitting off the coast will bring another warm and sunny day. The wind swinging around and coming off the ocean will keep today a bit cooler than yesterday. Look for a high around 65.
Marathon Of Sunny Skies Continues!
It's as if November is trying to make up for the cloudy, rainy weather we had in October. After a sun-filled weekend we've got us another couple days of clear skies ahead. High pressure sitting off the New Jersey coast means plenty of subsidence over the region and with subsiding air you get clear skies. The slight southwesterly flow will push today's high to near 60 degrees. Perfect weather to observe the 71st anniversary of a weather-related disaster. A bit of a windshift overnight will push Tuesday's high to the mid 60s.
Cold Front Brings Clear Skies For Several Days
Looking at the hourly observations in Central Park it appears that the cold front passed through the city between four and six this morning, but that it took until almost ten a.m. for the cool Canadian air mass behind the front to arrive. You don't need to look at a website to know that we've now got a healthy north wind. The dew point has also dropped considerably, which means that after an afternoon high in the mid 50s we'll see a chilly night tonight. Look for the temperature across the city to be in the upper 30s tomorrow morning.
Clear Skies For Early November
This satellite image from Sunday morning was too pretty to pass up. There's all sorts of stuff going on, the most obvious being the early season snow cover from Saturday's storm. The big white blob over western Pennsylvania is fog rolling inland from Lake Erie. Over Lake Ontario toward Syracuse is a band of lake effect clouds. Off the East Coast you can see how many miles dry air had to travel before it got saturated by water evaporating from the ocean surface.
A Weather Treat For Halloween
Time for storm fun facts! The 2.9 inches of snow that was measured in Central Park on Saturday makes this the snowiest October ever, more than tripling the previous record of 0.8 inches in 1925. The snow and rain combined to bring us two inches of precipitation, pushing this year's total to 65.75 inches. That's enough to make this the third wettest year since records began in 1869 and two feet of precipitation more than normal. With two months to go we are a little more than an inch away from knocking 1972 out of second place. Unless there's a sudden, severe, drought we'll eclipse that but first place, 80.56 inches in 1983, is probably out of our grasp.
Summer Weather For A Fall Holiday
Yesterday's high of 84 degrees came within two degrees of tying the record high at Central Park. Record highs were set at JFK, LaGuardia, Islip, and Newark, but all of those stations have been taking observations for a much shorter time than the park so records there aren't as impressive. Although the ridge of high pressure that's produced all the sunshine and warmth is beginning to flatten, this afternoon will still see another summer-like day with highs in the lower to mid 80s across the region. A few thin cirrus clouds may build in over the course of the day but they won't much affect the temperature.
Extremely Pleasant Fall Weather For The Weekend
This may be the most boring, yet enjoyable, weather post we've ever written. A high pressure system at the surface and a ridge of high pressure aloft means that clear skies will rule today, tomorrow, Sunday, Monday and probably Tuesday. We should see a high in the upper 60s this afternoon which is just about normal for this time of year.
Clear Skies In Town For Extended Stay!
Hey, look, microwaves bounce off more than just raindrops and snowflakes. The National Weather Service posted the above radar image to their Facebook page yesterday. That donut over the North Fork of Long Island was the return signal from tens of thousands of birds taking flight.
More Sun To Start September
How about a bit of Irene weather trivia to end the month? It was little noted but a post-storm analysis by the National Weather Service confirmed that a weak tornado touched down in Cunningham Park in Queens during the height of the storm. The tornado's peak wind speed was estimated to be 85 mph. Rainfall across the city averaged roughly six inches. Do you know how many gallons that is?
A Dry Week Ahead, Possibly Followed by Hurricane Irene
Nearly two inches of rain over the weekend making this month the second rainiest August on record in Central Park. We're now only 0.77 inches behind the 1995 record of 12.36 inches. With ten days remaining and hurricane Irene potentially coming up the East Coast there is a fighting chance we'll break that old record.
The Sun Returns For A Day
What's that shiny object in the sky? Don't look, you'll hurt your eyes, but we have it on good authority it is the sun. High pressure will give the city a day or so of clear skies before clouds and more rain return. Speaking of rain, 9.61 inches has fallen so far this month, making it the fourth wettest August on record. Assuming the forecast is accurate (ha!) we should easily surpass 1927 to move into third place by the weekend. Almost three inches of rain is needed to break 1990's record of 12.36 inches. Can we do it?
Weekend To Start With Sun, End With Rain
If you haven't done so already, today would be a really good day to call in sick. High pressure centered over Lake Erie means a warm, dry and sunny summer Friday. Look for a high in the mid 80s and perhaps a smattering of fluffy cumulus clouds late this afternoon. Clear skies tonight will make for perfect viewing of the Perseid Meteor Shower.
Dry Weather Today, Humidity Returns Tomorrow
In addition to being hot, this July has also been pretty dry. So far only half the normal rainfall has fallen in Central Park. Perhaps the lack of precipitation explains why we've seen almost literal panic in the streets a couple of times when it has started raining recently. There's no meteorological reason for panic today. High pressure is approaching from the west and that means a dry northwesterly breeze, sunny skies, and a near-normal high around 84 degrees.
Picture-Perfect Summer Weather This Weekend
Did you know that you can follow the local National Weather Service on Facebook? Did you know that the annual NWS Open House at Brookhaven National Lab is just three weeks away? Did you realize there's absolutely nothing happening on the local weather scene this weekend?
Sunny Weekend To Follow Friday Rains
The laziest front ever is still slowly approaching the city today, and its languid approach has allowed lots of moisture to gather in the area. The dew point is hovering around 70 degrees and the precipitable water, which is the amount of water that could be condensed from the air above our heads, is approaching two inches. With all that water it won't take much of a disturbance to get some rain falling. Look for an increasing chance of showers and thunderstorms from this afternoon until about midnight. Some of that rainfall is likely to be intense primarily because we forgot to bring an umbrella to the office. The heavy cloud cover will keep this afternoon's high to the lower 80s.
Sun, Sun, And More Sun On The Way
A cold front passed through the city very early this morning, sweeping away most of the humidity. The dew point temperature has been steadily dropping from its disgusting peak of 73 degrees at 3 a.m. and will continue to do so for the rest of the day. The lack of humidity and clear skies except for a few fair weather cumulus, means we should warm up nicely to the mid 80s this afternoon.
Sunny, Warm Weather Returns
Summer weather returns! Not the unbearably hot and sticky stuff either. Thanks to a cute little high pressure system centered over Southern Ontario we should have a mostly sunny afternoon with a high in the low 80s. Tomorrow should be a wee bit warmer and more humid, but still very pleasant.
Weekend Weather: Sunny Saturday, Cloudy Sunday
It's a pretty simple forecast for the next couple of days. The cool Canadian air mass that's bringing all the sun to the city will stick around through tomorrow as it tries to dislodge a low pressure system that's meandering southeastward from the Canadian Maritimes. The high and low are close enough to each other today to give us brisk northerly winds. With that breeze today's high will probably be restricted to the mid 70s.
Cloudy Mother's Day Weekend Expected
Mostly sunny skies are expected today as high pressure takes a brief pause over the Mid-Atlantic region. It's dry as a bone out there, with the dew point currently running about thirty degrees under the air temperature. Combine that dry air with a brisk west wind and there's an elevated threat for fire spread according to the National Weather Service. Today's high will be in the lower 70s.
Storm Gone, A Sunny, Dry Weekend Is Expected
Now that yesterday's scary looking, but ultimately not all that damaging (unless that was your backyard shed in Denville, NJ) storm has passed, we can look forward to mostly pleasant weather this weekend. There's a slight hitch this afternoon as an upper level trough sweeps through the region. The lower levels of the atmosphere are so dry that the trough will most likely just produce a few clouds, but a brief late afternoon shower or two is not out of the question. Today's high should reach the upper 60s.
Early Spring Snow Fails To Fall, Millions Rejoice
Well that was a pathetic April Fool's joke of a storm. The city may still see rain possibly mixed with snow this afternoon, but the coastal storm is traveling a bit too far east to bring much precipitation to the city. There's still winter weather advisories posted for Orange County and northwestern Connecticut. We've sent our winter loving correspondent John up to Goshen to investigate. Your best bet for seeing snow in the city today is to head up to the observation deck of the Empire State Building. At times that might be high enough to be above the shallow layer of warm air that's melting the snow as it falls. For those of us on the ground we're looking at periods of rain and a high in the low 40s this afternoon.
Cool, Clear Weather For The Weekend and Beyond
Fresh in the wake of yesterday's snow the Times uncovers what must be one of the most obscure bits of weather trivia ever. Yesterday's one-inch snowfall came only six days after the temperature topped out at 77 degrees in Central Park. That's the shortest interval between a 77-degree day and measured snowfall in Central Park. Sadly, they did not ask what the shortest interval is between measurable snow and the next 77-degree day.
Cold and Windy Thursday Coming to Town
Plenty of sunshine again today as there's little moisture in the air. The lack of humidity means we will barely see clouds, let alone rain, when a cold front barrels through town this afternoon. At first the only change the cold front will bring is a shift in wind direction from westerly to northwesterly. Once the sun sets, though, temperatures are going to plummet as there's plenty of cold polar air behind the front. This afternoon's high should be close to 50 degrees. By the time the sun rises tomorrow morning the mercury will be in the lower 20s if not the high teens. Wind chills will likely be in the single digits. Brrr.
